Some things just never changed, that was something Shepard knew all too well. That saying applied perfectly with the situation he found himself in. Hoping to enjoy just a bit of time without some kind of high-stakes mission, he was spending shore leave in his citadel apartment and he wasn’t alone. Acting as his roommate for the remainder of his time there was Urdnot Grunt. The tankborn krogan just couldn’t keep himself out of trouble and was now being essentially babysat by the human.

It was much less a leader and their subordinate sharing a space and more like two roommates. They talked back and forth, mostly Grunt going on about some of the best fights he’s had so far while also hoping to have even more. At first he wasn’t happy about being cooped up in the apartment but in time he settled down and enjoyed the amenities along with the entertainment that was available. Shepard allowed him to have whatever he wanted so long as he didn’t break anything.

Handling the restocking of food and other needed things around the apartment himself, Shepard would leave the krogan alone and would be pleasantly surprised to find the place in one piece. And Grunt was pleased to have more refreshments. If he couldn’t go out and get into scrapes himself he could at least gain something from the provided entertainment, watching plenty of action and violence both real and fake. Turns out it wasn’t hard to keep him put.

There was a hiccup when it came to finding something for Grunt to wear other than the bulky armor he was usually clad in. He was permitted to relax and even if he didn’t fully grasp it at first Shepard insisted and helped, starting out with getting something more casual for him to wear. Even if there was a shirt big enough for him to put on there was no way it was getting over his head.

But after some extensive searching a pair of sweatpants were found that seemed suitable enough for him to wear. Grunt took them but was adamant on getting changed in private. When he eventually came out he was going bare from the waist up and the pair of sweatpants covered the rest, fitting but clearly snug against his body. It was no small wonder as to why that was.

The first word that came to mind when asked to describe a krogan was “huge” and they lived up to that term in every way, clearly built to fight and they were damn good at it. They all stood tall and broad, their muscles showing through the gaps in their armors. Though their race was going through many problems there were times when Shepard felt jealous or even wished he could be one. Not just for the added power but also because of the unique trait their kind was keen on bragging about, being their set of quads.

Seeing Grunt on the couch without anything covering his upper half and that tight fitting pair of sweatpants with nothing underneath was putting an image in Shepard’s mind. It was hard to not notice the imprint that was by no means subtle but even then it got him wondering what it really looked like as he couldn’t ever recall seeing Grunt in the nude. This stayed on his mind as the day passed. Grunt was completely unaware, having his attention on the entertainment provided and the drinks that had been provided. In time he had fallen asleep and Shepard walked past but then stopped, seeing what looked like his chance to perhaps get that answer he had been pondering. It would be just a peek, so quick that Grunt wouldn’t realize.

With his focus on Grunt’s bulge, Shepard came in slowly and even got down on his knees as he was put in front of the snoring krogan. The closer he got to his friend, the more excited he felt himself becoming for some reason. It wasn’t as if he was doing anything more. After taking a deep breath to calm himself a bit, Shepard reached out and took hold of the waistband, slowly but firmly pulling it down.

He did this because the bulging outline was promising something worth seeing but when he actually got a full view of the created krogan’s exposed cock and balls was something else entirely. Shepard’s eyes went wide as even in a flaccid state the shaft was huge and sitting snug below it were the famous quads, each one of them looking about the size of a prime ripe orange.

It was one thing to have a pair but having four balls in total, all of them being that big, making the sack huge in total. He knew that they would be huge based on the bulge but he had managed to greatly underestimate his friend’s “potential.” That wasn’t all, the krogan’s cock was almost human-like. It was covered in thick, almost rough looking foreskin that was long enough to cover the cockhead almost entirely, leaving just the very tip poking out. The plan was just to get a quick peek but Shepard couldn’t stop gawking.

His cock’s opening was so big, not being the vertical slit shape but more of a perfect hole and from it some precum began to leak out, slowly and lazily oozing out as Grunt began to sleepily hum in his sleep. The first thing that came to Shepard’s mind was how the alien’s precum taste but he quickly shook his head and figured that he had already gone beyond what he originally intended.

He was about to pull the pants up again but then the shaft started to twitch and elongate before his very eyes going from about twelve inches while flaccid and then twice as big as that, becoming a fully erect twenty-six inches. Everything about his cock became bigger all at once, from his fully engorged tip and flaring out into a mushroom cap shape all the way around being dark pink in color. The foreskin slid further back but remained just as thick. As it had become longer, the mighty thing also increased substantially when it came to girth, becoming fat and meaty the whole way through and then right in the middle of it all was a fat medial ring that made the foreskin rise and stretch around it.

“If you wanted to see it you could have just asked…”

Grunt’s voice made Shepard look up, seeing that the krogan was awake now. But he didn’t seem mad, in fact he was smirking. “And now that you’ve got it like this, it’s your responsibility to take care of it.”

“Quite the weapon you’ve got here,” Shepard said as he properly grasped the flexing monster with two hands. “Can’t blame a guy for wanting to inspect it.”

