I secretly filmed Hikki's sister for surveillance purposes. It turns out, she has a strong sex drive just like her brother and is always masturbating! She can even make herself squirt! I presented such a sister with food and adult toys together. Although she hesitated at first (Is this that kind of thing?), she soon understood and started using them obediently from that day on. While monitoring her, I couldn't control my excitement and ended up in her room... I lustfully desired her matured body and used the toy I gave her for vaginal torture! Though it wasn't visible on camera, Hikki's sister was still smooth down there! I made her lick my penis in a frenzy and forcefully inserted myself into her hairless slit. As I thrust like an animal, she responded with lewd moans! In the middle of thrusting, she screamed 'I'm going to cum, I'm going to cum~', so I stopped thrusting and pulled out my penis. She then squirted a fountain-like amount of female ejaculation!!! Although she is my sister, she is the most erotic woman, and since then, I have been training her to be an M girl every day...
