[Hashida Mamoru] Older Sister's Fragrance (Shiritsu Inwai Gakuen) [YxTL]

A boy's secret habit of stealing his sister's scent straight from her lingerie drawer backfires when she catches him red-handed and declares his punishment: masturbating right in front of her. What begins as a humiliating demand quickly spirals out of her control, as teasing fingers and bare skin pressed together give way to her riding her little brother until neither of them can stop their hips. By the time he's cumming inside her, the punishment game has melted into something neither sibling expected — a tender, blushing confession that maybe they've both been waiting for.