“And you can’t blame me for the damage it’ll do when it goes off,” Grunt said in retaliation, leaning back into the couch as he felt the human’s smooth hands starting to tug at his kroganhood. Like the rest of him, it was a product of the great krogans that made up his being. Just another thing about him that struck awe in others, krogan or otherwise.

The human’s hands wrapped themselves around the long and fat thing as best they could before giving a squeeze to really test the firmness. Feeling the touch skin and the way it was pulsing with strength against his touch compelled Shepard to get stroking right away.

Grunt reacted to this with a deep rumbling noise. It wasn’t much but it was already feeling good. He was entirely used to his own big and rough hands, not the smaller and smoother human’s. It made his length pulse and from his flared out tip came a wide trail of precum that ran downwards. When the line of heavy fluid reached Shepard’s hands, the human used it to his advantage, willingly getting them completely slathered with the stuff, smearing all over the cock it came from as he continued pumping.

That made the feeling even better for Grunt but he could also feel some restraint on Shepard’s end. And he was right. This was being done on purpose so he could feel up the mighty shaft for as long as he could. Grunt responded to this limited amount of pleasure by roughly thrusting against the hold.

“I need more than that!”

“So I figure,” Shepard said. Instead of picking things up, he removed his hands completely, leaving the shaft partially coated in viscous precum and throbbing. Of course this left Grunt feeling unfulfilled and he looked at the human with bewilderment.

“I think there’s only so much I can do with just my hands. Mind if I do a bit more?”

“Do whatever the hell you have to!” Grunt growled with a mix of need and irritation.

Given the permission he needed, Shepard’s hands were back on it, just barely able to fully wrap around. Before he actually resumed where he left off, the commander pulled the shaft downwards, just enough so that the tip was lined up with his mouth. He couldn’t deny that this wasn’t just for the sake of getting his friend off. This was also a fantasy that he was finally able to live out, a change that he wanted to make the most of.

A deep moan came from Grunt as the stroking continued, the pair of wet and warm hands going up and down, reaching even further this time. They ran over his fat medial ring and even further than that, stopping just behind his tip. That part was being directly stimulated by an even softer and wetter tongue.

The krogan felt pure pleasure racing through him and he had nothing to complain about. The hands weren’t weren’t just simply going along his length but also rubbing, squeezing, and twisting. Clearly Shepard was trying to feel him up as much as he could while doing this, admiring his raw virility, not that he could blame the human for his curiosity. Though he never considered something like this happening he wasn’t going to decline the chance.

While he was being stroked and licked, the huge alien found the remote and he turned on some entertainment, but not the kind that he had been watching before. This time he found some porn to let play in the background while he enjoyed himself. He had come across a few stations and this was the perfect chance to use them.

Having some visual stimulation on top of the physical feeling made Grunt moan out even more. With another pulse came another line of precum that spurt from the tip and with Shepard’s mouth being right there, the human willingly caught the dense and flavorful fluid with his tongue.

“Bold,” Grunt said.

His words weren’t responded to. Shepard was clearly dedicated in full to the task in front of him. The hands were still collecting precum and using it as lube. Now each pump was paired with a wet sound that was only getting more pronounced. The licks to the cockhead were becoming smoother and all the more pleasurable as Shepard had gotten a good feel for the wide, firm surface. It was discovered that the backside of the tip was particularly sensitive.

Licking in whatever way he could and keeping his hands moving in interesting ways, Shepard was keeping the pleasure constant but unique as well, keeping the krogan reacting to everything that was happening. Light tingles and strong buzzes were all given to him and he was loving the variety. Clearly Shepard was experienced in this field as well.

His feelings were evident by the amount of precum that he was letting loose. Even if he was a tankborn, his quads were fully functional and they were showing their prowess by keeping a flow going. Spilling from his perfectly circular urethra were fat gooey lines that were either being collected or smeared around by Shepard’s mouth and then his hands.

“Don’t forget about the quads,” Grunt said, pointing down to his huge and wide sack. He pulled the sweatpants down entirely and kicked them off, spreading his legs much further to give the smaller male full access. Of course, being given the chance to interact with a krogan’s quads was a chance that couldn’t be passed up, especially when he was presented with a pouch that was so big in every way.

The stroking was paused as Shepard used both hands to touch the ballsack. Starting out his touch was light and teasing, getting a feel for it. Like the rest of the krogan, the skin was rough to the touch but the sack itself was surprisingly pliable, able to be pinched and tugged. His hands roamed along with the underside and he could feel the protrusions of each ball, each one felt even bigger than it looked and they were all churning so hard that he could feel it through the thick skin.

A sound of satisfaction came from Grunt as he felt the hands roaming over his sack. He wondered if Shepard had actually done something with a krogan before but his ample exploration suggested otherwise.

Having his hands sliding along the bottom, the human was rubbing in circles that slowly expanded outwards, covering more area. Precum was still coating Shepard’s palm and fingers. It was being rubbed onto the skin, allowing smooth movements that were bringing an unexpected amount of pleasure to the larger male. Feeling those quads churning in real time served as motivation to keep Shepard rubbing and even gently squeezing.

