EBOD-725 While their parents are not in the blankets with the titties... they're caught in a slow, direct sexual intercourse.

After their father's remarriage, two step-brothers were hot, and one day they were sleeping in a room with their sisters and flowers, and my sister Yua, and I couldn't control my sexuality, getting into their bed rubbed skins, which they refused at first, but they were clearly excited by the fact that they kept kissing and caressing their breasts, and slow caressing allowed us to breathe in a state of discomfort, and finally crossed the line to have silent sex in order not to expose the sound of penetration.
