[Chinese]REAL-824 My sister ran away from home and stayed at my cramped apartment. When I found out she had a boyfriend, I went mad with jealousy and kept ejaculating inside her. Tenma Yui.

My sister ran away from home after fighting with our mother. The cause of the fight was her new boyfriend… I let her stay for the night, holding complex feelings. She changed clothes in front of me without a care, leaving me at a loss for where to look. We ended up sharing a futon. I couldn't help but notice, and I was inwardly troubled… Just the other day, I still thought of my sister as a child. The swelling fantasies and jealousy towards her boyfriend who could do whatever he wanted with her body became uncontrollable, and I lost myself and raped my sister.
