Like many men on SH, I enjoy my wife going with other men. We started quite early, just after we got married - which is now some time ago!
It all started after we read a letter in Forum magazine. The guy who wrote it described the deliciously erotic thrill of watching his wife being kissed and fondled by his friend in the back row of a cinema. They all enjoyed it so invited him to join them in bed. Watching his wife having an orgasm with another man and hearing her tell him that she wanted him to cum deep inside her really turned the husband on and made their subsequent lovemaking amazingly intense. It turned into a very satisfying long-term arrangement.
The letter turned us both on and we ended up fantasising about trying it. I asked my wife if she had anyone in mind and, in a flash, she said 'yes - Leo' - a good friend of ours who had a reputation for putting it about. I asked if there was any reason for her choice - she said that one of his girlfriends had told her that he had a nice cock and that he also enjoyed giving her oral sex. I reminded her that he had recently knocked his girlfriend up but she just smiled and said 'I'll be careful'.
I knew Leo fancied my wife - she had told me that he had kissed her and groped her breasts on a number of occasions but she wanted me to let him know that she was up for some fun and that I was encouraging her. I think he was a bit surprised but said he could understand our feelings and would be delighted to help out. I told him that she liked oral sex and would almost certainly let him have her bare as long as it was 'safe'. I also told him that it would be OK with us if he wanted to leave a couple of small lovebites to remind us of what had happened.
A week or so later they had sex at a party - his girlfriend had left early. I noticed they had both disappeared and so went searching. They were in a bedroom, she was still dressed but her mini-skirt was pushed up around her waist and he was between her legs licking her hairy pussy.. When they saw me he kissed her passionately and then pulled her to the edge of the bed and released his cock which was about the same size as mine but thicker and un-cut. I kissing her and played with her soft braless breasts as he pushed her legs apart and and entered her in one go. She gasped and wrapped her legs round him. It was so erotic seeing her respond to his thrusting.
I decided to leave them and went back to the party. I really enjoyed knowing that whilst I was making small talk my wife was upstairs being fucked by my friend. When she came to find me I loved how she looked and felt. Her swollen nipples showed through her thin t-shirt and she had a two small (but clearly visible) bites on her neck, I asked if she had enjoyed Leo's cock - had he made her cum? 'Yes' to both! Later I discovered that he had finished inside her - I think we both wanted this despite the risk. When I asked if she wanted to have Leo again she said 'God, yes', It was a huge turn on - for both of us.
Needless to say, Leo had my wife many more times - sometimes when I was at work. I loved coming home and finding them together or hearing that he had been there and that they had been playing. She never showered or cleaned up because she knew the slipperiness, scent and taste of her having been with another man would make our lovemaking so intense.
It's hard to understand why 'sharing' the woman you love deeply is such a thrill - but it works for us and I'm so glad we discovered this kink as early as we did! Sadly, we have lost touch with Leo - more's the pity!
