My wife and I are in our late fifties, married for nearly thirty years, kids out of the way, we still enjoy an active sex life and have sex at least three or four times a week. We have fantasies of course, mine a threesome with her and another woman, hers to have sex with another woman. Julie, my wife is 5'4" tall, blonde hair, 36C boobs, slim and still very attractive. I am 6'1" tall, still got all my own hair, fit and average endowment. While we often talk about our fantasies while we are having sex, that is as far, until recently, that they have gone. About a month ago, Julie said she had received a phone call from an old friend of ours called Laura who now lives up in Manchester, and had invited her down to stay with us. Laura is a bit older than us, just turned sixty, she was married a long time ago but for the best part has lived alone. She is tall, very thin with little or no bust, but has beautiful light brown skin, being born of British Asian descent. She can be great fun after a couple of drinks and we have often flirted with each other in the past, including a few snogs and gropes when nobody was around, but never gone any further. I am semi-retired but still run my own private firm as an accountant, mostly working from home, but with a few regular client visits. On the day Laura was arriving I had a late afternoon appointment which I knew would lead into dinner as well, so told Julie to go ahead and eat with Laura that evening and I would have a drink with them when I got home. The meeting went on a lot later than I thought and it was nearly ten when I got home to find them both still up but pretty merry after a couple of bottles of wine. I had a couple of drinks with them but as I was pretty knackered made my excuses and headed off to bed about 11:30. I could still hear them downstairs laughing and giggling as I drifted in and out of a light sleep. I woke suddenly from dozing about 1am, it was quiet downstairs but I soon realised that Julie wasn't in bed. I got up and crept downstairs. The light was still on in the lounge and I fully expected to find them both crashed out after too many drinks. As I quietly pushed the door ajar I couldn't believe the sight that greeted me. There was Julie, completely naked laid out on the sofa, her head tilted over one end rolling from side to side in ecstasy, with an equally as naked Laura with her head buried between Julie's legs. Julie was groaning loudly and pushing her cunt forward into the willing mouth and tongue of Laura who was licking her clit as hard and fast as she could.. My cock was rock hard as I watched them both, and sensing that Julie was very close to exploding into a huge orgasm I pulled the door closed so that only a very thin gap remained for me to peer through and avoid getting caught ! Sure enough Julie came very hard and loudly a few seconds later, writhing under Laura as she came, and groaning in ecstasy. They lay like that for a couple of minutes before Laura slid up Jane's body to her face and the two of them instantly started to kiss passionately. My cock was now raging and I started to wank myself while watching all the action through the thin gap in the door. After a few minutes of kissing they rolled over so Julie was now on top and she slowly started to kiss her way down Laura's body, pausing at her small tits and licking and sucking each one in turn until the nipples stood out like little bullets. She carried on kissing her way down Laura until she reached her pussy, which I was delighted to see was fully shaven, then went to work on her with her tongue. I decided that rather than ruin the experience for Julie that I would leave them to it to enjoy privately, while i crept back up the stairs and into bed, still sporting a hard aching cock. It took a while to get to sleep thinking about what was going on downstairs, and hopefully what was to come the next day. About 4am I felt Julie slip into bed next to me but didn't say anything in the hope that she would think I had slept through what she and Laura had been doing downstairs. When I woke about 8 I got out of bed and went to clean my teeth before going downstairs to make the coffee. I decided that I was going to see if I could now get some of Laura and Julie, so took a Viagra tablet just in case my luck was in. I took the three mugs of coffee upstairs, put two in our room and took the third to Laura's. The door was slightly ajar so I didn't knock but gently pushed it open She was sound asleep, the sheets were only half covering her and I could see that she was completely naked. I was standing there staring at her shaved pussy, all puffy and red from the night before, when she opened her eyes, "Morning" I stammered, "cup of coffee for you " put the cup on the bedside cabinet and went out hoping she hadn't noticed my cock bulging out of my shorts. I slipped into bed next to Julie who was now awake and also completely naked. She ran her hand down over my stomach and squeezed my hard cock " Ummm is that for me ? " she said. She snuggled up to my neck and said "Thank you for last night ", "What do you mean", "Leaving us and letting me fulfil my fantasy" "Was it good ?" "Fantastic" she purred. We lay there for a couple of minutes, Julie rubbing her hand up and down my shaft, until the silence was broken by the sound of Laura going to the bathroom. "Now it's your turn" she whispered in my ear. As she heard Laura coming out of the bathroom, Julie called out to her "Laura my love, come and see what I have got". Laura came into the bedroom, still completely naked, upon which Julie threw back the covers revealing her own naked body with her hand firmly wrapped around my erect cock. Laura lay down next to me and we were immediately at each other snogging like a couple of 18 year olds. Julie slid down the bed and took my cock in her mouth and starting giving me a sensual blowjob. After a couple of minutes of kissing Laura and sucking on her tiny breasts she slid down the bed and for the next five minutes or so they took it in turns to suck my cock and to kiss passionately as they swapped my cock from one mouth to another. "I think it's about time you fucked Laura" Julie said. With that she got off the bed and moved up to the head, she propped her back against the headboard with the pillows behind her and opened her legs as wide as she could fully revealing her shaved fanny. Laura got onto her knees and leant forward and buried her head between Julie's legs, giving me the perfect position to get behind and fuck her doggy style. I ran the the head of my cock up and down her pussy and ass marvelling at the sight of my wife, head thrown back and clearly loving it as Laura devoured her pussy. I slowly slid the full length of my cock into Laura, very wet but also very tight, and started to build up into a steady rhythm, with each thrust forcing her mouth and tongue onto Julie's clit. " Fuck me hard" she shouted as I started to pound my cock into her willing cunt. I looked at Julie who was staring straight into my eyes " Go on fuck her really hard" she said. I kept pounding away but could feel my balls starting to tighten with the usual feeling that I was about to cum. I wasn't the only one, Julie let out a loud scream as a powerful orgasm ripped through her body, whereupon I emptied my load deep inside Laura's cunt. We all collapsed on the bed and laid there breathing heavily as we came back down from our respective orgasms. Julie leaned over and kissed me very passionately and whispered the words "Thank you" before we both took it in turns to kiss Laura. Needless to say we spent the rest of the morning in bed, me watching Julie licking my cum from Laura's cunt and then fucking Julie as she lay on her back with Laura sitting on her face having her clit furiously licked and nibbled to orgasm. The rest of the week was spent enjoying each other's bodies and fucking like people in their twenties, age seemed no barrier to the fun we had ! This is all entirely true, not a figment of my imagination, and carries two very important lessons in life, one, you are never two old for sexy fun, two, make sure you are never without Viagra !!
