When I married Kate the last thing I had in mind was having an affair with my sister-in-law; but she intended to start one with me from almost the first time we met. That was at Kate's and my wedding, because we'd met and lived together in a different part of the country. Even at the wedding reception Diane was throwing herself at me, flirting with me at every opportunity, telling me in a suggestive manner that her husband was away on business a lot, grinding her groin against mine and groping my bum right throughout the one dance we had. Later that night, when Kate and I had our first screw as man and wife, I was shocked to realise that, as I came, it was Diane's face, and her plumped-up cleavage, that flashed across my mind, not that of the woman I had just married and was fucking at that moment. I told myself they were similar looking, and it was just a genuine mistake. It was one I repeated for the next two nights though.
I managed to hold out for six months; but when a younger, sexier version of your wife is putting herself on a plate for you the way Diane was with me, well, I would have had to be super-human to resist. It finally happened when her washing machine flooded her kitchen and I went round to fix it. I was squatting in front of the machine checking it, turned around to say something to Diane, and she literally thrust her naked blonde snatch into my face! Not surprisingly, within five minutes we were shagging over the kitchen table, and we haven't stopped in the nine months since.
It's not that I don't love Kate -- I do, very much. Superficially they do look quite similar -- barely over five feet tall, with wavy blonde shoulder-length hair and pretty faces with strawberries-and-cream complexions. But Kate's slim, quite an earnest person, and fairly reserved, sexually. Diane, on the other hand, is curvy with better nourished tits, she's funny, and she has absolutely no sexual hang-ups in bed, or anywhere else for that matter. I've done some really filthy stuff with her that Kate would probably lock me out of the bedroom for even suggesting. Diane's old man's a long-distance truck driver, and he's always struck me as a bit of a thug. They were married at 18 -- Diane's only 23 now, two years younger than Kate -- and she says he's about as subtle in bed as a steamroller, and doesn't give a shit about her needs or wants. By comparison, if she's to be believed, I'm the most sensitive, caring lover on earth. Of course, I take that with a pinch of salt, but what red-blooded bloke wouldn't take a bit of nookie on the side if it was that easily available?
I was in bed with Diane one evening when her 'phone went. I told her to ignore it, but she thought it might be Gary, and she didn't want him to get suspicious. I was mortified for a second when I realised it was Kate 'phoning, panicking that she might somehow know where I was. I'd told her I was going to watch a football match with some mates in the pub, and Diane was videoing the game for me so that I could watch it on fast forward and pick out a few highlights, in case Kate asked me about it. As the two sisters chatted though, it became clear Kate had no idea I was lying in bed right next to Diane and it was just a regular family chinwag. Recklessly, I started stroking Diane's thighs and backside, and she tried to swat my hand away before she let out a sigh and Kate wondered what was going on. I couldn't hear Kate's end of the conversation, but suddenly Diane sat bolt upright and said "Well, do you think you should go and check? Maybe you ought to hang up and call the police." She put her hand over the mouthpiece and hissed at me "Kate said she thought she heard a noise, like a window breaking."
That worried me, and I leaned closer. Diane held the 'phone slightly away from her head so I could hear. Kate was saying, "No it's probably nothing, just next door's cat breaking a milk bottle or something. Hang on, what's that? Oh my God -- who are you? What do you want?" Her voice was rising in panic. Despite myself I snatched the 'phone from Diane's hand and called Kate's name. She didn't seem to hear me and carried on speaking, her voice sounding more alarmed by the second. "Get away, leave me alone! Oh no, please don't hurt me. Please...oh God, don't do that, pleaaaase!" She screamed, and the sound was suddenly cut off as the 'phone went dead at her end. I stared at Diane in horror, my blood turning to ice water in my veins. In a second I had leapt out of bed and was dragging my clothes on. Diane asked if I wanted her to come with me but I completely ignored her as I hurled myself through the bedroom door and half-ran, half-fell down the stairs. Even as I reached the front door I heard Diane telling the emergency operator she wanted the police.
