My partner Dahlia is a pretty asian lady from the Philippines. Just 5'3" but very beautiful. We have an online chatmate called Greg, who has always had the hots for her. Finally we decided it would be nice to meet and see how things progressed. Greg has always had a dominant streak, and liked teasing me, while I am naturally slim and smooth all over, and truth be told a bit of a sissy at heart. Though I still think of myself as straight, Dahlia has encouraged my occasional 'dressing up' to play in the bedroom. So when we finally agreed to meet Greg, Dahlia playfully tossed me her favourite white panties, with a 'butterfly' shaped hole in them and told me to put them on for our night out. Dahlia dressed in a nice blue dress, sheer nylon stockings and her strappy high heels. Full make-up and tumbling long black hair. The tight flimsy material cupping my tightly packed balls, had me squirning in erotic lust and excitement as we set off for town, but soon I forgot I was even wearing them under my smart pant-blazer combo. We shared a nice dinner with Greg in a smart restaurant in town, and afterwards a few drinks at a local disco bar. I enjoyed watching Dahlia in Gregs manly arms as they danced (I'm not much of a dancer myself). Greg had been very charming and polite and attentive to both me and Dahlia all evening. Smooth and handsome. Though I moticed he couldn't take her eyes off her all through dinner. So later Greg suggested we go back to his place for a nightcap, we were relaxed and at ease in his company, though I was not sure how things might develop. He had a super house just outside town. Very stylish and modern, and Dahlia who has an eye for design loved his taste including the many Asian objet d'art, not to mention the porsche in the driveway. We were sharing a nice bottle of wine in his kitchen, chatting about our experience of working overseas. Greg told us he had spent quite a few years with the bank in Singapore and Hong Kong and had developed a keen taste in all things Oriental...especially the women he chuckled, looking first at Dahlia, who blushed, and then directly at me... "I think its time we got started don't you?" he said, then asked to be excused and disappeared upstairs. I dont think either of us knew what he meant, but when he came back down we were both shocked when he walked back in, wearing just a tight black latex shorts, and stripped to the waist. He had a beautiful body. Tanned and buff, and obviously worked out quite a bit. It was then we noticed in his hands he carried a leather collar and leash, and several lengths of cotton rope. As he stood before us his muscular body rippled with muscles. "God how I have waited for this" he simply said... Taking my wine glass from me he pulled me to my feet and told Dahlia to help him strip me. His firm hands unbuckled my trousers, while Dahlia unbuttoned my shirt. As my trousers fell away, I remembered my girly panties, but too late! "Oh for gods sake, I might have guessed" said Greg getting over his initial surprise. I was standing before then in just my butterfly panties, and I'm ashamed to say my 5 inch cock started to immediately get hard in the cool air of the kitchen, and started jutting out of the small opening in front.. "Oh Julian you little faggot" Greg declared, how did you ever get such a beautiful woman as Dahlia?" I heard her giggle behind me... His tone had suddenly changed from the polite charmer at dinner, to authoritarian and cruel...maybe it was the alcohol I thought. Pushing me back, into my kitchen chair, Greg started to tightly bind my arms and feet to the legs and arms of the chair. This was followed by several coils of rope around my smooth hairless chest to the back of the chair leaving me utterly retrained and helpless. At this point I suddenly felt concerned..."Greg I'm not sure we are ready for this..I stammered" Ignoring me and turning to my wife, Greg declared "God you turn me on so much Dahlia...I want your lips around my cock you teasing asian bitch". Her own lips parted and eyes widened with surprise at his sudden change of tone. Now it was Dahlia's turn to be manhandled as Greg collared her in front of me, and spinning her around unzipped open her little blue dress, which quickly slipped over her slim shoulders and fell to the floor. Her small breasts were heaving in her tiny quarter cup bra, as she stood before him in her lingerie, high heels, stockings and panties. Her