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 sister (Tara Ashley). She takes a few sips and low-and-behold, his potion works! His sister 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 brother 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 brother�s dick. Craving cock in her pussy, she climbs on top and fucks him. Donnie plows his now-slut-of-a-sister from behind. As he rubs her pussy, she lets out a loud queef. Tara lies on her back a let�s her brother fuck her hard until he cums and shoots a load of jizz into her mouth.
