"You really can't resist, can you?" chuckled Rudy cranking away at the instrument while walking the short distance to his house just 3 down from the Tollivers.
"N-no. I-I can't" said Tony as he ambled along, dancing an energetic monkey jig to the music Rudy was playing.
Rudy pondered the possibilities as he led mesmerized Tony up the walk to the front door of his house. At a glance, Rudy could tell that his parents weren't home. Fan-fucking-tastic. Rudy started getting a hard-on just thinking of what he could do.
Rudy was one of clique of guys on both the soccer team and the drama club at school who were all bi. Well, maybe the effeminate goalie was just gay but the other half dozen had enjoyed each other's company and that of the stray girl here and there. Rudy had dated a girl in the drama club for half a year before breaking up. He was perfectly open to appreciating a fine round ass whether it was male or female. Somewhere within that incredible gorilla costume was the greatest ass in the whole school, Tony St. Martin. Rudy had masturbated to thoughts of Tony, that naked wet body standing right beside him in the locker room laughing with other boys. Ahhhhhh.
Even more incredible, Tony St. Martin was completely cool about it. Rudy had tested him once in the school library, telling Tony that he'd just overheard two boys saying they thought Tony was completely hot. Tony just shrugged and rolled his eyes. He never asked who they were or got mad. He never acted arrogant, as though it was proof of his striking looks. He was completely cool about it. But Tony was with Claire. Of that there could be no doubt, till now.
Rudy led Tony the 475 pound gorilla up to his bedroom and set the hurdy gurdy to keep playing. It took a minute of hard cranking to build up enough reserve power to last for a while but Rudy was up to it. He laid the instrument on the dresser and turned to Tony dancing in place.
"Stop dancing now" he commanded and Tony obeyed, standing at attention in front of Rudy's bed. He pawed Tony's huge ape body looking for a seam of some sort. But everywhere he pressed, there was nothing but hair and warm flesh beneath. He tried to pull the top off the costume but was similarly frustrated. He just ended up tugging at Tony's head and pulling hair.
"God damn! What's the trick to this suit? Tell me the answer, Tony"
"There is no suit" mumbled Tony without emotion.
"What? How can there be no suit?"
"There is no suit because I'm a gorilla"
"Are you kidding? Is that just what you're supposed to believe or something?"
"No. I truly am a gorilla. I am a simian primate weighing 475 pounds. I was transformed into this shape by Jeff's chronivac."
"What? What the hell's a chronivac?"
Tony launched into a 5 minute monotone description of the chronivac.
"So, this-this machine can turn you into animals and people?"
"Yes"
"Could it turn you back into your real body?"
"Yes, easily"
"But you wouldn't obey me in your real body, would you?"
"No. Not unless my auditory system was kept in this simian form"
Rudy perked up.
"Where can we get this chronivac thing?"
"It's high up in a tree outside the park where I hid it for Jeff so that no one could take it away"
With that, Rudy immediately led Tony out of the house and over to the park with the organ grinder music playing all the while. Tony leaped up into a tree and climbed up to a triple branch offshoot where the chronivac and emitter rested. He retrieved it and brought it back down and handed it to Rudy.
Rudy hustled back to his house, with Tony ahead of him dancing merrily to the music. With just a bit of instruction, Tony showed Rudy how to work the machine and how to transform him back to his real body but still entranced by the sound of the organ grinder music. As commanded by Rudy, naked 6'1" 167 pound Tony lay down on Rudy's bed and offered his rear end for Rudy's enjoyment. Rudy greedily jumped atop Tony and slammed his organ up the split of that luscious behind eliciting a whimper from Tony. Rudy didn't last very long the first time. But by his fourth orgasm inside Tony, Rudy had mastered the art of sodomizing Tony St. Martin.
The organ grinder music almost stopped once. That would have been disastrous, as 140 pound Rudy would have gotten the crap beat out of him by a righteously angry Tony. But Rudy was clever in how he played it. He asked Tony some more questions about using the chronivac and got the explanation about TransDem watching out for registered profiles. He also realized that Tony's brother and friends would be leaving the party soon and would do anything to get the chronivac back. So, Rudy just turned Tony back to his normal self after getting his clothes for him outside, with a bit of a push toward seeing Rudy as a friend, and made Tony forget about what had transpired. Maybe at some future time, Rudy would go for the chronivac. But better to play it safe for the moment.
