Something isn't right

You shiver and moan hotly as you slide up and down that fat dildo. Your pussy squeezes it tightly and your juices leak hotly down it. You scream out in pleasure as your entire body spasms around that fat toy. Fuck you are going to squirt all your brain out over the toy if you keep this up!

You keep moving your hips up and down, moaning hotly as you fondle your tits. The last of the demon sluts leave the room and Mistress looks to you and the other slut. "You two done yet? Get over here!"

You tremble as you slide off the toy, your legs twitch as you catch your breath. The other girl walks by without issue, then you walk up to the demoness. She grabs your hair and pulls your face close as she stares into your eyes. "Ehh close enough!" She shoves you past and slaps your ass as you go by. "Hurry up!"

You catch up to the line of sluts, taking the very last position as you walk down a tunnel, and into a large room. There are several other tunnels in and out the room. Several coming from other pits, where you can hear lewd moans.

There is another line of girls that seem to have gotten here before your group, giving you a moment to look around. There seems to be three groups the girls are being sorted into.

In one group the girl are branded with a demonic mark and as the mark forms their tits grow much larger, and their little demon horns turn sideways, looking more like cow horns and the little demonic tail becomes a cow tail

In another group, they are branded with a mark and their arms become bird like, and covered with fathers. Their hooved feet become more like clawed talons and their tails change into a bunch of long tail feathers

In the last group, the girls are unchanged, going through as they are. Though a thin silver collar is placed around their necks. The collar is magically sealed shut with no way to remove it.

Soon you near the front and you are going to be sorted.
