A few years into our adoption of the 'life style', my wife expressed an interest in being taken by a BBC, so I hired one, experienced but a few years younger to fuck her one evening at ours. He had been recommended to her by one of the other wives in the swinging group we belonged to, so we had dispensed with all the 'meet and greet' and other preliminary stuff. On the appointed evening, he arrived and after a drink during a short bit of chatting between them as they sat together on the sofa in our lounge with me sat opposite just observing them in the dim lighting. They progressed to he touching up her breasts and she rubbing his cock through his clothing, then he running his hand up between her legs and rubbing her pussy through her panties. I then suggested we move to our bedroom where I sat watching as they undressed each other and she sucked his cock to a full stand and he caressed her breasts and sucked her nipples before finger fucking her to her first come, which she gasped out as she violently rolled her hips against his hand. Her come was intense enough he had to help her onto the bed on her back. Knowing her pussy was wet enough from her come, he mounted her and slowly pushed his cock, longer and thicker than mine, up her with several partial thrusts until he was fully seated up her. He paused to let her get used to his size and whispered that she should tell him when she was ready to be fucked. She rolled her hips a bit to get comfortable with him up her further than any one before him (as she later told me). He then began steady fucking my wife with a medium slow pace for about four minutes. She began heavy breathing about half way with it becoming deeper and more frequent as he continued to fuck her steadily until he began pounding his cock into her. She immediately cried out a series of, " until his cock thrusts become a -of movement during which she screamed, not as loud as a person can do, but loud enough for me to know she was out of her mind with lust - something she'd never done with me. At the end, I could see his bum cheeks clench and relax several times as he bellows out, "Fuck! ... Fuck! ... Fuck!" He was coming and as he did, her hips jerked uncontrollably as she came for longer than her normal ten seconds or so. When she finished, he collapsed onto her and they lay there, he still slowly fucking her and she rolling her hips against him. As they did this, she ran the fingers of both hands through his hair and pulled his head to her face and kissed him hard, shoving her tongue between his parted lips. I'm surprised as this is the woman who told me she didn't think she could kiss a black man, but here she was tongue fucking his mouth. Watching her kiss him was almost as much a turn-on as seeing her fuck him. He was still in her and they were still fucking each other very slowly. I moved to the foot of the bed and confirmed my suspicion that his cum was leaking around his cock and smearing all around her pussy entrance. He then pushed his upper body up on outstretched arms and slowly increased the pace of his cock thrusting. I guess the kissing interlude made him become harder. He slowly increased his pace and after a couple of minutes he asked her if she wanted to be fucked again since he now could come in her again. She gripped him tighter with her lower legs around the back of his thighs and her hands now gripping his big biceps. She moaned, "Oh, God. Yes. Yesss!!! Make me come screaming like the last time!" My wife's conversion to a slut hotwife was now complete as she begged her lover to fuck her. He fucked her the same way again and she came hard again, screaming out her orgasm, which seemed to last longer than the last one, when he came in her. They repeated their come down, again with her tongue fucking his mouth for a rather long time afterward. I again moved to the foot of the bed and now saw a copious amounts of cum smeared all around her cunt and her trimmed cunt hair, as well as dripping down her bum crack - and his cock was still in her! When he asked if she wanted to go for a third time, she begged off saying he had worn her out and she needed to rest. Since I had paid for only one hour of his time, it was time for him to go. He withdrew his cock and a steam of cum flowed out of her pussy and onto the sheet below. He got up and went into the ensuite to clean up. As soon as he got off my wife, I got between her legs and mounted her, shoving my smaller cock all the way in a single hard thrust. The feeling of shoving it into a swamp of another man's hot cum immediately made me more lustful than ever, and I fucked her to a quick come, adding my own hot cum to the remainder of his which hadn't already flowed out. My wife was loving enough to loosely wrap her arms and legs around me as I fucked her. She didn't come, and at the end, she begged off any more and rolled over and was soon asleep. He had left by that time, so I locked up and returned to bed, my cock already hard again. But I acceded to her wishes and soon also went to sleep. To my pleasant surprise hours later, but still in the middle of the night, I awoke to my wife sucking my cock. I was on my back and when she had it hard, she mounted me and fucked me to a desperate come on top. It was obvious her violent hip movement was her attempt to use my cock to simulate her coming on her lover's much bigger one. And her efforts were successful as her long and violent fucking of me resulted in she coming with much heavy breathing mixed with gasps amidst shuddering and hip jerking that went on for maybe a full minute. She was totally spent and collapsed onto me, kissing and thanking me for her latest come as well as letting her have him earlier. She soon rolled off me and went back to sleep. I had come with her, but I didn't think she even noticed whilst in her intense coming. We fucked again in the morning at my initiation and she was finally mine again. We talked about it over breakfast, and since then, she's fucked him a few times a year between our other 'adventures'.