long black hair tumbling over her shoulders and face as she stared up at him. A vision of Filipina beauty and vulnerablity... Greg walked around her as she stood there proudly pouting at him, hands on her hips. Inspecting my beautiful asian wife. Standing behind her he reached around and cupped her breasts. Nuzzling into her neck and breathing in her perfume. She bristled at his touch, but remained where she stood. Suddenly Greg grabbed a handful of her thick black hair and yanked her head back causing her to gasp, as he kissed her roughly... "I am going to give you such a spanking you little slut" Greg stormed. Then he yanked her flimsy black panties down over her sheer stockings and suspender belt to her knees, and dragged her by the lead to his couch. My Poor wife stumbling behind him, teetering in her high heels and struggling to walk in her lowered panties. She was soon manhandled over Gregs knees, and his hand raised high into the air. It was a moment of pure erotic lust and frustration seeing him treat my gorgeous wife like this. But I was helpless to do anything but watch. "Count my strokes out loud" Greg shouted at me as his hand rained down on Dahlia smooth arse cheeks "One ..two...three.." I stammered, stuggling in my binds. In her pride and defiance, Dahlia did not let out even a cry, but I could see her bum cheeks puckering as she ground her mound against Gregs muscular legs with each slap. It was then I noticed Gregs thick angry cockhead was already protruding from the top of his tight latex shorts. It had to be over 9 inches and very thick and powerful. Glistening and ready. Pausing only for a moment Greg popped the top buton on his shorts and set his monster cock free. "No please...Greg..." I begged as he again yanked her hair and rammed his huge dick between my wifes wet red lips. Her pretty little head bobbed up and down as she moaned on his cock. Cheeks bulging and eyes wide. I felt about 3 inches high and helpless watching my wife perform for him, but my full five inches were straining through the hole in my panties, in sheer lust and frustration. After a time, Greg pushed her aside and stood up, pulling Dahlia to her feet beside him. "God your wife really knows how to suck cock" he announced. "Now its your turn Julian..." Handing my wife a riding crop, he told her to beat me, as I struggled in the chair. "DARLING! NO PLEASE..." I pleaded, but I could tell her pride had been dented, and seeing her effete husband tied and bound, unable to help her, must have spurred her on. Swish went the crop across my chest..."HARDER!" screamed Greg, as more blows followed."TEACH YOUR LITTLE HOMO OF A HUSBAND A LESSON" My head was tossing from side to side to escape the blows. Then for the final coup de grace, Dahlia brought the crop hard down on my straining little cock and balls, causing me to cry out in pain. 'FUCK yES...NICE ONE..'declared Greg from behind her. His eyes wide with lust, cupping his his heavy balls in one hand and furiously pumping his huge throbbing cock in the other. Then taking the crop from her hands, he pulled her slim arms behind her and up her back, forcing her heaving chest and her small tits to jut outwards. I watched as he bound her hands tightly with a secondary tie to her leather collar. She was now as tightly trussed as me, but at least she was still on her feet. 'YOUR WIFE IS NOW MY SLUT...' Greg announced. "YOU ARE SIMPLY NOT MAN ENOUGH FOR HER YOU WIMP.." Leading her over to me. I looked pleadingly at her. 'Please darling no...dont do this..." i whispered, as her led her behind me by her lead. "Whats going on,..whats he doing to you darling" I nervously stammered, desperately straining to look behind me. My head was tossing from side to side, but I couldn't see anything. My wife was moaning softly and I could her her kissing him as he played with her. Suddenly her head and shoulders landed on me from behind as Greg bent her at the waist thrust her forward against me. Unable to steady herself with her arms tied, She could only prop herself against my shoulders. We turned to each other and I could see she was glazed over with lust, lips parted and looking back at me. It was then I received a hard slap on my other cheek from Greg. "WHAT ARE YOU LOOKING AT YOU LITTLE FAGGOT?" " i'M GOING TO GIVE YOUR WIFE THE FUCKING SHE NEEDS, DEAL WITH IT' NO PLEASE I BEGGED...DARLING...THIS IS IT, DONT LET HIM...GREG SHE IS NOT ON THE PILL..YOU