Dexter was cooing with delight as he edged himself closer and closer to an orgasm. "Almost there!" He commented. The soft fabric you had become was warming up in his hand from the friction as well as the throbbing cock itself. When he finally couldn't hold it anymore he did what he normally did just out of habit. Moaning blissfully Dexter closed his eyes and turned over to lay on his side as his hot, sticky seed shot out of his tip and made a huge wet spot on his new pair of boxers. As Dexter was panting and trying take a breather you could feel his cum seeping inbetween the threads of your new body as his wiggling sperm swimmed aimlessly around inside it.
Taking a deep inhale and smelling the distinctive pheromones that arose from Dexter's cum Hiram was temped to play along. Dexter was facing the wall as he was laying on his side, and this allowed Hiram to sneak up on his roommate. Getting into bed with him Hiram forced Dexter to lay completely flat on his stomach as he layed ontop of him. "Hey what are you- Ah!" Dexter groaned shortly before being interrupted by the feeling of Hiram's hips pressing against his rear end. Hiram had his sheath pressed firmly against Dexter's hole, with the boxers inbetween them, and in one smooth motion the already hardened satyr cock had emerged from his hairy sheath to plummet itself directly into Dexter's anus, taking you with it.
As you covered and followed the satyr's cock into Dexter's stinky, dark hole the rest of your form was pulled tightly around Dexter's hips and thighs causing the rapidly cooled wet spot to outline Dexter's large cock and balls. Hiram continued to thrust back and forth into Dexter's tight hole until he was approaching an orgasm himself. Giving no warning, other then a slight chuckle, Hiram used some of his own magic to change both you and Dexter. "Who comes around, goes around" He said. You felt your body tingle as your form changed. You suddenly felt less hollow and instead felt full, hard and warm as if a liquid was pumping through you constantly. There was no longer a person infront of Hiram or in the room with him at all. Instead it was only Hiram laying on Dexter's bed stroking himself with a condom on.
Due to the sudden change there was no longer any darkness surrounding you, but instead it was replaced with a blinding light thanks to your vision having to adjust. You still felt the pressure of something constricting your new form, and just now noticed your vision was drastically more blurry. When Hiram came that was the final clue to tell you what had happened. You felt the hot cum bubble up what felt like your throat and as it spewed out of your mouth it quickly coated your new form as it was caught by the condom. Hiram had turned you into his unique cock and made Dexter his custom fitted condom. Without even taking Dexter off Hiram retracted you back into his sheath. Your soften new body was squeezed as his sheath held you in for whenever Hiram was ready to use you two next.
