My wife was pretty vanilla when it came to sex, no sex toys of any kind, she's had a few partners before me but limited experience. I knew her last boyfriend and he was always bragging on how large he was. I was concerned on how well I was pleasing her. I asked her if she was satisfied with our sex together as I knew I was smaller than her last lover. She smiled at and said that size doesn't matter, I asked her if I could challenge that statement, she asked how I was going to be able to do that, I could see she was curious and intrigued. I told her I would get a couple of dildos of different sizes to simulate different sized cocks and introduce them into our sex play. She said let me think about it. close to a week went by when her curiosity got the best of her and she agreed to my experiment. So I bought a 9 1/2" by 1/7/8" dildo and I also purchased John Holmes UR3 dildo. I didn't show her the dildos as I didn't want to scare her but did inform her I had bought toys for my experiment
She asked when I wanted to try them on her, I told her it would be a surprise so she wouldn't be so apprehensive and nervous which could hinder her receptiveness to the toys. A few weeks went by when one night I had gotten her really worked up during foreplay, I had the toys close by so I could grab one when the time was right. I got the smaller one to start with, as I was giving her oral I squirted some pub on both her and the dildo and started to rub the head on her pussy, it must have felt good as she spread her legs wide and started moving her hips and putting pressure against the dildo helping it to slide into her. As it entered her she gasped and pushed harder taking the dildo in deeper, she started to moan and rock her hips faster. After several minutes she had it all the way in , at this point she had a massive organism, she had never came that fast or hard with me inside her. I fucked her for a good fifteen minutes with the dildo while she continued to have multiple climaxes, both big and small. She said that was getting tired so I replaced the dildo with myself. I couldn't believe how good she felt, A bit loose but hot, wet, very creamy, I discovered I love sex with a freshly used, loose, hot, creamy cunt. Afterwards we talked about the experiment, she admitted that she really enjoyed the sex and it seemed that size does make a difference. She didn't realize how much she would enjoy fucking a big cock again and asked me if I was upset with her, I told her I was thrilled watching her enjoying a huge cock, it was a real turn on for me.I definitely was not upset but would like to include the dildo into our regular sex to which she agreed. But the story does not end there, after 5 or 6 months I noticed that the dildo wasn't giving her quite the same level of pleasure as when we first used it, so another opportunity presented itself and so during our regular sex play and after using the small dildo I switched it for the big dildo. I told her the dildo needed more lub, so I removed the small dildo, lubed. Both her and the big dildo. as I pressed it against her pussy she said what was I doing, I told her that I was trying the other dildo and relax and enjoy the sensations. She cooperated with me slowly pressing against the dildo as she moved her hips to allow her pussy to open up and accept the bigger cock. After a minute or two the head popped in and she said " oh *******". I stopped for several seconds to allow her to adjust to the bigger size. Then I started to inch the dildo slowly into her, giving her time to take it. After around 5 minutes or so it was a good six inches in and she was responding by rocking her hip, moaning very load, saying yes oh yes repeatedly. As she loosened up, she was starting to enjoy the new toy, talking about how big it was, how it was stretching her pussy, how full her pussy was, then she had the biggest, most explosive climate I had ever seen. She went absolutely crazy and kept telling me to don't stop, keep fucking her. She got so loud I thought the neighbors would call the cop on us. This continued for a good while then she said she was spent, so as before I replaced the dildo with myself, she was very loose a I asked if she could even feel me, she said she could as she was super sensitive after so many climaxes, it only took me minutes to reach my own climax. As we talked afterwards she said she's never been so turned on, she was in sensory overload, it was the most stimulating, satisfying sex she has experienced to date.she absolutely loved having her pussy stretched and stuffed full, she'd never experienced anything like it before.and said I was going to do this with her again. She then asked me t show her the dildo and when I did her jaw hit the floor. She said no way that fit inside her, I said it did and it was the hottest thing I had ever seen, I thanked her for allowing the experiment and she thanked me for the fantastic sex. I have since bought her a "Bam" dildo, we only use this when she's super hot and horney, it gives her massive climates but leaves her sore for a couple of days, but each time is better with less soreness,faster recouping, she has become a size queen and we both enjoy it.it's definitely built up her confidence for when it comes time for het to try a real BBC, which was my plan all along.
