[Asagi Ryu] Turning Pure White (Watashito Iikoto Shiyo?) [Nishimaru]

Mizue, a curvy woman in her thirties with big breasts and a habit of closing down the izakaya, keeps a devoted young student named Motohiko walking her home—and straight into her bed. Between hurried trysts among library bookshelves and sweaty nights tangled under a shared blanket, she sends him out for condoms and parts her hairy thighs for his eager mouth, all while quietly wondering whether a man so much younger will stay by her side. What starts as closing-time company deepens into something tender, because he understands every flaw she carries, and that is exactly what keeps pulling them back together.
