[Punching Namatamago] Dekkai Imouto wa Itsumo Okotteru

An angry little sister, fed up with her lazy brother who refuses to get out of bed, storms into his room and threatens to wake him by any means, even if it means squeezing his massive breasts or biting his cock while he sleeps. She berates him for ignoring her feelings, accusing him of being a pervert who hides behind a phone, and vows to make him feel her frustration, repeatedly shouting his name and demanding he wake up. The brother, half‑asleep and defensive, tries to ignore her, but her relentless, provocative assault—pressuring his chest, threatening to bite, and demanding he surrender to her desire—creates a volatile mix of sibling rivalry, sexual tension, and forced intimacy.
