She offers herself

"We'll have to use me. The imp children require a lot of mana from the mother based on my experiments. It's why all the goblins and brood mothers I collected all died without even giving birth. You know what they say about having to do it yourself. Besides.... controlling MY army will be even easier if I am it's brood mother."

"Seriously?!" He said in surprise. "You would become a breeding **** for me?"

She then slaps his face. "Do not call me that! I am just gonna be your mate for a while till we make enough Implins (imp goblins) for an army. I mean... I saw in my experiments that baby goblins grow fast in mothers and birthing them is relatively painless and the imp genes didn't change that." She then blushes a bit. "Beside, I admit I get turned on by the idea."

Kazex's eyes widened "This girl might be a natural born slut, she just has too much pride to give herself to her own desires" he thought to himself and then smirked. "Well then, I guess we have a deal. lead the way... mistress?" He couldn't lead her back home as he didn't know if she'd mess with his brood or existing women so he asked her to lead the way before mentions of his home could even be made.
