We had been in an open relationship almost since we had met as teenagers, both in a new town. By the time we were married, a few years later, I knew she'd had sex with around a half dozen men. (In reality, I later discovered, she'd fucked closer to 50 men during that courting period, including random strangers, ex-boyfriends and men who'd she'd worked with.)

For the first 15 years of our marriage we openly fucked other people though unsurprisingly my wife had many more lovers than I did. She picked up guys in bars and at parties; she fucked men who helped her out at the gym; and she worked for a long time as a hooker in a local brothel.

She had female friends who were also sluts and together they'd go out cruising for sex and creating the experiences that make life interesting. Sometimes I would ask one of her friends on a date, knowing that the slut (and they were always sluts) would be intrigued to fuck the husband of their fuck-friend. This is pretty much how I got all my extramarital sex during the first 15 years of our marriage.

That all changed when she met D. My wife was now 40 years old, still hot and hornier than ever. This elephant-cocked guy, D, was different to her other boyfriends because he wanted to share her with his mates and with random strangers - openly, of course, but with the twist that he be present during the fucking. She got a real taste for this lifestyle and so when she and D spilt up, I insisted on taking his place.

Internet dating had just started at around this time, so we created an online profile and began trawling for action. It was just so unbelievably easy and within a short space of time we'd selected a young real estate agent from another town for our threesome partner. V was athletic, presentable, well-mannered and heavily hung - it would turn out to be one of the biggest cocks she had ever seen, and she'd seen plenty!

We met for dinner at a classy restaurant, hit it off and all walked out together. My wife had been on my arm on the way in; but was clinging to V on the way out - the young waitress was openly shocked, to our amusement. We went back to his hotel room and he invited us to take his bed while he showered - my wife and I undressed and started kissing on his bed. V undressed, stood close to us - his dick was no more than 6 inches from our face - and then turned for the shower. My wife was visibly shocked and horned-up by the sight of V's enormous penis.

When he returned from the shower, V pretended to be surprised to catch us fucking. My wife kicked me off and beckoned V to approach - he hesitated, and asked if he could fuck her bareback. My wife agreed without hesitation - I was learning a lot here, including that my wife was a sperm slut and a size queen. She got down on her hands and knees and crawled towards V before raising her mouth to his cock and a cupped hand to his balls. She kissed and licked the tip of his penis before delivering a dozen or so blows where she could take no more than the head of his dick in her mouth. In short order, she rolled onto her back, spread her legs wide and used her fingers to pull back her clean-shaven cunt lips to reveal a moist little pussy.

We have a cherished photo of the the moment V first slid his weapon into her. After twenty something years of an open relationship, it was the first time I'd actually watched her fuck another man. Over the next fifteen years, we would go out most weekends to socialise with single men and sometimes couples. We would usually have sex with them afterwards. After meeting V, I have since watched several hundred more men fuck my gorgeous wife.
