Hot bangang with strangers in club, I'm a substitute sex slave

My classmate asked me to join a group sex club to earn some allowance few days ago, I say no to her. But she asked me to deal with a emergency case, she cannot go to that club even she already received compensating fee of be a one-day sex slave in club.  Finally, she  threaten me to tell my parents about affairs between my prof. and me. So I agree with her suggestion in the end.

Because they paid a great deal of money to my classmate, they treated me with no mercy by fucking my like a sex doll. The sex club members about 20, they keep banging me in a row. it's a very hard job to serve so many horny men and satisfy them  in a day.

Basically, my idea is simple, men will let me go if they all as exhausted as a dog. So I tried to please them by using every part of my body, my pussy,mouth, asshole, hair,feet,hands.....almost all of me. They all feel so exciting with my idea, we have a crazy day. Although I feel so grossing when blowjob a huge dick cumming in my ass right away, my idea was finally let me escape that place next day. A few days later, I receive a email which attached my revolting sex photos. They will invite me to be their regular sex slave member, I refused it by no reason.
