[Yabachorogi] Imouto wa Otonappoitte Iwaretairashii | My Little Sister Wants to Be Told That She's Grown-Up It Seems [LAYON]

A petite, pixie‑cut sister, flushed and trembling, confides that her once‑childlike form has blossomed into something unmistakably adult, begging to be told she’s grown. She finds herself drawn into a heated, consensual exchange with her older brother, whose towering presence and massive anatomy contrast with her delicate curves as she experiences wave after wave of pleasure. The narrative unfolds through intimate panels that highlight her expanding breasts, the tight grip of her bike shorts, and the relentless rhythm of their union, culminating in a climactic, multi‑orgasmic climax.
