Adult college-student role-play. Kokoro drinks heavily at her college club party while her junior Takeshi keeps her company. He passes out and misses the last train, so she offers him a place in her room. On the way home she learns he is a virgin, and her pent-up desire leads her to seduce him. Although he cums quickly, his incredible stamina turns the tables and leaves her cumming again and again throughout their two-day weekend.