Grunt continued watching the porn playing while also enjoying the massaging of his plump nuts. He continued to let out deep moans and grunts freely in reaction to the touching that just got better and better the longer it went on. Shepard’s slick hands were reaching further out, rubbing all over the quads, giving each individual sphere its due attention.

When Shepard returned his attention to the cock he found that the bottom side was completely coated in layers of pre that had leaked out. Playing with those balls had made even more come out. Shepard acted accordingly, using the extra amount of slippery and hot fluid to pump seamlessly up and down, running right over the medial ring, tugging the foreskin along as well from how firmly he was squeezing with both hands. When pulled up the long and thick skin was bunching itself against the back of the flared out cockhead.

“Y-you might want to...” Grunt snorted and growled as he felt all four of his balls drawing up, letting out a deep bellow as he felt himself being pushed over the edge. “Oh, n-nevermind! Brace yourself, battlemaster!”

He had tried to hold himself back and warn the human but the pleasure was just too great for him to endure any longer. He could feel the seed already flowing through his swelling cock and with his tip flaring expanding even more, being pointed right at the human’s face.

Huge jets of cum that were as thick as Shepard’s own thumb and as thick as honey erupted from the perfectly circular opening. Not one to shy away from a challenge, the commander took the blast head on, getting his forehead coated along with his hair. His hands continued pumping at the huge pole of flesh, milking out even more cum that was splattering heavily onto his face, painting a clinging layer over his nose, lips, and right between his eyes. He didn’t think much about what he was doing, overcome with pure lust and the need to see a krogan blowing his load up close. There was no fear of mess or disgust in being painted by another male’s jizz, just a drive to see climax in full and up close.

As one could imagine, having four balls all pumping at once brought an incredible amount of pleasure, making the krogan’s breathing hitch and his eyes were fluttering. With every throb and spill of his seed, his body was overcome by intense waves so strong that he was at the mercy of his own loins, watching as his length was being handled and aimed.

By this point the upper half of the human was coated in thick, hot, and gooey layers of krogan cum. Shepard kept himself kneeling in place, resigning himself to a collection post for the raw essence, using his body to catch rope after rope.

The next spray was more than enough to completely coat his face, making him blind for a moment before the heavy seed trickled downwards, rolling over his neck and then adding to the amount that was already soaking into his clothes, taking it all as Grunt continued expelling more and more of his rich slimy nut all over him.

Shepard wound up opening his mouth again as he moaned out as his face got marked again. He was given just a small taste of the fluid as it dripped downwards but the human was really hoping to get a full taste of what the alien and his quads had to offer. After all, there wasn’t anything to stop Grunt from doing it.

Grunt was too busy riding out the pleasure of such a big and long climax. It had actually been a while since his last ejaculation and he needed this more than he anticipated. He moaned out louder and his cum was being expelled with even greater force now. Every inch felt rock hard as it wildly pulsed against Shepard’s hands.

The pleasure was kept so incredibly intense by Shepard’s spermy hands still pumping away, his hands being absolutely coated in krogan cum. His cock’s opening swelled and a flow of cum came, blasting all over the man’s face. It painted his face in another thick and hot layer like a mask one would wear at the spa. And the seed just kept coming, spurting all over the rest of his face, getting even more into the human’s hair, all over his neck, and slathering his lips heavily.

At this point the commander’s face was coated to the point that his vision was completely blocked but he kept going, having his tongue out and finally collecting splashes of the rich stuff onto his taste buds. He was struck by how strong the taste was; wholly bitter but not off-putting.

Grunt was starting to feel lightheaded as his balls were still churning hard all at once and his cock was shooting out long and fat jets, all of it coming out and striking the human’s face, the excess sliding down to further mess up the clothes he was wearing.

After what seemed like ages, the endless ejaculations were starting to weaken in strength before they were becoming less frequent, the last of his release oozing from the wide opening. From his head down to his waist Shepard was completely slathered in the alien’s cum and everything behind him was given a layer as well.

With all that over, Shepard was left panting, his mouth still open and his tongue hanging out, having a thick mask of seed to keep his vision obscured.

“Told you not to blame me for the damage,” Grunt said with a sigh as he felt his cock softening. His cockhead was shrinking and the foreskin enveloped it again and the length as whole remained huge but wasn’t as substantial as before. “I ought to get cleaned up and it looks like you’ve got some cleaning to do too.” He stood up with his sweatpants still off and stretched before he began to head for the bathroom. “And we should make this a regular thing.”

Even after the mess and himself were eventually cleaned up, Shepard was still reeling from everything that had happened. He didn’t think it would be so intense. Grunt was in a much better mood for the remainder of their stay in the apartment as he was treated to a few more jerkings. But it came time for them to return to duty and Shepard was honestly nervous about how their dynamic would change on the ship.

