"Tell me, Matthew, do you like my bottom?" sixty-three-year-old Elizabeth St. John asked the younger man standing before her.
"Not so loud Elizabeth, someone will hear you," replied thirty-eight-year-old Matthew Sinclair, fearing that someone amongst the eighty or so people at the party would hear his rather loud-voiced mother-in-law.
"Oh, don't be such a prude and answer the question," said the rather tipsy mature woman.
"You have been drinking, Elizabeth," was Matthew's next gambit in trying to change the subject.
"Of course I have been drinking, it is a party, now tell me if you like my bottom," insisted Elizabeth.
"Yes, I like your bottom, but I am having no more of this conversation," said Matthew before walking away because although he was not sober he was sensible enough to know not to be having this conversation at this time.
Actually, Matthew really did like Elizabeth's backside and he had liked it for all of the seventeen years that he had been married to her daughter Kate and for the two or three years before that that he had known her. Elizabeth's bottom was much more substantial than her daughters and with Matthew being a bit of a 'bum man', he sometimes wondered what had attracted him to Kate because it was certainly not her backside.
The party continued and there were no more such questions from Elizabeth although Matthew did once get in a position so that he could study his mother-in-law's behind which was currently in a rather tight-fitting and expensive dress.
A little later, Elizabeth was in deep conversation with her other son-in-law, Charles, and Matthew wondered if she was asking him the same question.
That night at home in bed, Matthew could not settle and his thoughts were mostly on Elizabeth and more particularly, Elizabeth's arse, and Matthew found that his cock was stiff. Kate was fast asleep, not that Matthew was interested in her at the moment and if truth be told, not too interested in her anyway, so Matthew got out of bed and went to the bathroom and wanked into the toilet thinking of Elizabeth's St John's buttocks.
In the morning he thought that Elizabeth had been so drunk that she would not remember their brief conversation, but even if she did, she would be embarrassed by her alcohol-fueled question.
Actually, Elizabeth did remember the conversation and she was not particularly embarrassed by the question although she did think that she probably should not have asked it. Elizabeth had been thinking a lot about her bottom recently, and sexual things in general, because although her husband Stanley had not been interested in her sexually for years, she had spent a lot of time on her laptop looking at sex videos and sex sites and all sorts of things had been coming into her head.
It was mid-morning when Matthew's mobile rang and he was surprised to see it was Elizabeth calling because she very rarely rang him directly.
"Hello Elizabeth, how are you?" asked Matthew, who had always called her by her first name rather than 'mum' or such like because that was what she had wanted.
"I am alright, thank you but about our little chat last night," she started.
Thinking that she was phoning to apologise or whatever Matthew said, "Oh don't worry Elizabeth, forget it."
"Are you saying that you do not like my bottom?" she asked slightly indignantly.
"No I am not saying that, but we had both been drinking," replied Matthew.
"Matthew, I have been looking at things on the internet and I have discovered this thing, they call it ass worship or something I think," said Elizabeth sounding slightly excited.
Matthew was more stunned by this than he had been by the question the night before and he did not respond, "Matthew, are you there?" asked Elizabeth.
"Yes I am here, but I do not understand why you are telling me this Elizabeth," said Matthew, although visions of having his face in Elizabeth's buttocks came into his mind and transmitted to his stiffening penis.
"Have you heard of this ass worship thing Matthew?" was Elizabeth's next question.
"Yes I have heard of it, but I still do not know where you are going with this," said Matthew who was now close to full erection in his trousers.
"I want someone to worship my arse and I want you to do it, Matthew, don't you see?" said Elizabeth pleadingly.
"Elizabeth, I am married to your daughter, we can't," said Matthew, although he was wishing that they could.
"Do you worship Kate's arse?" asked the older woman.
"No, she does not like having her bottom touched, and anyway she has not got an arse like yours," blurted Matthew who then knew that probably he should not have said the last bit.
"So you would like to worship my arse?" said Elizabeth gleefully.
"Fuck yes, but we can't, can we?" said Matthew honestly and also giving Elizabeth the chance to possibly have the final say on the proposal.
"Well, if you want to and I want you to, then why can't we?" asked Elizabeth.
"Because of Kate and your husband of course," said Matthew, although he sort of hoped that Elizabeth overrode that statement.
"Well, Stanley would probably not care less and neither you nor I would be telling Kate would we?" she said logically.
Matthew was still unsure, not about doing it but about Elizabeth's motives, "Are you really serious? You are not doing this to get me into trouble with Kate are you?" he asked.
"Yes I am serious and the last thing I want is for Kate to know about this conversation or anything that we might do in the future, I want you to sexually excite me by playing with my bottom," said Elizabeth thinking that she could not make it any clearer.
Matthew's erection was telling him that this was an opportunity too good to turn down, "Elizabeth I would love to," he said.
Delighted that there was no 'but' Elizabeth said, "I will phone Kate and ask if she could ask you to call around here tomorrow because there is something that I need some help with," announced Elizabeth because phoning Kate would be her normal way of asking if Matthew could visit her.
Elizabeth phoned her daughter that evening and, after the call, Kate said to Matthew, "Mother wants you to call around and see her tomorrow, I said that you would."
Pretending to be disinterested and also a bit annoyed, Matthew replied, "Well, thanks, I wonder what she wants," and hoped that his wife did not notice the bulge that was starting to form in his trousers.
Matthew's normal relationship with Elizabeth was usually quite good without them ever really being close but what Elizabeth had suggested was about to make them a hell of a lot closer.
Matthew arrived at the very large house that Elizabeth shared with her husband with shared being the right word because they spent a lot of time apart in the vast building. Stanley was out at the local golf club and with the small number of staff that did various jobs on the estate elsewhere at the moment, Elizabeth had the house to herself.
She came out to welcome Matthew and she looked stunning in her white blouse and cream jodhpurs, she did not ride too much nowadays, but she still retained the equipment and clothing. Matthew's prick hardened as he got out of his car because the jodhpurs looked tight from the front and he just knew how her arse would look in them.
