A brother watches his sister Maya Kawamura finish her evening workout, then offers to help her relax. He secretly pours a high dose of sleeping pills into her water bottle, the clear liquid blending perfectly with the contents. Unsuspecting, she drinks it all and scrolls through her phone until drowsiness overtakes her. The moment she collapses onto the bed, he moves in—kissing her lips, her hair, her cheek. When there's no response, he strips off her top and begins to have sex with his unconscious sister.
Next is Moa Hoshizora, who is reading a book when her brother slips sleeping pills into her drink. She barely makes it through a few pages before passing out. He gropes her to check for any reaction, then removes her dress and panties to penetrate her limp body. He even brings out a sex toy to use on his sleeping sibling. Then there's Miyu Saito, who is packing for sports practice when her brother peeps at her ass through the door crack. He asks for a sip of orange juice, secretly doses it, and hands it back. After chatting about athletics, she feels sleepy and retreats to her room—where he follows to fondle and fuck his drugged little sister.
Finally, cute short-haired Yukari Miyazawa is doing yoga poses from an online video when her brother opens the door and stares at her round ass. Unable to resist, he mixes sleeping pills into water and asks her to drink while he coaches her stretches. Within minutes she's fast asleep on the living room floor, and he rapes his own sister right there. These poor girls have depraved older brothers who will likely continue spiking their drinks and assaulting them night after night.
