Paul, my husband, had just gone to work, and I had the day to myself. I tidied the breakfast stuff in the kitchen, loaded the dirties into the dishwasher and put the cereal back in the cupboard and the loaf back in the bread bin. Time for a little me time. First a shower. Paul and I had shaged last night, and I was a little wet down there, and I needed to clean myself out, remove his residue before it started to take on an odour.
In my bedroom I put my dressing gown back on the hook on the back of the door and put my hair up with a scrunchie. I didn’t want to get it wet, it didn’t need a wash, and I didn’t need to spend an hour drying and shaping it. Into the ensuite, shower on, a quick inspection in the mirror, the shower cap on, and I was under the flow. Oh, I love the feel of the needle jets of water in the morning – so invigorating. In the evening I prefer the rainfall setting, which is more relaxing.
I took the hose from its clip and aimed it up at my fanny, using my other hand to hold myself open as much as I could; the feel of the water shooting inside me was quite pleasant, to say the least. After a few minutes of douching, I felt clean inside and turned to the rest of me. I put the hose back on the clip and rubbed myself with gel and then scrunchied until my skin tingled. Back under the water to rinse off, and I was done.
I stood dripping dry as I cleaned my teeth, then took the shower cap off and let my hair down, running my brush through it; the damp atmosphere would help give it body, done. I applied a little lipstick as a moisturiser as much as anything, but I didn’t put any other makeup on; I wasn’t going to do it, it wouldn’t be necessary.
I put on my day robe, a simple cover that was slightly sheer and light but kept me decent enough if I passed a window and someone just happened to look in, or if someone came to the door. Brief encounters decent; longer-term perhaps not. I gathered the laundry from the hamper and went downstairs. I dropped the laundry in front of the washing machine and put a cup under the espresso machine.
I topped up the water tank and pressed the button. I planned to sit in the conservatory and enjoy a coffee, sitting, sipping just a little at a time, savouring the aroma as well as the taste. The grinder ground the coffee, and then the pressurised water started, the aroma beginning to percolate through the kitchen. I smiled; the association of the aroma and the prospect of sitting in the conservatory gave me pleasure.
I loaded the machine, added the washing sheet and set the programme, and off it went. I grabbed my coffee and went to sit in the conservatory. The sun hadn’t quite got it too hot yet, so I kept the door closed. Another hour, and I would be opening the door to regulate the heat. I planned to spend a few hours in there, at least until the laundry was done and I had to put it on the line to dry.
My doorbell rang, and then I heard my door open and someone walk in. What?
“Only me,” I heard. It was Dmitri, my brother-in-law.
“I’m in the conservatory,” I shouted, wondering what he was doing coming here.
“I’ll just use the loo first if that is okay,” he called back.
“Of course.” Well, I was hardly going to say no, was I?
He seemed to be ages in the loo, and eventually I heard the door open and he came out. Would I end up having to deep clean the loo? I wondered. Dmitri came into the conservatory; he seemed to be limping and a little red-faced. He sat on the cane sofa opposite me.
“Sorry, Mica,” he said as he sat down, “I had a bit of an emergency.”
“Oh Lord, upset tummy?” I asked, thinking I was definitely going to be cleaning the loo.
“Oh God, no, nothing like that.” He didn’t explain further, and I had no clue what the problem could be.
“Would you like a coffee? I have just made one; I can easily do you one.”
“Yes please,” he replied. As I got up to go and make his coffee, my eyes naturally glanced over his body; his trousers did seem to be more bulging than I would expect. I shut my eyes and looked away and went and put another cup under the nozzles and pressed the button. I mean, a man has a bulge there; that is normal, but that did seem a little, well, pointy.
I steamed some milk and took his coffee back to him and passed it to his waiting hands, my eyes once more drawn. Yes, that was a one hundred per cent stiffy happening. Oh, Dmitri, really?
“So, how are things? How is Nat?” Nat is my younger sister, Natalia; she married Dmitri last year, and so far, there are no nieces or nephews. Early days I supposed, although Paul and I hadn’t yet begun to produce, we had that planned for next year, so there was no hurry. Our brother Rogernid already had two girls, Sofiya, aged 1, and Mariya, aged 2. That was fine; I expected that they would have at least one more. I knew Mik wanted a son.
“Oh, she is great at work, as you would expect. I am not in today, luckily, and had just been going to the supermarket. Nat had asked me to get a few things, but, well, I had my issue.”
“Your issue meant you urgently needed my loo?”
“Yes.”
“And did your emergency use of my loo help?”
His face reddened, and he looked down before answering. “No, not really.”
“Oh dear, is there anything I can do to help in any way?” I wondered what his problem was.
“God,” he really looked embarrassed, “no, really, no. I’ll drink my coffee and be on my way, out from under your feet.”
“Dmitri, you are not under my feet, and you don’t have to rush, sit and enjoy your coffee.”
I smiled and then laughed. “And anyway, it doesn’t look as if you could rush anywhere,” I said, pointing at his lap.
“Oh God, is it that obvious? Oh shit.”
His face went even redder.
“I had a medical a few weeks ago, and they decided I needed a tablet to help with my heart; it is nothing serious, just a little help is all.”
“Oh crikey, I didn’t know that; Nat never said.”
“No, well, it is not serious; it is just that the tablet has a bit of a side effect.”
Ah, yes, I knew that Viagra had been developed as a heart medicine, and it was only after men started taking it that they reported its welcome side effect, especially amongst the elder men; they started getting erections again. Pfizer, the manufacturer, was quick on the uptake and started marketing it as a drug for erectile dysfunction and made millions.
