She playfully teases him, asking if he's thinking of his girlfriend. Marco admits he's not, fueling Mia's curiosity. She suggests they watch something more exciting, leading them to a private room. Mia strips, revealing her curvy body, and Marco can't resist her allure. He takes her from behind, doggystyle, as Mia moans softly, ensuring they don't wake their sleeping parents. Marco's thick cock fills Mia, their bodies slapping together as they chase their forbidden pleasure.
