Sayaha and her art teacher boyfriend, who is in a relationship, meet after school for a drive date! They start having sex with a condom at the love hotel, but she begs to have unprotected sex because she wants to merge quickly. The teacher, though confused, experiences unprotected sex for the first time and ejaculates inside her vagina! Afterwards, they have bubble bath sex in the bathtub, mutual masturbation while dressed up in costumes, and pre-farewell car sex where they look into each other's eyes while having five rounds of unprotected vaginal intercourse!
