This is a true story from quite a few years back when I was just 19 and although very sexually active, I was unaware just how much of a slut some married women could be. At 19 years I had several girlfriends and one night stands and thought I had hit the jackpot if a girl swallows and didn't imagine any girl or woman got naughtier than that! That was before I really got to know Mary. She was my friend’s Mum and not really attractive at all, and certainly not someone I would have tried to pull. At first I had no interest at all in her and hadn’t even considered her in any sexual way. She was in her late 40’s at the time, married, not that pretty at all but had fairly good size 10-12 figure and big tits, probably a dd cup from my recollection. At the time i had a fairly good job in London, commuting there from Sussex each day, but lived in a bed sit which I hated. I often stayed over at my friends house after our nights out and got in well enough with his parents Mary and Trevor. To cut a long story short my mate moved out with his girlfriend and Mary asked if I wanted to lodge with them, as they now had a room free, could do with the extra cash and knowing I hated my beds sit. It felt a bit weird at first but Trevor worked shifts so Mary and I often spent evening together watching TV if I wasn’t out drinking etc. She was quite flirty although it didn’t register with me at first. At the tine there were no mobiles and internet so porno mags were my wanking material which I hid under the bed. One day soon after moving in Mary told me openly that she had moved them in my wardrobe, finding them when she made my bed. I remember being mortified but she was very friendly about it. She also commented that as I had so many that I just love sex and I found myself telling her that I did. From then on she would ask about my girl friends asking if I’d had sex with them and offering advice etc and I found myself enjoying our chats telling her everything and getting turned on doing so. She would make regular comments about how good looking I was and start to get quite touchy. I guess it was then that I started to think she may want to have sex with me and I started fantasising about fucking her. Not because I fancied her at all but because at that age fucking a teacher or a friends Mum was a very big fantasy. Mary was only flirty when we were alone and completely different when her husband was home. When he was there I wouldn’t even bother watching TV with them, but he was often on nights, and when he was we would be sat on the sofa together. Mary asked if I like massage and often I was sat in front of her her as she massaged my shoulders or had my legs on her lap as she massaged my feet. At first we were dressed in our day clothes watching tv but soon became comfortable in pj’s. Their house was hot so no need for dressing gowns so I was in my pj shorts and t-shirts and Mary wore pj’s but as it was was approaching summer started wearing short nighties. At first she wore a bra but one evening she just stopped wearing one and I couldn’t take my eyes off her swinging tits and big nipples protruding through her flimsy nighty. Our sex chats became more frequent and sexual. She told me one evening that she loved sex far more than her husband did and really missed it as he was rarely interested. By that time I really wanted to fuck her so really sympathised with her but nothing came if it. Looking back I guess either of us making the first nice was a massive one in case the other was offended etc. That night I heard her playing with herself for the first time and I remember wanking furiously listening to her. Her husband was at work so I knew she was alone and could hear the quiet buzzing of a vibrator and her moaning in pleasure. Our rooms were not next to each other but I could hear her through 2 closed doors. The next night, soon after we went to bed I heard her again and this time opened my door a bit and heard her more loudly and walked again. This then happened every night her husband wasn't there. I never ever heard them having sex. After a while Mary started leaving her bedroom door slightly open when she played with herself and I could hear her clearly, as mine would be open too, but nothing was said between us. In the evenings she was now only wearing skimpy nighties with no bra, but she did wear sexy panties which I saw more and more as her nighties got shorter, obviously having bought new ones. Her legs were often now on my lap as I massaged her feet and her legs often parted revealing her lacy panties which I would look at as she watched TV. It is so obvious now she was seducing me but I wasn't confident in taking the final step and she took an eternity in offering me sex. But finally she did. I used to get so turned on hearing her play with herself that one night I risked walking along the creaky hallway and looked through the crack in her door. She had her light in . There was Mary spread eagle on her back on top of her bed feeding a massive vibrator into her hairy cunt, and moaning in ecstasy. I didnt want to get caught so tried sneaking back to bed but the floor creaked and Mary stopped. I knew she heard me and didn’t have a choice but had to open my creaking door to get back into bed. A minute later Mary knocked on my door and asked if I was ok. I had a raging hard on and thought she may be really upset. I knew she would of heard me so I told her I was ok and that I had just needed to use the toilet. She asked if she could come in and I said yes. She sat on my bed with her dressing gown on and asked if I had looked in her room. I nodded and she apologised saying she hoped I wasn’t offended. I replied saying not at all and apologised for