Donnie (Donnie Rock), a young amateur chemist, needs a guinea pig on which to test his latest concoction. He believes he has created a potion that will turn normal everyday girls into raging sluts. So, he spikes the ice tea and offers a glass to his virgin stepsister (Tara Ashley). She takes a few sips and low-and-behold, his potion works! His stepsister becomes super horny. She can’t control herself and rubs-one-out. Ramming her pussy with her fingers, she brings herself to climax. That’s when she notices her stepbrother peeking from behind the door. She commands him to “come over here!” and commences to give him a deep, sloppy blowjob. She enjoys gagging on her stepbrother’s dick. Craving cock in her pussy, she climbs on top and fucks him. Donnie plows his now-slut-of-a-stepsister from behind. As he rubs her pussy, she lets out a loud queef. Tara lies on her back a let’s her stepbrother fuck her hard until he cums and shoots a load of jizz into her mouth.
