Rubber Cock, Giant Cock for Sunkit by Draconicon

Landon blushed as he felt the otter's paw stroke up and down his cock. It was so different, but so much better than when he had been human. His cock was at least five times more sensitive than it used to be, and he swore that the latex covering it added at least a couple of inches to his overall size. Then again, that might have been part of the overall transformation he'd gotten, going from human to a latex version of Panther Caroso, sort of like what had happened with his twin as Logan had transformed into a rubber version of Leon from the same video game.

The two of them were kneeling on the bed, getting their cocks stroked by their otter benefactor, David. Occasionally, Landon looked down at him, but most of the time he just panted as he was stroked and teased by the otter's expert hands. They were surprisingly good at what they were doing, and he swore that he'd been on the edge of orgasm for at least the last half hour.

"Mmmph...please...let me cum!"

"Ah ah, Landon. Just a bit longer now, and then you'll cum."

"You said that ten minutes ago!"

"Well, I'm saying it again. Just a bit -"

But Landon couldn't take it any more. He groaned, thrusting his hips forward and fucking the otter's hand. Even though David took his hand away, it was too late, and he came hard. Squirting thick, black-tinted cum from his new cock, he soaked the hotel bed with his goo, leaving it stained and darkened.

Both David and Logan glared at him for his lack of control, and Landon blushed as he came down from the orgasmic high.

"Sorry. You know I don't have much self control."

"Well, you'll have to learn it," David said. "And not just for sex, considering what we'll have to do out in the world."

Landon slowly nodded, looking down in embarrassment. They were supposed to be helping David with things, or would be when they finally left the hotel. So far, they'd just been part of a general debauchery that was going on for a couple of days now. He was starting to wonder if David actually had a plan for things, or if he was getting stuck in a rut of enjoying his powers.

Either way, though, he was right. He needed to learn self control, to live up to the new body he was in, if nothing else.

The otter had already turned back to Logan, though, and was teasingly stroking the rubber chameleon's erection with a chuckle.

"You know, I think this could be a lot bigger."

"Uh, well, you were the one that changed me. Do you want to change me, um, again?"

"Heh, I don't have to. You're rubber, remember? You can grow as much as you like with a bit of inflation."

That idea sent a little color to Landon's cheeks. He'd always been the 'bigger' of the two of them, down there, and that continued in their new forms. The idea of having his twin getting bigger than him after all these years was a little...embarrassing, to say the least. But he wondered if it was possible.

Well, he already knew that some inflation was possible. After all, Logan's feet had been the first thing to grow after the transformation, just so that their new benefactor could enjoy them and play with them. Sadly, they hadn't really looked so much like feet during that. The swelling from the air had made them huge, but also distorted the rubber shape. It'd turned them into a ball-tube from the heel to the toes, and the toes themselves were barely more than smaller balls attached to the larger, central one.

Considering how that inflation had gone, he didn't know how it would go for his brother's cock. It would probably look a bit silly, particularly if it got all that much bigger than it was right now.

Still, Logan looked interested, and Landon didn't want to stand in the way of what his brother and David wanted to do.

"Can I help?"

"Actually, yes," David said. "Go around behind him; we'll need to get some extra air in."

As Landon did as he was told, Logan blinked and got on all fours.

"I thought that I could grow it like I did my feet. You know, suck in air, and think it -"

"That could work, but it didn't make it look very nice. The way that Landon is going to help you will keep your cock looking, well, like a cock."

Which I think all of us would prefer, Landon thought as he got behind his brother. The rubber ass was just as good as he had always remembered it being, though his twin's ass was a little bit tighter looking. He chuckled; probably one of the few advantages of getting a new form, sexually.

"So, what do I do?"

"I'm guessing you brothers have rimmed each other before, right?"

Both of them nodded.

"Well, what we're doing now is similar. Except instead of tongue-fucking your brother, Landon, you're going to start puffing air up his ass. Later, we'll try this with a pump, but we don't have one of those right now, so blowing by mouth is all we got."

