Ikumonogakari The Animation – Episode 1 (ES)

In a Japan facing catastrophic population decline, the "Ikumonogakari Law" makes sexual intercourse mandatory to combat low birth rates. High school students are paired up for practical sex education classes, learning proper techniques through real partner experiences. At first, the lessons follow a curriculum with teacher guidance, but the young, inexperienced boys and girls quickly become overwhelmed by excitement. Innocent curiosity turns into raw passion as they ignore rules, escalating from partnered practice to spontaneous group sex. Horny teens engage in relentless creampie sessions, blowjobs, titfucks, and full-on orgies right in the classroom. Hormones rage unchecked, transforming structured lessons into chaotic, cum-filled free-for-alls driven purely by lust. Adapted from the hit doujinshi by Marukorondo, Ikumonogakari The Animation Upper Volume captures the wild debauchery of mandatory sex class gone extreme—raw, uncensored hentai with nonstop school orgy action, internal cumshots, and teens losing all inhibitions in their quest to "fulfill national duty." Perfect for fans of group sex hentai, school setting erotica, and mandatory breeding themes.
