I married sort of late in life at 31 years old and my wife was only 24 at the time and has not slowed down on wanting sex as of yet, even after two kids. She really blew my mind about a year ago when she wanted me to come home at lunch, she would pretend to not hear or notice me come home. I was to do whatever I wanted to her, she did not want any warning just grab her and do it. I naturally was a little surprised by this and asked her what was up with her fantasy, she gave me that look that told me to shut up and do as I am told or forget it buddy.
The first time I did it I was woefully unprepared but she still loved and wanted more well after a lot of bondage research and practice on how to tie her up quickly I have become fairly proficient at doing this to her.
The last time I did it to her I vibrated her to three orgasms fully expecting her to be begging me to stop by now but she was just moaning and crying out through everyone and never once told me to stop. She seems to love it when I bind her tightly limiting her movements and tells me each time how great I was and she loves me so much. On one occasion I had tied her to our footboard and had a ring gag in her mouth forcing her to suck my cock until I had two orgasms. The whole time she was thrusting her hips and moaning out trying to make her panties give her an orgasm, I cut them off her halfway through my second so she had nothing touching her and after I came I stuck the wand on her and she was cumming in under a minute with a huge orgasm.
I finally had to ask her again why she was getting so turned on by all of this and all she told me was just enjoy it babe. I have looked around the house for books she reads with stories of bondage or women being taken against their will but nothing. I am going to continue doing it until she tells me she has had enough I guess.
My next plan is to really surprise her in a pair of coveralls and a face mask without any warning, I am sure she will know it is me but maybe it will add more thrill for her.
