It's the story of a brother having sex with his sister again, but this time he gave her a high dose of sleeping pills and then had sex with his sister. First is the story of the Kawamura brothers. When Kawamura was exercising to prepare for bed, her brother came in. He helped her relax her muscles and then secretly poured sleeping pills into Kawamura's water bottle. Because the water was the same color as the sleeping pills, she didn't recognize it. She drank the entire bottle of water in one go, the two brothers sat playing on the phone for a while, then Kawamura fell asleep and collapsed on the bed. Just waiting for that, my brother kissed my sister's lips, hair, and cheeks. When he saw that she didn't react, he took off his shirt and started having sex. Next is Hoshizora. While reading a story, her brother secretly put sleeping pills in a bottle of water and gave her to drink. After reading a few pages of the story, she fell asleep. Her brother groped to see her reaction. When he didn't see anything, he took off her shirt and skirt to have sex. He also prepared a sextoy to play with his child while he was sleeping. Another sister in the same situation is Saito. While preparing to go out to play sports, her brother secretly looked at her butt through the door. He went in and asked her for a sip of orange juice. The younger sister obediently gave it to her brother without knowing that he had then put sleeping pills in the orange juice. After mixing it, he gave it to her and told her to drink it all, then the two of them sat down to talk about her exercise. After a while, Saito felt sleepy and went into his room to lie down. Seeing that she was drugged, Saito's brother touched and had sex with her. Finally, there's the pretty short-haired girl Miyazawa, who was lying down doing yoga online when her brother opened the door and took a peek at her butt. Unable to resist his sister's round butt, his brother mixed sleeping pills in water and gave it to her to drink. Miyazawa asked her brother to teach her yoga, and after a while she fell asleep. Taking that opportunity, the older brother raped his younger brother right in the living room. Younger sisters with such lecherous brothers are truly pitiful. And in the following days, the girls will probably be given sleeping pills and raped by him again.
