My name is Pete and i'm 22 i'm 5' 10" tall and athletic, and if l say so myself I'm quite well endowed being 9" erect and 5 and half" circumference.I keep myself fit as l'm down the gym most nights after work. Now me and my work colleague Mike who is 59 and 5' 7" tall and slightly grey and balding. We were just chatting at lunch time when he said "Do you have any sexual fantasies". After a moment l said "Well I've always liked the thought of fucking an older woman". "Wow how old" Mike said. "well to be honest,l quite like the thought of fucking a granny". The next day at lunch Mike said .."I've a proposition for you, me and my wife have been talking and she says she fancies being fucked by a younger man even though it's just a fantasy at the moment. and l quite get turned on by the thought of another man fucking her".... So arrangements were made to go around on the Friday night.... Friday... Mike opened the door and we made our way into the lounge Denise was 57 about 5' 2" dark hair and slim with a fair pair of tits, she looked quite Mediterranean. She sat on the sofa in a short dress unbuttoned and showing a lot of thigh and her ample cleavage. We all sat making idle chit chat and drinking, after we'd had, quite a few drinks Mike said "I told Denise about what we'd discussed, and she is up for it". So Mike suggested Denise should go up to the bedroom first, and l was to follow a few minutes latter. I opened the bedroom door to find Denise laying on the bed in a white bra and panties, they really stood out against her tanned skin, she looked very sexy. As I stripped off she looked up and said "wow aren't l a lucky old woman you big boy" l got onto the bed next to her, we started to kiss and soon our tongues were exploring each others mouths. She placed her hand gently on my now erect cock, and started to rub it. l slipped my hand between her legs and started to rub her fanny through her silky white panties, it wasn't long before l could feel her fanny juices seeping through. l undone her bra and started to caress her nipples they were now rock hard. I slipped my hand inside her panties and eased them down, she had a lovely shaved pussy, I moved down to gently kiss her clit which was quite pronounced, as l sucked her clit she made gently moaning noises. She whispered "fuck me now, fuck me hard with that big cock". As I entered her she gave out a gasp "that's so big" she said. As l was fucking her and heard a noise l looked up there stood Mike naked with a hard on. "Don't mind me, you two have fun" he said. By now Denise was squealing with delight as l fucked her, and l hadn't put all of my cock in her yet. l then started to pump her deeper and deeper "Oh yes l want it all" she shrilled. l was now fully in her wet cunt, after a while she said "l'm cumming l'm cumming " l started to pump her faster and deeper. "Oh god I've cum" she said, as l pulled my cock out, it felt as if she had pissed the bed as there was so much of it, and l hadn't cum yet. Denise looked up and said "no offence Mike but I've never been shagged like that in my life. l want you to tell me how dirty l am". "non taken, l loved every minute myself, you dirty, dirty old woman, letting a mere boy fuck you"was his reply. Mike had wanked in Denise's panties and was cleaning himself up, he stood up looked at the pair of us on the bed bed and said "l'm going down now you two enjoy yourselves, stay up as long as you like" l was laying on my back still semi erect Denise lay next to me she whispered in my ear "you have made a fantasy come true for an old woman. I've never seen such a big cock let alone been shagged by one. Mike never lasts more than a couple of minutes". After about ten minutes Denise leaned across and said started to gently kiss my cock, as she expertly used her tongue to caress it, l soon became hard again. Denise leaned over and whispered "Do you want to fuck an old woman" l was positioned on my back she climbed on top of me, she was still soaking wet. we started to fuck again this time my cock slipped straight in, as l was pumping her harder and harder l could see her tits bouncing up and down, she leaned over for me to suck them. After about ten minutes of pure fucking, Denise called out "tell me what a slut l am" l could feel l was closer to cumming so l said " you dirty old slut this boy's going to fill your old cunt with hot spunk" Yes Yes fill me fill me". l shot my load deep inside her. I stayed all night and we did fuck one more time and again the next morning. Denise cooked both Mike and myself a full English breakfast. l now call around to Denise and Mikes every weekend, but now instead of wanking himself off Mike get to fuck Denise after l have cum inside her. He loves being cuckold, as l am always telling him at work how I'm going to fuck Denise hard and fill her old cunt with my youthful spunk. He then has to go to the toilet to have a wank. l hope we can keep this arrangement for some time.
