I (21f) Fucked my math professor after class

I stayed behind after calculus like I’d been doing for weeks. When the room emptied, I walked up to his desk. “I can’t stop thinking about you.” He looked at me for a long second, then said, “This is a bad idea.” “I’m twenty-one,” I replied, stepping closer. “I know what I want.” That was it. He pulled me in and kissed me hard. Clothes came off fast. He sat me on the desk, dropped to his knees, and ate my pussy until my legs were shaking. I came on his tongue in under a minute. Then he stood up, pulled out his cock, and pushed into me deep. He fucked me right there on the desk, rough and desperate, one hand over my mouth so I wouldn’t moan too loud. A few minutes later he pulled out and came all over my stomach. We caught our breath, he kissed my forehead, and whispered, “Next time at my place.” I just smiled, fixed my skirt, and said, “Yes, Professor.”
