Ryan had been aware the whole time that his owner, Jason, had been out from being knocked cold 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. 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 still 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 just as "the Jack Hammer" was getting starting to thrust his cock into Jason's unprotected ass and the teen screamed in anger and a little pain. The older man with the scraggly beard had not noticed the jock reshaping itself on the floor and so was stunned for a moment by the sight of a naked blond teen staggering to his feet. He managed to say, "What the shit?..," and stagger backwards before Ryan was on him trying to knee him in the crotch.
Ryan was lucky and the blow went home as he slipped on the dirty linoleum floor, both of them going down in a struggling heap. Ryan grunted in pain as weakened blows hit him and he tried to get in his planned sharp punches to the man's head. His knuckles were bloody before he changed tactic and desperately choked him until Jack finally went limp his bearded face slack and beet red. The whole fight had all taken two maybe three minutes at the most, but had seemed much longer.
Soon "the Jack Hammer" was bound with the same roll of duct tape that had been used to bind Jason and the intended victim had been carefully unbound with a paring knife.
Sporting his own nasty looking bruise on the side of his face he said to his Jock, Ryan, with intended dark humor, "You look great man." Ryan had many darkening bruises on his sides and arms not to mention the scrapes on his hand. He paused and said with genuine appreciation, "Good job."
Then they both looked down at the wiry dark haired man on the floor who might start to come 'round at any minute.
Ryan spoke the relevant question of the moment, "Goddamn, what do we do now?"
