My mother was just forty five and had a form of dementia brought on from an accident with a car.  She could remember everything perfectly from before her accident but anything that happened yesterday would be erased overnight and everyday was a complete new day with no memories of the previous days back to the accident.  She carried a book with her everywhere and wrote down everything she thought she needed to remember.  My father the bastard walked out on her  leaving just the two of us.  My mother had great support from her best friend Tricia.  Tricia lived two houses away  and often said that she wished it had been her husband that had walked away. 

Tricia was two years younger than my mother and they had been friend from their school days.  I grew up calling her auntie Tricia.  At about eleven or twelve when I first started noticing girls and women Tricia would tease me about girlfriends.  At that time I didn't have one and developed a crush on Tricia.  Years later Tricia was now forty three and I was twenty one.  She would still tease me about girlfriends only the teasing was more sexually focused with lots of double meanings.  The years had been kind to Tricia and not having had any children she had maintained a terrific figure.

My mother had got some brochures for foreign holidays.  She had been away before abroad, before her accident, and wanted to go again.  I was there when she asked Tricia to go with her.  Tricia had never been abroad and while she liked the idea was concerned that two women abroad alone would be vulnerable especially as one of them wouldn't even remember what happened the previous day.  I butted in and said that I would go with them.  My mother wanted to go to Egypt to see the pyramids.  So the destination was fixed and I left it up to Tricia to sort everything out with my mother and book it, telling them I would pay for the trip. 

It seemed no time at all that we were on the plane to an all inclusive hotel.  On arrival we were all tired and very hot.  Tricia had booked a single room for me and a twin room for herself and my mother.   On arrival the single room was ok, but the hotel had seen that my mother and I had the same surname and thought we were a married couple and given us a double bed room.  We tried to get the room changed but was told that the hotel was in fact over booked and they were shipping people out to other hotels.  They offered as their only solution was for me to move to the other hotel.  Neither Tricia or my mum wanted that and Tricia said we would make it work.

I had expected my mother and Tricia to take the double bed, but to my surprise said that she would share it with me.  We got my mother settled and as it was late Tricia saw her into bed and came to the double bed where I had already got in bed in just my pants as I don't normally wear pajamas and besides it was very hot.  I had expected Tricia to go into the bathroom and come out in a nighty or something.  Imagine my surprise when she just stripped right off in front of me.  I was now laid in bed with a good hard erection and had to roll onto my side to hide it.  As soon as Tricia slipped into bed I could feel her warmth and that only served to make matters worse.   Although I was very tired it took me hours to get over the erection and get to sleep.

The next day I was up and dressed before Tricia woke.  When she woke she sat up and with the thin covers falling away from her and  I had a clear view of her plump titties.  I quickly told Tricia I was going to check on my mother as she might be confused at waking in a strange place and strange bed.  Really I needed to get out of the room to hide my growing erection.  My mother was OK and had written to herself to tell her where she was and why. 

We had opted for some trips and we were soon back on a coach for our first day out.  It was a very hot day and we had a hot but enjoyable day.  That evening after our meal we retired to the bar and both my mother and Tricia were soon enjoying cocktails while I had a few beers.  My mother was scribbling lots of notes to herself about the day so tomorrow she could read what she had done and seen.  By the time we headed off to bed both My mother and Tricia were a little tipsy.  Tricia again made sure my mother was in bed ok, and wrote in mothers book the phone number of our room.

Again I was already in bed by the time Tricia returned to our room.  Like the previous night she just stripped and my erection returned as I watched her strip.  I had forgotten to roll onto my side and Tricia quickly spotted my erection straining against against the thin bedding and my pants.  In her teasing normal way, she teased was I packing a gun or just pleased to see her as she got into bed.  I'm not sure if her inhibitions were lowered by the drinks or if it would have happened anyway, but as she got settled her hand came across the bed and landed firmly on my erection.   Now she teased that I was clearly pleased to see her as she started to rub my cock through my pants.

I think it was the comment that I was bigger down there than her husband and that she was looking forward to feeling in in her pussy that had me exploring her plump titties and kissing her.  At twenty one I was far from being a virgin but I was definitely new to making out with a woman old enough to be my mother.  Then Tricia asked me to lick her fanny and not wishing to disappoint I was muff diving in seconds.  I had been at it for some while when Tricia gasped at me to fuck her .

