[Hayake] Onii-chan is Hopeless! (COMIC LO 2023-07) {Mistvern} [Decensored]

Karen loves to brag to her classmate about her hopeless onii-chan, but behind her cheerful boasting lies a taboo intimacy that blossoms the moment she comes home to find him. Her petite yet voluptuous body with huge, soft oppai and sensitive inverted nipples drives her older brother wild, pulling him from sucking and a devoted paizuri into a deep defloration of his little sister's tight pussy. Guilt and forbidden desire collide as he becomes obsessed with her swaying breasts and sweet, erotic reactions, claiming her over and over — and just when he thinks it's over, her friend's innocent request to meet him the next day promises the secret won't stay hidden.
