By relieving the tension

Michael squats behind the sobbing girl and runs his hands up her big, soft thighs. He squishes one ass cheek in each hand, savoring every opportunity he can get to just play with a classmate's body. Then, when seeing and feeling his fingers sink into her welcoming flesh finally started to get boring, he grabbed the fabric of her leggings on either side of the over-stressed central seam and pulled.

It didn't take very much force at all to split her pants wide open. As soon as he made the initial tear, the sheer force of her compressed buttocks took care of the rest. In the blink of an eye, the entire rear seam of her relatively conservative yoga pants had split completely.

Michael jerked the hole open wide, and actually had to manually spread the girl's huge, pillow-y ass cheeks to even find the tiny little g-string she was wearing.

"That is absolutely beautiful," he muttered, mostly too himself, before burying his face in her crack to plant a kiss on her sweaty, clinched sphincter.

"How dare you even try to hide a sight like that!" Michael continue when he finally came up for air. "I should make you go pantsless for the rest of the year!"

The girl's whole body -- ass included -- blushes at that idea.

"R-really, sir?"
