Oni no Sumu Ie

Oni no Sumu Ie follows a young protagonist who travels to his grandmother's rural home for the summer holidays, anticipating a quiet and uneventful break. However, what begins as a simple seasonal visit quickly takes an unexpected turn when he finds himself drawn into a series of intimate encounters. The familiar setting of his grandmother's house becomes the backdrop for a surprisingly passionate experience, as flirtation and physical affection soon define his time there. As the summer progresses, the boundaries between a relaxing vacation and a deeply personal romantic entanglement blur entirely. The narrative focuses on the protagonist's shifting dynamic within this secluded domestic space, where playful teasing gradually escalates into far more intense moments of connection. Stripped of everyday distractions, the story explores how a routine family visit can transform into something wholly unforeseen, driven by desire and close proximity. This mature manga was originally distributed across three separate installments at major doujin events. The first part debuted at Comiket 91, followed by the second installment at Comiket 93, with the third and final part released at Comiket 95.
