Yes

You have had enough of this, you may be Sarah's boyfriend but your not some simple fuck toy.

as your teeth come down (not enough to break skin) she scream, using this time as she is holding her now going limp dick you manage to pull your pants up while you escape, once your home your mum asks "What's wrong?" you meagerly answer "Some girls were trying to get with me, they did not take my answer well" you then head to the bathroom and have a shower, using the showerhead to clean your gaping ass out.

The next day at school, fuck....you forgot she was blackmailing you. as you walk past a group of girls the 'leader' pulls your pants down exposing your fat yet still slightly agape ass.

The teasing goes on for the day, you don't even see Sarah, is she okay? as your classes end and your heading home, your heart drops, she is there next to what you assume is her car, deciding to try and ignore her you try to walk past as she stops you "Look, sweetie, I'm sorry.... I did not mean to **** you to take me.....Sarah is at home.....she is going to discuss an agreement on both ends...hop in"
