[Fumihiko] Borderless (Otaku ni Yasashii Gal toka, Kyonyuu no Osananajimi toka.) [Kinsei Translations] [Decensored]

Titled "Borderless" by Fumihiko, the story opens as a bespectacled uncle returns home to find his ponytailed niece, Chika, anxiously waiting; her relief quickly turns to dread when he reveals he's aware of her secret and insists, "we have to take care of ourselves." What follows is a relentless escalation of violation—groping her swollen, heaving breasts until she's slick with sweat, choking her into submission, and ultimately pinning her over the table for a raw, pounding assault as she tearfully begs him to stop. The final frame captures her broken, flushed face, making it clear there are no remaining boundaries between uncle and niece.
