[Circle Cherry Boy (Erai)] Gal Band no Imouto wa Kuzu Aniki no Ne-Back ni Cho~ Yowai

An older brother forces his shy, weak-willed sister into degrading, incestuous acts, her ahegao expression and swollen, bared buttocks dominating each panel. The story escalates from aggressive commands to intimate, wet contact, with the brother’s relentless dominance and the sister’s helpless surrender creating a tense, erotic atmosphere. A raw, 39‑page manga that blends explicit blowjob, masturbation, and nakadashi scenes with a stark, monochrome art style, delivering a provocative tale of familial betrayal.
