Mature married couple Henry and Judith Golding, both aged fifty-nine, were going through a spell where they seemed to be constantly arguing or at least disagreeing about most things. Judith was finding Henry to be uncooperative in many ways and had just, for the second time recently, ruined their evening meal by not telling her that he would not be home from work on time.

"What is it with you at the moment?" asked Judith. "I should have a word with Helen."

Helen Watts was Judith's sixty-four-year-old sister and it was well known by family and beyond that she kept her husband Cyril under her control by applying frequent spankings to his backside.

"There is nothing wrong with me and what do you think your sister is going to have to say?" responded Henry.

Henry actually fancied Helen but had not told anyone that, least of all Helen. He also, although he would not admit it even to himself, rather liked the idea of going over a woman's knee for a good hiding.
 

"Well she does not seem to have any trouble with Cyril and we both know why that is," replied Judith.

"You are not thinking of spanking me are you?" asked Henry incredulously.

"No, but I am thinking of asking Helen to do it," replied Judith, surprising and exciting Henry at the same time.

"Don't be ridiculous," he replied whilst thinking to himself 'if only.'

"Take this as your last warning because if you pull any more stunts like tonight then I will ask her to deal with you."

Those words 'deal with you' caused Henry's already semi erect cock to stiffen even more.

The next day Judith had one of her frequent chats with her sister and decided to ask if Helen would give Henry a good spanking if it was deemed necessary.

"I think he is long overdue a good hiding and yes I would do it for you if you can't do it yourself," replied Helen to the question.

Helen actually found Henry rather attractive, as he did her, but was not telling her sister that.

That evening Judith said to her husband, "I have spoken to Helen and she says that she will spank you if necessary, in fact, she says that you should have been spanked long ago, so next time you give me cause I will be on the phone to her."

Henry hoped that his wife did not notice the movement in the front of his trousers as he replied, "You are not serious are you?"

"Yes, we are both serious so you had better behave," answered Judith.

Henry did not speak but he had no intention of behaving although he would have to try to make sure that his keenness for a spanking was not obvious.

After two days of longing to go over Helen's knee, Henry decided that he had to do something to make it happen.

Judith had asked him to get something specific from the shop so he decided that not getting it should prompt a call to Helen and a spanking.

On returning home and being asked for the item he replied, "Oh yeah, I forgot."

That prompted the response from his wife that he hoped for. "Right you were warned, I am phoning Helen."

He had to make some pretence at objecting so he said, "Oh come on, it is not that serious."

But to Henrys (hidden) delight Judith was already phoning her sister.

"She is coming straight round, you are going to get a good hiding," announced his wife.

Henry's cock jumped to attention in his trousers as he mumbled pleas for his wife to reconsider.

Minutes later Helen had arrived and was briefed by her sister on Henry's latest misdemeanour.

"Right I will tan his arse and if that does no good I will be back to give him more," announced Helen without specifically addressing either Judith or Henry.

Turning to her sister as she took a hairbrush from her handbag Helen asked, "Do you want to watch?"

"No, no take him upstairs and do what you have to do," replied Judith with an apprehensive and aroused Henry looking on.

Judith's answer pleased both Helen and Henry because, although neither knew it, they each wanted to be alone with the other.

"Right you, up the stairs," Helen ordered her brother-in-law.

The situation was surreal but Henry accepted the instruction without protest and lead the way up the stairs with Helen following, hairbrush in hand.

At the top of the stairs, she more or less pushed Henry into the master bedroom and part closed the door but did not close it completely.
 

Henry looked at the woman that he found very attractive who happened to also be the woman that was going to give him the spanking that he desired.

As Helen moved a chair into the centre of the room she said, "Drop your trousers and pants."

Henry was slightly aghast at this because, although he suspected the spanking would be bare arsed, he was close to fully erect.

He did not move straight away but a glare from Helen had him lowering both and exposing his reasonable sized penis which was standing quite proud.

Although Helen saw the almost rigid cock she did not comment but mentally sort of licked her lips as she hitched her skirt up to her waist and sat on the chair. She pointed at her lap and Henry put himself across it causing his penis to brush against Helen's quite thick thighs.

"You are now going to get the hiding you should have had years ago," said Helen as, without further warning, she started to bring the hairbrush down hard from cheek to cheek.

With the bedroom door partly open Judith could hear the CRACK! CRACK! CRACk! as the hairbrush crashed against her husband's buttocks.

