I met my first girlfriend as a college student and was enjoying a fulfilling daily life. Then one day, she had to return to her hometown for a few days, leaving me feeling lonely and resigned to spending some time alone. On my way home, wondering how to pass the solitary night, I found one of her female friends waiting at the entrance. She was holding a convenience store bag filled with alcohol and snacks. For some reason, despite my girlfriend's absence, I ended up having a drinking session with her friend at home. Initially feeling awkward, as we started drinking heavily, the mood quickly heated up. Midway through, my girlfriend called, causing me to panic and stammer. I was determined to end the night without anything happening—but then the unexpected occurred. Late at night, the girl moved closer and made a move on me. I tried to refuse, saying I had a girlfriend, but she attacked again in the middle of the night, and eventually, I had sex with her. After that, there was no stopping it! We continued with repeated threesomes, carrying on until morning. When I thought they'd leave, the girls stayed. In the end, we had sex nonstop for three days and three nights. Guilt toward my girlfriend grew stronger, but having gone this far, there was no turning back. The thrilling sex I experienced with them was something I could never have with my girlfriend, and I became completely addicted to that pleasure.
