"Hey, Kyle!"
Kyle looked over his shoulder to see one of those damn lugheads approaching him. A former boyfriend of Jen's actually. Mark wasn't known for his brain, rather his prowess in bed. Kyle couldn't help but notice Mark's bulge, and muscles. He'd envied him for so long. But not anymore...
"You seen Jen nerd?" Mark asked.
"Who?"
"My ex dumbass. No one's seen her all morning. And I've got a problem that needs fixing." Mark said, looking pointedly at his junk.
"Oh, sorry Mark. Maybe she's in the bathroom." Kyle said, trying not to laugh. Mark looked at the girls' bathroom, and then back at Kyle.
"You're mental man. I'm not going to barge into the girls' toilet!"
"Why not?"
"Dude, what the fuck kinda pervert are you?"
"You're looking for an ex girlfriend so you two can fuck during school. And you're calling me a pervert? Besides, girls go in the girls room." Kyle snickered.
Mark was about to say something when he doubled over in pain. His insides felt bloated, and his body broke out into a sweat.
"What the hell?" Mark said.
Kyle watched as Mark's hair grew out, longer and longer. Cascading into foot long waves of brown hair. His face lost its hard lines, and softened. The stubble on his chin and jaw disappeared, and his lips enlarged. His thick brow thinned, and his nose became rather delicate. His thick man hands slowly shrunk, and lost all hair on them.
Kyle disappeared Mark's, now more like Mary, clothing so he could really enjoy the transformation. His donkey cock was stiff, and his pants had a wet spot from the pre. Kyle's eyes were fixated on Mark's chest. His chest expanded, growing outwards until he had B cup breasts. Then they gained form, and swelled. His nipples grew thicker and longer, and his areola became the size of half dollars. His hips grew, as did his ass. Both started to gain womanly curves, remaining tight but still increasing in size.
Mark's penis slowly shrunk, but it didn't disappear completely. It was left at about four inches soft, with balls the size of eggs in his sack. Behind his scrotum, a slit had formed. Mark/Mary moaned as the slit grew deeper and deeper, and a hole formed inside it. Soon, the slit puffed out, forming her labia majora. Inside another layer of skin grew out, the labia minora, and the hole started to drip fluids onto the floor. Mark now has a hairless pussy, G cup breasts, and a tight ass. His entire body is still begging for a release, though Jen wouldn't be able to give it to him/her anymore. He needs a cock to fill him up.
Kyle looks on as Mary the shemale lies on the floor fingering her new pussy, and stroking her micro penis. Kyle pulls his pants down, and bends over her. His donkey dick dangles in Mary's face. She opens her eyes and sees this animalistic cock above her. Mary stops what she's doing to engulf as much of Kyle's shaft as she can.
Her hands rub Kyle's penis, and massage her new breasts. Kyle pulls out of her mouth, and motions for her to turn around. Mary does, pressing her ass into the air so Kyle can gain access to her new cunt. Kyle obliges, and slides his dick into her folds. She screams as the head of his cock touches her virginity.
"Ready?" Kyle whispers.
"Yes! Please, fuck me Kyle! Take me, take my virginity!" Mary screamed, rubbing her penis faster. Kyle breaks the hymen in one swift thrust. Mary cries out in pain and pleasure, a small amount of blood leaking out of her vagina. Kyle starts pumping in and out. It's not as good as the animal sex he had with the donkeys, but it did the trick. Mary on the other hand was loving every minute of the sex. Being taken by a huge animal penis, it was incredible. Her penis swayed, her balls pulling up and then she came in both sexes. Thick ropes of cum landed between her breasts. And her pussy gushed, as she achieved her first female orgasm.
Kyle's spunk overflowed out of Mary' cunt. She dipped her fingers into it, and savored the taste. Once again, Kyle pulled his pants back up once his cock had deflated and returned to its furry home. He left Mary lying in the hallway, and continued in search for more victims.
