Break her in to her new role

When Kazex finished dragging the drider to his room, he gave her tied form another good look. He knew the race quite well, including their erogenous areas. Quite a good catch, he considered at least. Her brown eyes followed him around the room as much as they could, full with fear. He once again rubbed her back, where the halves met, bringing her pleasure as she lay on the floor, writhing in her bonds.

Kazex knew the race were formidable fighters, and decided it would be best to keep her tied up until her will was completely broken. That being said, before the first go, she had to drink a very special potion, one that would ensure any babies were born pure-goblin. Sorting through his room, he quickly found it, and added an ovulation potion he mixed in. Mixing potion was generally seen as dangerous, but this combination had been used for centuries to boost goblin pregnancy rates of other races. Of course, getting her to drink it would be easier said than done.

He untied the cloth that held the one in her mouth in, and she immediately spat it out and began to beg.

"Please, don't do this! I'll give you anything you want, but please don't do this!", she cried in a soft voice, but Kazex ignored her. She hadn't seen the potion yet, so it shouldn't be too hard to trick her using a glass of water he happened to have there. The potion was mostly colorless, so it wouldn't be easy to differentiate from normal water. Kazex guessed she was thirsty, so he offered her the water by pouring it into her open mouth.

The drider momentarily stopped her begging to greedily swallow the water, unaware she just sealed her fate thanks to the potion. Kazex smiled as he took the water away when he was sure she'd had enough potion for it to take effect. Putting the glass back, Kazex then put the cloth back in her mouth. As sweet as it would be to hear her moans, it would be a bother to put up with her screaming and begging, and he could do it without the cloth again later.

Without saying a word to the now muffled drider, he maneuvered her until he found what he was looking for. Her entrance, looking pristine and waiting for him. He had to have her on her side to gain assess, but he didn't mind that. She seemed to understand what was coming, as she shook in fear while Kazex took his dick out. He didn't know if this first go would work, but it had pretty good chances thanks to the potions.

In one swift motion, Kazex slammed into her. She was tight, but no virgin, which he quickly discovered as he pushed into her. The cloth muffled her, but it was clear she didn't enjoy his intrusion. He knew he had to work quickly to prove his worth to the witch and get his army going, so he didn't waste time and began to pound into her, enjoying the tightness she had as she desperately tried to free herself.

Soon enough, he felt the buildup, and prepared himself. With a final, deep thrust to have the best chance at impregnation, Kazex's cum flooded into her, as she cried about her fate. Once he was sure as little cum as possible was leaking from her, Kazex finally pulled back and put his pants back on. He felt spent after that, and guessed he needed some rest.

He quickly informed the witch of how the first session had gone, and that they would know if she was pregnant soon enough, but only time would tell. She congratulated him on his first success, and gave him a punch of gold as a reward. After leaving the gold in his room, Kazex went to sleep, lulled by the muffled sounds of the whimpering drider, still on her side on the floor, the witch’s magical ropes holding strong. After a few hours of rest, Kazex woke up, ready to continue his work.