MUST PULL OUT..." But my protests were in vain as Greg gripped my wifes slim waist and simply drove his huge spunking cock into my prone wife from behind. Her lips were parted in a perfect 'O' as he drove into her, making the chair I was tied to rock backwards and forwards with each thust. Her thick black hair tossing against my cheeks, as I was jostled like a demented rocking horse by their love making. Then to my utter shame and embarrassment my wife suddenly moaned loudly and came hard on Gregs huge cock. Her smooth legs buckling in her high heels and stockings as she shuddered in a massive orgasm. My humiliation was complete knowing I can never make her cum like that with my little cock. I always have to pull out as she is not protected and she always has to toss herself off afterwards to cum when we make love. The sight of her thrusting back against him in her binds, and cumming uncontrollably over his massive dick was too much for Greg. "I'M CUMMING TOO!!!'roared Greg as he felt her lose control. Throwing his head back he proceeded to unleash a torrent on thick white cum deep into my wifes hot fertile cunt, still spanking her smooth bum cheeks at the same time, and calling her all sorts of names. I counted over 10 thrusts as he sprayed her lush asian pussy with his hot dominant macho cream. Finally, exhausted and spent he pulled out of Dahlia, and downed his whole glass of wine.."Fuck yes that was better than anything I dreamed of" he gasped, catching his breath., Untying my wifes arms, he led her around in front of me. I could hardly bare to look at my beautiful unfaithful wife, knowing she had given such pleasure to another man, and was simply full of his macho jism. I had not been allowed to cum in her for over 6 years since she went off the pill. "Straddle your wimp husband Dahlia" he chuckled, as she stood before me. "Tell him you are my slut now..." My cheeks were glowing with shame and cuckold humiliation as she repeated his words to me...but my rock hard little dick betrayed me, straining in my flimsy peep hole panties. God what sort of a husband or a man am I? thought to myself.... As she leaned in, I felt a hot splash of Gregs spunk and her love juice, pour from her and spatter over my aching cock and balls. "now use my cum to bring your wimp husband off' Greg instructed as she wrapped her hand around my little dick cupped my balls with her other hand. As she began to gingerly wank my little cock, Gregs hot muck washed over my shaft and knob adding lubrication to my own pre-cum. It was then I felt my hair pulled back and Gregs huge cock simply sailed into my mouth. Followed quickly by another slap on the face. "SUCK COCK YOU LITTLE BITCH" greg barked. It was the final act of total submission and humiliation, being jerked off and sucking cock in front of my wife and her lover. "FUCK YES, YOU LITTLE COCK SUCKER, YOU REALLY DONT DESERVE HER...SHES MINE NOW" moaned Greg as he began to steadily fuck me in the mouth. I simply lost control, and sent a torrent of sissy spunk arching high into the air, at his cruel words. At the same time Dahlia was tugging hard on my tightly packed little balls and digging her long red finger nails into them, squeezing every drop of my sissy jism from them My cheeks bulged with cock as he rammed my head up and down his thick shaft. I could see the disdainful look in my wifes asian eyes as Greg held the back of my head and shoved his cock right down my throat. I swallowed desperately as he unloaded into me, the rest of his spunk jetting out the sides of my mouth and spattering over my cock as she continued to toss me off... "I told you your husband prefers cock.." Greg told my wife as he withdrew. My spurting little cock was drained and exhausted but still twitching, and my head reeling at this treatment. I could only watch as Greg slipped his arms around her slim waist and kissed her deeply... Dahlia responded, slipping her tongue into his mouth and french kissing him deeply. Gregs manly arms around her and his manly chest pressed tightly against her heaving little tits. "Lets go to the master bedroom now darling...This little wimp can stay tied up down here for a few more hours" he said turning to me. "NO THIS CANT BE HAPPENING", I thought as the kitchen door closed, and I heard Dahlia's high heels clicking on the stone tiles of the hallway and stairs. Things were never going to be the same again between me and my wife.