I soon had her legs over my shoulders as I slammed in and out her pussy and it wasn't that long before she was telling me to come in her.  Come I did as she groaned through her own pleasure and I pumped my cum into her pussy.  Afterwards I cuddled up to her as we fell asleep.  Next morning I woke to find Tricia sucking my cock that was already stiff and ready for action.  Tricia mentioned that it was quite some time since she had last seen a good morning woody and she sucked me for just a short while longer before telling me to fuck her doggy style.  It was a great fuck and I enjoyed reaching round her for her plump titties.  Afterwards I showered quickly before going to check on my mother.  She was happy and sat in a chair reading what we had done the day before. 

There were no trips today and both mum and Tricia decided that a nice relaxing day beside the pools would be good.  It wasn't long before two men came and sat near the three of us.  Already I was finding it a bit too hot and went for a dip.  On my return two the men had moved in on mum and Tricia and was clearly chatting them up.  After my night with Tricia I felt jealous seeing another man chatting her up.  Although it felt strange seeing my mother getting chatted up, somehow that seemed ok.  After lunch the two men were back chatting to them again.  The one that was clearly taken with Tricia suggested that they had dinner with them.  I don't think he was expecting me to tag along with them.

Later in the bar I explained to the one chatting my mother up about her memory problems and he joke saying that she would definitely remember when he had fucked her.  I found him a little rough to say the least.  He thought that Tricia was my mother and was apologetic when I told him it was my mother he was talking about.  Eventually the one chatting Tricia up wandered off as his advances while not being strongly rebuffed weren't being reciprocated.  His mate soon followed him.

Mother firmly tucked up in bed I was soon back between Tricia's legs sucking and licking her pussy before another great fuck.  The next morning we were booked in for a trip to the pyramids and we soon learnt that the same two men were also on the trip.  Today the two men rotated and the one man sat with my mother and his mate with Tricia.  It was like I was a spare wheel tagging along behind them.  The guy with my mother was surprised she couldn't remember her from the previous day and I had to tell him about her problem. 

Unlike his mate he seemed more refined and was gentle with her and enjoying her company.  After all she did have just over forty years of memories and knowledge.    It was a good and hot day, even if I was a spare wheel.  That night after dinner they again both sat with us and the man with Tricia kept the cocktails coming clearly wanting to get into Tricia's knickers.  I was left out of the rounds of drinks and had to get my own.  They both looked disappointed when Tricia told them she was putting my mother to bed and also going to bed.  The man with her snatched a quick kiss and asked for her room number.  Tricia told him no, besides three in a bed would have been cramped, although she didn't tell him that..

We didn't see them again for a few days and we spent one by the pools and another in a bazaar browsing and shopping between being harassed by the stall holders and the kids begging for small change. Each evening and morning I spent making love to Tricia who teased me about being jealous that she was getting chatted up.  Then the men were back and the nicer man was again chatting with my mother.  That night after lots of drinks Tricia again blew her pursuer off with just a peck on the cheek, and after she had seen my mother to bed we were again making passionate love.  Next morning after another steamy session I went to check on my mother.

Imagine my shock not to mention hers when I found her in bed with the nicer one of the two men.  The room wreaked of sex.  I left to give them time to dress after finishing screwing.  When I told Tricia she thought it was funny that I had caught my mother with a lover.  After calming down I agreed that it was ok for her to have some pleasure.  His mate had decided that he was wasting his time with Tricia and just the four of us spent the day at a beach and a little shopping center.  I was getting to quite like the chap.  The rest of the holiday he remained being with my mother and sleeping with her as I did with Tricia.

The last night his mate had returned and again tried his luck with Tricia and again she let him down gently.  There was entertainment and a dance at the hotel.  We hadn't bothered before, but we decided to take a look at the entertainment and we went to the dance.  My mother had always been a good dancer and her chap was also pretty good.  Tricia now had another suitor, a guy of about thirty years old and as I don't like dancing, she spent a fair bit of time with him on the dance floor.  I got chatting to two nineteen year old girls.  The one made it clear that she was happy to sleep with me.  Tricia seeing what was happening suggested that I take her back to our room and have some fun as it was our last night.  She said she would give us plenty of time before coming up to bed.  Pauline was surprised that I had a double bed.

