[Honryo Hanaru] Bokura Fuyou Mono (COMIC LO 2018-09) [LoliAce]

When his little sister Yuki climbs onto his bed whining that she doesn't want to go to school, her older brother trades a groggy morning of brutal classes for something far more intimate — coaxing her thighs apart and working his fingers into her until she's biting her shirt, twitching and soaked. What starts as lazy fingering and stolen kisses becomes her first time, her small body pinned beneath him as he mutters apologies between thrusts before gripping her waist to cum inside her. Beneath the heat runs a quietly melancholic thread of neglect and obsession, a brother who only truly touches his sister when it suits him, and a girl too lonely to refuse him.
