Have your new continue worshiping your feet

"Well Rebecca, I think the tables have turned. For too long Monster Girls have abused and enslaved humans with their feet. Now you have been enslaved and I want you to worship my feet. Get that **** tongue to work monster!" Mary delighted in mocking and ordering her new **** around.

Rebecca bent to the task, dragging her long monster tongue over Mary's feet, licking her soles, the arch of her foot, in between the toes and everywhere. Mary gave a sigh of pleasure.

"This is going to be great. Every day after a long day of walking my sweaty feet get to be cleaned by you."

The succubus stayed silent as she continued her oral service. She hated how she had been reduced to this position but thanks to the agreement they made she was stuck. Her magic compelled obedience. A foot **** was her fate.

"And you know my quest just got a lot easier. I fully acknowledge I got lucky with my sword being in the right place. Having a powerful Monster Girl at my side will help me defeat more Monster Girls. Hmm I could maybe even create a Monster Girl **** harm with more Monster Girls just like you...."

Mary had to give that some thought. Doing so would be interesting and quite fun but it could also be risky. Creating a large group of Monster Girl slaves would draw attention and that may not be a good thing.
