Promise Ring

"Nice promise ring."
"Thanks. My dad bought it for me."
It was third period inside a small classroom. The brown walls seemed to suffocate any light rays that managed to fight through the dust covered blinds. Posters of Edgar Allen Poe and Maya Angelou hung on the walls.
Demi always found pure enjoyment of making Cory, the class virgin, squirm.
"So do you really plan to wait, or is that just to make him happy?"
"I don't believe in premarital sex."
"Aye then."
A sharp glance from the menopausal professor caused everyone to assume working positions once again.
Demi leaned over and whispered into Cory's ear, "So are you allowed to masturbate wearing it? Or is it against the oath, too?"
"Ugh!" she grunted while standing up from her adjoined desk, "May I go to the bathroom?"
Renee finally looked up away from her notebook. Cory's outburst had startled her, "What did you do to her this time?"
"I asked her if the promise ring omitted masturbation. What the hell have you been doing? You sit right behind us, you should have been able to hear it all."
"I was working on my project. You know, like we're supposed to."
