My student was being naughty again — she refused to draw the assignment and started arguing back at me. Suddenly she pushed me hard onto the chair. I was completely confused and shocked when she climbed on my lap and began intensely dry humping me in her tight jeans. The firm jeans rubbing against my cock created overwhelming heat and friction that I couldn't ignore. When she took off her shirt and continued topless, the sensations became even stronger. Despite my confusion, the relentless grinding made me lose control and cum hard in my pants.
