In the confines of their home, a brother and sister, both horny and restless, turn to self-pleasure for release. The sister, fingers wet and eager, strokes her pussy while her brother, cock hard and throbbing, jerks off in his room. Their mutual masturbation is interrupted when they catch each other in the act, leading to a heated argument. But soon, they're drawn back together, the sister fantasizing about her brother's thick cock filling her tight cunt.
