Brother and sister play rock-paper-scissors for a big prize! Sister: Shio, 23 (office lady) Brother: Takumi, 21 (virgin) "I don't think I'd get an erection even if I saw him naked lol" "I wouldn't get excited, we're family lol" Now that they're both grown up and mature, they take on the project without realizing that this logic doesn't apply. However, they immediately take back what they said lol. Their brother's penis gets so hard they have to take a double take lol. He's a virgin, so it can't be helped, but he's totally turned on. What's even more surprising is that the sister, despite being embarrassed by his hard cock, is getting turned on no less lol. After that, it escalates into what is known as intense incestuous sex lol. It's great that they've graduated from being virgins and that the brother and sister have become closer! That's what I'd like to say, but I'm curious to see how their family relationship will develop in the future. At first, I intended it to be a variety show, but from now on I'm going to follow this brother and sister as a documentary lol.
