"Oh, fuck, teach," he groaned.

"There! Now you'll just on my big titties!" Karen's oversized tits shook lasciviously as she leaned forward and again wrapped her fist tightly around the root of his cock. "Now where were we."

Again she captured his red, drooling cockhead between her lips; this time puckering her cheeks so sharply that golf balls could have fit into the indentations. Karen slurped and gurgled noisily as she sucked, his cock meat as hard as she could.

The cum load had receded back into Mitch's balls in the interval, but the boy gasped as it quickly started to come up again. Fondling his congested balls with her left hand, Karen feverishly jacked his prickshaft with her right.

Then – again, at the last possible moment – she pulled her hand and lips away, and giggled as his stone-hard prick quivered helplessly before him.

"Fucking bitch!" Mitch shouted. His expression was so knotted with frustration and anger that she wondered if he might hit her. "Goddamn you, you're fucking torturing me!"

"But Mitch, I was just thinking," Karen purred innocently, "I don't know if I want you to cum yet. It's not fair to me. I think I'd like you to suck my pussy first!"

Karen kicked off her heels and slid the pantyhose down her long legs, leaving herself naked. As Mitch looked at her furiously she wiggled her bare ass to the edge of the chair, planted her feet on the edge of the seat and spread her legs, revealing the hairy triangle of her pink, wet pussy.

"Goddamn you!" Mitch rubbed his aching prick and looked at her miserably. "I want to cum, Goddamn it! You fucking whore!"

"You will, darling! But first you have to suck my pussy!" Giggling, Karen dipped a finger into her juicing cunt and fingerfucked herself before the student's eyes. "I'm all gooey down there, Mitch. Ummm, can't you smell it? It tastes really good!"
