[Hamaguchi Mitama] Hoshizaki Touko ga Wakaranai (Comic Kaien VOL.12 ) [EroGPx]

Hoshizaki Touko is the weird, enigmatic girl in class whose heart-jolting physical intimacy completely flusters her earnest, glasses-wearing classmate. What begins as awkward study help weighed down by his guilty confession about an ulterior motive melts when the soft, busty twintailed schoolgirl gives her consent, admits her body feels hot, and pulls him into breathless, consensual closeness filled with flushed breast play and urgent, slap-heavy passion. Between her cheerful promise to get an even higher score next time and his lingering thought that he still doesn't quite understand her, their flirty tutoring romance teases whether more honest, hands-on lessons will finally unravel her mystery.