I was four miles from home and I drove like a lunatic, ignoring the speed limit and traffic signals, weaving past other vehicles, praying that the police wouldn't stop me. It seemed clear to me that my wife was suffering at the hands of some psychopath, and I could only imagine what horrors the bastard was putting her through. I'm not religious, but as I drove, wiping tears from my eyes with the back of one hand, I made a solemn promise to God that if Kate was okay I would never be unfaithful to her again as long as I lived,. My tyres squealed as I skidded to a halt outside my home. The only light which appeared to be on in the house was in our bedroom. I threw the front door open and raced up the stairs, screaming Kate's name, terrified by the silence in the house. I burst the bedroom door open and there was my sweet little wife, lying naked and apparently unconscious on the bed, her legs spread wide open. I threw myself down beside her and grabbed her hand to feel for a pulse; then a strong arm locked around my throat and a foul-smelling cloth was smacked over my nose and mouth...
I have no idea how long I was out for, but when I came round I tried to shield my eyes from the bedroom light with my hand and found I couldn't. I twisted my head round and saw that each of my wrists was handcuffed to the bedstead. I also realised with shock that I was completely naked, although covered by our duvet. As I squinted a shadow passed across the light; my eyes finally swam into focus and I saw that it was Kate, leaning over me wearing her dressing gown. I almost burst into tears of sheer relief that she was alive. Of course I still didn't know what the attacker had done to her, let alone why he had stripped me as well as manacling me. Kate reached across me to switch on the bedside light, and a small naked breast passed within inches of my face. As the light beside me came on the main light went off; it must have been the attacker or, please God, the police. Julie gave me a sweet, relaxed smile and said "Hello darling, I am glad you're awake."
There was an edge to her voice, a slight sarcastic note in the way she'd spoken, that worried me. Surely the swine hadn't injected her with drugs or something? She must have seen the concern on my face because she tipped her head back and laughed softly. "Oh don't worry about me Jeff, I'm fine. You need to save your feelings for yourself. So how was it with Diane tonight? Did she let you fuck her up the arse again?" I felt the blood drain from my face. I swallowed hard and told Kate that I didn't know what she was talking about, that I'd been in the pub watching the soccer. She smiled sadly. "So how did you know to come rushing round here within minutes of me raising the alarm? Let me guess -- Diane somehow magically knew where you were and 'phoned the pub, and you rushed straight round here."
Her voice suddenly hardened. "Christ, don't treat me like a fucking idiot anymore. I heard your voice when I 'phoned her, you stupid cunt. Oh, by the way, the police have been and gone. I told them Diane had made a mistake, that I was watching a horror film on DVD and she must have got the wrong end of the stick. They weren't very happy about it, but there you go. So exactly how long have you been fucking my little sister? The sister who always had to have everything I had -- my clothes, my records, my boyfriends, and now my fucking bastard, lying, cheating shit of a husband." She was virtually screaming now. "The sister who always got what she wanted, because she was prettier, and sexier, and more vivacious, and more manipulative than me, who could even wind our parents around her little finger and get them on her side against me. When I married you, and compared you to that Neanderthal she calls a husband, I thought at last I've got one over on her, my loving Jeff would never cheat on me with that obvious little slag. Just shows how stupid I am, doesn't it?"
My mind racing, I tried to reason with her. "Look Katie, it's not like you think, I don't love her; I love you. She seduced me, quite recently actually, and we've only done it together a couple of times. Just undo my wrists and we'll sit down and discuss this like normal rational people. I'm not angry with you, I promise." It never even occurred to me to wonder who her accomplice in this little charade might be.
Kate carried on as if I hadn't spoken, her tone quiet again, almost dreamy. "But then the battery on my mobile 'phone was dead one day, so I borrowed yours. I'm not sure why you hadn't taken it with you that day. And a text message came in. From her. It made it quite clear what you two had been doing together. I nearly confronted you then, but I didn't want to believe it. So I decided I needed to get proof I couldn't delude myself over." I felt a rising sense of foreboding, wondering what she meant. She pointed to the wall at the foot of our bed. "So I got these done."
