One is enough, she has a quest to do and it requires stealth!

Mary decided that Rebecca would be enough.More Monster Girl slaves would be way too risky.

"Hey" Mary looked at Rebecca. "Are you capable of turning invisible?"

Rebecca nodded.

"Good. It would be difficult to be seen in town with a Monster Girl." Mary stated.

Rebecca continued to lick Marry's feet.

"You're pretty good at licking feet."

"Grr." Replied Rebecca continuing to lick.

"Okay. That's enough." Said Marry lightly tapping Rebecca's cheek with her foot.

That caused Rebecca to stop worshiping her mistress.

Marry looked out her window and saw that the sun was coming up.

"Well it looks like you've been worshipping my feet for quite a while. The sun is already rising. I think it is time for me to continue my journey. What do you think? Who cares. You're my ****. No one cares what you think. Okay, ****. This is what I want you to do. I want you turn invisible and meet me on the outskirts of the town."

Rebecca stood up and bowed her head.

"Understood Mistress." She said as she vanished.

After Rebecca left Mary spent some time in town doing a few minor things until she left to meet up with Rebecca. Mary waited a bit until Rebecca appeared.

"Excellent. Let's go, ****." Mary said as they continued their journey with Rebecca following behind her mistress.

After they arrived at a fork in the road. The left lead down to a lake while the left lead through a cave.
