[Tamabi] The Philosophy of Intimacy (COMIC Anthurium 2022-09) [Nisor]

When their teacher gleefully announces a pregnancy to the class, two practical-minded classmates find themselves actually discussing the mechanics of sex on the walk home—a chat that ends with a condom run and an empty house. Hayase, a blunt tomboy with toned legs and a no-nonsense attitude, invites her buzzcut friend over expecting a simple transaction, but naked fumbling, eager fingering, and a first clumsy French kiss turn it into something neither planned. Two virgins discovering they are in the exact same boat, trading awkward confessions between touches, as careful preparation melts into genuine first love.
