Tired of the usual friendship banter, a curious sister invites her friend over, eager for something more. As they chat, she subtly teases him, rubbing his leg, whispering naughty suggestions. He takes the hint, pushing her onto all fours, her ass high in the air. He slaps and grips her cheeks, then drives into her, fucking her hard and deep in doggystyle. She moans, loving every thrust, her pussy dripping with lust.
