The professor, a bear of a man, teaches yoga with a hidden intensity, his gaze often straying to one student. After class, he invites the student to stay, the dynamic changing as the student strips off his tight yoga pants at the professor's command. The student's ass is firm and round, and the professor can't resist. He spits on the student's hole, his massive, veiny cock throbbing. He fucks the student hard, using him like a toy, his big dick stretching the student's tight ass. The student takes it like a champ, his own cock leaking pre-cum as he's pounded, his moans echoing in the empty studio. The professor cumshots all over the student's red, used hole, leaving him breathless and spent, a testament to their rigorous, forbidden lesson.
