DVEH-011 Sumire Kuramoto Got Horny To My Little Sister Who Unconsciously Seduced Me In A Room Wear That Was So Sloppy That Her Bristles Could Be Seen

An older brother who was supposed to be alone with a school girl's younger sister - Sumire. Taking advantage of her parents' absence, Sumire takes off her clothes and wanders around the house in loose loungewear. You can see her erect nipples with her no bra, and the bristles peek at her face from her shorts. My brother, who was lusting for such an unconscious temptation, devoured the body of the dozing Sumire, and even remembered jealousy to go out on her date, until she forced her mouth. What is the answer my sister gave to my brother who can't be honest with himself?
