I'm dating Sawa-chan, a younger girlfriend from my part-time job, in secret from the store. Maybe it's because I'm a bit sissy and not good at expressing affection, but she's always flirting with other male employees while we're at work, and teasing me. I'm so jealous and out of control because she's teasing me so much! To punish her for getting carried away and teasing me, I fuck her over and over again while we're at work, and make her understand with my dick.
