Monster Girl Breeding

You are brought out of a large metal wagon with a random assortment of human men of various ages and sizes. You don't remember how you got here, but you do recall being grabbed by some monster girls late at night one day. You and the other men are led into a strange building, where you hear the sounds of screams and moans of humans being forced to breed the monster girls that paid top coin for this lewd experience. When it's your turn, you're dragged into a chamber and hooked up to an odd machine that connects your crotch and begins scanning your whole body. As the process starts, a slime girl scientist approaches from behind.\n"Let's see... checks notes "you, right?" Welcome to our little program here. The slime girl says to you as the compatibility machine whirrs and clicks, building a strange pleasure inside you as the process goes on. "Now relax and let science take its course, I'm sure you'll love how this feels. At least most slaves do."
