My wife has always been a bit of a prude sexually. That's not to say she only enjoys the missionary position, but very rarely is our sex life spiced up by toys or role play for example, and she also gets embarrassed at any mention of sexual fantasies (although she does like dirty talk every now and then!).
At a little over 5 foot tall, my wife verges on petite, with long brown hair usually carefully straightened each morning, and the most wonderful, full D-cup tits which have stood the test of time now she is 40. With a classic hour glass shaped body she turns heads (male and female I might add), something though which is usually missed by her as she can't see how sexy she is.
Only once have I managed (after a few drinks) to get my wife to role play one of my fantasies -- to watch her fuck another cock. On this particular occasion it was a dildo I had purchased in the hope it would ignite some form of sexual release and break from her normal prudishness. She really hadn't liked the dildo when I had first introduced it, more I think as she saw it as 'dirty' rather than fun or kinky. On the rare occasions she wanted me to lick her clitoris I had once or twice slid the dildo into her wonderfully tight wet cunt. The dildo was not a life like one, just a fairly standard 6 inch purple rubber one (about the same size as my own cock) with a suction cup on the bottom, but she always protested when I introduced it because it made her feel dirty (though the occasional gasp when I was sliding it in and out of her did make me wonder if she did in fact enjoy it!).
It was on one of these occasions when I managed to partly fulfil one of my fantasies. Having had a few drinks and feeling slightly more carefree than usual I had gotten her sufficiently worked up and wet that I suggested introducing the dildo, and specifically told her I wanted to watch as she fucked it herself without me sliding it in and out of her cunt. After a little bit of resistance to my surprise she agreed. I wasn't going to waste this opportunity and had the dildo out and lubricated quicker than you could imagine!
I handed the dildo to my wife who reluctantly placed it at the top of her inside thigh. She looked at me with some trepidation and apparent mild regret at having agreed, but I knew by how wet she was and the squeezing of her tits she was doing meant that she was desperate for a cock inside her. I knelt on the bed by her feet as I watched in anticipation, by mouth dry with excitement and my cock straining in my hand, as she gave in and slid the dildo into her now very wet cunt. I watched as she slowly slide the first inch back and forth past her cunt lips as she closed her eyes enjoying the sensation of the dildo. It was the most glorious thing I had ever seen my prudish wife do and decided to see if I could push the situation further seeing as she seemed to be getting into it.
I moved round beside my wife, hearing her breath get shallower as she continued to massage her tits and allow the dildo to work its way in and out of her. I leant down to take one of her full and erect nipples in my mouth and licked it gently to which she let out a long moan. Sensing the moment I leant to her ear and whispered that I wanted to watch her properly fuck this cock. She looked at me with a sense of puzzlement but I wasn't going to stop long enough for her to say no and come back to her normal prudish self.
So I removed her hand from the dildo and slowly slid it from her dripping cunt. I knew she was close to cuming so had to work quickly before she knew what I was planning to do. I took her by the hand and gently moved her off and round to the foot of the bed. I told her to get on all fours and then suck the dildo to the wooden bed frame so that it was jutting proud in direct line of my wife's hungry pussy.
To my surprise my wife sank herself onto the dildo without any hesitation or reassurance needed. Within a couple of thrusts to my delight she was taking the whole 6 inches and loving it! With eyes closed and tits wobbling beneath her she groaned with every stroke of the dildo inside her. I couldn't stop myself from stroking my cock knowing this was the closest I was going to get to my sexually reserved wife fulfilling my fantasy of watching her fuck another cock. I struggled to focus on not cuming myself wanting to make this moment last but the more I watched my glorious wife fucking this cock the closer I was to climaxing.
As I wondered how much further I could push the situation and considered moving my cock round to my wife's mouth I realised her breathing had changed and that she now had one hand buried between her legs furiously rubbing her clit as she slid faster and faster along the full length of the dildo, getting closer and closer to climaxing. The sight of her playing with her clit and clearly enjoying the cock inside her was too much for me and I exploded all over her back with the most intense orgasm I'd ever had. Seconds later my wife's body started to shake and convulse as her own orgasm took over with the longest and loudest groan I had ever heard her make.
She collapsed on the floor with her ass in the air and the dildo still inside her trying to catch her breath. My wife had finally released herself from her inhibitions I thought. This was the start of a whole new chapter in our sex life. To my disappointment once my wife had removed herself from the dildo and gathered herself on the bed she almost instantly said she felt dirty and made it clear she wouldn't be doing anything like this again.
As the next few weeks passed I kept coming back to this occasion, wondering how I could manipulate a situation in order to try and get a repeat session. In the hope of further living out my fantasy I ordered a realistic 8 inch black dildo complete with balls and suction cup, my ultimate fantasy being to watch my wife's tight cunt getting fucked hard by a big black cock and her groaning in ecstasy as a result.
To my disappointment there never was a repeat performance. I did introduce the larger black dildo on one occasion, taking my wife by total surprise as I slid this weapon into her tight cunt, stretching it beyond the limitations of my own cock. The speed at which she orgasmed told me she enjoyed the feeling of this very large cock, but I was dismayed that yet again her prudishness took over once the orgasm subsided, and she told me in no uncertain terms never to produce this particular dildo again.
