Some bondage for the slut...

You push her away, breaking the kiss.
"Listen, from now on, whenever we´re alone. You are my sex **** and I will call you a such. I am your Master and you will adress me as such. Are we clear on this?"

She doesn´t even hesitate.
"Sure thing Master, what do you want me to do?"

"Undress, then come to my bedroom."

She slowly strips out of her clothes, almost turning it into a sort of strip dance. When she is naked, she follow you to your bedroom.
You´ve spent a considerable amount of you income on bondage toys, but never really had anyone to use them one. Until now.
"Wow, you sure have a lot of toys Master"

You smack her ass, making her yelp, but in a delighted way.
"Quiet, sit down on the bed with your arms behind your back."

She immediately obeys, sitting down and putting her arms behind her back. You grab a few leather straps and use them to bind her arms together. She could even touch elbows without much issue. After this, you vind two more leather straps over and under her breasts, making them stand out more.
You use similar leather straps on her legs to tie them together. But now you need something for her big mouth. You look through your collection of gags...
