Found out my wife's true fetish

I spent a week joking to my wife about having a stranger fuck her while she was tied up and blindfolded which she constantly yelled about when I joked about or when I sent pics and videos of the subject. After i knew she had enough of me joking about it I stopped talking about it for about a week. One night when coming back from the gym I stopped at the toy store and picked up a "thickster" which was a lifelike soft toy that you put over your cock that made it substantially thicker and added an inch of length. When I got home I did the usual seduction and slowly worked her into tie her arms down and blind folded her. After playing for a bit I got up and walked over and got the toy. I told her, "I brought a surprise home for you, you will enjoy him" as I got back to the bed She told me she "wasn't into that shit and better not" she closed her legs tight and wouldn't let me pull them apart. I didn't say anything but forced her legs apart and licked the insides of her thighs, again she told me "I'm really not into this shit" and then she just laid limp. I immediately went to eating her out, only this time WAY different than I had ever done before, while doing so I took breaks to rub her again different than ever before.. I waited for just the right time as I lined up to stick my cock with the sleeve into her pussy and said "just relax you will enjoy him"... Just as she was saying "stop screwing around you know I'm not into that shit" I pushed half of it into her... She gasped in and yelled "I'll kill you" and wiggle a bit and as I went to kiss her she yanked her face away and then just went limp again and turned her head aside and tried to reach for the blindfold. I said again just relax you will love it as I lifted my head away, she said one more time "seriously I'm not into this" just then I shoved the entire thing into her, she moaned real loud and I could tell it was uncomfortable. But said nothing, I went in and out a few times and she stopped fighting and started grinding into each thrust I pushed.. It was only a couple minutes and she began really getting into it and she damanded that I take her arms out of the straps. I thought for sure she would end the game but pulled her hands out anyways. Instead of stopping it she grabbed my ass and pushed harder to get every extra inch, I thought for sure she made me so figured I would just enjoy the ride and went in for
Another kiss... Again she turned away and said "I'm not
Kissing though" I figured she was playing along so I started increasing stroke and pace.... As she started moaning harder she barely got it out but pleaded "fuck me harder" after I increased the pace again she again moaned "'please don't cum in me" just then I realized she thought i truly was someone else! It was only seconds later and she was screaming in orgasm (which she never does) and she shot an actual load down my balls... Immediately after she was done cumin she freaked and reached up and ripped the masc off her eyes ... The look was priceless that she really thought she just fucked a stranger and couldn't believe it herself... After about 3 seconds she yells out " I knew it was you" and bucked me off... As she walked into the bathroom she turned and said, "you know I'm not into that I don't know why you did that, your never blindfolding me again!"
