tire her out

"I wish Lili has a very senstive anus, and anything that goes in it causes her intense sexual pleasure."

"As you wish."

As Lili hopped up and down with her finger up her ass and singing a nursery rhyme, she started to sweat and grow flushed.

Alysssa just laughed and watched. John sat next to her and watched Lili.

Alyssa had Lili keep this up until Lili was exhausted.

"OK, stop hopping and singing," said Alyssa. "Take your finger out of your ass suck it clean and shove it back in."

Lili did as she was told. It was obvious she felt humiliated, but also turned on.

"Lili," said Alyssa, "when I give you a command, you will respond with 'Yes, Mistress, I am your willing and worthless slave.' Now kneel."

"Yes, Mistress. I am your willing and worthless slave,' said Lili as she knelt.

Alyssa got up and left the room. She came back with a blue Sharpie. "Lili, I'm going to write something on your forehead. If you can guess what it is, you will be rewarded. If you guess wrong, you will be punished."

"Yes, Mistress. I am you willing and wortless slave."

Alyssa wrote Anal Slut! across Lili's forehead, but wrote the letters out of order to make it harder for Lili to guess.

"So, what did I write?" asked Alyssa.
