In a family role-play scenario, Riley Reid takes on the part of Melissa Moore's step-sister. They share a secret, forbidden passion, their eyes meeting over the dinner table, their hands brushing as they pass the salt. Later, they sneak into Melissa's room, their hearts pounding. Riley traces Melissa's tattoos with her tongue, moving down to her pussy. Melissa gasps, her fingers tangling in Riley's hair. They switch places, Melissa's tongue exploring Riley's tight, shaved cunt, their moans filling the room. They trib each other, their bodies rubbing, their clits grinding together, until they both cry out in ecstasy.
