ATID-677 "The condom broke, so you have to take responsibility!" After a drunken night with a coworker, what was supposed to be a one-night stand somehow turned into her becoming my girlfriend...

Kazumi and I are colleagues, and we both have partners. ...But we were drunk and before we knew it, we were in a hotel. A vulnerable sleeping face of Kazumi that you never see at the office. Fueled by alcohol, we acted on our instincts and had sex repeatedly until morning. "Hey, the condom's broken..." "What!?" I wonder how many times it had been fired.
