At the start of lockdown my youngest son and his partner asked me to live with them for what we assumed would be a month or so. I am in my seventies and live alone and they were concerned about me. I was a little worried by the rising cases and agreed. They are in their thirties, both work in high pressure jobs but would be working from home for some of the time. They have a large 4-bedroom house and I had a bedroom and exclusive use of the family bathroom. They have an en-suite shower room within their bedroom at the other end of the house. They have no children but after a couple of days even at some distance from their room it was clear that they were putting in plenty of practice. They were very loud in their love making and lots of giggling and shushing, probably when they remembered I was living just down the hall. Karen, Gary's partner was a tall, nicely built girl, slim hips and not massively endowed in the breast department but very attractive. I had, a number of wonderful wanks thinking about them shagging away some 20-30 feet away. As April passed, I pottered in the garden, trimming shrubs and generally tidying while they worked on their laptops indoors. Gary had a study just inside the front door and Karen had a work room in one of the smaller bedrooms. I saw little of them during the day but did make tea and coffee for them a couple of times throughout the day. As April disappeared and we moved into May with no sign of an improvement in the pandemic's course we just carried on with the arrangement. I sited a garden lounger in a slightly shaded part of the garden and spent hours reading and I often dozed in the warm sun. As it got warmer Karen started wearing very light clothing, especially shorts and they were very short leaving little to the imagination and strappy tops with no bra. It was wonderful to look at and on a couple of occasions she brought me a drink as I dozed on the garden furniture and as I opened my eyes her crutch in those skimpy shorts was just at my eye line and less than a foot way. She put down the glass and squatted down next to me to ask if I was okay, so then her tits were in my eye line. What a life, the old togger started to stir in my pants, it was a lovely feeling watching her as she walked back across the lawn and through the French windows. In the split seconds from opening my eyes I had taken in the view of her mound in the shorts, which I think had a thin liner so she was not wearing panties and then the hint of her nipples pushing against the fabric of her top. Lovely times and great memories for wanking, later. One afternoon, having got too warm and went into the house and as I climbed the stairs, I could hear obvious sounds of love making. I hesitated outside their bedroom door and heard them going at it. I noticed for the next few days especially when I was in the garden that they worked mornings, shagged for a while after lunch but then often worked again during the early evening, leaving me to watch their 55 inch television, by myself in the lounge. One evening bored with what was on TV, I headed up to my room assuming they were working away in their separate rooms. As I reached my room door, I decided I needed a pee so opened the bathroom door whilst also opening my flies and pulling out my dick. I am at an age that when you need to pee, you have to pee, straightaway, so often get it out ready as I approach the toilet pan. To my shock Karen was laying in the bath. Me with dick in hand and completely flustered. ‘Oh’ she exclaimed something like ‘I hope you don’t mind I fancied a soak in the bath’. ‘No problem’ I managed to say, ‘do you mind if I pee’ or something like that, we were both flustered. Without waiting for an answer, I shot a stream into the toilet pan, I was trembling with excitement and trying not to spray all over the place. As the flow ended, I shook it and started to put back into my underpants. Karen suddenly asked me not to put it away and let her have a closer look. I obediently turned to face her, she had risen from the water and was laid with he left arm on the side of the bath. Her breasts had broken the surface and were glorious to behold, just perfect in size and shape with a hint of soap suds on the nipples. I remember her words, ‘Now I see where Gary got his nice big prick from’ she said and reached out, I started to back away, but she said wanted to touch it, hold it for a moment. I moved forward and she took a gentle hold on my rising manhood, she expertly wanked it up and down. My knees felt weak and I thought I would collapse. She sensed this and knelt up in the bath and I half-turned and sat on the edge of the bath, she was now partly behind me and tossing me off, with her left hand. I was the hardest I could remember being for many a year. I looked to my left and could see her whole body knelt in the bath it was as beautiful as I had imagined. She smiled and whispered that she loved the way I looked at her whenever we were close together in the house or the garden. She could not resist finding ways to tease me more and more. She asked me to cum for her, it was my reward for making her feel desirable. She stepped up the speed and I came in huge spurts onto the bathroom floor. It was a fantastic relief and I felt weak and shuddered. She wrapped her wet arms around me and hugged me for some time. After a short while she laid back in the bath and gave me a great big smile. Not knowing what to do I rushed out to my bedroom, shaking and very uncertain what or why that had happened. I undressed and got into bed, gently wanking a surprisingly stiff penis, until I guess I fell asleep.
