21-year-old college student Mai, who has a cheating boyfriend, decides to have some fun of her own after discovering his infidelity. She joins an overnight trip with a handsome male actor. Their destination is Karuizawa, the snow capital of Japan. They enjoy snowboarding and sledding at the ski resort, sightseeing at a winter waterfall, and secretly share kisses under the glowing winter illuminations. Back at the hotel, they play a game where each activity earns them a card, granting them the chance to have creampie sex. Initially shy, Mai gradually gives in as she begins to enjoy the pleasure, willingly accepting creampie after creampie. As the night deepens and they're alone together, she actively seeks out his cock, eagerly asking for round two. During this winter getaway, their bond grows stronger, forming a new, intimate connection.
