Tyler's head change had actually distracted him from his arousal long enough for his penis to soften and even start going back a little ways into his sheath. That was all changing as he stood here waving his new trunk around. He knew exactly what he wanted to do with it, but he had to wait until Madame gave the okay.
"Okay, Tyler, show us what your wonderful new parts can do! It's time for you to have some more fun."
It was disgusting, demeaning, and patronizing for him to talk to him this way, after turning him into ... THIS. It was a massive overreaction, in Tyler's opinion, to a few idiot comments he made while part of the audience. The show must go on, though, and Tyler knew he wasn't going to be able to resist.
His big black cock was at its full length and starting to stiffen, and Tyler wrapped his trunk around it near the end and lifted the thing up a little closer where both of his tentacles could easily wrap themselves around it. He tuned everything else out and just started humping into the firm, sensitive grip of his own three appendages. He could feel his own breath on his erect penis, and his tentacles especially were blowing his mind. They weren't bound by the limitations of human arm joints, and they could wrap a tremendous portion of their suction-cup-lined length all the way around his thick shaft, and there was plenty enough shaft to make full use of that ability. Nearly his entire two-foot boner was cocooned in a mixture of slimy octopus skin and rough elephant hide. Before long, the wide flat tip of his penis flared out and churning sensation bubbled up deep in his crotch. Tyler's froze up and tightened his three-way grip. The coil of tentacles around his cock tensed up and felt the first massive wad of bull semen gushing through its inhuman length. He watched it erupt through the trumpet-shaped cock-head while the next one surged up from the base. He felt every burst of semen in through his cock, his arms and even his dexterous nose. He completely lost himself in the pleasure rocketing up his crotch and tingling in his suction cups.
When the orgasm finally subside and his dick started to soften, Tyler was left shivering in the aftershocks of an orgasm no human could have had. It completely outshone every sexual experience in his short young adult life. He looked around at the messy product of his self-indulgent escapade: enough to impregnate a whole herd of livestock! Only livestock though. His bull balls would never bring him a human child, even if any woman would fall in love with him in this new form. They sure would bring him a lot of enjoyment, however, if this was any indication.
"Well, there you have it, folks. From a 19-year old sexy beast to a chimeric SEX BEAST. Let's hear it for Tyler!"
Tyler burned with shame that he had done this in front of an entire paying audience. He knew he was going to do it again fairly soon, though, whether anyone was watching or not.
