[Kinomoto Anzu] A Little Sister's warmth (Chiisai hou ga Ecchi desho) [Team Rabu2]

Risa has a habit of sneaking into her big brother's bed every morning, and this time he decides to do more than grumble — his hands wander across her tiny, soft body while she sleeps soundly beside him. She wakes up mid-act, naked and furious, but with Grandpa and their parents just down the hall, staying quiet becomes part of the game as he insists her half-asleep self gave him the go-ahead. Her protests melt into shivers and kisses as her first time builds toward a clamping, mind-blanking finish she swears she never asked for.