I was soon fucking Pauline for all I was worth in mine and Tricia's bed.  She had a nice curvy arse, but lacked the tits that Tricia has, but none the less was still a good fuck.  In fact two fucks, as I did her in missionary and then doggy style.  Afterwards we returned to the dance and my mother and her chap had gone off to bed.  Pauline said she was shattered from our fucking and also left for her bed.  I looked for Tricia and she was nowhere to be seen, but Pauline's mate Roz was still there and we wandered out of the hotel and ended up making love beside the pools.  Afterwards I walked her back to her and Pauline's room before heading back to mine and Tricia's room.  Still no Tricia though.

I had just dozed off when Tricia returned looking really disheveled.  I was as jealous as hell knowing she had been shagged rotten by someone else.  It was stupid being jealous as tomorrow night Trisha would be back in her own bed at home with her useless husband probably shagging her making up for missed time.  Besides I had shagged two girls earlier in the evening.  Tricia cuddled up to my back as we both tried to get some sleep.  Neither of us was able to sleep and ended up talking.  She told me that her thirty year old dance partner had done another type of dace with her in his room.  She said she had enjoyed it but added that I was a more considerate partner.  The chap she had been with, barely knew what foreplay was, let along oral sex.  I told her of my evening with Pauline and Roz.  Tricia seemed genuinely happy that I had shagged two girls my own age.

We eventually went to sleep with Tricia holding my limp cock.  Next morning I gave her what I thought would be my final fuck with her.  Then I went to make sure mum was getting packed for the journey home.  Imagine my shock to again find her in bed with a man.  In fact two men.  Her nice man was joined by his cruder mate and while she sucked the nice man's cock, his mate was fucking my mother from behind giving her a spit roasting.  They both stopped as I reminded her that she needed to be packing ready for the coach back to the airport.  As I left the room I heard them return to fucking my mother.

I told Tricia what I had just witnessed.  Unlike me she found it funny.  We finished our packing, and collected my mother who was now doing her packing, to take her for breakfast.  Then we were back on the coach and the plane for home.  My mother was quickly asleep and Tricia was dozing.  My mother's book was in her lap and I knew I shouldn't but I took a look in it.  She had written a lot about Brian the nice man and that he made nice love to her most nights.  She wrote that he was very tender and gentle with her and she liked him.  Last nights and this mornings entries wrote that the two men had taken turns with her several times and she had thoroughly enjoyed it.  In fact she hadn't been asleep at any point in the night as between the two men they fucked her silly keeping her awake.  How three people managed in a generous single bed I will never know, but they had.

Then I looked back at several days entries.  Brian had favorable comments about him on each page.  Three nights back, both men had taken my mother from her room to their room and each fucked her several times before returning her to her room.  My mother had written while she had enjoyed the sex immensely she didn't like Gordon the cruder one anywhere near as much as Brian.  I was shocked and stunned at her frankness and she had put a comment that it was a bit like an evening with BG and RH shortly after finishing college.  Some while later talking with Tricia she knew who the two men referenced by their initials were and joked that my mother was a dirty mare having had a threesome with RH who had been one of her boyfriends.

Back home to my utter amazement Brian turned up and took my mother out for an evening.  He was working in the area and ended up staying for a few nights sleeping with my mother.  Then after a brief spell back home he returned and moved in permanently, and a year or so later my mother married Brian.   It was funny to watch my mother some mornings asking Brian who he was and why was he in her house.  He had been very good to her and looks after her well. 

For me I move out of my mothers house, just two door away when Tricia finally kicked her husband out for cheating on her.  If only he knew that I had fucked her all those times on holiday as well as her last night fling with her thirties man, plus we fucked each and every opportunity we could since we returned home.

Tricia is now in her seventies and is still sexually active although nowhere near as frequently and not the long nights of lustful sex we used to have.  I love Tricia dearly and since the last night of that holiday, I have never slept with another woman.  At first when we were together people assumed Tricia was my mother when we were out.  Now in my fifties and having gone quite grey haired people accept that we are together as a couple, although we never married.

I am so grateful to the Egyptian hotel that mucked up our sleeping arrangements and brought us together.
