[Asagi Ryuu] Onee-san ga Iyashite Ageru Ch.1-6 [biribiri]

Married women on the edge of temptation answer messages they know they shouldn't, trading shy confessions with university students who make their hearts race again. Across six chapters, restless wives—including forty-year-old Kotani Chika and a woman who vows to be her young lover's for two whole days—slip away from ordinary life into borrowed rooms and stolen afternoons. Asagi Ryuu draws each affair with aching tenderness, from nervous first kisses to the moment each older woman finally lets her young man finish deep inside.
