She has other ideas.

Suddenly, she kicks you away, forcing you onto your back. She drops down onto you with her knee, pinning you in place. You feel something cold clasp onto your cock, and before you know what's happening she lets you go. You look down at yourself and see your throbbing dick, locked inside a metal cage. "A chastity cage. Now I have you so **** to cum, I'm sure you'll do whatever it takes to get that off. If you can manage a top grade in your end of year test, I'll let you out. Being horny all the time might make it hard to focus on your work instead of me, but I'm sure you'll manage it. and if you don't I'll enjoy keeping you as my pet." She lets out a cruel laugh. "Now get out of here, you've got some studying to do" She commands.

You're stunned. You fell right into her trap, and now she has your dick locked up until the final exam, which is six weeks away! You pull your pants up and head home, knowing that if she wants, she could keep you as her **** forever.
