Kcup actress Yuzuki Marin finally allows anal! The dorm mother Marina felt pain in her ass, so she applied some treatment ointment given to her by a student… As time passed, her anus became hot and started to throb. It turned out that the medicine was actually an aphrodisiac cream that the student had mistakenly given to Marina. Her sensitivity skyrocketed, and Marina became addicted to the anal pleasure. Even though she knew it was wrong, just fingering herself wasn't enough, so she demanded dicks and toys from the students!
