[Hiraya Nobori] Natsu Loli Ism [Decensored]

During the heat of summer, a bespectacled older woman draws a school-age girl into a sexual “training” game that begins with awkward teasing and becomes increasingly coercive. Their bedroom encounters expand into masturbation and a broader group dynamic, contrasting the girl’s embarrassment and curiosity with the woman’s unsettling control. Dialogue identifies her as Rina and gives the ritual a strange “vacuum” motif, lending the taboo premise a memorable identity.
