Sweetie's ass gets the 'A' grade treatment today. Her stepdad's been waiting, hard and eager. He watches her stretch, her gym shorts accentuating her big ass. He can't resist, spanking her, making her yelp. She turns, eyes wide, but he's already on his knees, burying his face in her pussy. She grinds against him, then it's his turn. He slides his thick cock into her tight ass, slow and steady, letting her adjust. He fucks her hard, her moans echoing in the empty house. She clenches around him, loving the feel of his cock in her ass. He pulls out, stroking until he cums all over her back, marking her as his.
