My coworker's girlfriend, with whom I share an apartment, is a perfect, stunning beauty—absolutely top-tier. On the day of a hot pot party, while my coworker was out shopping, I seized the chance to taste her body, even just a little. One night, seeing that she didn't mind being watched during sex with my coworker, I boldly thrust into her right beside him as he slept. Drawn in by her charm, the story unfolds as our relationship naturally deepens.