Luckily Grunt kept things a secret, not acting any different but he was clearly expecting some things from Shepard and the human was reluctant to engage, much to the krogan’s growing frustrations. He could tell that Shepard wanted to do more as well but something frivolous was holding him back. So ultimately the krogan decided to advance things himself, going off on his own to get something that would serve to help them.

When he came back Grunt presented Shepard with his half of the device, promising that it would allow for them to have their fun in a discreet manner. Shepard wasn't sure how Grunt gifting him a set of ordinary looking underwear. But Grunt insisted that if he wears them he would eventually understand and even enjoy it.

The next day Grunt was pleased to find that Shepard was wearing the underwear, he could tell because on his end he had a special device that let him know when a pair was being worn but the main part that he was eager to test out was the special fleshlight. It cost a lot of credits to get one his size but he was sure that it would be worth it. Staying in his cabin on the ship while Shepard was out on a call, Grunt was laying back on a bed completely nude with his cock already hard and slathered in lube.

Shepard was just finishing up his call when he suddenly felt something poking against his ass. It made him jump a gasp just from the shock of it. He was sitting down in a chair and in the room all by himself and yet something rounded and wet was rubbing itself against his rim, making it wet and slippery as well.

Before he could even question it, something started to push its way inside of him. A deep grunt came from him, something was stretching his hole farther than it ever had been. It was hard, slick, and even leaking. He could feel warm fluid spurting inside of his ass, adding lube that came before another push that slid more of whatever it was inside. The start of it was particularly wide but the rest wasn’t much thinner and it was hard for him to keep his voice under control when the ache of being spread was paired with strong bursts of pleasure.

Grunt was growling pleasantly as he was pushing the fleshlight down on his dick, loving the tightness that was surrounding the portions that were disappearing past the opening. As it turned out the fleshlight and the underwear were to be used in tandem, connected with portal technology. The toy could be penetrated, made of soft material and lined with ridges but since it was turned on, Grunt was instead treated to the unmistakable feeling of an actual hole.

Looking down, Shepard could feel it reaching in deep and he saw the bulge forming in his lower half. As more and more inches were being pushed into him it was getting larger, making his ass stretch and rearranging his guts from the sheer size and force. He didn’t know that he was capable of taking it and from deeper inside of him Shepard could feel the precum being spurt, bringing a rush of heat that spread outwards. Now that the shock had worn off it wasn’t hard to figure out why this was happening. That gift from Grunt…

Grunt pushed all the way down to his medial ring that swelled firm just past the halfway point of his total length. It seemed that was Shepard’s limit for the time being and he decided to let the human have that given it was his first time taking his cock and it was through unexpected means. At least a good portion was being kept warm and wet.

”I’ll settle for now…”

He began to move the toy, lifting it up letting out a grunt from the silky walls that were rubbing themselves against his length. He could hear the sounds of his cock sliding from the snug hole. It remained so tight the whole time, much to Grunt’s delight. He stopped just short of letting the wide tip pop from the stretched him, instead pushing the toy back down and pushing it all the way back down to his medial ring.

Meanwhile Shepard was telling himself to take deep breaths and keep his voice steady. He was thankful that Grunt was at least going slowly for the time being but that didn’t do much for the girth that was spreading his ass full and making his stomach bulge when the tip was stuck in deep.

Still holding back, Grunt smoothly pumped his cock outwards then back in all the way down to the ring. While doing that, the precum was freely spilling from his cock, making the human’s ass all the better to hump into. From his perspective the bulky fleshlight appeared to be leaking as his own excess precum was oozing out.

Just when it felt like he was getting a handle on the incredible size another groan was forced out of him. Another thrust had come and it was stronger than the ones that came before. Shepard couldn’t see the krogan pushing down with greater force, forcing just a bit more of his cock into the toy, having the opening pressed firmly against his medial ring. With a snort and firm downwards push in time with a hard upwards thrust the thick engorged ring popped in and the force still being output caused the rest of his cock plunge in as well.

Shepard had been in the middle of responding to another call when he felt it and saw that his stomach was stretching much further in a much faster amount of time, bulging out obscenely with the wide cocktip’s shape being seen clearly even from underneath his clothes. He could feel it throbbing in the entirety of his anal passage and precum was being deposited directly into his stomach.

It felt good! Much better than he could have expected, with no pain at all despite his body being forced to make room for the iron-hard flesh that was both stuffing him with its girth and filling him with his length. He could feel his insides being stimulated in ways that he never felt before, bringing relentless waves that racked his body.

“Now we’re talking!”

Grunt firmly gripped the toy by its base, keeping it steady while he started to really move his hips, putting strength into his thrusts to ensure that every inch would be jammed back into the toy. Pushing in so deep that his weighty quads were smacking against the fleshlight, clinging lines of slimy precum were sticking to Grunt’s thighs and even more was gushing out as his cock forced to fluid out to make room for his cock diving in again.

“Is everything alright over there, Shepard?”

”Just fine. We’ve seemed to have come right into the past of oncoming asteroids,” the commander quickly lied.

