Mia, already feeling naughty from her parents' absence, finds herself face-to-face with Marco's massive hard-on. He convinces her to try anal, promising it'll feel amazing. Mia, trusting, lubes up and bends over, her big ass ready. Marco pushes in slowly, Mia gasping but eager. He starts slow, letting her adjust, then picks up speed, fucking her tight ass hard. Mia's moans fill the room, her pussy leaking onto the floor. Just as they're about to cum together, they hear their parents returning, forcing them to quickly clean up and pretend nothing happened.
