"Well," he said aloud. "This should be simple enough."
He wrote, "My penis and testicles are those of a fully grown adult..." He thought a moment, then he added, "which are larger than average, and they do not affect the development of the rest of my body through hormones except for allowing me to feel sexual stimulation and have sex."
He set down the pen and looked at his crotch, a bulge was growing between his legs. He shifted his position to angle his penis out of the hole in his boxers. It reappeared before him, like a worm emerging from the dirt, growing darker as it grew longer and thicker and harder. In seconds it had become an 8 inch long cock, fully erect and thick. It must have looked absurd, jutting out from the crotch of a 9-year-old boy. He grasped it in his little hand and realized that he could just barely encircle it with his fingers and thumb. It felt warm and heavy. He could feel his balls sitting heavily bellow, resting warmly against his thighs. He moved his hand gently along his giant cock up and down and felt a jolt of sexual stimulation at last. He moaned happily in his little boy voice. "That's the stuff," he said. He spun his chair to face Janet again, still sliding his soft hand up and down his hard shaft.
"Blow me," he ordered.
"Yes, sir," she replied and knelt down again. She guided his bulbous cock's head to her lips and swallowed up the front of his member. He let go of himself and took hold of the sides of her head and started to rhythmically pull her head down onto himself. "Oh, God, yes!" he cried, the passion of his inflection in deep contrast to the innocent sound of his voice. Soon, she was deep throating him like a pro, and he felt ready to pop. "I'm coming!" he cried. "I'm coming!" He erupted down her throat and felt the orgasm rush through his little body like a tidal wave, growing stronger with each spurt. It was almost too much to take. The pure pleasure was so overwhelming. It filled him up completely. No, it overfilled him. He felt as if it would burst out of his skin. His mind went blank. He gasped. It WAS too much, too much pleasure for a boy's body to take. His body seemed to melt away into the orgasm, "Dave" disappeared, and there was only the orgasm. He passed out.
For a while, he drifted in darkness in a endless sea of pleasure, dead to the world and out of control of himself.
He came to some time later. It might have been a hundred years for all he knew, though. He lay there slumped down in his chair, breathing heavily, unable to move. "J-Janet?" he muttered.
She was still kneeling in front of him. "Yes, sir?" she asked pleasantly.
"H-how long..." he swallowed. "How long was I out?" he wheezed.
"Only a few minutes," she replied.
"Help me... help me sit up." She grasped him gently but firmly by the shoulders and pulled him upright in his seat as if he weighed nothing at all. "Thank you," he said as his fumbling fingers absentmindedly tried to adjust his tie and then slide his deflating cock back into his underwear and zip it away, noting only vaguely that his pants must have been specially tailored to fit such a large member.
"Can I help you with anything else?" Janet asked.
Feeling more in control of his movements as the seconds ticked by, he grabbed a tissue from his desk and wiped off his hands and handed one to Janet. "You have a little something on your cheek by the edge of her mouth."
"Oh," she said and wiped up the drip of cum on her face. "Did I get it?"
"That's it," he said. "Well, you can open the blinds and the door, and then you can go back to work."
"Yes, sir," she said. "I won't forget to give you that report later."
He smiled. It was all business as usual.
"Sure," he said, although Cheryl's report was the last thing on his mind at that moment. Janet opened up the blinds and door. Then, she left, still naked and huge.
He just sat there staring off into space. The afterglow of that overwhelming orgasm still lingering on.
"Well..." he said. "Fuck... I mean... fuck. That was something."
He rested there exhausted for a while until...