”Damn things. Change course without cause or reason. Sometimes they just show up out of nowhere.”

”How about we put this on hold for now? This is something I should have my full focus on,” Shepard said, trying his damnedest to keep his tone even.

”Understood. We’ll discuss further in depth later. Good luck out there.” The call was ended and Shepard sighed before he allowed himself to moan aloud. He could feel the cock roughly pumping into him. His underwear and pants were soaked from the precum that was first being injected into him before spilling out. Every time it was pushed as far in as it could go.

Not far away, Grunt’s growls were becoming deeper as the pulses of his cock were becoming all the more pronounced, thrumming in time with his roaring heartbeat. He took a moment to pull back slowly, again making sure all but the tip was sliding from the toy. That was a feeling he couldn’t get enough of. Shepard’s ass was just getting wetter and warmer from his precum and those clenches never lost their intensity.

Their separation made actions unpredictable and Shepard was completely unprepared for the full powered slam that jammed everything back inside all at once. This made the human gasp and shake uncontrollably, his cock pulsing madly and shooting his load into the underwear. It was bleeding through and making a dark wet spot in his pants, a very noticeable one.

With the arrival of his climax, the tightening of his ass was even stronger. Grunt was at first surprised by this and then he chuckled and powered through the unrelenting constrictions, snorting deeply as he was still jamming the entirety of his maleness in as far as it would go.

This was just what Grunt needed to get off, struck with a climax that was even stronger than the ones he felt when being milked by Shepard’s hands. The girth of his shaft increased as the whole thing swelled.

Then it began spraying into Shepard with force and in heavy amounts right from the start. There was so much of it but instead of being released all over the human’s face or the floor it was all blasting right into Shepard’s guts, rushing around his cock and spraying out with more power than the precum had as well. All four of his fat balls were drawn up and pumping their own loads through his cock all at once and all of it was going into the human on the other side of the portal.

Shepard was already feeling a bit full from the amount of precum that had been dumped into his stomach, making it swell out even more than the hilted cock had. But that was nothing compared to the eruption and the increased expansion of his stomach, getting bigger in time with every fervent throb, making it bigger and bigger. He could feel that it wasn’t just his stomach but also his anal passage, flooding him full as the cum was firing out like the full strength beam from a high powered cannon. With Grunt keeping himself deep inside, there was nothing that Shepard could do but just watch and feel his stomach get bigger and heavier.

It was starting to become too much for him, a feeling of strain was building against the surprising amount of pleasure and comfort that came with being filled with so much cum. He didn’t know that his body was capable of handling so much but the question was if he could endure even more?

Luckily that question wouldn’t be answered today as the cock was then tugged from his stretched ass, the shaft and the flared tip as well, making a sloppy “pop” sound as it all completely retreated from his body. And with it out his body wasted no time in expelling the cum that filled it so thoroughly, heavily leaking and even pushing out the dense jizz, completely ruining his pants while the underwear were made for this kind of thing, still in perfect working function. As he pulled the toy from his cock, Grunt sighed and then raised his voice as gushes of cum from the human’s ass were shooting through the other end of the portal, splattering onto his crotch and thighs. He then chuckled and turned off the portal function, leaving Shepard to deal with the rest of the mess…

“You could have told me how it worked from the start,” Shepard said when he next ran into Grunt.

“Well you didn’t ask and I wasn’t sure that it was going to work either,” the krogan said with a shrug. “You’re clearly in one piece so you at least survived the ordeal. So the question is, did you enjoy it?”

“Grunt, you could have at least made your intentions known beforehand,” the human said.

“Well where’s the fun in that? Always knowing when it’s gonna happen. I thought you would appreciate the added thrill.”

“Grunt…”

“If it bothers you that much then just don’t wear the underwear anymore,” Grunt countered.

“Fine then. That will be all,” Shepard said before taking his leave.

Grunt didn’t make a big deal out of what happened. In fact he hung around in his room and just waited until the next day, waking up to find, much to his delight, that another pair of the portal underwear had been put on by Shepard.

“I knew you couldn’t resist.”

The krogan didn’t make use of this right away. Instead he decided to wait until the time was right. He went out and did his usual duties around the ship, even stopping to talk to Shepard. Both were acting as they usually did. Eventually the time for lunch came and Shepard joined the others in the mess hall but Grunt wasn’t there…

Back in his room, naked with his lubed cock at the ready, Grunt had the toy gripped in his hand with the portal function on. This time he sped right past the whole teasing portion and he pushed himself in, thrusting in right away, using the pumps of his strong hips to shove more of his inches not into the sleeve but into the hole on the other side of the portal.

Shepard’s eyes went wide. He was already sitting down and starting to eat when he suddenly felt himself being filled. At least this time it was easier thanks to the lube and his hole still being somewhat stretched from the last portal fucking. But that didn’t help much when Grunt was actively barreling his way into the human’s guts, even forcing his medial ring into the toy and past the rim on the first try, making Shepard take all of him from the start.

