[Poncocchan] Fellangle (Yarashii Kibun ni Naru Appli Ane to Ore to Imouto to) [Black Grimoires]

Kanami regularly thanks her brother Nozomu with her mouth, so when he sets up a webcam and asks to film one of their sessions, her nervous reluctance gives way to an eager performance. What begins as a recorded deepthroat—complete with gagging, teary eyes, and a face left dripping like 'a complete masterpiece'—escalates once he spreads her legs in front of the lens and pounds her toward a messy nakadashi finale. By the end it's the little sister herself begging to upgrade to a proper camera so they can shoot a real sex tape next time.
