Billie participates in a sex experiment at the university

Billie is on her way to university when she is stopped to participate in a sex experiment. After giving her some money, he takes her to a nearby woodland and forces her to give him a blow job in exchange for a thorough anal fuck. Billie is given a thorough vaginal invasion when the postures are switched. Billie and the guy are both screaming in delight at the immeasurable pleasure.
