JUMP-4042 My sister is an obedient sex slave ● ♯3. Azuki Ogura Azuki

Azuki, a kind-hearted adolescent girl, has an older brother. I have more feelings for my brother than my brother and sister for some time, but I’m always worried about my brother who is messing around in the house without getting a regular job. One day, my brother takes a voyeur of Azuki’s foolery with his senior’s wisdom, shows the image and threatens to dominate his sister so as to cut through his innocent heart.
