After working late, the two miss the last train and, in their panic, are suddenly caught in a sudden downpour. Rushing to find shelter, they end up at the female senior's apartment. As they dry their wet bodies with towels, the senior removes her blazer, revealing a soaked blouse underneath—sending him into instant arousal. Overcome with desire, he pins her down, groping her breasts as she gazes back with a dazed, seductive expression. Whispering "cute" under his breath, he locks lips with her, surrendering completely to passion. Following his instincts, he strips her clothes and moves toward her wet pussy. As he thrusts his rock-hard cock inside, she protests with a "No, no!" yet moans sweetly, welcoming him. Reaching his limit, he cums hard with a massive creampie. Realizing there's no turning back, he spends the rest of the night apologizing—yet stays until morning. An intense, erotic night with his senior begins like a full-course feast.
