He fucks his cousin when he catches him masturbating

Many girls, if they find their cousin masturbating, will probably run away or scream. But this whore is so out that what he does is kneel in front of him and put his cock in his mouth to suck. When her cousin tells him she is about to come, her aunt, instead of letting him do what she does, gets on top and starts walking, because what he wants is for him to release all the semen inside. They are in the bathroom of their cousin's parents' house and need to fuck fast because there is a risk of getting caught.
