As I drove back, I decided that tonight I would not make love with Kate, my wife that night – we were going to fuck and fuck hard. I was already hard before I got to my street, planning all sorts of nasty adventures but then my excitement died and was replaced with a severely pissed off feeling. There on the driveway was Kate's sister's car. Now don't get me wrong – Kate's sister Jane is certainly good looking and I would dearly love to spend some 'quality' time with her. But not tonight. Tonight I wanted Kate. As I walked into the house, I guessed that Jane had had another argument with her husband and was here to have a bitching session with Kate. Past experience had taught me that this simply meant that the pair of them would be 'anti-men' and I stood no chance of sex that night. As I walked into the living room I sensed that I was right as both women stared at me as if I didn't belong in my own house. Kate was on the two seater at the far end of the room whilst Jane was sat on the three piece, near to her sister. Whilst Kate was fully dressed, Jane had obviously had a shower and was wearing her sister's dressing gown. I couldn't help but notice that the gown struggled to hide Jane's breasts but I quickly looked away to avoid any arguments. I sat down on the three seater and looked at Kate, expecting a sorry story of how Jane's husband had treated her poorly again. As expected, the story came out. Kate told me that John, Jane's husband, had said that she was fat and had tits that put him off sex. Whilst Jane wasn't the slimmest of people she could not be called fat and I thought – and not for the first time – that John was a wanker that didn't deserve Jane. Then Jane spoke. "What do you think? Am I fat? Do my tits turn you off sex?" Both women looked at me – this is what men hate! I knew that however I answered, I would be wrong and was in a no win situation. Sod it I thought. They want an answer, they are going to get one! "Well...actually I think you are gorgeous. Your tits are fantastic and I would love to play with them." I was expecting either a put down from them for being cheeky or a ripple of laughter. Instead Kate took me by complete surprise with her reply. "See, I told you. John's a dickhead and he [pointing at me] thinks your tits are great. Show him a bit more" Jane was taken by surprise as much as I was and looked at her sister for confirmation – was this a joke? A dare? Then a wicked grin spread across Jane's face and she turned to me and pulled her gown apart to show her chest. I couldn't help but stare – these were beautiful tits that I wanted to play with. Fuelled by the frustration that I wasn't going to have sex that night, I thought to myself "Fuck it, if Jane's expecting me to back down then she is in for a big shock." I reached over and felt those magnificent breasts. Jane didn't resist and Kate started leant forward to get a better look. "She's got two you know!" said Kate. Now I thought that it was Kate who was expecting me to back down and again I decided to meet the challenge but this time to up the ante. I leant over and kissed Jane's breasts whilst rubbing my thumb over her nipple. Both women gasped and it became obvious that they really had been expecting me to back down. A sudden realisation hit me – whatever I do next, no matter how much either of them disliked it, I could easily defend it by pointing out that they were the ones to start this 'game'. With this new found confidence, I carried on sucking on Jane's nipples but dropped one hand to her crutch. A soft moan escaped her lips as she opened her legs to allow me access. Jane was certainly up for this but what about Kate? A glanced over at Kate and my confidence grew when I saw her smiling, knowing that I was fooling around with her sister in front of her! I moved my hand up Jane's thigh and pushed aside the gown which allowed me access to her crutch – it was silky smooth and had obviously just been shaved. This was an incredible turn on and I really had to hold back from blowing my load right there and then. My fingers found themselves entering this smooth cunt, made easy due to her wetness. All sense went at this point and I pushed two fingers inside her and started to massage her clit with my thumb. Her breath turned to panting and her eyes were tightly closed with continuous moans escaping her lips. By now Kate had moved around so that she could clearly see my hand on her sisters twat, rubbing away frantically as I brought her sister to a loud and obvious orgasm. "Wow! John never gets me off like that!" We all sat down facing each other. Kate didn't move but Jane leant forward and kissed me passionately. I thought that perhaps this event had finished but then those immortal words that sent an electric shock through me... "Your turn" Jane reached over and took my hand, standing me up before kneeling in front of me and undoing my jeans. She pulled out my cock which felt as if it would burst and slowly began to toss me off before suddenly leaning forward and began to suck fervently. I groaned and put my hands on her head, fucking her mouth like there was no tomorrow. After a short time I realised that I had wanted to fuck that night and a fuck was what I was going to have. I pushed Jane onto her back and then turned her over so that her arse was up in the air. I ripped my clothes off and knelt behind Jane. Without any waiting I slipped my cock into her and began to fuck as hard as I could, placing my hands on her hips to pull her towards me as I rammed myself in. Make no mistake, we definitely weren't making love or simply having sex – this was pure and simple fucking. Jane was wailing now and I couldn't tell whether it was in pain or pleasure but to be