Neighbour part 3

During this latest bout of hot weather K messaged me and said her garden irrigation system had stopped working and would I call round when I had a spare hour or two!
I waited a couple of hours, and strolled down and was disappointed to find K in the garden, spade in hand. So, this time I was going to have to work for my reward! The fix was simple, an animal had dug up part of the system and broken a connection.
With the fix in place we retired to the terrace for a beer. Sat under the large umbrella we chatted as neighbours do. It didn't take long for the conversation to get round to 'have you had sex outside'! We both had and K quite regularly, as a youngster. Seems she enjoyed the attention of her stable hands!
The terrace is hidden from public view, sunk down so even if someone did walk around to the rear of the house you wouldn't see anyone. K kept her side gate locked so there was no way of anyone sneaking up and catching us.
We exchanged our experiences, K was a wild teenager by the sounds of things, telling me how she'd let the stable lads to finger her, she didn't stop as she entered her 20's but now it had become a quick fuck. She told me she loved it from behind, bent over a rail in the stable and once three lads took her one after the other. Filled her full of cum, she went home dripping.
I was rock hard, already sweating but could feel the temperature rising. K could see I was turned on, she stood, dropped her shorts and knickers, bent over the table and said 'just fuck me, hard and fast, cum quickly'. She was a bit dry at first, so I took my time initially but once she'd become wet I went for it. I was deep inside her, in out as quick as I could. My balls swinging, the sounds of our body's hitting each other, her wetness increasing. It didn't take long, a couple of minutes at most, but when I came, it was huge. I pushed my cock as far in as I could, stood behind her enjoying the moment. K was panting hard, I was dripping wet with sweat, I stayed still and K reached underneath cupped my balls and said 'don't move, you'll be hard again in a couple of minutes, play with my tits'. We stayed like this, my balls in her hand and being gently squeezed for a little while. K started to rock slowly, working on my growing cock. She was squeezing it while I was inside her, must be the horse riding that allowed her to do this. I was hard again.
This time I took it slow. Enjoying the feeling of being inside this horny 73 year old. She was wanting it faster, harder, wanting to cum with me. I speed up, pushing deep inside her. She started to move with me, told me to push my cock in as far as it would go and keep it there. She took over, moving to find the best place for her, she found it and told me to finish her off, she was ready. I sped up, did something I've never done before, slapped her bum, kept pounding, she wanted more, more cock, more slapping. She was doing dirty talk, "fuck my pussy, fill me with your cum, yes, yes smack my arse, harder harder, fuck yes this is it, oh god, fuck me, fuck me harder'. I was banging away as hard as I could, smacking a red bum cheek, then she had a massive orgasm. She literally screamed 'oh fuck me, keep going, keep fucking going'. I did, banging a way, dripping in sweat and then we came together. She shuddered, twitched and fell on to the table. I stayed still for a little while, my cock slipping out of her, my warm cum following. I put two fingers inside her, filled my hand with as much of my cum as I could and let her lick my fingers. I knelt and licked her arse. Rubbed my tongue around her bum hole, she shuddered again, cumming a third time. I was exhausted, spent. So was K.
We sat for a few minutes, getting our breath back, naked from the waist down. K got two more beers, and we sat in silence drinking them half naked, cum dripping from K. We didn't need to say anything, we knew we'd just had the best sex we'd had for ages.
