That day was a home party like any other... I invited Horio, his best friend from middle school, to celebrate my engagement to my boyfriend Seiichi, and from that day on, the gears between us started to break... Taking advantage of my weakness once he had a hold on me, he pressured me into having sex with him again and again, and I was cuckolded in a cycle of depravity! "Please resist more... That's right, let's take a video of us doing it today as a memento and show it to Seiichi..." The more I refused, the more he willingly continued to violate me, and the place where we were once happy together turned into a pit of ants!
