"Cacete!" exclaims the sister as she watches her friend stroke her own thick cock, the sight making her hungry for a taste. She takes it in her mouth, gagging slightly at first but soon finding a rhythm, her head bobbing up and down as she sucks him off. Her friend, meanwhile, can't keep her hands off the sister's round ass, squeezing and spreading her cheeks, her fingers teasing her tight hole. The sister moans around the cock in her mouth, the vibrations making her friend's eyes roll back in pleasure. They switch places, the sister now on her back, her friend's mouth eagerly devouring her pussy, her tongue flicking against her clit, making her arch her back and cry out in pleasure.
