Moto In-Cha no Kyonyuu Yariman Imouto ga Ero Sugite, Onii-chan wa Mou...!!

I have a sister who's two years younger than me. She's the plain, bookish type, so I never paid her much mind. But one day, everything changed. That was the day she got a cell phone. After that she got into makeup, started to dress flashy and dye her hair, and got pretty cute... she was like a totally different person. She also started using lots of dating apps and playing around with men. She's become a real woman, and lately I've found myself sort of fascinated... One day I walked into the living room, and there she was asleep on the couch. Her sexy body was utterly defenseless. So, I had my fun with her tits, ass, and pussy, and then I kept going... Later that night, I opened my eyes, and my sister was on top of me! She said she was getting revenge for earlier. A live-action AV adaptation (MUDR-252) was released on Mar. 15th, 2024.
