The professor's thick, veiny cock slides in and out of the teens' tight holes, their bodies squirming with pleasure and a hint of discomfort. As he fucks them, he smacks their asses, leaving red handprints. Suddenly, one student lets out a loud fart, the scent filling the room. The professor chuckles, spanking her again, and the students giggle, their eyes watering. The professor, turned on even more, fucks them harder, his balls slapping against their clits. He pulls out, stroking his cock, and the students open their mouths, eager to catch his hot load. He obliges, cum shooting onto their tongues and faces, some dripping down to their tits. The students lick it off each other, their bodies glistening with sweat and cum.
