“So what are you doing for the weekend,” Asked a student as he walked into the bathroom clearly on his phone, “ya I’m gonna head up to the lake house this weekend.” the student saddled up the urinal that Sam had just used and unzipped their pants. As the boy pulled his member out the smell of Sam's human and tainted spunk hit his nostrils. “Ya hold on, let me call you back. There's something really rank here.”
The student doesn't notice Sam in the stall as his changes begin again. His mouth is the next site to change as it morphs to suit a more lewd purpose. Sam’s tongue is forced out of his mouth as it starts to grow in length, gaining enough length to wander around the tip of his pointed cock sticking out from his pants. Eagerly he gives the tip a lick, this creates a wave of pleasure across Sam’s body. His new changed cock now much more sensitive than he is used to made him shoot a gob of musky semen onto the tip of his tongue.
Tasting his newly changed spunk ignites something in Sam as he feels himself become more and more corrupted. He felt a need deep inside himself to corrupt others for his own jokes. This was the demonic stamps doing as it gained more control of Sam as he was giving into his urges.
From the voice Sam heard he knew that the person that was in the bathroom right now was Kyle, one of the popular kids in the class. Kyle was a douche and every one knew it, he was always mean to Sam and would be the center of attention from the girls. Sam undid his pants and took off his shirt to see his changes, he wanted to have the full shock factor for Kyle as he went full troll mode.
Sam hollered from the stall, “hey Kyle I bet I can give you an ass beating right now loser sucks the others cock.”
“Who the hell, never mind you better be ready for an ass whooping you fag,” shouts the kid, “where you at!”
“Right behind you” Sam replies as he opens the stall door to show off his naked body, his skin is pale white which makes his member stick out even more. His elongated tongue is jerking his cock as he squirts tainted sperm from his swollen balls. In a flash he whips the tip of his tongue with his musky gift into the Kyles open yelling mouth.
“You son of a bi... “, he can't finish his words as he feels the long range French kiss from his demonic classmate.
“How about we make you more useful as a good cocksucker.” Sam said in a more demonic tone than his normal voice. “God what is happening to me,” Sam thinks, “why am I doing this do I really want to make him suck my dick.” as he snaps out of the stamp's control for a moment the student rips the tongue out of his mouth.
“I need to get out of here,” panics the kid, “what is wrong with you, I can't get this taste out of my mouth.” the student runs over to the sink and starts to gulp water with his hands. He looks up and sees his face start to bubble. All over his face is pushing and pulling into a warped facia. His chin pushes out and his cheeks expand. He blinks his eyes as they wash over with black leaving him with soulless eyes. “What is happening to me, I look like a freak.” the boy moans as his body is racked with a wave of pleasure. He looks down and sees his cock harden against his blue jeans. His hands busy undoing his fly as he throws his head back and moans as his face continues to change. A large throbbing cock exposed now throbs in front of the boy. His now morphing hands grip the rock hard shaft as he gives in to his pleasure.
While the changing student was absorbed over his changes Sam walks over and turns Kyle around, “how's about we skip the foreplay and go straight to the fun part,” with a demonic grin as Sam shoves Kyle's face down to crotch level.
