From seeing the long spear in action so much, I knew how long it was. The rod was 6 and a half feet long. The blade was 3 and a half feet long. That made for 10 feet of pure death. That seemed huge, but the dragon was over 6 feet tall himself. It took all day for Aydin to pull it out a third of the way. Every single inch of the rod was a big battle. The dragon was not letting it go. His internal muscles and core strength were still immensely powerful. The human was tiring out. Aydin simply did not have all the strength or the endurance needed to continue. "Give up already, Aydin! You aren't pulling the spear out of me. You are weak and unworthy. Go back to making your pots and bowls!" the dragon spat. Even he was panting and straining. He needed to clench down to keep the spear inside of him. As long as his hands were on it, the dragon was stuck. He could not retract it or summon it into his hands to stop him. Aydin was going to need to give up. Aydin gave it a final tug, but the spear did not move at all. I could see that something had to give. His hands slipped down to the genital slit as he heaved.
The black dragon relaxed a bit as he began to gloat. He berated all of the efforts of the puny human artisan. Aydin got annoyed and got back on his knees. He tried to tug again out of spite, but it still did not budge. "C'mon. You have to try harder than that. I didn't even tighten up for that one." the dragon mocked. Aydin licked the rod in response. A long, loud moan was ripped out of the dragon's throat. His hips jerked up in the air and a full foot of the rod was released. That surprised them both. Almost half of the spear was outside. The blue glow from the genital slit was brighter than ever. "What was that!?" the dragon demanded. Aydin said "I don't know. I-I just... did it." He then tried to lick the rod again. The dragon's voice hitched, but the rod did not move any more. He was clearly tightening up now. The spear was an analog for his dick. It was just as sensitive. With his muscles locked down, the spear was not going to budge with just a few licks. He still had to worry. If the dragon lost his control and blew his load, the whole spear would come out. It would be a game over. He did not want that.
Clearly, he was going to have to do something. Both of his hands shakily reached out towards his spear. "Alright, you little shit! This has gone on for far too long." he said as he gripped it firmly. He then began to push it back into his glowing genital slit slowly, inch by inch. Aydin could not resist the strength of the dragon. It did seem like it was a challenge for the dragon as well though. He was far too aroused to put it back in. Stuffing it in with just brute force only delayed the inevitable. He was able to push it in 2 whole feet before he stopped. He moaned and the spear emerged again. It stopped after a foot. Aydin was still kissing and licking the rod as he held on. The big and imposing dragon simply kicked the human off the bed. Aydin went flying. Without human contact, the black dragon could push it down another 2 feet inside of him. It still reemerged for a foot. The dragon rolled his eyes before deciding to just pull the spear out himself. The blade came free of the genital slit with a wet squelch noise. If I had to describe it in a single word, I would say it was lewd. After that, he simply dismissed it.
