Glazing his teacher's buns

"Well," Paul said, flushing a beet red under his teacher's anxious gaze, "I sometimes think about rubbing my..cock on their asses from behind and shooting.. my stuff.. all over their.. buttcheeks."

The teacher was kind of surprised at the extent of Paul's revelation, but realized he must finally feel comfortable to let his guard down with her. She was secretly pleased.

"Well, Paul, that's quite the fantasy!" she admitted. "Not something these young schoolgirls would probably appreciate, though. If you promise not to try this on any of your pretty classmates, I may find it in my heart to allow you to do what you want," the gorgeous Phys. Ed. teacher told him, her heart-shaped ass still on display before the perpetually horny lad, the lycra leggings still rolled below her fair-skinned buttocks.

She tried to suppress a smile when she saw Paul's face just light up at the idea of creamimng all over his favorite teacher's asscheeks.

"Hurry, Paul!" his teacher directed. "We don't have much time!"

Paul needed no further prompting. He sluiced his incredibly long, hard cock through the crevice of his teacher's tight buns, wheezing in his excitement as his balls churned. He jackhammered back and forth for nearly a minute, his precum lubing the slice of her cheeks.

The teacher tied to remain passive, but couldn't. As Paul slid his cock along her sensitive skin, she lunged her ass back against him, ready to cum herself.

"Aaargh!" Paul wailed, taking his big cock in his hand and jabbing it mid-air.

The sexually stimulated teacher furtively came on the fingers she had jammed in her pussy as she felt her student's come spatter all over her smooth assglobes.

"Oh, Paul, you're just amazing!" she cooed, admiring his resolve and resiliency.
