Hatsukoi Time. – Episode 4 (RAW)

Enter the thrilling academic rivalry turned steamy romance in Hatsukoi Jikan #4 OVA, based on Saimon's masterful pure-love manga! Sadahito always finishes second in exams to the school's top genius, Kirin—a brilliant, teasing girl who can't resist sabotaging his study efforts with naughty distractions. Determined to beat her one day, he grinds harder, but her playful interference escalates: under-the-table teasing, oral temptations when he gets aroused, and even showing up at his house completely naked to push boundaries further.

Unable to resist her relentless ecchi antics, Sadahito gives in—their bodies connect in passionate, consensual first-time sex that quickly becomes addictive. With each intimate encounter, their competitive tension melts into genuine affection, hearts linking deeper through loving caresses, intense climaxes, and tender confessions. This episode captures vanilla hentai magic: study distraction play, genius vs. hard worker dynamic, rivals-to-lovers trope, teasing foreplay, and wholesome youth romance where sex strengthens emotional ties. Ideal for fans of pure love stories, academic rivals, naughty study sessions, and sweet, mutual passion that turns competition into unbreakable connection!
