For as long as I can remember I've been fascinated with MMF threesomes. I'm 100% straight, and I've never had any desire to share my own girlfriends with another man, but the thought of being that third party has always appealed to me. I started to find myself seeking out MMF porn, especially amateur/homemade stuff, and if it was obvious that it was a married couple with a friend, all the better. I even found myself in a couple of MMF situations, but only with mutual friends or fuck buddies. They were fun, but they didn't hold the same allure. Don't get me wrong, I'm no "bull" and I don't get a kick from humiliation or "cuckolding", I'm just fascinated - and aroused - by the thought of loving couples inviting another man into their bedrooms. A couple of years ago, my obsession got the better of me and I started to answer adverts placed by couples on SH. A lot seemed to be placed by guys hoping to convince their wives to give it a go and consequently, didn't amount to anything. A couple of others were simply looking for someone to entertain the wife alone, which was a great way to test the water and enjoy some great sexual encounters, but what aroused me most was discussing and planning the encounters with the other guy, talking about how he'd like the evening to unfold - what his wife enjoyed most. Then a few months ago I received a response from a couple called Mike and Emma. Mike was older (mid forties) whilst Emma was 25, and Mike told me in his email that it would be their first threesome; that I was exactly what they'd been looking for; and that for a long time he'd fantasised about watching someone else "making love to his angel". Mike was quite open about the fact that he was bi-curious, but only orally and that it wasn't an issue if I was straight. The only other caveat was that Emma wouldn't perform oral sex, even though she was happy to receive (I bet she was!). They'd decided that this was something they'd like to save for themselves. To be honest, this was quite a big disappointment - oral sex is a very important part of foreplay for me, and even more so in this situation - the thought of a guy watching while his wife performs this most intimate of acts was a massive part of the turn on! Over the course of a few weeks pictures were exchanged, getting progressively more risqué, culminating in some coy naked shots of Emma. She looked lovely, a petit brunette with a girl-next-door smile and a twinkle in her eye. She had small tits with tiny nipples and flawless white skin. Her arse looked perfect and I wasted days wondering what the rest of her looked like! We arranged to meet three weekends later as they were going on holiday - I joked with Mike that they'd have a fantastic time fantasising about their first meet and discussing how it would pan out. After three weeks I was chomping at the bit. I'd thought of nothing except meeting them, and seducing Emma in front of Mike - I was "cracking one off" several times a day, my poor cock didn't know what had hit it! Then the message came through: "Are we still on for Saturday?" I replied to Mike's text as quickly as my thumbs would allow "Yes, just tell me the time and place...", and then nothing... No reply... I checked that the text had gone through - it had. I sent it again, that one was delivered too. But still no reply. I emailed, saying I'd sent a text but not had a reply. Nothing. I was gutted, another time waster. Oh well, I'd had a few weeks of great wanks and fantasies, but I was disappointed I wouldn't get to see the look on Mike's face as I fucked his angel before his eyes. A few weeks later, I'd all but forgotten about Mike and Emma when I got an email out of the blue: "sorry mate, Emma started to have second thoughts, didn't want to mess you about etc". I replied as politely as I could manage, offered to help in any way I could, but I was resigned to the fact that it was just pleasantries. "There is something you can do, if you don't mind" came the reply, "can you add us both on Facebook... Let her have a look at your profile, get to know you a bit... I think it might help". Well, I didn't have anything to lose, and it meant I could have a good nosey at pictures of them - if nothing else it would make my fantasies more real. So I sent the requests. Later that evening they both accepted at the same time - I fantasised about the pair of them at home, pouring through my photos and discussing me, maybe discussing having sex with me before shagging like a couple of horny rabbits! The following morning I woke to a 2-word text message: "It's on :o)". I replied "No problem... But I expect a BJ for all this messing about... Off Emma, not you!" We arranged that we'd meet at the pub at the end of their road for a drink, and if we all got along, we'd head back to theirs for a bottle of wine and see what happened. The evening arrived and we met as arranged, I don't know who was more nervous, but we soon broke the ice chatting about holiday photos we'd shared on Facebook. Mike seemed genuinely excited at the prospect of seeing his angel getting fucked by another guy, and whilst she was obviously nervous, she had that glazed look of someone who's as horny as hell! Back at the house, Emma and I sat on one edge of a corner sofa while Mike went to open the wine leaving us alone for the first time. "Are you sure you want to do this?" I asked, "Hell yeah!" she replied before launching her face at mine and giving me a long, lingering French kiss. "Ah, I see you're getting on OK..." Mike stood in the doorway looking a little awkward holding a bottle of white in one hand and three glasses in the other. Emma shot him a wicked, horny smile before resuming her kiss, her hand rubbing my cock through my now straining jeans and clawing at my belt buckle. I helped her undo the