I'm a hikikomori and I have a younger sister. She's an athletic girl who plays tennis, so I've heard. It had been a while since I last saw my sister. When we met again, she had grown quite a bit and developed large breasts. I love my sister very much. I adored her newly grown large breasts. My sister accepted my penis with a face of ecstasy. To get even more aroused, I asked her teachers at school to rape her in front of me. Watching my sister climax repeatedly with a face of ecstasy, I masturbated many times.
