Malcolm Potter was feeling awful – there was a sinking feeling in his tummy. He just had no idea how the next ten minutes would play out. He just knew he had to speak to Jane and he was dreading it. It was all too complicated, but there was no way he could pretend everything was alright and that it would sort itself out. He got to the front door and hesitated. He would have liked to have turned round to walk away – but what if she had already seen him? What would she be thinking if he just wandered off? She might phone Sue. He rang the bell, hoping she was out, but knowing she wasn’t.

“Oh, hi Malc. Lovely to see you – come in. What brings you over this side of town? Fancy a coffee?” Jane was already filling the kettle as Malcolm just stood in the kitchen feeling helpless

“Errm – er Jane – I need to talk to you. I have to tell you something.”

The tone in his voice made the bright smile on Jane’s face begin to fade.

“What is it Malc? What’s happened? Here, come and sit down,” she said leading Malcolm by the elbow to a stool at the breakfast bar. Come on tell me – I’m not going to bite, what is it? Are you alright? Is Sue alright?”

“I’m sorry Jane, but Rob is having an affair with Sue. In fact they’re at our house at the moment.”

Jane went still and her mouth fell open.

“No!” she cried, “it can’t be – you must be mistaken Malc. I don’t believe it. My husband is having an affair with your wife – my own sister? How do you know?”

“I’m really sorry Jane. I found out a few weeks ago and I hid a web cam in the bedroom. I’ve got some of it here on a memory stick. If I had discovered her with another man we would have had a hell of a row and it would hopefully be over – but having sex with her brother in law, well it wasn’t as simple as that. I know that the two of you have always been so close to each other – I didn’t want to spoil that. But dammit it Jane, she’s my wife and I love her.”

“Oh God this is a mess. That stupid little cow what does she think she’s doing? I’m going to have Rob’s balls for this. Look show me what you’ve got on the stick will you?”

They plugged the stick into Jane’s laptop and the evidence was irrefutable. Malcolm felt a bit sick and he found sitting close to Jane as they watched their respective spouses going at it for all they were worth was a strange experience. Sue had her legs over Rob’s shoulders as he pounded away at her pussy. She was telling him to fuck her harder and Rob was promising to fill her cunt with his spunk – hardly an erudite conversation, or a gentle romantic one at that.

“Enough!” snapped Jane yanking the stick out of the machine. Her face was a mask of fury. “Right, we are going round there now Malcolm Potter and we’re going to catch them at it.”

Malcolm was not sure that this was going to be the best tactic – he cringed at embarrassing scenes, but Jane was not a woman to be gainsaid at that moment. She was literally dragging him to her car. On the drive over she seemed to calm and to be planning.

“When we get to your house Malcolm we are going to leave my car just round the corner. We will enter the house very quietly. If they are up in your bedroom we will simply sit in your lounge and wait for them to come downstairs. Then my dear, – you may leave the talking to me. Is that clear?”

“Yes,” squeaked a now terrified Malcolm.

They arrived and entered as planned. The noises coming from upstairs made two things very clear. The first that some very lively sex was, indeed, taking place. The second was that their walking on tip toe was not necessary. It was also clear that proceedings were nearing their climax.

“Yes, he’s shot his load,” whispered Jane, “I know those noises all too well – my stupid little sister now has her pussy full of his spunk.”

This was almost too much for Malcolm who moaned.

Jane immediately realised that her commentary was causing the poor man to suffer even more - it was after all his wife whose pussy was being filled, and she held him close to her.

“I’m sorry Malc, that was stupid of me. Look, don’t worry OK? I will sort it.” She pulled him in close and Malcolm found he enjoyed being comforted – he certainly enjoyed the brief soft kiss she bestowed on his surprised mouth.

The noises from upstairs were now those of a couple disengaging and getting dressed. When the bedroom door opened Jane stepped slightly in front of Malcolm as the erring couple descended the open plan stairs. Jane filled her lungs.

“Robert Bradley and Susan Potter – adulterers and fornicators,” cried Jane in a voice that declared dire doom to be upon them all. “Do not even think to deny what you have been doing upstairs. I know the sounds you make Robert Bradley when you shoot your load. Today you appear to have been firing at the wrong target. I will deal with you at home – my car is round the corner – move!”

At the first sound of the horn of judgment Robert cried several expletives. Susan shrieked and screamed before shrinking into a foetal position. Malcolm screamed as well but managed to stop himself from running to hide behind the settee; such was the avenging fury being vented by his sister-in-law.

“Susan Potter,” she went on quietly, “you and I will have words. I will be back here at 3.00pm precisely tomorrow. You seem to have difficulty remembering that we are no longer children and that we no longer share absolutely everything. Now! You have a poor beautiful husband here who has been wrecked. If you do indeed love him, get on and make him believe it.” With that Jane marched out of the door in pursuit of the hapless Robert.

The following day, at precisely 3.00pm, Jane Bradley marched in to Susan and Malcolm’s house once more. She did not ring or knock – she simply made her entrance and walked into the kitchen to confront her sister.

“Well?” she asked.

“Well?” responded Susan, with a gentle smirk on her face.

Jane’s face cracked into a beaming grin. “That will teach him to say ‘no’ when I need a new car. It worked beautifully. We went to Hobson’s this morning and it will be delivered on Friday. He even agreed to the Series 5 model and alloy wheels”.

“Yeeaaagh! High five girl!” yelled Susan, “don’t you love it when a plan comes together.”

“How is poor Malc dear? I was worried about him. Is he OK now? He was absolutely terrified of speaking when he came round to see me yesterday.”

“Yes, I screamed remorse and begged forgiveness. I outlined a plan by which he knows I love him and knows he’s special. Not a difficult thing, because I do love him and he is special. Anyway, he got to fuck my ass last night and I gave him a morning blowjob before he went to work. I also promised him a ‘special’ tonight.”

“Thanks Sue, I owe you. Oscar should be on its way. Let me know if there is anything I can do to pay you back.”

“Well! Come to think of it…”

“What? – name it, you’ve got it.”

“There’s this Caribbean Cruise I fancy but Malc won’t hear of it – says it’s ridiculously expensive.”

“Okay,” said Jane, “how about I cry ‘woe and thrice woe’ that Rob had sex with you and weep all over him. Then I suggest that I could only feel right about it if he had some recompense upon Rob’s wife? Then after he has had his wicked way – rely on me here girl, it will happen; he will be overwhelmed with a sense of guilt. I tip you the word and you raise the subject again.”

They grinned and hugged and broke into their song.

“Sisters, were there ever such devoted sisters?”
