chemistry lab
I (18F) was hiding out in the basement biology lab at 3 AM trying to cram for finals, completely exhausted and wearing nothing but an oversized hoodie and tiny shorts. That’s when Marcus (22M), a senior who works the late-night campus security detail, walked in to lock up the floor. The sexual tension between us has been building all semester, and the second the heavy wooden door clicked shut, we both completely snapped.
He didn't waste a single second on romance or gentle talk. Marcus is built like a total truck, and he effortlessly hoisted me up onto the black soapstone lab bench, sweeping my notebooks onto the floor. He ripped my panties to the side, pulled out a massive, thick cock, and rammed himself raw into my dripping pussy. The sudden, aggressive stretch made me gasp and arch my back, but he just pinned my shoulders down and started ruthlessly hammering me from behind. He was bottoming out against my cervix with so much power that the glass test tubes were rattling on the shelves. I was a crying, gaping mess, screaming into his chest while his heavy balls slapped against my booty. When he was ready to blow, he held my hips tight, buried himself to the absolute hilt, and dumped his entire hot, heavy load deep inside my guts, leaving me completely ruined and overflowing on the desk.
