My wife and I have always been open about sex, telling each other our fantasies, me telling her how I would love a threesome and Lisa ( my wife) telling me how she would love to have sex with a stranger and have me watch but also how she would love to watch me ‘have’ Amanda (more about her in a sec) , but she has never mentioned, not once, being with another woman so you will understand my shock ( a nice shock) when I caught her with her friend Amanda. Lisa ( my wife) is 26, she’s slim, has copper coloured, pale skin with freckles all over her body (Size 8). Her breasts are small and firm. Amanda, her best friend is about the same height, (5’10”), short black hair. Her body is bigger than Lisa’s at about a size 12 but she carried it well and her tits, well let’s just hazard a guess at DD ish and where as my wife’s hardly move when she walks, Lisa’s bounce. In fact Amanda had often joked that she loved Lisa’s tits and wanted some like hers and had mentioned having a reduction. I made the mistake of telling her that they were fine as they were to which she laughed and pushed her cleavage in my face telling my wife that she reckoned I wanted to ‘suck em’. It started about 6 months ago at Amanda’s birthday party which was being held in a local club. Lisa and Amanda had their big group of hot friends there with husbands / partners, Amanda’s husband was there but pissed as usual. I had in my mind what my wife had said about her wanting to watch me fuck Amanda and wondered if it would ever happen. I chatted with the boy’s but couldn’t help but watch my wife at the other end of the room being hit on and wondering if she would ever act on her fantasy. I also watched Amanda and her dancing and laughing, watching Amanda’s big tits bounce hoping they would poo out (which didn’t happen). Then, at about 2am I was ready to go, (lightweight I know). A lot of people had left but I couldn’t find my wife. I had a horrible feeling that she had gotten drunk and was with her stranger. I had visions in my head of my wife say on a table somewhere, her legs round a strangers waist and his cock in her with his hands grabbing her tits but I knew she wouldn’t do it behind my back but I still had to find her to make sure. The place that the party was held had a lot of rooms for functions and so on and it took me a good 20 minutes to find her. I passed a door with ‘staff only’ on it. As I did, I heard a giggle that sounded like my wife and a ‘fuck’ which sounded a lot like Amanda. I carefully opened the door expecting to find Amanda shagging some guy. The light was very dim, but I could make out my wife’s copper/ ginger hair. Her back was to me, but it was bare. I could make out her freckled back and her white thong. I was about to go nutt’s thinking that she was with another guy and put the light on. Amanda shouted for me to put the light out and lock the fucking door before her head went down again. I locked the door and moved closer. There was a tiny light that highlighted a fire extinguisher. For some reason and for a brief second, I wondered why they had one in a store cupboard, but my mind soon went back to my wife. I moved to her side, the two of them barely illuminated by the small light. Amanda was bent over, my wife’s breast in her mouth, Amanda’s hand between her legs clearly fingering my wife’s pussy. Lisa was quietly panting, her hands gripping Amanda’s bare breasts, her dress on the floor. Amanda sat up and grabbing my wife’s hand put it down her knickers. Now the two of them were rubbing each other’s pussies whilst sucking each other’s face. Amanda pulled back for a moment to tell me how amazing my wifes tits were and reminding me that she wanted tits like that before going back to put her tongue on my wife’s mouth, the two of them finger fucking each other at the same time moaning. Lisa stopped, grabbed my arm and pulled me closer panting that she was sorry but asking me to kiss her. I did as she asked and whilst I did my wife stopped fingering her friend and pulled the zip down on my trousers struggling to undo my belt. My hands were all over her, feeling her tits and her arse. I went to help undo my belt buy Amanda beat me to it and seconds later my jeans were on the floor and the two of them almost fighting to toss me off whilst returning to suck each other’s faces. There were arms and hands everywhere, feeling each other. Lisa pulled back and begged me to fuck her telling me that she was going to cum and wanted to cum with me inside her. I bent my wife over a shelf, pulled her thong to one wide and pushed my cock into her familiar tight pussy. I fucked her hard but couldn’t help look at Amanda, she had one leg on a chair and was leaning against another shelf shagging herself with her hand, her big tits swaying watching me fuck my wife, all the time grunting ‘oh fuck’ over and over telling us or herself that this was so good. Lisa shook and arched her back and came hard making a long low grunting noise that I knew meant she was Cumming hard. I couldn’t last any longer and filled my wife with my cum, my lower stomach slapping against her arse. But it was what my wife pleaded with me to do next that shocked me. I pulled myself out of her pussy and put one hand on a shelf to catch my breath. Lisa stood up said ‘that was good, fuck that was good’ and looked at her friend before pushing us together. ‘Fuck her hard’ she pleaded, kissing us both on the mouth. There was a table next to a stack of boxes. Lisa pulled Amanda and told her to sit down. Amanda was now naked, her knickers had fallen off, her big soft tits glistening in the low light. Lisa pulled me over ‘ fuck her hard, make her cum for me’ . I stood in between Amanda’s legs which started to close round me. I bent down and sucked her big dark nipples hard getting as much of her big soft tits in my mouth as I could and shoved my still hard cock in her pussy and I fucked her hard. The table banging against the wall, my wife wrapping her arms round me. She lifted my shirt so her tits would press against me and was thrusting matched mine, it was as though she was fucking Amanda and I imagined her wearing a big rubber cock fucking her friend except it was my cock in Amanda. I shagged her hard, her tits swinging. I noticed her legs where no longer gripping me but were raised up to my shoulders. My wife pleading with me to keep going and to make her cum hard, she didn’t; stop talking to me the whole time ‘ fuck her baby, fuck her for me, make her cum hard like me’. I saw that my wife had Amanda ankles in her hands and was lifting her legs up. Amanda’s head fell back and she banged it against the fall. I thought that she had hurt herself but all she said was that she was Cumming, ‘oh fuck I’m Cumming’ before looking to one side and begging my wife ‘ oh fuck baby, let him cum inside me please’. She was talking to Lisa who pressed against me hard, her solid nipples pressing against my back. My wife barked instructions in my ear, ‘cum inside her baby, make her cum’ telling me to empty my balls in her pussy. I did as I was told and the three of us climaxed, Amanda shaking and crying, my wife biting my back (literally) putting her finger in my ass whilst her hand felt my wet cock and of course me, Cumming for the second time in about 20 minutes bit this time in an another woman. The three of us laughed like school kids who had done something naughty. We dressed and quietly, one by one crept out of the storeroom and home. For the next month I would spend my Saturday nights laying on my back, first my wife then Amanda riding my shaft, her big tits swinging, my only instructions where to make them both cum. I had my threesome lots of times, fucking two hot women and watching them enjoying each other’s bodies, sadly no full on pussy grinding though. I can’t wait for it to start again but Lisa has reminded me that she still wants her stranger.
