The Long Term MFM Relationship With Our Housemate This is the true story about how my wife and I got into a threesome relationship with our housemate. It lasted more than four years Bill had already been living with us for some time before our special MFM sexual relationship started. He was on old buddy of mine. He is around 6' 5", blond haired, blue eyed, and well built. He even played defensive end in college. When all this started, he was helping my wife and me open a new business, a retail lingerie shop. The three of us worked on getting the interior of our new store ready to open. One particular day my wife was away on a buying day trip up to LA, while Bill and I were painting the store interior. While we worked, he and I talked about his ex, and he confessed that they had always wanted to swap with my wife and me. He said they never figured out how to go about it. I told him that was a bummer because my wife and I had also discused the exact same thing! We both laughed about how stupid we were to have missed that golden opportunity. I told him that we should not make that same mistake twice. I told him that if he was interested, we should seduce my wife to do a threesome. We discussed how to get her interested, and came up with a plan that had us both horny and hoping we both got to fuck my wife that night. That evening before dinner I mentioned to my spouse that I would enjoy seeing her model some of the new lingerie she bought for our store. I assured her that our housemate would have no objections. She thought about it, and then nodded her approval. After dinner, while she was upstairs, I told Bill that phase one of our plan had been successful. We hoped my wife would enjoy showing off for both of us. He and I both wondered how far she would go. About that time my wife walked down the stairs wearing an awesome red lace bra and matching panties. She looked so hot! My 40-something spouse is tall (5' 8"), very statuesque, has beautiful long legs, and 34C/D tits. Her tummy and buns were so tight that night that you could bounce a quarter off 'em. We took a few photos of her as she posed in various places around the room. Bill and I talked about how she hot she looked, and she seemed quite pleased listening to our comments When she got within reach, I tried to reach out to fondle her. She playfully slapped my hand, saying it wasn't fair for me to get to touch her but not Bill. I told her she was missing out on a chance to double her pleasure. My wife got my drift and smiled. Then she asked if we'd like to see another outfit. Of course both of us guys wanted to, so she went back upstairs to change. You could tell my exhibitionist spouse was getting real turned-on showing off for us guys. We had entered the second phase of our plan to get my wife to fuck me and Bill together. She came back downstairs wearing a floral print silk chemise and matching tap pants. She looked sweet and innocent, but that wasn't how she acted. After a long time of teasing and making all of us very horny, Bill went into the kitchen to refill our drinks. That was when my wife finally whispered in my ear, "Should we invite Bill to join us up to the bedroom?" I immediately said, "YES!!" I told her it was certainly all right with me. She then announced that she had one last outfit she wanted us to see, and ran upstairs to change. I love it when a plan comes together. I let Bill know that our plan was succeeding. I told him to be prepared to discover what a horny sex fiend my wife is in the bedroom. He was gonna be shocked when he realized how completely different my wife's sexual personality is from her public persona. Who would ever guess she's a submissive gal who gets off on BDSM sex, bondage, nipple clamps, genital whipping, verbal abuse, public humiliation, exhibitionism, sexual torture, fetishes, leather, and latex clothes, and dildos. I was convinced that Bill and I were gonna have a great time using and pleasing her together. Instead of looking sweet and innocent as before, my wife came downstairs wearing a sheer black blouse with a tight black leather mini. She also wore seamed stockings and a pair of black stiletto heels. Bill and I commented how sexy she looked, so wicked and naughty, as she strutted around the living room. She stopped and stood between us. She said, "This time I'll let you both cop a feel," and stuck her buns in our faces. We both rubbed her hot little ass and tried to get our hands up her skirt. She moved out of reach then, and put her leg up on the coffee table to let us see better. I was pretty sure she wasn't wearing panties. At that point I asked her if she'd like to show us what she had on beneath her blouse and skirt. She answered my question by doing a slow strip tease. First, with her back toward us, she removed her blouse. We could see she was wearing a black bra. When she turned around and faced us, we saw that she had on a shelf bra that supported her tits but didn't cover her nipples! She continued dancing around the room, squeezing her breasts and pinching her nipples. She moved back between Bill and me, and let us both fondle her tits. I could tell she loved it when Bill and I tweaked her nipples. They were sticking out almost an inch before she slipped out of our reach. My beautiful spouse continued her dance in the middle of the room, standing there again with her back to us as she unzipped and wiggled out of her tight little mini. She had on a pair of suspended hose that left her buns uncovered. When she