Deftly she worked his zipper down and slid her hand into his fly. Mr. Thompson now wore boxer shorts, at least on Wednesdays, though he hadn't at first. Susie remembered how much trouble she had had the first time she had tried to extricate his half-swollen cock from his pants. But this time it popped out easily, as if eager for what was to come. More eager than its owner it seemed. Mr. Thompson gulped noisily.

"Uh… Uh… the door, Miss Merton. Shouldn't we…?"

Susie usually gave him a chance to shut the door, but today she couldn't wait to taste his prick, and she liked the excitement of knowing that they might be discovered at any time.

Greedily she spread her lips over the red knob of his now completely stiff cock, kissing it with familiar affection. Then she began to lick at it avidly. The teacher instinctively pushed forward with his hips and that big round morsel slipped easily between Susie's welcoming lips. He gripped her head and began to push it in and out of her mouth, but timidly, with short hesitant strokes, while Susie sucked vigorously.

Footsteps echoed in the hall. Mr. Thompson froze, his cock planted deep in Susie's mouth.

"Please, Miss Merton… Susan! Oh God! Someone's coming. Stop it, please. We can't. Not here."

Frantically he tried to push the young schoolgirl away from his crotch, but Susie would have none of it. She bit down with her teeth – not hard enough to hurt him but firmly enough to remind him that she could if she wanted. With her teeth pressed firmly against the flesh of his trembling shaft, it was impossible for him to pull its swollen knob through them. Susie was not going to give up her lollipop no matter who was coming.

The footsteps paused at the doorway. A cheery female voice called out: "Good night, Fred. Working late?"
