My fiancée, Izumi, is getting married soon. She said she was going to have a barbecue with her college club friends for the first time in a while. Her college club was known for being a bit wild, so I was a little worried… "Everyone's grown up now, so it'll be fine," she said before heading out. She came home late that day. Yuki didn't say anything in particular—but my bad feeling was right…! Later, I found a ****** video on an adult site with a woman who looked just like Izumi! And as I continued watching the video, I even found an unbelievable orgy video…! [※The video of my fiancée that led to this discovery will be released at a later date!]
