Inkou Kyoushi no Saimin Seikatsu Shidouroku – Episode 1 (ES)

Megumi Fujimiya is the school's adored "onapet idol," a busty, innocent JK in the prime of youth, freshly in love with her childhood friend and baseball star Takashi Katayama. Her happy days shatter when the sleazy life guidance teacher, Mitsurou Fukama, approaches her with his special "Sex Life Guidance Notebook." Showing her the notebook, he alters her cognition so she genuinely believes that students with partners must undergo compulsory "sexual activity instruction" to graduate properly. Shocked at "forgetting" such an important rule, the apologetic Megumi agrees to remedial lessons in the infirmary. Under the notebook's hypnotic influence, she unquestioningly follows orders: lifting her skirt, exposing her panties, allowing intimate inspections of her developing body, and ultimately submitting to bareback penetration. The teacher thrusts relentlessly, filling her womb with "genetic fluid" as part of the fabricated curriculum, all while she remains convinced it's essential education. Her pure romance with Takashi is overshadowed by this secret, mind-bending corruption, leaving her body marked and mind rewritten in ecstasy and shame.
