She was squeezing his cock now and rubbing her hands all over the bulge of flesh at his crotch. The poor old man was frightened to death. Susie released her hold on his prick and quickly pulled her T-shirt up over her head. She wore no bra. Then she pushed her short skirt down and wriggled out of it, making her round, young titties bounce. Only her tiny pink bikini panties remained. In a few seconds they were on the floor on top of the skirt.

The janitor was incredulous. Never would he have believed it. He didn't even believe it now; it couldn't be happening. This must all be some strange joke or dream. Such a beautiful and sweet little girl, naked in front of him. And she had touched his cazzo, like a putana, a whore, but she wasn't one. She was the nicest person in the school. His confused mind couldn't reconcile these two opposites.

"Here, Mr. Mascalla, don't these feel nice. They're only small now, but soon they'll be bigger and you can feel them then too. Your hands feel so good on me."

She had taken his trembling hands and pressed them against her titties. They were not at all small, and for a thirteen-year old girl they were remarkably full and fleshy.

His hands just lay there, unmoving, pressing against her erecting nipples. Susie took advantage of the old man's shock to reach down and undo his belt with her skilled and practiced fingers. Doing so pushed her titties harder against his palms. She was pleased to feel some resistance.

He was pushing back, at least a little.

In a few seconds the old man's trousers fell to the floor. A moment later Susie was pushing his underwear down his thighs. His cock hung limply, still in shock, but the young girl was delighted to see it. It was huge. Almost as fat as his arm, maybe even thicker, even though it was still soft. It looked so strange hanging from such a small man.
