In their cozy marital haven, a wife and husband decide to spice up their love life. She lies on her back, legs spread, as he kneels between them, her asshole glistening with lube. He teases her, rubbing his cockhead against her tight ring, making her squirm. He pushes in, gradually stretching her, letting her feel every inch of his thick shaft. He starts to fuck her, slow and steady, then builds up speed, pounding her ass, his balls slapping against her pussy. She loves the feel of his cock in her ass, the taboo sensation of being fucked in a way she never has before. She comes hard, her ass clenching around him, milking his cock as he fills her with his hot cum.
