I went down the gym early as I couldn’t sleep, and when I got there is was empty except for one other guy. While I was on the rowing machine the owner (49) walked in, and came up to me and whispered, “ I hear you had sex with my wife Petra in the showers, are you into having fun with the husbands as well.”

So I looked at him and said laughingly, “ you never know your luck,” and he smiled and walked away, and I carried on with my workout. The other guy left and I just had my biceps to work on, so I went over to the bicep curl machine, and the manager came back into the gym, and stood there watching me.

The next thing I knew he was behind me offering to give some advice on how to get the best results out of the machine, and as he was helping me his hands brushed my nipples, through my Lycra top, making me shudder, and he said, “ sorry, but I must say you have lovely firm nipples.”

I just smiled, and gave him the benefit of the doubt, that it had been an accident, then I felt him lean into me, and I could feel his hard cock against my ass. Then when we finished, he informed me the women's showers were out of commission, and he said I could use the shower in the guys locker room.

I looked at him with some doubt after what had been happening, but he quickly added that it would be ok, as there was only one other people in the gym and she was the cleaner. He then said he would be sure no other guys came in, and I got the feeling I was being set up, but thought his cock did feel good pressed against my ass, so I grabbed my bag and went into the guys locker room.

When I went in, I saw that the men's showers were a communal shower, like in the women's locker room, and I thought well it's ok, I'm the only one in here. So I took off my clothes, and put them on a bench and walked to the shower, and I rinsed myself off and started shampooing my hair.

After I got my hair really lathered up, I heard another shower head turn on, and my first reaction was to shield my body somehow, but I am not ashamed of my body, I’m kind of proud of my body and don’t mind showing it off, so I didn’t? but I couldn’t see if anyone was there, but my curiosity got the best of me and I washed the soap from my eyes enough to see who it was.

It was the gym owner, and he was totally naked and shampooing his hair too, and I thought what the hell, then I looked down and noticed the size of his cock. And holy shit he was flaccid and about 5 inches, its the first time anyone has measured up to my boyfriend, and I don’t know why but I was mesmerised, and I couldn't help but looking at it.

Then I realised we are both naked in this shower alone, and I still had to wash the soap out of my hair and I hadn't really bathed either, so I may as well continue. He finally washed the soap from his head, and he glanced over, really studying my naked body, and said like everything was normal, "That was a good workout, wasn't it?"

So I turned my head and faced the wall, so only my ass was visible to him and said, "Yes it was." Then he said, "You are doing really well, I think next time you should kick it up a notch." I couldn’t get his cock out of my mind, and I peered over my shoulder, and my eyes, if working on their own, traveled back down to his cock. And he said, "Well, what do you think?"

I replied, "Think?" and I looked up to his eyes. "Think about what?" And he said, "Kicking it up a notch. You know, next time really pushing it. I mean you've already got a great body, but I think you can sculpt it a bit.” For some reason I felt at ease, chatting to him while we were both naked showering, especially as I’d had sex with his wife.

We were both naked in the shower so everything has already been seen at this point, and I could not help but look at his cock again. He even caught me looking once or twice, but was kind enough to pretend he hadn’t, or so I thought, when he said, “I know you enjoyed your shower with Petra, she told me all about it,” and I could now see his cock twitching a bit as we spoke.

I finally finished showering and made my way over to my clothes, and was drying myself, when he came over to the next bench and was drying himself off. He put one foot on that bench and was drying his hair when I looked up and saw his large cock dangling between his legs right at eye level. And I immediately felt a tingle between my thighs, and my pussy getting wet, as he said, "You haven't seen one that large before, have you?"

"What?", I said as I looked up to meet his eyes, " yes my boyfriend, ask your wife,” laughing and then out of instinct, I looked back down at it. And he was now nearly fully hard, and immediately knew he was on par with my boyfriend, but his was a lot thinner than my boyfriend, and I said,” for fucks sake, I know what you want, just fuck me,” so he told me to bend over the bench, and started rubbing his cock.

"It's ok," I said, “ come on just fuck me,” so he slid his cock between my ass cheeks and into my pussy, and grabbed my hips and immediately started to pump in and out of my pussy. Then he bent right over my back, and brought his hands around to my tits, rubbing them and tweaking my nipples, whilst he pumped his cock in and out of my pussy.

After about 5 minutes or so, he said, “ I have to say, yours is the first black cunt I’ve had, and my god it feels so good,” as he started to shoot his cum deep into my pussy, then when he finished cummin, he went soft quite quickly, and pulled out of me. Then left me to clean myself up and get dressed, then as I got back to reception, he said, "Ok, have a good day, see you next time." as I left, like nothing had happened.
