[Namaribou Nayonayo] Atsui Natsu, Oba no Ie de... ~Fundoshi Iwai~ (Web Comic Toutetsu Vol.30) [ChoriScans] [Decensored]

Jun arrives alone at his aunt Ritsuko's house on a sweltering summer afternoon, where the married woman's casual warmth and barely-covered curves immediately fluster the young visitor. When she slips into a traditional fundoshi, her teasing maternal facade crumbles—the aunt who once called him 'mommy's boy' finds herself undone by a stamina her husband never offered, her composed exterior shattering into begging and body betrayals she cannot control. A humid, sweat-soaked descent of a housewife discovering exactly how thoroughly her nephew can ruin her.
