Completely naked, Brett stood up and Lulu put the robe on him. He walked back up to Aurora and, at a nod from him, Lulu sank back to her knees and reached inside his robe.

To Aurora's utter disgust, the schoolgirl took the massive fuck-rod and slipped her lips over it, moving her mouth over his purplish cock-head and sucking gently on it, just rubbing her fingers over his cock-head and stroking his balls.

"One of the first things the girls learn here," Brett said, "is how to suck cock properly."

His fingers played with the insides of Aurora's thighs, just above her stocking tops.

"How to suck them off, and how to tease them, keep the man on the edge of coming for as long as he wants, for hours, if he wants, Lulu's very good at it, don't you think?"

His fingers slid up Aurora's cringing body to the neck of her tight blouse.

"She knows she still has to go over the desk, so she wants me to be as hot as possible, so that I'll come quickly and save her a lot of pain."

He undid the top button of Aurora's blouse. "But," he said softly, "if your body excites me too much and I come in her mouth, it won't be her fault, will it?"

His fingers undid the next button of Aurora's blouse, revealing the clasp of her quarter-cup bra.

"If that happens, I'd have to get Karla to whip you while Lulu sucks me hard again and then goes over the desk, that's only fair, isn't it?"

Aurora threw her head back and screamed as Brett slid both his hands over her bra and took hold of the tiny clasp. He heaved and the clasp gave at once, snapping so violently her lovely tits burst out, thrusting into the air.

"Nooooo!" Aurora wailed as Brett's hands ran over her twin tit-globes, concentrating on her nipples. He slid them between the finger and thumb of each hand and pinched and rolled under. Aurora moaned with the rising pain. His fingers played with her nipples and Aurora could see that his cock was pushing faster and harder into Lulu's soft little mouth.
