[Yami Books (Yami)] My Younger Brother is Sexually Curious!? [noaicicle]

Puberty hits Yosuke hard, and he blurts out to his older sister that he wants to do it with her, leaving her frozen over her coffee until his wounded pout dissolves her protests that siblings shouldn't. Her soft, heavy chest and warm hands end up guiding her nervous little brother through a messy facial and a breathless first ride, both of them drenched in nervous sweat as she takes the lead on top. Sweetly awkward from confession to afterglow, it's a trembling portrait of sibling affection slipping past the point of no return.
