Desk surprise: cock wakes my sleepy pussy wide

I was slumped over my desk after a grueling day at the office, eyelids heavy, when he snuck up behind me. Before I could stir, he flipped me onto my back, shoving my white shirt open to let one heavy breast spill out, my black skirt hiked up around my waist. My legs spread wide instinctively, needy for him, as he positioned himself between them. Now he's thrusting deep in missionary, his thick cock stretching my wet pussy while I gasp and arch, owned by the rhythm. I bite my lip, moaning softly as waves of pleasure hit, my body clenching around him on this wooden desk scattered with papers, finally surrendering to the ache I've carried all day.