“How do you like that?” Grunt asked as he groaned, gripping the bedding with his other hand.

Shepard was keeping himself as steady as he could while having a huge cock literally throbbing in his guts. It pulled back but then thrust in again. Without a moment afforded for a proper adjustment, the cock was already going in and out at a brisk pace. Shepard had to actively fight to not shake or moan out as the girth was plugging his ass all over again. He thought he would be prepared but that was proved false in an instant.

Just as the thickness kept him feeling stuffed, the length was touching more than just the prostate, the even wider tip spearing its way further beyond. This made him clench down on reflex and this action earned him a firm throb. And then came the first gush of precum, the amount being just as substantial as the first time.

Being in the presence of others, Shepard had to keep up his appearance, even more than when he was on call. But the clenches of his ass just seemed to encourage Grunt to hump into him even harder. Of course that damn krogan wasn’t going to make this easy for him. Maybe this was the plan all along, to make it a challenge? Well if that’s the way he was going to play it.

Shepard got up and excused himself, using every bit of strength and poise he had to walk evenly despite the thrusts that were still going. At least until he was out of the others’ view. Then he quickly ran down the hall and found the nearest restroom, diving inside and locking the door. At about the same time he got his pants down and sat down on the toilet. He fished his cock out, letting it poke free from the underwear’s front opening. Keeping the special garment on, his ass was still being roughly reamed.

Grunt felt that something was different, there was a lot of movement on his end but it felt good. It was making his need all the stronger. Already his balls were feeling so full again, all four quads were hanging heavy but he had the means to drain them.

Precum was being spurt freely into the hole and the excess was spilling out just as it had before, soaking into the underwear. On the receiving end of it all, Shepard allowed himself to moan freely as he began to jerk himself with one hand. The other just rested on his stomach, feeling the shape of the cocktip becoming more pronounced when a thrust came.

Grunt just kept applying more power and speed, feeling himself getting close. He didn’t intend to last as long as he did the last time, going for the sheer rush and explosive pleasure that came from releasing directly inside of a hole. With another hard shove that buried the tip far inside along with his medial ring, slamming his cock all the way down to the base, Grunt let out a deep and long moan as he came.

All four of his huge balls were pumping huge amounts of seed through the pulsating rod. When it reached his flared tip the fluid was geysering out. Wracked with the blinding pleasure, Grunt managed to thrust a few more times while also spilling his hefty loads. He slammed back in and kept his cock like that, using his thickness to keep the hole plugged.

The repeated strikes to his prostate had brought Shepard’s to a climax as well. Thrumming in his hand, the human’s cock was shooting seed against the walls surrounding the toilet and onto the restroom’s flooring.

Just as he was shooting his loads, Shepard groaned as he felt the first rush of krogan cum. Heat was pouring into him as the extra sticky fluid was splattering all over his walls and then keeping itself plastered. His stomach was already starting to expand from the great amount of jizz that was being unloaded.

Expanding out further from more cum being released, Shepherd could do little more than shake and pant while the feeling just grew all the more intense. While his stomach was bloating the excess was already spilling out of him, getting this pair of underwear messy like the first pair had been. He had no choice but to just last through it all, feeling the continued throbs of the hard krogan meat.

Grunt’s cock was gushing like crazy, flooding the human’s passage with his thick and hot essence. Feeling his abdomen stretch all the further out to make room for so much cum was exhilarating and pleasurable in its own way. On the other side of the portal, Grunt was panting heavily, his chest rising and lowering as he rode out the incredible feeling.

Shepard was leaning against a stall as he panted deeply, feeling the strain of his body being pushed to its limits. He didn’t think he could handle anymore but the loads just kept coming as Grunt was still keeping his cock buried all the way down to the base, even having his quads pressed firmly to the toy’s casing.

Luckily the cock was finally pulled from his ass with a sudden and firm tug. A deep and wet slurp sound came as the whole thing was pulled from the stretched rim. Along with the cum that was leaking out right away, Shepard felt fat ropes of jizz being shot all over his hole, clashing with what was coming out. When it finally came to an end the both of them were panting separately, now basking in the heaviness of their afterglows.

Shepard was scheduled to have a checkup with Mordin. The salarian welcomed him to take a seat so he could start the physical. Everything was going as it usually did until Shepard grunted and shook.

“What’s this? A protrusion?” Mordin asked as he watched the bulge in the human’s stomach get bigger and then it suddenly shrunk. Jutting out and then disappearing, it first came as a shock but Mordin started to put the pieces together from the way it was rhythmically moving and from the underwear that Shepard was wearing. “I see. Krogans…”

Grunt was busy rutting into the toy at a wild pace, making low and heavy growls as he pushed himself in deeper and deeper. He had quickly grown to love this thing and was grateful to his commander for repeatedly wearing pairs of portal underwear. Even if he came off as annoyed it was obvious that he was enjoying it as well.

