In the dim light of the attic, a brother and sister find themselves alone, their parents away for the weekend. Boredom turns to tension as they watch each other, their bodies stirring with unspoken desires. The sister, dressed in a thin tank top and shorts, can't hide her hardening nipples, while the brother's sweatpants tent with his growing erection. Their eyes meet, and the sister, emboldened, reaches down, rubbing her pussy through her shorts. The brother watches, his cock throbbing, as she pulls down her shorts, revealing her bare, wet slit. He can't resist any longer, pushing her down onto the old couch and burying his face in her pussy, licking and sucking until she's writhing with pleasure. He then positions himself between her legs, his thick cock sliding into her tight, welcoming cunt.
