Married life brought a real lull to our sex life to the point where it seemed that my wife was doing it as a chore rather than with any passion. This made me feel inadequate as well as restless. I knew that I was a good lover and unselfish and my thick 8" cock was still performing well. My restlessness was making a strange part of me itch, namely my unexplored bisexual side. I had never really been attracted to men but the thought of a nice, hard, hot cock in my mouth made me hard and the thought of that cock pounding me hard up the arse set me alight and I would have to find somewhere to have a wank, either in the shower at home or the bathroom at work. I even had to use the toilets on the train one time.
I tried bringing up exploring some fantasies with my wife, mainly her own but she just would not speak about it. She had no spark any more and was letting herself go. Something drastic needed to happen. I encouraged her to start getting some exercise and to let our son be looked after for a couple of days a week so she could get some time to herself to go to the gym and the beautician. Within a couple of months, she had firmed up and her skin was radiant. Luckily for me her D-cup boobs stayed where they were. Her personal trainer Anthony was a boob man like me and he tailored her exercise so that it toned up her tummy, thighs and butt while improving her aerobic fitness.
So there she was, back to being a size 10 but now with a D-cup rather than the B-cup when we first met. She started spending more time with her gym friends which was good for me as I got to work on my PC at home and watch heaps of YouPorn clips. We also started making love a bit more regularly, every other week or so but they weren't the roll-on/roll-off affairs of months gone by. We actually would go for an hour of so and usually have 3 or 4 fucks during that. It twigged that she had been fucking someone else when she did something that she had never done before and would only have seen it a porno or been taught it by a lover. I had asked if I could cum on her tits and she was surprisingly happy to do it. I would usually just straddle her while she lay there and shoot over her luscious mounds but this time she got off the bed and knelt on the floor and pulled me by the cock towards her. She started stroking my cock while pointing it at her tits (first indicator) and then as I was about to come, she took her fingers away from her pussy (second indicator, she NEVER played with herself) and slowly slid a finger up my bum as I started to shoot a massive load. My sphincter contracted around her finger and I just about passed out from the pleasure and shock of my wife being into it when I came on her tits and playing with her clit and slipping a finger up my arse while I came.
After cleaning up a bit and having a cuddle I decided to broach the subject. "Honey, what was that about?"
"What was what about?" she asked, trying to act as if nothing was wrong.
"Babe, I've never seen you happy about me coming anywhere but your pussy before, you have never touched your pussy while in my presence before and you have NEVER played with my bum before. Lots of new tricks for someone who doesn't watch porn" I said, smiling at her. "If you are fucking someone else, tell me about it. I want to share and hopefully get your mojo back. So long as I am involved and this doesn't affect our marriage, I am cool with it if you tell me."
She bit her lip and tried to stammer out a fabrication. I told her it was lies and that I wanted the truth. She looked down at her feet and started to tell me about the affair with her trainer Anthony. He got hands-on with her training from the first day, helping her to do sit-ups properly and spotting her while she did weights. He would wear loose shorts and no undies and stand over her so she could see his cock while she did fly curls and bench press.
"So tell me about his cock," I said, with my cock getting bigger with every detail.
"Its not as thick as yours but a bit longer and rather flexible, just like him really. We seem to get into some weird positions" she giggled. I asked her if all of her "coffee with the gym girls" was really the affair. She said yes but that it was more fuck sessions at the gym with Anthony and some gym friends. I asked which gym friends and she hesitated.
"Davis and Antoine," she said. I was amazed as these guys were both gay. They were also black and had the look of Greek gods. My cock was massive by this stage and needed some more attention. I rubbed my hand against my wife's cum-filled pussy and started jerking off with the cum and pussy mixture. My wife smiled and moved down to take my cock in her mouth and gave me the first real blowjob I had gotten since before we were married. I came in her mouth and fell asleep with a thousand horny thoughts in my head. I woke up before my wife and decided to treat her by sucking her nipples to wake her up and then licked her pussy till she raised her hips up off the bed and screamed through her orgasm. We talked about her sex sessions with the guys at the gym and she said that Anthony was a very persuasive guy and he made her feel very sexy. Davis and Antoine were always training nearby and enjoyed watching Susanne's transformation. They had been friendly when she started and became fans of her hourglass when she started getting toned. The sessions began when Anthony snuck Susanne into the men's showers and fucked her with the guys watching and jerking each other off. This changed to Susanne being fucked by Anthony and sucking Davis and Antoine's cocks. Davis and Antoine began fucking her too while Anthony watched and they all thought it was a good way to strengthen core muscles.
I wanted to be a part of this but Susanne was not sure. I said that the alternative was not fucking them anymore and she said she would talk to Anthony. I decided to contact Davis and Antoine myself and they were wary for a while but I assured them that I was not after revenge but to be part of a hot sexual experience, especially with a couple of well-hung good-looking black men. They got the idea and were only too happy to make it happen. To get ready for the night I went to a place on Oxford St that specialised in the male version of the Brazilian. I am naturally pretty smooth and the guy who did the waxing for me paid particular attention to my crack and rubbed his cock on my arm so I decided to return the favour and started to rub his cock through his trousers. I shuffled up to the end of the massage bed and leant my head back so my throat was open and let him stick his cock as far into my mouth as he could. I got my first mouthful of cum not too long after this and a promise of more free waxing if I wanted to play again.
There was a long weekend coming up at the gym that the guys went to and Antoine had talked the owner into letting him close up for the weekend. Susanne and I got to the gym at 9pm, after everyone had left and met up with Davis, Antoine and Anthony in the weight room. They were all buff from their workout and looked amazing. I told Susanne to get into her gym gear and show me and the guys how buff she was. She giggled and stripped off to her sports bra and short shorts and started her workout by doing some squats. Her arse looked fantastic as she moved and her boobs were great when she strained on the way up.
