Her cousin caught her masturbating
Your body requires you to get rid of fluids that you have inside your body and the obvious thing is to go to a place where modern civilization says you have to go to do those things. But this kid finds his cousin there doing other things. She is very surprised when her cousin caught her masturbating in the toilet. Then she has no choice but to start giving him a cock suck so he doesn’t give her away. After he is ready to participate in the slut, then they start fucking and finally her pussy begins to have the pleasure that she wanted from the beginning.