Landon could hardly imagine that working, but it was all that he had to go on. Shrugging, he leaned forward - getting a small glimpse of his brother's 7 inch cock in the process - and pressed his lips to that rubber hole. It felt a bit like an inverted blow-tube that one could find on a raft or an inner-tube. Experimenting, he flicked it with his tongue a few times, sucking in -

"AH!"

His brother's yelp nearly distracted him from the sudden pop of something slipping into his mouth. As he rolled it between his lips, he realized that there was a blow-flap back there. It just had been pressed inwards.

Who knew? He pressed his fingers into his brother's ass cheeks as he started to blow. That lovely mirror that had allowed him and Logan to witness their own transformations was still nearby, so he could see the erection between his brother's legs still out of the corner of his eyes. He kept watching it as he breathed in through his nose and breathed out through his mouth.

It didn't take long for Logan's cock to pop out from between his legs, the artificial veins running along the exterior of the shaft popping outwards and getting bigger as the shaft started to expand. Landon grinned around the blow-tube, and kept puffing, reaching down and wrapping his hand around the shaft as it continued to grow.

Bit by bit, it started to expand in his grip, growing thicker as it grew longer. Rapidly passing eight, nine, even ten inches, it pushed past the limits of his grip in seconds, soon too big for one hand to wrap around. Landon blushed as he realized that he was being left in the dust by his formerly smaller twin in terms of cock size. A glance in the mirror showed it stretching out even further, making the chameleon look a bit more like a horse, considering his cock was already thudding against his chest.

"Ooooh, Landon...that feels...weird..."

He pulled back, putting his thumb over his brother's ass to keep the air from getting out.

"Good weird?"

"Oh hell yeah..."

"Heh, good."

He lowered his mouth to the hole again, flicking his tongue over the end and letting the air escape a little bit. Every time that he licked it, his brother gasped as though Landon's tongue was flicking over his cock head, and the air escaping showed an obvious shrinkage in the chameleon's cock. Less than a second of air escaping made it shrink down by an inch, and Landon chuckled at the sight.

Of course, he knew that it was supposed to get bigger, so he kept pushing air back in, huffing and puffing to keep inflating his brother's cock. Logan was moaning like crazy, and that inflated cock was oozing some sort of pre. It was similarly tainted, like his, but he didn't know just how it was changed. It just looked weird. Stretchy, more solid than his.

Finally, Logan's cock was so big that it was bumping his chin, and considering the loud squeaks that filled the air when Landon ran his hand over the surface of it, he was a bit afraid of adding anymore air. He pulled his head back from the hole, used his thumb to pop the tube back inside, and stepped back.

"I think that's enough."

"Awww, but Landon -"

"I think you're gonna pop if you get much more. I don't think you want to be a null, do you?"

"...No."

Landon nodded, but no sooner had the two brothers stood up than David was pushing them together again. Landon landed on his back, while Logan was resting above him, that massive package of an inflate-a-cock rubbing between their chests. Looking around his brother, Landon raised an eyebrow at the otter.

"Hey, just because you finished blowing him up doesn't mean that you're finished making him blow. I think it's your turn to submit to your brother for change."

"Wha - with that monster?!"

"Hey, you're latex. You can take it."

"...Right."

He slapped his forehead. He'd forgotten about that. Landon slowly spread his legs, exposing his sheath and ass, and watched with more than a little trepidation as his brother lowered himself down. That cock tip had gone from being a small mouthful to being as big as his fist in terms of width. What if he wasn't as stretchy as the otter thought? What if Logan was a bit too eager and did something he shouldn't? What if -

And then the shaft slid in. His hole, so loosened as latex, took it easily, and all Landon could do was moan as he was filled to the brim instantly...and yet there was still over two feet of cock for him to take.

"Ooooh fuck..."

"Heh, happily, bro."
