We had agreed to have sex after the exams... but my girlfriend was given an aphrodisiac by a teacher with a lolicon complex, becoming sweaty, aroused, and extremely lewd. While I was buried in my studies, she spent her days with an "ah-hee" face, indulging in intense physical intercourse and ejaculation inside me. (Hinata Yuna DVAJ-745)

"We'll have sex after I get into my dream school..." Yuna is enjoying her innocent love with her boyfriend, whom she's just started dating. To preserve her virginity until after her exams, she lives a life of abstinence and diligence... However, a perverted teacher, eyeing this young student couple, forces the unsuspecting Yuna to drink an aphrodisiac, awakening her still-immature, childlike body. While Yuna's body remembers the pleasure, her emotions are the opposite; she repeatedly rolls her eyes back and crosses them during intense orgasms. This NTR sex, which destroys their pure youthful romance, allows Yuna to experience sexual pleasure before her boyfriend. Unaware that her boyfriend is engrossed in his studies, she is gradually being trained by the teacher into a sensitive and wanton sex toy...!
