"Yes. I accept you and your desire!" Joe was so overcome by the presence of the female that he roared out. He could feel an enormous pressure between his hind legs as his dragon's penis began to slide out.
Slithorin coiled even more tightly around Joe, and the contact sent a shiver of pleasure through his body. "Yes, seed-bearer. You are mine now, and I claim you as my own."
Joe trembled in desire, and need, yet a curious thing was happening. His erection was starting to fade, and while the female's presence was still overpowering, he was beginning to feel a sense of dependency instead of lust. What small part of his mind could still think realized that Slithorin was a little larger than he was. His head barely came up to her chin. No, wait. It was below her chin! He protested weakly as she continued to wrap around him. "I'm shrinking! I don't want to be smaller!"
"You must learn the ways of dragons, seed-bearer-to-be." The female was coiled protectively around him now, rubbing her head against his as he continued to get smaller. "It takes time. Much time. Why, it takes 20 human years for a dragon egg to hatch! Do not worry. You are mine, and I will protect you and raise you, and when you reach true maturity, we will become mates. But now you are becoming the dragon you should be, not the dragon you will be."
Joe was confused, but as he continued to shrink, he began to realize what was happening. The dragoness was making him younger! He was half her size now, decades of growth dropping away each minute. He felt so safe, so warm and protected. Sleepy.
What did Slithorin mean about him becoming the dragon he should be? A 15 year-old dragon? She was turning him back into a baby! Then, as he began to instinctively curl up between the massive legs of the dragoness, he remembered something else she had said. A dragon egg takes 20 years to hatch. Already too far gone to resist, Joe felt a leathery bag form around him, felt warm fluid surrond him. He was becoming an unborn dragon, and would spend the next five years asleep in his egg!
