"You mean, besides the entire class?"
"You know what I mean, silly."
"Oh. Ohhhhh." Jon smacked himself. He stood up and grabbed the two collars from his bag. "I'll be right back. Don't go anywhere."
Jon bolted down the stairs. There were lots of girls in various states of dress and undress, and they all seemed as tired as Jon. But when he offered the collar to one of the Four girls who turned him into a mermaid that day, she jumped at the chance. Her name was Jamie. She was Hispanic, just barely 5 feet, and had about C cup breasts.
He and Jamie sat down and put the collars on. They each passed out for a second and woke up in each others bodies. Jamie immediately jumped on Jon, drowning him in a deep kiss.
Jon was just barely able to push her off. "Wait wait. Why don't you go make those other girls happy? I have someone waiting for me upstairs."
Jon's body gave him a knowing smile, but ran off anyways.
Jon sauntered up the stairs and found Evangeline completely naked on his couch.
She sat up. "Jamie?" She saw the collar. "Ohhhhh."
"Ready for some fun?" Jon asked.
That day, Jon was turned into a woman 3 times, turned into a mermaid, got head from an entire class, and had sex with a hermaphrodite. As he fell asleep in Evangline's arms, her erect penis still in his vagina, he couldn't help but laugh that today was just the first day of school.
