I’ve read a few stories about fathers fucking their daughter in law and to begin with I thought it was either very rare or bullshit but when I confided in a very close friend he opened up about how he was fucking his sons girlfriend and had fucked most of them (he is a bit of a ladies man / flirt and very good looking). So here my story. My wife and I are in our mid 40’s and still have a great sex life, we make love three or four times a week, but we had hinted about spicing things up. The farthest we had gone was posting naked photos of the wife on a certain ‘hot wives’ web site with great (although dirty) reviews. So, last weekend my son and his soon to be wife stayed over for us all to go our Christmas shopping and the young lady in question who I will refer to as ‘T’ is perfect. She has a great figure, not too big breasts, is tall with long strawberry blond hair. She is funny and we all get on very well. My son decided to play football with his mates before meeting us in town so the three of us where in the house on our own. The night before, my wife had said something about how she ‘would’ if she was into girls. It was quite random, so I asked her to clarify what she meant. My usually reasonably quiet wife said ‘ if I was a lesbian I would fuck her’. I was so shocked I sat bolt upright in bed and was speechless which she found hilarious. Of course, I pushed her on it and she openly admitted that if she was inclined to have sex with a woman T is the sort of women she would ‘do it’ with. She went on to tell me that if she wasn’t going to marry our son she wouldn’t mind letting me fuck her if she was in there as well. I tell you now, it led so an hour of great sex with my wife and I talking dirty about T. She pretended that ‘T’ was eating her pussy instead of me and I had to pretend it was T sucking my cock whilst my wife gagged on my shaft. The next morning my son left early, my wife and I and T had breakfast after which T went for a shower. My wife being wicked suggested I get in with her but of course that was not going to happen. I waited my turn to shower after T and the wife so was still in my dressing gown 30 min later when T had had her shower and the wife had finished hers. I don’t wear anything to bed, so I was naked under my dressing gown sitting on the bed reading messages on my phone when the wife and T walked in hand in hand. I started getting hard straight away at the site of T in a very tight silk gown clinging to her still wet figure. Her nipples pushing through the silk which hugged her breast. I remember thinking that she may as not be wearing it because it was so tight. I jumped up and started to walk out. My wife stopped me telling me ‘not just yet’. She then told T that I didn’t wear anything to bed and that she bet I was getting a hard on right now. T laughed. The three of us were standing less than a foot from each other, T was looking at me with a slight grin. My wife put her hand on my cock which was still hiding under the dressing gown. ‘yep’ she said, ‘ I was right, he’s hard’. T giggled again as the wife opened my gown. I tried to cover myself but was told off so when she opened it the second time I just stood there. The wife pulled it to the floor so now I was standing in front of my future daughter in law completely naked, my cock now fully erect. My wife moved closer and started to massage my shaft, ‘isn’t it big’ she asked T who was staring at my shaft and my wife’s slow massaging. She said something like ‘very big’. My wife stopped tossing me off and grabbed T’s hand and put it on my cock. She gripped it and started to slowly toss me off looking at it as though it was the first time she had seen a cock and I am sure it wasn’t. What happened next was almost in slow motion. My wife undid the silk cord around T’s gown and pulled it to the floor causing T to let go of my cock for a second. I didn’t think it was possible for me to get harder but fuck did I. T ‘s body was perfect. Her tits were small but hard, her nipples big and red, her stomach flat and her pussy smooth and she was standing so close to me her leg touched mine. My wife was now also naked and standing behind T, her arms wrapped around her cupping one of her breasts. ‘It tastes nice as well’ she told her. T looked behind her at my wife who smiled and nodded. T slowly sank to the floor and my shaft disappeared into her mouth. I could feel her tongue running up and down my shaft, flicking the slit at the end of my cock before it slid back into her mouth. My wife’s tongue entered my mouth for a second before she pulled back and said, ‘happy birthday’. I reminded her that my birthday wasn’t until Feb next year. The wife laughed and said that didn’t matter and put her hand on T head, ‘ does it dear’ she said to T. T pulled her mouth from my cock and said ‘no’ followed by ‘can we fuck now’. We made the short walk to the bed. T lay on her back and looked at us, biting her lip. I didn’t; know how the fuck she could look hotter than when I first saw her naked but she did right now. I lay beside her and put her hard nipple in my mouth. My wife told me to eat her pussy and I obliged. It was sweet and wet. T moaned, I looked up at she was gripping her own nipples whilst my wife and her sucked each other’s mouth’s. All I wanted to do was fuck her hard but I knew I had to bide my time. I put my fingers into her pussy along with my tongue listening to T moan whilst snogging my wife. They stopped sucking each others faces long enough for my wife to put her larger breast into T mouth for her to suck which she did for quite a while until my wife returned to favour and sucked her tiny tits hard. T stopped writhing and moaning and asked my wife, ‘can he fuck me now’. The wife looked down at me ‘fuck her but be gentle’. I quickly worked my way up her perfect body having a quick titty suck before I pushed my cock into her tight wet pussy. T moaned and arched her back and I did as I was told, I pumped her pussy slowly, my wife and I sharing her mouth and tits. I managed slow for quite some time with T shaking and seeming to cum several times until she gasped and pleaded with me to fuck her hard begging me to make her cum again. I became rougher with her, fucking her hard and lifting her bum up so I could kneel and fuck her at the same time, her tiny sweaty tits wobbling, my wife fingering herself, sweating with her face bright red, moaning and quivering. I had T on her knees then I let her ride me before pushing her onto her back to fuck her missionary again. Then I couldn’t hang on any longer, as T cried out that she was cumming I emptied my balls into her pussy and all three of us came hard. I managed to cum several times inside my future daughter in law before my cock slid out and I lay next to her exhausted my wet dick still semi hard. My wife however wasn’t ready to stop. I had never considered my wife to be BI sexual but she climbed onto T and bending and twisting herself she managed to go from sucking T’s pert tits to her beautiful mouth whilst the two of them grinded pussies. I lay there and watched the two of them fuck like hardened lesbians, crying out until T came again and then begged her to stop telling my wife that she couldn’t take any more. With one last scream my wife froze still gripping T’s breast then collapsed next to her, the three of us panting. After some time T said ‘than was amazing, please, we have to do that again’. Then getting up said ‘but not now’ and sliding off the bed told is she just couldn’t right now. I turned to my wife and said that I hopped she was on the pill. She told me that she was, ‘I checked’. I asked her how she managed to get that to happen, and was told that T had said how lucky they both were and when my wife joked about some ‘secret fun’ T was all for it and it was her that suggested they do it now. That was last weekend and I’ve fucked T once since, bent over a chair fucking her hard doggy style whilst my son was still in bed and the wife was making breakfast the next day. She knew what we had just done and was annoyed that she wasn’t invited. I don’t expect that to be the last time but I do feel guilty but that won’t stop me, we just have to be careful not to get caught.