turned around to face us, she exposed her shaven pussy! Bill and I both groaned and mumbled things about her looking like such a wanton sexpot. She laughed. My exhibitionist wife strutted over to the sofa where the two of us guys were sitting, and sat down between us. Her hands reached over to rub the outside our pants, and she squeezed our hard dicks. She said, "It ooks like you boys enjoyed my slutty outfit, and my nasty little dance." She told us it was her turn to see our stuff, and wanted us to pull our pants down. We both quickly had our cocks out, and she squealed with delight as she wrapped her hands around both out dicks. She was obviously pleased that Bill's dick was a couple of fingers longer than mine Then she said if we wanted to continue further, the three of us should go upstairs to our bedroom. As we climbed the stairs up to the bedroom, my wife asked, "Would the two of you like to do something `kinky' for me tonight." She told us she wanted to be tied up while we fucked her. My wife explained to Bill that being restrained gave her something to push against, and made her cum harder. He said, "Hey, not a problem for me." My sexy spouse opened the double doors to our bedroom, climbed onto the bed, and lay down on her back. I dug around under the bed and found some long nylon straps that she and I often used to tie her up. Bill and I used them to hold her legs wide open. We tied her hands and wrists to the headboard with several scarves. We started by teasing and licking her clit, sliding our fingers around and into her twat. She was so amped up that she started cumming right away, and kept cumming as we played her quim. I don't think my horny wife had ever cum so many times so quickly. Her coochie was dripping her love juices. After those first orgasms, we let her calm down. As we finished with her, she told us that she loved our talking about her being "our submissive cum-slut." She had overheard us discussing her wanton behavior and our kinky plans for her. My wife had always gotten really turned-on being treated that way. I told Bill that light sexual humiliation has always been one of her favorite bedroom games. He said he loved that in public my wife was an assertive, outspoken business woman, but looked forward to her behind-closed-doors persona where she would be our submissive fuck doll, getting off being tied up, spanked, and loving to satisfy our perverse desires. My wife smiled at what Bill and I said about her. She whispered to us quietly, in a breathless voice, "Yes, that's exactly right... I love the idea of being a nasty little fuck toy for the both of you, to do whatever you want with my body. And ... I love being the wanton woman in this household, willing to do anything you two want me to do. I even look forward to being a submissive sex slave who must do what my two masters wish me to do." My wife's declaration of submission really got the three of us all worked up. Then we tied my spouse on the bed in the doggy position. Her entire body and hips were supported by blankets and pillows, so that both Bill and I could fuck her for as long and hard as we wanted. The two of us guys took our positions at each end of her, with me by her face, and Bill kneeling down by her ass! I lay there playfully slapping her face with my dick. We began slowly. I put my dick between her lips and into her mouth. He put the head of his huge dick to spread her labia, and entered her pussy. Each time we moved, her body moved back and forth. My cock slid further into her mouth (actually down her throat), and his cock plunged deeper into her hot pussy. I was so happy my submissive wife was letting us fuck her any way we wanted. Every few minutes when one of us was about to cum, Bill and I swapped places and changed positions. We figures that by trading off like that, the two of us could fuck her all night long, and not cum until we were ready. And he and I enjoyed doing her different ways. I enjoyed face-fucking her, while Bill said that doing her doggy-style was the best. He said that my wife was the only chick he found that he could fuck as hard as he could and not hurt her. The next time we stopped to change positions, she told us she wanted us to shove our dicks into her pussy and mouth as hard as we could, both at the same time! She didn't have to ask twice. We jammed our dicks into her as hard as we could. It almost looked and felt as if our cocks would meet in the middle of her abdomen! We slowed down our pace, and even stopped briefly, in order to always keep her right on the verge of an orgasm, but not let her climax. We fucked her while discussing how we enjoyed torturing her, while turning her into our shared insatiable nympho. We allowed her to cum a few more times, and finished fucking her until we both had our own very satisfying orgasms. Then we all needed a break. We untied her and let her go to sleep for an hour or so, while Bill and I watched a porn flick. After the flick was over, we decided to wake her up. When she opened her eyes, she saw our two cocks dangling before her face. She sucked our dicks until they were hard enough for us to fuck her again. That's when we started our first three-way cluster fuck. It continued until dawn. Bill lived with us for four years. He and I often (usually 2 to 3 times a week) enjoyed my wife together. She make it clear that she really enjoyed all the doubled attention. Now that Bill has moved on, she has asked me to find a "replacement housemate." I'm working on it.
