She came to my bed that night and we again used hands and mouth to pleasure each other before she returned to the marital bed. I slept happily and deliberately on the damp patch created by her pleasure. In the morning she brought in two mugs of tea which duly got cold and we started the day proper in time for lunch again. At four I said 'Hi' to Bill then left them to it while I cut the back lawn. That night she again joined me in bed before going to her marital bed to sleep.
In the morning, in accordance with my suggestion, she came into my room without any tea and just slipped into bed beside me. Using her head she worked the covers down until she had exposed my cock. I was told to wriggle down and did so. She straddled my head, lowering her wet cunt onto my face as she lowered her mouth onto my cock. A position that the previous night had taken ten minutes to reach and a full fifteen the previous morning. Despite my advancing years my cock was very soon at the point of no return.
"Fuck me!" she demanded.
I suspect that we had both been a bit delusional. We had spent time in bed together. Pre WW2 that in itself was grounds for divorce but this was the twenty first century. We had been naked together. We had enjoyed mutual masturbation and shared the joys of oral sex together but she was Bill's wife and we hadn't actually fucked, so that was alright then. Wasn't it?
She rolled off and repositioned herself straddling my hips. The soft, slow sigh of sublime satisfaction that escaped from her lips as she lowered herself onto my unresisting cock made it perfectly clear that 'are you sure about this?' was utterly unnecessary. We fucked and rested and fucked again. Lunch was a couple of rounds of sandwiches and a piece of fruit and I warned her to wipe the smile off her face before we spoke to Bill.
I told Bill 'Hi' and went off to cut the front lawn. Sue found me asleep in the conservatory an hour later.
As I have suggested, I'm no spring chicken and Sue, bless her, never once made complaint about the effort she need to make to make my cock fit to fuck once we had started to fuck on a very regular twice a day basis. Nor did she complain that once I had filled her greedy pussy with my spunk that I couldn't do it again. I like to think that where my cock failed my fingers and my mouth ably compensated. I did have the solution but it was at home and I kicked myself for not even considering that it might be useful. I told Sue that I needed to pop home for a few days. She told Bill and he asked if I would mind taking her with me. I didn't mind at all.
The first night I took a small piece of pill and we fucked until she begged for mercy and finally wanked me off into her mouth by way of compensation. That night she didn't sleep in the bed that she and Bill usually slept in when the visited me. She shared my marital bed. In the morning we were both ready for more and missed lunch as well. The 4pm chat with Bill was taken in the dining room with the iPad on the table, Sue sitting on a dining chair and naked from the waist down. After five minutes telling him about the journey home I left them to it and went to prepare a very late snack for two. Sue didn't dress completely that day nor the following and for the whole two days she was intent on finding out how long the effect of the pieces of blue I was taking lasted. She got no complaints from me. We went to bed early and got up late but always in time for Bill.
We stayed at mine for a week, returning to Sue's five days before Bill was due home. For the first three days we fingered, licked, sucked and fucked like rabbits with Sue returning to the marital bed to sleep each night. For the last two days we stopped almost completely restricting ourselves to a little light mutual masturbation. The night before Bill's return we went to our own beds alone and in the morning of his return we were up bright and early. I drove us to the airport to meet him and dropped them back at home. Leaving them to catch up with some serious quality time I headed back to my own home.
That was all eighteen months ago. Now, while Bill's away, Sue comes to mine or I go to hers. She is made welcome by my neighbours and I by hers. What could possible be wrong with that? After all she is my daughter-in-law.
