I want to dominate her

I love my fiancé but I really want to dominate her. Just tie her up and give her sensual torture before I f$&k her real good. I can literally go for hours. 

I really just just want to tie her up and listen to her moan and watch her body as she orgasms again and again.

Ive gotten 5 orgasms out of her in 3 hours. That's my record so far. This month I want to go for 6 but we may need an IV on standby
