IPZZ-246 Kana Momonogi at a university drinking party, plied with alcohol and gang-banged while her boyfriend watches the video later

The narrator and Kana are second-year students who have been dating a year. He thought cuckold porn had nothing to do with him, but then he found a video from the club party. It shows Kana surrounded by naked men, happily giving blowjobs and taking turns being fucked, cumming repeatedly with an ahegao face. He feels frustration and regret, but the video gives him an erection.