Then he felt something unexpected. While his cock was pushed all the way in there was something else providing added stimulation. He couldn’t see that Modin was working his hands on the shaft through Shepard’s stretched skin. Grunt didn’t know what it was but he wasn’t going to complain and instead bucked wildly, going even faster and spilling more precum into the snug hole.

His growls only got louder as the stroking and kneading was becoming better against his thrusts. Adding to the base pleasure of pumping into slick and squeezing tunnel, Grunt was compelled to put even more power into his rutting and he was pleased to find that the extra stimulation was becoming stronger in return.

This caused him to cum much sooner than he expected. Grunt roared out as he came and his cock was pulsing against the salarian’s touch, shooting all of its seed into the human’s stomach, making it swell all over again. The more this happened, the easier it was becoming for Shepard’s. He found that he could handle more stretching than before. Grunt eventually pulled out and Mordin removed his hands as well, leaving the human panting heavily.

With the cat out of the bag the two began to talk and Mordin had his beliefs confirmed. He agreed to keep it a secret but he was also very curious. And asked if Shepard could get Grunt to see him.

Grunt did so but only because of his commander’s word. He was expecting to be lectured about what he had been doing but instead Mordin wanted to run some tests. The krogan was apprehensive at first but eventually agreed when Mordin revealed that he wanted to test Grunt’s sexual prowess. As a created krogan he had potential that could possibly surpass his peers.

Liking the sound of that, Grunt agreed to these tests and was pleased to find many of them involved collecting samples and recording data when it came to his thrusting strength and the force of his ejaculations. Coming in day after day finally gave Shepard a break as Grunt was having too much fun getting milked by pumps and shoving his dick into perfectly warm and lubed mounts. But the fun didn’t last forever as Mordin got his needed results and used them to make something.

That something was injected into Grunt and at first nothing happened but after about 5 minutes he felt strange, doubling over as his body began to expand. While this was happening he was feeling no pain but rather a tingling pleasure. He was getting taller and wider, his shoulders, arms, and chest all gaining added bulk. Mordin was watching with interest as the krogan was being enhanced in every way. Now he was even bigger than any naturally born krogan but that wasn’t all.

As Grunt turned around to face the salarian the first thing that caught Mordin’s eyes was his cock and quads. The shaft was still gaining inches and added thickness, throbbing as it was becoming erect. He was already big at 26 inches, but thanks to the experiment he had gained 10 more. The sight of his cock was jaw-dropping all on its own but there were also his quads, each ball had gone from the size of an orange to that of a coconut and the sack was much wider but still fit comfortably thanks to the creature’s expanded gait. Just as he was done growing, Grunt snarled as he felt the burning heat of rut ripping through him.

“Where is Shepard?”

The toy wasn’t going to be enough this time. He rushed out and made a beeline for the commander’s quarters, all but breaking the door in and tackling the human to the bed. It all happened so fast, the human’s clothes being torn away and something hard and wet already pressing itself to his ass. With the krogan holding him firmly, Shepard just braced himself for what was to come, seeing that Grunt was clearly bigger and unfocused on anything more than taking care of his needs.

When the first thrust came, Shepard’s hole was quickly spread all over again but even further this time, making the human yell out as he was being penetrated by something even bigger. A simple push from Grunt was all it took, having even greater strength to make use of. The precum that was already being spilled from the tip in large amounts thanks to the expanded balls and Shepard’s ass was still a bit loose from the near daily poundings. Those factors worked together and so far about half of the cock was easing in without much trouble, their first roadblock being that medial ring that was even fatter all the way around.

That seemed to be enough for Grunt for the time being. He gripped Shepard’s body firmly and began to thrust. His pace was quick and hard right from the beginning, repeatedly bashing that medial ring against the human’s already spread and twitching rim. The spreading of his ass was even greater even if the whole thing wasn’t inside yet. Shepard was gasping and moaning while stuck underneath the much bigger male. His body and the bed were being rocked by the hard thrusts and then the hard slap of the heavy sack against his backside.

Being even bigger and fucking him so aggressively, Shepard was expecting to feel pain but instead he was feeling an intense pleasure that he wasn’t prepared to endure. One his stomach and feeling the krogan’s rough skin grinding against his back, the firm – almost crushing grip on his shoulders…

Whether it was a pull or push, every movement was sending waves through him. Even if just a bit more than half was in, that was still more inches than before and way beyond what was needed to touch his prostate along with various other spots that had been discovered thanks to previous rounds.

His hole was still trying to adjust to it all, still being stretched even further around the cock. The even fatter tip was certainly felt sweeping back and forth, bringing the most pleasure and the heaviest feelings that forced him to shake and release precum as well.

The pulses were so strong and in return the constricting of Shepard’s anal passage was stronger as well. The precum was flowing freely and even much larger amounts, already spilling out during thrusts. With the tunnel becoming all the hotter and slicker, Grunt didn’t pass up the chance to go even faster. In reaction to this, the human moaned out and gripped the sheets firmly in his balled hands.

