I’m going to keep our names out of this for what should be clear but it’s a story that my wife insists I tell because she is desperate to see what other people think. Personally, although I enjoyed the experience I think we went a little too far and my wife changed complete. I am 56 and my wife is 45, the wife has a great body and loves to wear clothes that show it off but until recently would never and I mean never do anything relating to sex that was out of the usual. We have 2 daughters who went traveling the states for 6 months during a gap year from University. Whilst there they met a girl who I’ll call Lisa. Lisa who is 18 and quite pretty came to stay with us for a few months and in fact went home last Saturday. She is bubbly and funny ad full of life and although she could do with losing a stone or so she is not fat, just needs to lose a little ‘puppy fat’. But what she does have apart from a pretty face is huge tits. I made the mistake of saying in front of my wife and daughters that you could see her coming round the corner about 10 Min before she arrives. My wife said that was inappropriate but my daughters went nuts with me. Buy about a week after she arrived my wife started to change, we would be in bed and she would bring Lisa up in conversation and say something like ‘she does have large breasts doesn’t she’? I would agree and she would comment on how pretty she was but her hand wold wander down to my cock which she would pull out of my shorts and start to massage and we would then have great sex. After a while of this the wife asked (whist we were having sex), ‘can you imagine having a titty fuck with those’ referring to Lisa’s breasts. I told her to behave but she would go on to say stuff like ‘ you would love to fuck her wouldn’t you’? I told her to behave but she would tell me to pretend I was fucking Lisa and of course the sex would get a little wild (but quiet because of the girls). I asked her what had gotten into her and the wife told me that she wasn’t as boring as I thought she was. Then around the second week of Lisa’s visit the girls said they were going out for the evening and staying over at a friend’s house but at the last-minute Lisa decided she was feeling well enough and backed out and insisted that the girls go without her. Lisa ad the wife spend the evening chatting until I went to bed and the wife joined me about an hour later with Lisa in tow. It appears that Lisa found the house creepy and didn’t like to stay on her own. I suggested that she sleeps in with the wife and I go to the spare room but the wife insisted that I stay. The bed was big enough but it was extremely unusual to say the least. The wife on one side with Lisa in the middle with the two of them chatting away. Then the conversation between the two of them changed, the wife said that Lisa wanted to know if I was boring, she screamed and denied saying anything like that. The she says to Lisa ‘ he likes your big tits’ which accompanied another scream and laughter. ‘would you like to see them ‘? Lisa asked pulling her t short off to reveal enormous soft breasts. Lisa was pushed onto her side by the wife and I didn’t have any choice but to suck one of her equally enormous nipples. My wife leaned over and taking my cock out of my shorts started to toss me off. ‘ suck them hard she ordered’ so I did as I was told. Then the wife tugged at my shorts so they went down to my knees before kicking the quilt off and pulling Lisa’s shorts down to reveal a shaved pussy. My wife started giving orders ‘ fuck her, put your cock in her and fuck her’ . Lisa lay on her back and opened her legs By now my wife was sucking the other enormous tit. I asked if she was sure, the wife got angry with me ‘ for fucks sake but your cock in her pussy hole and fuck her now’. I climbed onto our visitor and slid my cock into her pussy and fucker her hard. Her big soft tits bouncing with every thrust. My wife was now naked and feeling her own much smaller firmer tits with one hand and wrapping her fingers round my wet shaft as it slid in as deep as it could into Lisa pussy. The two of them grunted and groaned, the wifes’ tongue going between my mouth and Lisa’s and her tits and for a few seconds after she had ordered me out of Lisa pussy and into my wifes mouth it ran along my rock hard shaft. My usually shy wife was like a woman possessed, even whilst I was fucking Lisa my wife climbed onto of her so that my cock was in Lisa but my wife’s arse was pressing against my belly and both her and I fucked Lisa at the same time, the two of them squeezing tit and rubbing clits. I warned them that I was going to cum but I didn’t get a reaction so I let myself go and filled Lisa with my semen and it was amazing. Lisa had the longest loudest orgasm I have ever seen but my wife ordered me off her before sliding down and grinding pussy on pussy they shagged. My wife had never in all the time I had known her ever indicated that she was into women but fuck did they shag. Squealing, groaning sucking tongue and hard nipples and hands disappearing into pussys, my wife’s small tits wobbling like small jellies but Lisa’s bouncing and swaying all over the place and then the two of them climaxed and it was amazing to watch. By now I was hard again and wasn’t going to be left out so I knelt behind my wife and lifted her ass before sliding my dick into her and shagging her doggy style. It wasn’t long before I was shooting out more cum and my wife wash having one of her mini orgasms which sent Lisa over the top and she joined her. For the next 4 weeks my wife and I were like animals. Ever day if the girls popped out the three of us would fuck. My wife and Lisa would get undressed and assume their favourite position, my wife pressed against the wall of the bedroom with Lisa’s naked body pressed against her, finger shagging each other sucking tongue and tit. I had never had anal sex before but my job was to fuck Lisa’s ass with her as the hottest filling to a sandwich I had ever seen, wet, sweaty skin with big soft milky tits filling my hands with my cock filling her ass with stunning women squealing and groaning until we all cum. I was gutted when she left and don’t expect we will ever get that opportunity again, but we will try and see if we can find another woman to share out little adventure.
