My sister's friend came to my house to play. Whether on purpose or carelessly, her panties were fully open and visible. I thought I was looking at her secretly, but it seems my sister's friend knew right away... "Getting turned on by looking at your sister's friend's panties is really crazy, haha," she said, and I bent over to run away, but she suddenly got on top of me in the bathroom and came inside me. That's when my life as her slave began. This is the video of me being played with after she found out about my weakness. (Yuu, Nerima, Tokyo)
