Sarah Lace, the reverend's daughter, sneaks into the adult store, driven by curiosity and a desperate need to learn about sex. She's caught red-handed by Rusty Nails, the burly security guard, who catches her red-handed with stolen porn. Instead of calling the cops, he offers her a lesson she won't forget. He forces her down onto her knees, making her deepthroat his massive cock until she gags. Then, he bends her over the counter, ripping off her panties, and pounds her tight, wet pussy with hard, rough strokes, teaching her the true meaning of sin.
