Mayumi, a mature Japanese wife, finds herself alone at home and decides to indulge in some self-love. She starts by gently caressing her body, her hands tracing the curves of her ample bosom and full hips. Her breath hitches as she slips her hand beneath her panties, feeling the wet heat of her pussy. She teases herself, her fingers dancing over her clit, before sliding them deep inside. Just as she's about to reach her peak, she hears the front door open. Her husband has come home early. Mayumi quickly covers herself, but her husband, with a wicked grin, tells her to continue. He watches, his cock hardening as she resumes her masturbation, her moans filling the room. He can't resist any longer and joins her, feeding his cock to her eager mouth.