belt and ripped the button flies apart allowing her to slide her hand down and lift out my cock and balls. Mike was now sitting on the other side of the sofa, watching intently as his young wife slid her leggings off, hoisted her jumper over her head and straddled me in just a lacy pink bra and thong. I lifted my hips as she wriggled my jeans down. She glanced back over her shoulder and both she and Mike nodded. She knelt over to the other side of me, cupped my cock and balls in both hands and lowered her face towards my shining bellend. I was now sitting practically facing Mike, with Emma - face inches from my cock - in between us. They shared a long look, her face was hidden to me, but Mike's eyes flashed with a mixture jealousy, anger and extreme arousal. I could see his erection growing as she opened her mouth and gently slid her lips down to the base of my cock. Mike looked like he was either going to explode with sexual ecstasy or attack me! The atmosphere crackled with the electricity of sexual tension, Emma's short, shallow breaths betraying her nervousness and arousal. After a few minutes, I started to feel that familiar tingling as an orgasm began to swell, so I stopped Emma and kissed her deeply, the salty taste of my precum on her lips. I lowered her onto her back, her head resting on Mike's lap and gently lowered her thong - a silvery thread of her own wetness traced a line between her underwear and her puffy pink lips. She drew her knees to her chest as I slipped her thong over her feet and I caught a glimpse of her perfect little arse, a completely hairless pink pucker. I thrust my head down and gave a full lick from arsehole to clit before plunging my tongue between her lips and tasting her sweet wet pussy. I looked up to see her, biting her lip and looking lovingly into Mike's eyes. Mike was bright red, again, a mixture of lust and jealousy at the sight of my tongue ploughing apart his angel's pussy lips. After a few minutes I knelt up, took Emma's hand and placed it on her pussy. She started rubbing her clit as I reached behind me to get a condom out of my jeans. When I turned back, her hand had been replaced my Mike's, and her wet finger was encircling that gorgeous little butthole. I rolled on the Durex but lowered my head for a final lick, my tongue taking the place of her finger and lapping away at her arse while Mike strummed her clit with one hand and tweaked her nipple with the other, Emma's head lolling about in sexual delirium. I plunged my cock deep into her as Mike held onto her shoulders, nervously smoothing her hair which was now sticking to her forehead with a film of perspiration. Within seconds she started to buck and quiver as a massive orgasm built within her, her breathing getting faster and faster as she screamed that she was cumming. The moment I felt her lips contract around my cock, I withdrew and placed my mouth over her clit, slipped 2 fingers into her sopping pussy and the middle finger of my other hand gently up her arse. She recoiled at first and I remembered their "no anal" rule, but she was soon grinding down onto all my fingers, bucking and squirming as her orgasm overwhelmed her. I sat back and watched as her convulsions subsided, a bead of sweat running between her tits and settling in one of the undulations of her slight six-pack. She looked amazing. Mike had a huge wet patch on his groin - khaki chinos weren't such a good idea! After a few moments, Emma sat up, grabbed my cock and ripped the condom off before getting to work with the most energetic, rasping blowjob I've ever had. She paused briefly, turned to Mike and beckoned to him, patting the carpet at her side. Mike knelt down next to her and watched, his face just inches away while his wife expertly sucked my cock. I have to admit, this felt kinda weird, but I just needed to empty my load so I went along with it. But nothing could prepare me for what happened next: she reached back and put her hand behind Mike's head before guiding him towards my cock which she was holding with her other hand. We both froze for what seemed like an eternity, my cock deep in his mouth, his lips clamped tightly round my shaft. Then I felt his tongue flicking around my bellend, as if tasting me. After a minute or so Emma started guiding his head back and forth, his hot breath forced from his nostrils with each stroke. I didn't know what to think, I'd never so much as touched another guy in a sexual way, and here I was having another man sucking my cock. It felt OK (in a weird way) but the look on Emma's face turned me on in a way I've never felt before. After another couple of minutes, she leaned forward and joined in, their tongues flicking around my cock and balls, my bellend disappearing into each of their mouths in turn. "I want Emma to make me cum", I said, and then realised how strange that must have sounded! She looked up and smiled as best she could with a mouth full of my cock and upped the pace, taking me to the point of no return. I came like I've never cum before, the first jet covering her cheek and eye, subsequent jets shooting into her mouth as she took my full length back down her throat. Mike watched her, enraptured as she slowed right down in perfect tune with my subsiding orgasm, rolling my cock round in the mouth before kissing it gently on the end and catching a small drop of cum on her tongue. She smiled at me before turning to Mike and giving me the horniest sight of my life - she leant forward and kissed him deeply and passionately, my cum smearing across their faces. Emma was still holding my softening cock, but they seemed oblivious to me as they practically devoured each other. I sat back and enjoyed the show, an indescribably feeling of pride, pleasure and satisfaction coursing through my veins...
