An older sister and a younger sister who usually don't know each other's sexual circumstances. However, the sisters who live under one roof are in the prime of puberty. Even if you know you have a family, you can't suppress your naughty desires. One day, such sisters face each other's sexuality due to trivial events. Two people who are shy but come out about their sexuality to each other. From there, the excitement gradually increases, and even though there is a sister (younger sister) in front of you, you feel intensely with each other. As the pleasure increases, the distance between the mind and the body gets closer, and before you know it, the sisters are in a close relationship. The two who feel each other at zero distance further increase their excitement with each other's skin texture and breathing, reaching climax many times. I wonder if the end will come to the two people who have met each other many times.