truthful, I didn't care as all I could think about was cumming inside her. Suddenly it hit me – I was fucking my wife's sister in front of her! I looked around and found Kate without any jeans on, frantically rubbing one hand across her clit and the other was disappearing up her ass. This was such a turn on – not only was I fucking a woman in front of my wife but she was obviously enjoying it and had discovered the joys of ass play. She looked at me intently as she brought herself to orgasm and then offered me her juiced up fingers to lick. I knew I was close to cumming and took my wife's actions as a lead – I pushed one finger, then two inside Jane's ass and began to finger fuck her. She groaned even louder at this point and I kissed Kate passionately. I grunted loudly as I cum, deep inside her sister and I continued to fuck to make sure every last bit of my spunk was buried inside her. Gasping for breath, we sat down in a huddle. No-one spoke as it dawned on us what we had just done. Then Jane broke the silence "Christ Kat, your husband's one hell of a fuck. Do you get that all the time?" We all started giggling at this which relaxed the tension completely and began a series of funny remarks. "You're dribbling on my carpet" "Your husbands mess" "Does John fuck that hard?" "No! I would be bruised to hell if I took that every week" Jane's final comment took my breath away – "Next week...fancy letting your husband watch some proper sisterly love?" Don't Back Down: Sisterly Love It had been two weeks since I had shagged my wife's sister – Jane – in front of her. Two long weeks. The morning after I had fucked Jane, Kate (my wife) was a little nervous around me. I didn't feel guilty in the slightest – after all, Kate had let me do it. To be precise, she had encouraged me to do it and judging by the fact that she had furiously brought herself to a climax whilst I came in her sister, had obviously enjoyed it! That memory will stay with me for a very long time and just thinking about how I hammered Jane from behind whilst kissing Kate made me hard. I knew that remembering that will fuel many wanking sessions – now only if I could get hold of Jane's thong.... I decided to bring the subject up and fuck the consequences. "About last night...are you OK with it? Kate looked surprised. "Actually I was going to ask you. I don't have a problem with it but I am a little embarrassed by what I agreed to do with Jane." This blew me away. You see, at the end of last nights session the girls had agreed on trying 'sisterly love' and I certainly was keen on them trying. "Really! I would love to see that! When can Jane come over?" In my head I thought "Tonight. And tomorrow. And the day after." "I'll ask her later" The rest of the day was very hard – literally. By evening I was desperate for a fuck – Kate was a little shocked when I walked up behind her and slid my hand around her and gripped her crutch. Before she realised what was happening I had pulled her tracksuit bottoms down to reveal her black lace thong. Now, black lace really gets me going (?is that why she wore them?) and seeing these combined with my growing frustration pushed me over the edge. I roughly pushed her down onto her knees and shoved a finger into her from behind. She gasped, a little in excitement and a little in pain as she was dry due to the quickness of my approach. Her dryness however, did not stop me from pushing my cock hard into her in one go. Her gasp turned to a scream of pain but it was too late – I was buried deep into her and I wasn't going to stop. I knew I wouldn't last long and I didn't want to, so I rammed her repeatedly and mercilessly. Seeing her cute little asshole in front of me, I shoved a finger into it. It then hit me that this was the same position that I had fucked her sister the night before, complete with the finger up her ass! "Phone Jane NOW" I commanded. Still on all fours with my cock in her, she reached for the phone. Jane answered quickly. The sisters began the usual small talk when Jane obviously heard what we were doing. I could only hear Kate's replies. "Yes....from behind...just like he had you...yes I am serious about another session...yes, you and me in front of him..." With a loud grunt I shot my load deep inside her – just listening to the two of them planning to fuck in front of me was wild! As I pulled out my cock, a big dollop of spunk dropped out of Kate's pussy which I scooped up, placed it on my cock and offered it to my wife who hungrily lapped up the mixture of our juices. God! Life couldn't get better! A week went past. A very, very frustrating week. And then it was Saturday night. Jane had arrived early and looked stunning – when she sat down, it was hard not to notice the lace topped stockings and the matching bra. Is she wearing a G string or thong wondered? Kate was equally stunning, wearing a blouse that was practically see through revealing breasts shrouded in a purple lace bra – I knew that she would be wearing the matching thong. Just seeing these two women sat in front of me, wearing very erotic lingerie and knowing that we were going to fuck was an unbelievable feeling. The wine had been flowing freely, the lights were dim but still there was a nervous air between the two women as both knew that tonight they would cross a line that many think about but would never do. I knew I had to make the first move and so stood up and walked over to the women, dropping my trousers on the way. "Well, somebody better get my cock out!" I said. Kate moved quickly and gently pulled my boxer shorts off to reveal my manhood, fully erect and shaven. With a slight pause and a giggle, she started to masturbate me slowly. I let this continue, never taking me