looking. She then asked if I liked watching her and I nervously said yes. With that she ran her hand over my covers feeling my body underneath and reached my very hard cock and felt it up and down. She made a comment about it being hard and very big as she carried on rubbing it. She then asked to see it and again I nervously agreed. She put my light on and pulled my duvet down revealing my erect cock on display through my pj shorts and then pulled them down. I lifted my bum for her to do this and my cock came into display. She then told me it was huge (it is a bit bigger than average) and lovely. Her hand was soon rubbing it again. She asked if I wanted to carry on watching her and I eagerly agreed and she took me to her bedroom. Then she kissed me, probing her tongue in my mouth before stripping me naked and telling me to lay on her bed. Then she removed her dressing gown and stood naked showing off her body. Her cunt was obscured by a mound of hair but her big tits looked amazing hanging there with the big erect nipples I had only seen through her nighties. She then took her vibrator from the side of the bed and laid down. Her vibrator was big and I think was probably 10” long and thick. Without saying more she opened her legs and slid it straight back up her wet cunt. For a few minutes she just fucked herself with it but she stared at me and my hard cock whilst she did. She told me to wank myself so I did as I was told and didn’t need telling twice. Mary then brought herself to a shuddering orgasm, as loud, if not louder than she had on the other nights. Taking the vibrator out, I noticed it was soaked as was her hand. We kissed again and she then lowered her mouth onto my cock and started sucking it like a whore. I came within minutes, if not sooner and I shot my load in her mouth and she swallowed the lot. I was then instructed to lick her and dutifully I went down burying my face in her pungent soaking cunt. Her pubes were soaked and she used her fingers to open her hole for me to lick out. She had a very prominent clit and as soon as my tongue started it’s work on her clit she writhed and moaned even louder than before. She became very dominant and demanded I finger her as well. I was amazed how loose her cunt was and four fingers were soon easily inside her finger fucker her gaping cunt hole. It felt like I could get my whole hand in and I had the urge to try so put my fingers and thumb together and proved away, having stopped licking her to concentrate on pleasuring her with my hand. Her Cunt was far more accommodating and wide than any of the girls I had experienced before. Mary loved it and was reaching down pushing my hand in and telling me to get it all in. I couldn’t believe this was happening. Soon my whole hand was in her massive cunt and Mary was crying out in ecstasy telling me to fuck her with my hand and riding it so hard that I couldn’t take it out of I wanted to. Then she orgasmed and gushed all over my hand and soaked the bed. Seconds later she was gagging for more telling me to fuck her. Although my cock is quite big it felt completely lost in her gaping cunt. Mary was really enjoying and had turned into this complete slut, like a completely different person. What came out her mouth was so unlike her. She was telling me to fuck her hard with my massive cock. Her legs were wide in the air in a V shape and she was more agile than I imagined as she grabbed hole of her own ankles. I pumped away inside her for ages but without the feel of a tight cube around my cock I didn’t think I’d ever cum. She then stopped, grabbed some lubricant out of her bed side cabinet and turned over and told me to fuck her up the arse. Her hairy bum was stuck up in the air for me to enter. Again I did as I was told and was soon fucking my mate’s married whore mother up the bum. This was only my second arse fuck and so much better than the first as Mary held her bum cheeks open moaning muffled obscenities as her face was buried into the pillow. Soon with her tight bum hole around my cock I shot my load in her waiting arse. That was the first of many sexual adventures with Mary. I’ve never met anyone else as sexual as her in my life. We had sex everywhere in the house and often outside. She really didn’t care if we were watched and several times we were. She was very dominant in bed and i always did as she commanded. We did things that I hadn’t previously dreamed of. She really got off on me calling her my married whore and a fucking slut. Her favourite fuck was with me and her vibrator in her cunt at the same time. She also loved me fucking her with differed big items. She loved being fucked with vegetables and wine bottles (the wide end!) Although she dominated she really loved me cumming over her face. We had baths and showers and she also liked me pissing over her face and tits. She would also help satisfy my fantasies. My favourite porn mags was “Shaven Ravers” so even shaved her cunt bald for me. My fantasy was to see two women together so for my birthday her younger friend turned up and they put on a full lesbian show before I went on to fuck her friend (and carried in doing so for months after). I don’t think her husband ever knew and am certain her son didn’t. I ended up moving out within the year but I carried on fucking her on and off for several years after that, before we finally lost touch. She would have done even more sexually. She wanted me and another man or men to fuck her at the same time. Being straight I was never up for that, but now wish I had. I’m now into swinging and all sorts of naughty and kinky sex, and she started me on that path. Thank you Mary, I’ve not met anyone naughtier than you or with as wide sopping wet cunt.
