My father remarried, so I had another stepsister, Iori. She slept soundly, almost never waking up before dawn, even if there was an earthquake. I was very jealous of her, she was loved by the whole family, I was like a surplus in this house. Knowing that she wouldn't wake up, I decided to sneak into her room while she was sleeping and do it to her. Seeing that she didn't wake up, I became even bolder, I ejaculated all the semen inside her and then wiped it off, pretending that nothing had happened. In the following days, I continued to have sex with her. Today, my parents returned to their hometown, there were only two sisters left at home, I immediately came up with an idea, let other people come to have sex with her and make more money. Thinking of doing it, I posted and soon a lot of perverts came to line up to have sex with her. And then just like that, the innocent stepsister didn't know that every time she fell asleep, a man would come to have sex and ejaculate all the semen inside her...