Even though this felt good to him, Grunt still wasn’t content to have just about half of his cock inside. He wanted the whole thing to feel the added tightness and messiness that clung to the walls. So he rammed his whole body forwards with even greater force, pushing directly against the rim that was slowly starting to stretch it out even further, making Shepard cry out with greater volume.

Another yell was forced out of him as the medial ring was finally forced in. And with that portion past the ring of muscle, the rest of the cock barreled right in, sinking all the way down to the hilt, bringing back the bulge in Shepard’s stomach with a vengeance, now much bigger than before. His ass squeezed down harder than ever as the human’s body was shaking hard.

After getting the whole thing in, Grunt began to pull out, making the smaller male groan from his medial ring making its way back out, stretching the entryway yet again but from the opposite end this time.

While the krogan felt nothing but pleasure, his body boiling with the simple need to rut. When the ring had come free there was only a moment to process before it was jammed back in without mercy. This and the rest of the inches going in deep and with so much force behind it wrenched yet another forced moan from the commander.

Neither of them were talking, completely consumed by what they were feeling respectively. As best he could, Shepard kept himself stable against the hard filling and strong push that again rocked the bed. He was completely at the much bigger and lust-riddled alien’s mercy. And it was exhilarating.

So many of his sensitive spots were being bashed and rolled right over and his guts were repeatedly forced aside, ending with the even bigger shape of Grunt’s cocktip stretching his stomach out even further. His rim was forced to stretch even wider to allow the ring to either come out or slide in and each time it forced a reaction out of the other male. The movements would just happen at the krogan’s leisure but soon became faster, constantly being forced past the anal ring from either side. Shepard had no idea how he was still in one piece, being all but crushed under Grunt’s weight and on the receiving end of his full power thrusts.

Just a few more of these thrusts was all that Shepard could take. His ass was keeping itself incredibly tight around the length that was pistoning away, powering through any sort of squeeze with ease. When the medial ring was forced in again everything that came before it would suddenly jam in much further, touching those extra tender spots.

Unable to last against this any longer, shots of his cum were being released onto the bed. The heavy pleasure of blowing his load while still being penetrated by such a huge cock. It just became a blur for him.

The enhanced tightness from the human’s climax reached the krogan and he capitalized by humping much faster, his hips becoming nearly a blur as he jammed every inch in rapidly, tugging everything but the tip out and then using pure power to get everything back in at once, each of these rounds ending with his quads loudly crashing into Shepard’s ass.

When the final thrust came Grunt snorted and clenched his teeth, slamming in so hard that it made the human’s backside raise up some as his cock absolutely speared its way into the human’s perfectly tight and warm body. The medial ring was plunged in even further and Shepard certainly felt that. And then he felt the krogan’s ball sack churning and pulling up. Grunt’s whole body was shaking as he felt the rush of his climax and the intense throbs of his cock as cum was surging through it.

And then it was shot out with unrelenting force, washing the already precum-marked walls with new layers of almost boiling hot and tar-thick cum. It was quicker than ever to fill up the human’s ass and this time the medial ring was acting as a plug that would keep all of the fluid inside this time. So it was all rushing right into Shepard’s stomach as well.

As more and more cum was being fired off with full force, Shepard’s stomach was expanding further with every gush that came from the flared out tip. These loads were much larger than the ones that came before the growth. He was still completely at the krogan’s mercy, still stuck underneath and filled to the point that there was nothing he could do but just wait for the climax and fizzle out. And that didn’t happen for what felt like 3 minutes later, his stomach becoming so much bigger over that course of time, literally ballooning outwards. He had no idea how but Shepard’s body managed to handle it all, the whole load with no single drop being allowed to flow past the medial ring that was still fully engorged.

When things were finally easing up, Grunt sighed and took hold of the human’s hips, his touch being both firm yet gentle. A simple jerk back of his hips was all it took to pull the medial ring free, leaving his commander’s hole gaped and immediately leaking thick and extra sticky cum. It was a good thing that he was already against the bed as he would have collapsed right away anyways. He just panted and trembled as more cum was spilling out of him and onto the floor.

Shepard had needed a bit of time to recover from that whole ordeal and Grunt had enough restraint to leave him be, even when was notified of the human wearing the portal underwear.

“I wasn’t too hard on you, was I?” Grunt asked when they met in person again.

“All things considered I’ve been through worse.”

Hearing that made Grunt laugh and he roughly slapped Shepard on the back, making the human stumble. “Just as I thought! And besides you can blame Mordin for what happened. He apparently made the serum too strong.”

“So I can assume you’re back to normal?” Shepard asked as they started to walk together.

“As far as mental goes, yes. But I was never a normal krogan. Not then and not now either,” Grunt said. His heated rut state was gone but he was still much bigger in every way, now even more of a prime krogan stud than he had been before.

“And I’m gonna show you what it's like when I’m fully in control later on,” Grunt said in a lower tone before he broke away, walking ahead.

“Not just gonna spring it on me this time?” Shepard called with some amusement in his tone.

“The waiting will make it all the better when the time comes,” Grunt said with a chuckle before he rounded a corner.
