A raw, intimate portrayal of an affair between a slender married woman and an overweight man, highlighting their striking physical contrast and intense desire. Yui, a married woman in her third year of marriage, lies embraced on her lover's futon. Surrounded by the softness of his ample belly, he hesitantly asks for money, to which she smiles, pulls out bills from her wallet, and replies, "I'm always thankful..." before handing it over. His crotch moves close to her face, and she sniffs his scent. Engaging in 69 and blowjob, she takes his erect cock in hand, whispering shyly, "I want sex... I'm embarrassed (laughing)," unable to suppress her arousal. Mounting his condom-covered cock in cowgirl position, she rides up and down, moving as if escaping reality, surrendering completely to pleasure. A delicate, realistic depiction of infidelity, blending the strange allure of body contrast with complex emotional tension.
