It was six days since I had inadvertently observed my wife, Denise, totally sexually dominating my big sister, Kelly. I had stumbled upon something I couldn't fathom but my confusion was only increased by my own feelings at watching Kelly submit sexually to Denise, orally pleasure her and be fucked like a bitch by Denise's wicked looking strap on dildo. And then came the final revelation that what I had witnessed was to be repeated the next Wednesday and that my and Kelly's mother would be there! As sick as it seemed there was no way that I was going to miss out on what (and who!) went down in my very own bedroom.
So I knew that Kelly was due to come around again the next Wednesday and I spent right up to the weekend trying to think of the best way of viewing what happened. I assumed that the action would unfold in the bedroom as it had before and could not believe that I would be able to hide at the door and catch a stilted view of it through the crack at the hinges to the door and not be seen again, especially if there was another person this time. When Denise went out with friends (and by now I was really wondering about my wife, was it really her friends she was going out with?) that Friday night I went up to the loft and looked for any holes in the roof that I could enlarge to see down into the action, there weren't any, it was a modern house, and if I was to create one surely it would be obvious plus that idea had an obvious flaw in how did I intend to get up to the loft and close the ladder behind me – I ended up abandoning it after an hours thought. Under the bed was hopeless so I ended up concentrating on my wardrobe.
You see we had separate wardrobes for our stuff in the bedroom and mine was looking like my best bet for seeing what happened and remaining undiscovered. It was solid, high and, most importantly had a series of ornate grills carved into it that, cast in shadow, that would afford me an almost perfect panorama of our bedroom. I shoved some boxes at the bottom and stepped inside, pulling the door closed behind me. It was just as well I was not claustrophobic because it sure was cramped and dark in there but it was the prefect hide for me and I decided there and then it was to be my hiding place.
From there it was relatively easy, I took Wednesday as a day's holiday from my work, did not tell Denise, headed off for work as normal that morning, parked a couple of streets away then waited for her to head to the shops to buy her morning papers before nipping back into the house and concealing myself within the tight confines of the wardrobe with just a bottle of water to keep me hydrated. I was in position and all I had to do was wait and wonder. For the millionth time that week I tried to figure it all out, why had my wife treated Kelly like that and done all those things to her and what on earth were they going to do today. Was she going to fuck her again and would I be so aroused again, and where the hell did mum fit into things? At around ten thirty our front doorbell rang and I braced myself to find out.
I had been in there for the best part of an hour and although I had been tempted to venture out and have a stretch I hadn't, I had heard Denise downstairs moving about but I didn't want to risk being heard so I stayed there. I actually froze when I heard the bell, I stood there dumbly and tried to steady my breathing, I could hear the noises of people ascending the staircase and I stepped back slightly to allow me the best view through the slats in the door plus give me a degree of shadow in case anyone cared to look at the wardrobe closely. It was my wife that entered the room first and it was my first surprise of the day when I saw what she was wearing.
Not to put too fine a point on it my wife was dressed sluttier than I had ever seen her or ever imagined seeing her. She had long, knee high black boots on, with thin stiletto heels that boosted her short frame considerably. Above that she had on a pair of rubber black pants that were mostly hidden by the monster strap on dildo I had seen her use so effectively on Kelly last week, and covering her small tits was a lace together black Basque. Like I say, she sure looked like a slut but I got stiff just looking at her like that, what with her long blonde hair pulled tightly back in a ponytail. My sister, Kelly, followed her into the bedroom wearing a very dowdy jumper and trousers, her eyes were cast down and she didn't resemble the strong woman I had spent so many years with. Denise pointed to the far corner of the room and demanded.
"Get stripped off whore, all of it, and quickly you dumb fucking slut!"
I still could not get used to my normal sensible, prim, proper wife speaking like this and the tone of her voice was, if anything, even worse. And Kelly just stood there meekly nodded and started to strip off! It was all as mad as I had remembered it. In her though I was even closer and could examine my curvy sisters body all the better and let me tell you, close up she was fucking good looking!
I flinched a little as Denise threw a small object, I strained to see what it was but couldn't. Then Denise answered for me.
"Use it to write the word "WHORE" on your fat belly, just so you remember what you are. And remember to write it in nice thick letters."
From my hiding place I had a close up view as Kelly wrote the word large and dark with a marker on her creamy, smooth skin. Why did it make me so hard?
"Now that might be a permanent marker, I can't remember, still it'll do for now, eh whore?"
"Yes Denise."
Just then the door bell sounded and I expected Denise to answer it but I had a surprise coming.
"I can't be bothered answering that Whore, you get down there like that and answer it, if it's the milkman tell him I'm out!"
I was getting used to my sisters timid acceptance of whatever my wife said so, despite that comment and the inherent risk of answering the door like that, I was not surprised to see Kelly rise up and stalk from the room to descend the stairs. Denise gave her ass a swat as she passed and as she left the room I focused on my wife. She was like a different person, this harridan that stood impatiently at the far window was barely recognisable as the woman who I had married and spent the past three years with, it was quite disconcerting, maybe I should have done something then or over the last week but I am ashamed to admit I was so turned on and desperate to see what was going to happen it was an option I barely considered. God she looked hot though! I couldn't but help reach down and begin to slowly stroke my cock through my trousers. As I did so I tried to convince myself it was Denise alone that was arousing not anything to do with my sister.
Denise looked up sharply and for a brief moment I thought I had been discovered but her keen eyes sought elsewhere, concentrating on the open door and the two figures who came through it, Kelly came in slowly followed by my mother, Angela. I've always though my mum was a striking woman, very good looking for someone in her early fifties, her dark hair retaining its colour well and her figure more that of a thirty year old. She had never really got on with Denise, not quite the open hostility that was displayed previously between Kelly and Denise but a fairly apparent distrust and dislike that both obviously papered over to keep me happy. She never said so, but I'm sure mum thought I had married below myself and Denise wasn't really good enough for me. So relations had been stilted at best and although they were polite to each other I was never under any illusions they would become best pals. Once again I was stunned at the harshness of the tone Denise took to her mother-in-law.
"You're late you stupid cunt! I told you fucking half past, didn't I?"
