First bit - just a minute or so.

I'm wearing normal clothes and talking to my boss.

I say something like "I agree that if I give myself up for a weekend, my debt is cancelled."
He says that's right but he's free to use me however he wants, and can me you tied up for the whole time.
I hesitantly sign a contract on the desk.

Second bit -
I'm wearing a pink and white mini dress.

I'm lying on the bed bound with tape. My wrists are taped behind your back and there's tape above and below my breasts around my arms. I'm gagged with a ballgag.

He pulls my so my head is tilted off the end of the bed and starts fucking my face. I'm OK at first but after a little bit start trying to ask him to slow down and complain that I can't breathe. He just ignores me so my complaints are cut off by his dick going into my mouth.

He cums in my mouth and immediately sticks tape on top, wrapping it all the way around my head. He says this is to make sure that I swallow. He also says that there was too much complaining and that'll need to be fixed next time then walks out and leaves me to struggle for a bit.
