Anna walked slowly around in her robe, cleaning as she went. Her long brown hair went almost to her waist and her warm brown eyes danced with thoughts of her beautiful Mistress. Mistress Lex was at work and trusted her slave with all the duties. From cleaning and cooking to being naked and ready for her Mistress' soft hands. Walking slowly she dusted and whipped the coffee table. Her thoughts went to the deep blue eyes of her Mistress and the blonde locks that surrounded her face. A sudden warm body snuck up on her and pressed against her tight center.
Anna relaxed as she felt the familiar bulge of her mistress' favorite strap on. Soft yet rough hands caressed around the robe, pulling it open slowly. Lex pawed at the beautiful B cups in her hands before rolling the nipples hard causing painful pleasure.
"Mmm... hello my slut." Her hand traveled lower meeting a flurry edge of underwear, "Oh! Tsk tsk. Looks like my little PET is in trouble!"
The slave cringed at the title pet. Whenever Mistress used it, it meant that she had been bad. She had broken a cardinal rule; one that had been her idea in the first place.
"I'm sorry Mistress..." Anna whimpered.
"No pet. You should be very ashamed. I was going to sneak in and fuck you hard against the wall." Lex pushed Anna hard to the wall causing the slave to tremble in pleasure as she slid to the floor.
Lex walked over to loom over her pet in disappointment. Upon instinct the trembling woman reached for her Mistress' pants and unzipped the zipper to pull out the large lady cock inside. Before she could place her mouth on the prize Lex pulled her up by her hair and slammed her face into the wall pinning her.
"No PET you don't deserve that cock." Lex grabbed the robe and ripped it up to clear the view of her slave. She pulled up the panties to give a wedge. Anna whimpered softly as Lex finished unzipping her pants and pulled out the cock.
Pinning her pry to the wall Lex began to thrust into the panties, barely able to penetrate her pussy. "See what underwear does?" Lex gave her own groan of frustration as she could not get the release that she herself wanted. The screams of her pets pleasure were taken away from her by the garment.
When realization came to Anna tears began to roll down her face. Because of the rule she broke she not only upset her, but her Mistress couldn't get pleasure. It was her life to serve her Mistress, as it had been for over two years now. As the tears came down hard sobs began to rack her body.
"I'm so sorry Mistress!" she half sobbed half whimpered.
Lex pulled away from the sobbing woman and as she hit the ground in her tears Lex pulled her up. With a tender touch she whipped the tears away then commanded, "Go get six pairs of underwear and the collar my pet."
