A message was sent to an application form for a sex video account active on a certain social networking site from a 20-year-old F-cup girl named Uru-chan (not her real name). She's been dating her boyfriend for six months, having met through a dating app, but it turns out he's reinstalled the app, which he thought he'd deleted when they started dating. When she looked inside, she found out he was already looking at several girls, and had already had sex with one of them, so he was doing whatever he wanted... To teach him a lesson about what it feels like to be cheated on, she decided to film a sex video and send it to him. At first it was just revenge, but she was so captivated by the sex she couldn't have with her boyfriend that she even allowed him to cum inside her - enjoy this incredibly erotic scene.
