My gym closed down last week after giving us three days' notice. We were given no reason for the closure, but I had to search for a new gym.

For the past fifteen months, I had been training hard five days a week to lose weight and to get some fitness at the ripe old age of sixty-three.

In those fifteen months, I lost four stones and have regained some fitness. I can now run and keep up with my grandchildren, well sort of.

I attended an induction with the lovely Lucy, I was shown around and given a workout program that suited my needs.

While at the gym that day I spotted a gorgeous lady walking up the stairs to the upper floor as I descended to the lower floor. Our eyes met and there was an instant recognition of one another.

All I could think about was wow this lady is stunning, she was slim, very slim but had a great pair of boobs and was so pretty. She had short blonde hair and was wearing a tight black vest and leggings that accentuated her amazing figure.

As we passed my eyes followed her and hers followed me then we spoke when we both realized we knew one another.

I said, "Jo, that is you, isn't it?"

She replied, "Yes, I can't remember your name but you're Emma's dad aren't you."

I replied, "Yep, it's Dave."

"Of course," she replied.

The last time I saw Jo she was carrying a bit more weight and her legs were really chunky, but now they were long and slender and she was super fit. Actually, when I see Jo she is normally wrapped up for winter, watching her son and my grandson play football on a Saturday morning during autumn and winter.

It was clear to me Jo was not wearing a bra, she didn't need one, her fabulous boobs were so firm and perky and her nipples were large and stubby.

Having passed on the stairs and said our hello's we both moved on and continued our workouts, but by chance finished at the same time.

I had showered and changed by the time we met in the reception where we spoke again, we chatted briefly and I said, " Do you fancy a coffee?"

To my surprise, she said, "Yes, I would love to, but I have to wait for a plumber to arrive, so why not come back to my house."

Jo explained that she had a water leak in her kitchen, and because James her husband was away she had called a plumber who was due to arrive that afternoon.

I followed Jo to her house and parked a few doors away, Jo then let me in and we made our way into her kitchen where Jo made us a coffee.

We were sitting at her breakfast bar drinking our coffee when Jo said, "Would you mind if I took a shower? If the plumber comes can you let him in?"

Jo showed me where the leak was so if the plumber arrived I could show him what needed to be fixed. Jo then went off and had a shower.

Jo returned about twenty minutes later, she had changed into a tight-fitting white v-neck t-shirt and a denim mini-skirt. She clearly had no bra on and the outline of her nipples was clear to see, and the t-shirt showed off her deep cleavage.

She looked irate and upset, so I thought I had outstayed my welcome and got up to leave.

I said, "Thanks for the coffee, I think I better leave, you look really upset so I will be off."

Jo replied, "It's not you, it's the plumber he has been delayed, he said he cannot come for another few days as he is fully booked."

I said, "Would you mind if I took a look at the problem?"

Jo replied, "That would be great, James has some tools in the garage if it is something you could fix."

I had a quick look under the kitchen sink and found the problem, I straightaway realized it was just a matter of retightening a couple of joints.

Jo brought me a bag of spanners from the garage, I turned the water off and lay on the floor with my head and shoulders in the cupboard.

I loosened the joints off cleaned them up, then went about reconnecting them.

At this time, I looked up and found that Jo was standing astride me, and I could see straight up her tiny mini skirt. Jo was only wearing a tiny white thong beneath her skirt and her shaven pussy was clearly visible through the thin material.

I could not believe my eyes. I was less than three feet away from her perfect little pussy. I started to sweat and my cock started to swell in my tight lycra cycling shorts.

I went back to the job in hand, taking an occasional glance up at Jo's pussy which now seemed to be glistening with her juices.

I knew my cock was a problem as I am very well-endowed, and I was sure it was now fully erect in my shorts, I was just hoping Jo hadn't noticed.

I was just finishing off and tightening the last joint when I felt a hand on my cock, "Wow!" I said, "Sorry about him, but he has a mind of his own." Jo bent down and looked at me in the cupboard.

I said, "Can you turn the water on so I can check for leaks."

Stupid thing to say, I know, but I didn't know what else to say.

Jo turned the water on and I checked the results and confirmed that all was well and the leak was cured.

I was still lying on my back with my head and shoulders in the cupboard making sure everything else was good when I felt Jo tug at my shorts and release my cock.

I said, "What are you doing?" as she took my erect circumcised cock in her hands and knelt between my legs.

Jo said, "I am just showing you how grateful I am."

Jo completely removed my shorts and allowed me to extract myself from the cupboard so I was much more comfortable.

Jo said, "I have never seen a circumcised cock before, and never seen a cock so big and fat."

Jo was still rubbing my cock giving me a gentle wank, I was just in heaven but feeling very uncomfortable with the situation.

I need not have worried as Jo lowered her mouth over my cock and took as much of it in her mouth as she could. She slowly started to bob up and down on my length while one hand continued to wank me and caress my balls.

I tried to reach out and take her breasts in my hands but was given that look that meant NO. But to my surprise, she removed her t-shirt to allow me full access to her perfect c-cup firm breasts and resumed giving me a blowjob.

I caressed her breasts as she slowly brought me to the point of no return, I could not hold on and shot stream after stream of hot cum deep into her throat. Jo swallowed as much as she could and then took the rest over her naked breasts before cleaning me up with her mouth and tongue.

Jo could see that my cock was not going to subside anytime soon as I lay on her kitchen floor with my cock still pointing up at the ceiling.

Jo to my surprise pulled her G-string to one side and lowered her soaking wet pussy down onto my erection. Jo started off slowly and built up a good speed riding me like a woman possessed.

She had at least two orgasms whilst in this position, Jo was complaining that her legs were aching and started to slow down almost stopping to have a rest.

I took control and lifted her off my cock as we both stood up, I positioned her over her kitchen sink so she was looking out of the window into her rear yard. I stood behind her and after ripping off her g-string I eased my cock deep into her pussy from behind.

She writhed and wiggled as I fucked her long and hard holding onto her perfect breasts and I gave her two further orgasms before dumping my load inside her.

We were both completely exhausted and sweating like pigs as we broke away from one another and collapsed onto the bar stools.

Jo slipped her t-shirt on and I my shorts in case we had any visitor call.

We talked about what had just happened and neither of us really knew how and why it did, but were both okay with it and agreed it shouldn't have and probably wouldn't again.

Before I left Jo said, "If ever I need a plumber again I will give you a call."

I said, "See you at the gym tomorrow," and left.
