A young wife's trip with her husband should have been a happy time, but he says he's tired and goes to bed early. Feeling lonely, she changes into a yukata and heads to the massage parlor he had reserved. Shy and unable to refuse since her husband is asleep, she agrees to the treatment. The massage oil makes the towel slip off easily, accidentally exposing her big breasts. From there, things spiral out of control. Filled with thrill at the thought of her husband waking up if she makes a sound, she ends up experiencing unexpected bareback penetration. Her big tits bouncing, she desperately tries to suppress her moans. Without her consent, he cums inside her, and overwhelmed by the intense pleasure, she can't resist. Her pure feelings and her relationship with her husband take an unexpected turn.