On and on the beating went and Henry's arse cheeks became pink and then red and he yelped and squirmed as his sister-in-law landed whack after whack on them.

Although it was hurting him Henry was hugely turned on, as was Helen, as still the punishment continued.

Almost without warning, Henry felt his spunk rise and he started spurting against Helen's bare leg.

"You filthy animal," she hissed and CRACK! CRACK! CRACK! CRACk! she delivered full-powered whack after whack to the man's buttocks and he was now sniffling and crying.

The post ejaculation spanking must have got close to twenty whacks before she stopped and pushed him to the floor.

They were both breathless and red-faced and Henry was in tears as he scrambled to his feet and clutched his buttocks.

With her eyes fixed on him, Helen scooped the semen off her thighs with her fingers and put her fingers to her mouth.

As she licked her lips she said, "Next time I spank you you cum in my cunt, understand?"

A startled and very sore arsed Henry dumbly nodded his agreement.

"Get your trousers pulled up, you are going to apologise to Judith," said the wet knickered, although Henry did not know it, Helen.

Back downstairs the tearful Henry said sorry to his wife before Helen told her sister to call her when she next needs her, "He will get it harder next time," she added.

For the next few days, Henry was very subdued but thoughts of a further spanking plus the chance to fuck his sister-in-law kept coming into his head. Helen meanwhile looked forward to what she thought would be an inevitable call from her sister requesting that she returns with her hairbrush.

Sure enough, a few days further on, the call came and Helen was again at her sister's house with the intention of spanking (and fucking) her brother-in-law.

The offence that had brought this visit about was quite minor but Helen had warned that he would get it harder next time.

She had planned ahead how she hoped to accomplish getting Henry's cock between her legs without her sister being aware.

"This time I am going to spank him, then have a little break, then spank him some more," announced Helen before telling Henry, "You get upstairs and get your trousers and pants off."

Judith, apparently, saw nothing wrong with her husband being in a bedroom naked from the waist down with her sister so she sat down in the living room anticipating the sounds of Henry getting another hiding.

Once Helen, hairbrush in hand, was in the bedroom her eyes fell on Henry's erect cock as she removed her skirt and knickers.

Henry marvelled at her cunt and bush and then her arse as she fetched the chair.

"I am going to tan your arse and then we fuck and then I tan you some more, don't you dare cum on my thighs," said Helen as she put her big arse on the chair.

The bedroom door was as before so whilst Judith would be able to hear the beatings Helen hoped that she would not be able to hear any sounds from what happens in between.

Helen started to apply the hairbrush to Henry's buttocks but, at this stage, not quite as hard as before because she did not want him spurting. She had his arse glowing and she was loving feeling his erection brushing her thigs as he squirmed.

She stopped the beating and almost whispered, "Now fuck me," as she helped Henry off her lap and she lay on the bed legs wide apart.

Judith had been told that the spanking would be in two parts so she was not surprised that it had not yet gone on as long as the previous one did.

Meanwhile, Helen was guiding Henry's throbbing prick into her wet cunt and she had to prevent herself from crying out as he started to thrust because he was considerably bigger than her husband.
 

"Don't cum until I do, I am almost there," she breathed as Henry battled to stop his cock ejaculating.

Thankfully for both of them, Helen started to cum and she bit on her discarded knickers to stop herself crying out. This gave Henry permission to cum,  which he promptly did.

After they had both finished cumming she said, "That was lovely, I have wanted you to do that for years," as she kissed him.

"Oh Helen, I have always wanted you," replied Henry.

They both realised that Judith would soon be expecting to hear an arse getting spanked so, after Helen had put her knickers on to stop leaking their mutual cum everywhere, Henry was back over her knee.

Helen, rather cruelly, made this second phase rather savage having gone lightly on him the first time.

CRACK! CRACK! CRACK! CRACK! CRACK! resounded from the bedroom time and time again as Judith heard her husband's cries of anguish.

At last, Helen stopped and after putting her skirt back on and having the red arsed and red-faced Henry put on his lower clothing they were back downstairs with Helen telling her sister, "That should teach him a lesson but you know where I am if he needs another dose."

Helen and Henry looked at each other in a way that indicated that whilst another spanking might not be on the immediate horizon the prospect of another, more prolonged, fucking certainly was.

So Henry and Helen now both knew that the other found them attractive so there was every chance that they might prove it again and again and again.

There was also the added bonus that at any time Judith might contact her sister asking her to give her husband another good hiding.
