My girlfriend, I and her friend Aoi often hang out together. When she wasn't looking, Aoi would hold my hand or lean against me, so it seemed like she had a crush on me. One weekend, she was going on a family trip, so we didn't see each other for three days. On the day she left, Aoi and I ended up having an affair without either of us inviting her. After that, we had sex over and over again, as if to make up for the times we hadn't had before. We had sex almost everywhere except when we ate and slept. Our time together passed by in an instant, and the day she would return from her trip was fast approaching.