“Crumbs, well, I hope that Nat is reaping the benefit; I assume she is getting shaged a lot.” I laughed again and then wondered, “Is it painful?”
“Well, yes, we do, well, you know, and it isn’t usually painful, but it came on this morning and won’t go away, and yes, it is beginning to get painful.”
“I see, so that is why you went to the loo, to try and, er, reduce the swelling.”
His face, if possible, went even redder. “Yes,” he said quietly.
“Let me go and wet a tea towel; you can wrap it around it and see if it will help reduce it.”
I got up and went to the kitchen, running the cold tap and then soaking a tea towel. I wrung most of the water out and went back to the conservatory.
“Here,” I said, “obviously you’ll have to take your trousers and pants down.”
“I can’t do that, Mica; Christ alive.”
“Of course you can; it’s just a dick, a dick in need of a cold compress. Every man has one; I have seen them before, you know.” I stood before him holding the dripping tea towel. “Don’t worry about the furniture; it is wicker, it is designed for outdoor use, and it’ll be fine.”
He moved his hands and undid his trousers and then raised his bottom up and pulled his trousers and underpants down, his dick springing up. It was a dick, a normal dick, reasonably sized, his foreskin straining back and revealing a little of his glans. It looked to be a very hard dick that was for sure.
“Do you want me to apply the towel? “ I asked rather naughtily.
“God, no,” he replied, grabbing the tea towel from me and winding it around his dick.
“God, that’s cold,” he said.
“I think that is the point. Now drink your coffee and relax; being all wound up won’t help matters.”
“I suppose not, God, I’m sorry.”
“Don’t be silly, and anyway, it is a nice-looking dick; my sister is very lucky.”
He was quiet for a moment, and then, looking at me, he said, “Thank you, and your robe is open and your fanny is equally nice looking; Paul is a lucky man.”
Oh dear, I had become inappropriate in my attire and had flashed him. I thought I had been decent, and I had not; I had shown him my everything, my everything that mattered that normally only Paul sees, and now I had shown his brother my secret place. I had a shiver of delight and naughtiness.
“Oh. Thank you, but it is just a fanny. They are all the same, you know.” I said, realising that I was getting very inappropriately wet down there.
“Oh dear, Mica, no, they are not. Natalia’s is very different; it is not neat and beautiful like yours. She has bits all jumbling out. Yours is just perfect; I envy Paul very much.”
“Oh? Why would you envy Paul?” I asked, feeling the need to squirm in my seat.
Dimitri stood up and walked over to me, bending forward, his hands on my face and his lips pressing against mine.
“Because,” he said softly into my mouth, “he has access to your beauty and your delight.”
He pulled away and stood up. The tea towel unravelled and simply hung over his hard dick. Hanging right at my eye level. His foreskin was slightly pulled back, revealing a little of his glans. His dick twitched, and I could not stop my hand from pulling the tea towel away and wrapping my fingers around.
“Oh, fuck, Mica,” Dimitri gasped as I began to push his skin backwards, revealing his glans.
“Is that what you want?” I asked quietly, “Only I am not Natalia; I am Mica, and I am not married to you.”
I began a soft wank of his dick, watching his foreskin flow over his glans and reveal his rim, and then reverse and cover it up. A small bead of white dew appeared at the hole in the end of his dick. I stopped wanking, and, using my thumb, I smeared it over his glans. It glistened in the light.
“Fuck, yes, I want you, Mica; I want to know your body.”
I let go of his dick and stood up.
“You best follow me, then,” I said, heading out and towards my stairs. As I walked, I pulled my dressing gown off and dropped it over the newel post. As I climbed the stairs, Dimitri would have an excellent view of my fanny lips sliding over each other. I wondered briefly if my fanny glistened.
“Oh, shit,” I heard Dimitri say from behind me, “your cunt is just so fuckable.”
I ignored his crudity, but I was secretly excited. I had never thought that I would affect a man other than my husband. I simply hadn’t given it a thought. Paul and I shaged just like all married couples did. It never occurred to me that I could so turn on another man. I wasn’t sure what would happen in the bedroom. I knew Dimitri would want to fuck me, but would that be it?
In the bedroom I pulled the quilt back and saw the shiny mark on the sheet that was the evidence of Paul and me shagging last night. ‘I hope it is dry,’ I thought as I turned to face Dimitri. He was completely naked. He had a light down of hair across his chest and a small paunch above his dick. From this small distance, his dick looked meaty and very hard. I wondered if the Viagra made it bigger than normal; his dick was definitely bigger than Paul’s.
I walked backwards, and when I felt the edge of the bed on my legs, I sat and scrabbled back and lay down, my legs slightly apart. Dimitri knelt on the bed and then moved my legs further apart so that he could easily kneel between them. I had assumed that he would just fuck me, and that would be that, but no, I gasped as Dimitri leant forward and blew along my crease.
My pleasures exploded; pleasures were flowing through me. I had thought that we would shag and that was it; it seemed Dimitri had other ideas. I gulped as his tongue slipped between my lips and pressed into my valley, my inner lips flowing around his hot tongue as it moved. I pressed my head back into the mattress and closed my eyes; I wanted to revel in the difference a new lover could make.
I felt a finger teasing my lips apart and then circling my fanny, each circle pressing in a little deeper until I felt a knuckle push inside me, and then another finger. Deeper and deeper the fingers pressed, and then they parted, widening my fanny. I gasped and then gulped as his tongue found my nubbin and pressed it. My fingers were scrunching, pulling at the bed sheet; my heels were digging into the mattress; my breath was held inside me; I could not breathe; I was frozen in illicit pleasure.
