Karla and I had been married for about 5 years when we moved from our sleepy home town to the state capital. A promotion at work had forced us to move and Karla to leave her job, both of which pleased her. At 25 Karla was keen to experience life in a big city and she was more than happy to have some time off work to explore the "Big Smoke".
About 2 weeks after our arrival Karla told me that she had joined one of the local gyms and had run into James, one of our next door neighbours, there and that she had arranged to train with him on a regular basis. This didn't surprise me as Karla is a gym nut and often trained with men as she claimed other women didn't train hard enough. Karla's 5'11" lean, well muscled physique often intimidated men let alone other girls. Infact Karla was easily bigger and stronger than me, something my mates constantly teased me about, telling me that she was too much woman for a wimp like me. I knew James, who is 6'5"and 250 lbs of ripped muscle, would more than keep up with her in the gym.
Karla, now with a lot more free time, soon found herself training every day and this led to her physique and strength improving even more. When James couldn't keep training everyday she began training with a few of the other boys from next door. I spoke to the boys next door all the time and new they would be able to put her through her paces in the gym as they were all very strong and muscular looking, not one under 6 foot and 230 pounds.
As Karla's strength and size increased so did her libido, she would come home from the gym and demand sex almost every day. This was surprising as we normally only had sex once or twice a week.
While in bed one night, about 6 months after our arrival, Karla broached the subject of threesomes and the possibility of us having one.
"But I thought you hated the idea of being with another girl?"
"I do, I want one with another man" she said.
"You What! Aren't I satisfying you?" I demanded.
"Well actually baby I've been wanting more lately, it's not that you’re not good. I just want something extra" she said calmly.
"Extra what?" I yelled, felling somewhat hurt.
"Don't be angry with me, I'm just being honest. I'm more of a man than you are, so what I want is a real man. I don't want to break up, I just want to get taken by a real man for change. Someone who will dominate me and give the good hard fucking I need" she stated.
I was absolutely shocked at what I had heard and was devastated to hear I wasn't as good as I thought I was, so I spitefully yelled "like those bastards you train with, why don't you just go next door now and stay there!!!"
"Now look here, I'm going to be getting what I want so you can either deal with it or leave. I said I don't want to break up and I meant it, the ball is in your court" and with that she rolled over and went to sleep leaving me to make my decision.
During a night of little sleep I came to the realisation that I loved Karla too much to let anything get in the way, even her having sex with other men.
At around 6am I woke her to tell her, reluctantly, that I was fine with her decision and ask her when she intended to start and with whom.
"I'm glad you've come around baby, I want let it come between us I promise. As for whom, definitely James, he's such a stud, and then the boys next door to start with"
"To start with" I interrupted "and the boy's, how big is this going to get?" I asked, more than a little concerned.
"I have been craving variety for a while now baby and you know I don't do anything by halves. But don't worry it'll be fine, I promise."
"Well if you say so. When do you plan to start?"
"Today, but I want him to initiate it. I think today I'll switch from my normal baggy gym gear to something that will hopefully hint at what I'm after. I might even try to make him wait for a while, but I doubt it. I do want him very badly" she explained.
"Oh, and baby, I'm going out shopping for some new gym gear this morning. I think you should come".
Three hours later we returned home with Karla's new gym outfit. My wife, who normally works out in old track pants and a t-shirt, had purchased the smallest black lycra hot pants and bra top I'd ever seen.
"Won’t you look like a slut parading around the gym in that?" I asked when she tried it on at home. The black contrasting nicely with her milky white skin.
"Hopefully" she said, "plus all the aerobics girls wear outfits like this, some even more revealing than this" she explained.
That last comment I found hard to believe as this out fit showed my wife’s amazingly muscular figure off like nothing I'd ever seen. You could see every rippling muscle and along with her C cup breasts, which were now on public display, she looked like an Amazon warrior. If these boys didn't go for this then there was nothing they would go for.
"Bye babe, don't wait up, I might be late. Hopefully" she said, walking out the door in her normal gym attire which she had put on over her new out fit.
Karla's workouts normally lasted about 2 hours but it was around 8 hours later at 12 midnight by the time I heard her car pull in. I was feeling both very worried about how this would effect us and also, for the first time, a little excited about her having sex with someone else. Especially the big young black stud from next door.
"So what happened" I demanded as she walked in the door, looking very dishelved and starry eyed.
"Well wouldn't you like to know" she said, pointing to my bulging crotch.
"Oh, sorry, please tell me. I'm dying to know" I begged, trying to cover up and realising I had not noticed getting hard thinking about her with someone else.
"Well sit down, shut up and listen, I've got to leave again in minute so I'll have to be quick." she explained. My beautiful blonde wife then talked on very excitedly.
