Ryan had been aware the whole time that his owner, Jason, had been cold clocked by his stepbrother. That had not done him much good while he could not see what was going on, but soon enough Jack had stripped his victim and stuffed Ryan into his mouth. Along with binding him to the table this had taken quite some time and much to his dismay he had felt himself start to transform while still in Jason's mouth. Up to the point where he'd finally been pulled out and tossed on the floor he had been resisting the change as hard as he could to avert the potential catastrophe if he swelled up to full human size while in Jason's mouth.
Then, finally, he was able to relax and let the transformation overtake him. He'd been thinking about what he would need to do to save them both. He'd be slippery from spit and naked, but he'd have the element of surprise. He'd need to incapacitate Jack quickly, hopefully he might already have his pants around his ankles, but even if not he'd need to do a low blow and then follow it up quickly with punches to his head.
Ryan staggered to his feet and found that "the Jack Hammer" had seen the movement of him growing to his full human size and though shocked by what he just seen he was ready for the teen. Ryan tried to knee him in the crotch but Jack's fist made a good contact with the side of his head and then he was crashing to the floor as another well practiced blow knocked him cold.
Ryan awoke hogtied using duct tape on the floor. He was on his side and he easily recognized that Snake's tattooed dick with its ampallang piercing was in front of his face.
"Good, you're awake too now." Jack's deep and cruel voice continued to make clear his plan, "I don't know how you got inside, but I figure since you were naked you're one of the guys that likes to polish Jace's knob. I think, for once, one of you pansies ought to get a little something in return from him, don't you? So you're going to suck each other's dick for my entertainment."
There didn't seem to be anything to say to that or any way out of doing it. Ryan knew that he'd soon start to change into a jockstrap again after sucking Snake's cock and he dreaded to think what might happen to him then. Still woozy from the two blows that had knocked him out he inched forward to put his lips to the snake while Snake did the same to his crotch. For a while nothing happened since neither of the boys were in the mood, but several days without ejaculation meant that soon Ryan's cock was leaking precum and soon after Snake's was doing the same. Then things got weird.
Ryan was sure he was transforming and his bonds were getting loose, but he could something was happening to Snake as well. Snake's eyes were wild with fear as everything seemed to pull in, their bodies merging, arms and legs twisting out of shape, and the bonds that held them falling away. Their bodies darkened and extremities merged to became hollow legs and a waist band as their heads and bodies shrunk into the crotch thighs and rear. Soon there was nothing on the floor but pair of jeans made of black leather with a green snake embroidered on its pouched crotch and curling around one leg. Thought the garment did not move at all as it sat on the floor to the two 18-year-olds who made its substance it felt as thought they were both still sucking the other's penis.
Slightly fazed by what had just happened Jack said to the empty room, "Well that was something." Then he grinned wickedly because of a vile idea. He stripped off his pants and put the new lined leather pants, the garment magically stretching and conforming to his body. "Just my size, looks like you and you're friend's asses is going to be mine for even longer than I planned."
