PYU-393 Kasumi is curious about her brother-in-law’s dic

While their parents are away, the older sister and younger brother are relaxing on the sofa. Then, out of nowhere, the older sister says something unbelievable: “I have a favor to ask of you… I want you to show me your dick.” “My streams are boring because they’re not erotic. So I want to see a real penis and learn from it. Please, just once.” From then on, the younger brother gets a blowjob from his older sister every day. He can no longer be satisfied with oral sex alone, and he begs her to let him put it in, but she refuses, saying, “No way. We’re brother and sister, so there’s no way we’re going to have sex.” He still begs her, thinking it won’t work, and the older sister gets on top and starts rubbing their genitals together…!!.
