Beva, the rebellious stepbrother, takes a liking to his new stepsister, Evelyn. He loves watching her change into her skimpy outfits, her perky tits and round ass driving him wild. One day, he catches her masturbating in the bathroom, her fingers deep in her wet pussy. Evelyn, embarrassed but turned on, doesn't stop. Beva joins her, his thick cock in his hand. He jerks off, fantasizing about fucking her tight little hole, while Evelyn watches, biting her lip, wishing it was his cock inside her. Their taboo desires grow with each secret encounter, until they can't hold back any longer.
