After I miss the last train following her welcome party, a newly hired adult coworker asks, “Want to stay at my place?” I have a girlfriend and only plan to wait there until morning, but seeing Arina in casual loungewear destroys my restraint. I give in to her teasing, predatory seduction and fuck her repeatedly. The guilt of betraying my girlfriend only makes me harder, and every time her face crosses my mind, I pound Arina into one vaginal climax after another. A pure reverse-NTR fantasy performed by adults.