eyes of Jane who was captivated by Kate's movements. "Suck it" I commanded, looking at Jane. Jane obeyed quickly, kissing the head of my cock before sucking it in. Kate continued with her slow movements and fondled my balls. After a short while, Kate moved closer and started to lick my shaft whilst Jane continued to suck before they exchanged places. Kate's head began to bob up and down and I began to feel that wonderful feeling build up in my balls. Both ladies began to speed up, sensing that I was going to cum when suddenly Jane moved closer to her sister so that both of their mouths were on the end of my dick and were practically kissing each other. At this point I couldn't hold back any longer and let fly a huge dollop of sperm so that both ladies got a mouthful as well as covering around their mouths. I was wrong – life did get better! Kate put her arms around Jane and kissed her neck, then her cheek and then her chin. With each kiss Kate lapped up my sperm and cleaned her sister's face before finally ending up at her lips. This was the moment that I had been waiting for – seeing these two beauties kiss and covered with my sperm was a moment that I had long fantasised about but never imagined would happen. Their kiss was tender with each sister tingling with the excitement of performing such a taboo act but soon became passionate. Each began to fondle her sisters breasts before Jane lowered her hand and began to tug at Kate's skirt. I sat back in a chair to watch this unbelievable show. This skirt was quickly removed and soon Jane's hand was friggin her sister through her lace thong whilst Kate was pulling off her sisters clothes. With clothes now thrown around the room, Kate spent a short time with her hand in her sisters G string before pushing her down so that Jane was lying flat on her back. Kate moved round and sat in front of her and began to pull down the G string to reveal a smooth cunt where the glistening juices were plainly visible. Kate wasted no time before she buried her face in Jane's crutch and began to lick fervently. I had always imagined that such an act between two women would be slow and tender yet in front of me my wife was licking as if her life depended on it. I manoeuvred around so that I could see my wife's arse sticking up whilst she ate out her sister. What a fantastic view! I was very tempted to fuck my wife doggy style at this moment but my cock was still recovering from its workout shortly before – besides, this was a show that I wanted to last as long as possible! Jane began to arch her back and pulled Kate's head firmly into her twat. Her breathing changed to short, sharp gasps before she cried out loudly "Cumming....I'm cumming!". Kate carried on with her tonguing for a few more moments before Jane sat up, eyes closed with a rigid body. Another cry escaped her lips before she let go of her sisters head. "Christ that was good! We should have been fucking each other years ago." "Many years still ahead of us!" On hearing that my dick found another lease of life. They kissed some more and Jane was happy to taste her own juices from Kate's tongue. Kate pulled her sister down and guided Jane's head to her crutch. The carpet was already dark with the wetness of Jane and now Kate was going to add her own juices – I would be smelling their sex for a long time. Jane used her fingers, one at first before slowly pushing two then three fingers into her sister. This went on for a few minutes before Jane lowered her mouth and flicked her tongue across her sisters clit. Kate gasped hard whilst her sister continued to push her fingers in and out her twat. The tongue was moving a lot quicker now and the fingers became a blur with Jane doing her best to pummel her sister's pussy. I realised that I was wanking furiously and decided that I needed a piece of this action. I got on my knees behind Jane and put the tip of my cock at the glistening entrance to her very wet love tunnel. With as big a thrust as possible, I rammed myself into Jane which was made easier by her wetness. She grunted loudly and cried out in pleasure as I relentlessly battered her pussy. Her fingers continued to work my wife's pussy whilst her tongue continued played with the clit. With both hands on her hips, It suddenly occurred to me that this was the exact position where I had fucked Jane one week previously. With this in mind, I began to play with her asshole and not meeting any resistance, pushed two fingers into her and began to finger fuck her ass. All movements began to get quicker and the breathing heavier. We had become one, with all of us concentrating on our own pleasure waiting for that inevitable orgasm to happen. With one final thrust, I emptied my seed deep into Jane's belly and pushed my fingers deep into her ass. Jane screamed out in ecstasy but this scream was drowned out by Kate's. Fuckin fantastic, I thought! We all lay down next to each other in a sweaty mess. The usual banter began... "You're leaking onto my carpet again!" "Your husbands mess...besides who sprayed that?" Jane said, whilst pointing at a very large wet patch underneath Kate's ass. Kate giggled and stood up. " I suppose I had better get more drinks" Jane and I nodded our agreement and I watched Kate's stunning ass walk out the room to the kitchen. Jane leaned over and kissed me. "I enjoyed that. John [her husband] never gets me off like that" "He never has Kate to help!" I said jokingly. "I meant with fingers up my ass" I decided to push my luck a little bit more. "If fingers do that, imagine what my cock could do for you?" Jane paused and then a big grin spread across her lips. "I do imagine...but I don't think we need to involve Kate when we do it next week, do we?"
