He ignores her

Michael just keeps walking back to his seat, prompting a shrug from the teacher. "Suit yourself," she says, looking down at her phone and making a few adjustments on the app, dialing up Michael's sensitivity massively, and dialing up the size of his cumshots to match. Then, she presses the ejaculate button.

Michael tenses suddenly on his way back to his seat as his cock tenses and spasms. Pleasure explodes behind his eyes, and his body is wracked with a shockingly powerful orgasm. His eyes cross obviously, moaning lewdly as it brings him to his knees. His shaft pumps again and again, pouring squirt after squirt of cum into his jeans. Before long, there's a damp patch of jizz spreading across the front of his pants, his boxers unable to contain the flood of cum. It even starts pouring down his thighs as he kneels there between the desks, dimly aware of the other students laughing at him in the background.
