I have been married 15 years now, I'm 39, my wife is 35 and her mum, Nancy, is 58.

I've always thought nancy had a fabulous body from the very little I've ever seen and the well hidden bulges.

my wife has always been cold about sex and said she got that from her mum, so I thought fantasies about Nancy would never come true.

That's what makes a good fantasy, what you can never have! One evening I had to drop Nancy home from visiting us. She lives alone and asked if I could check out the empty house for her. She opened the door and as I went past her I accidentally brushed up against her breasts.

I looked at her eyes ready to apologise, expecting a look of anger or embarrassment but she smiled and cheekily said, "Ooh, that felt nice.

" I walked upstairs, she followed, I checked all the rooms and when I walked into her bedroom she said, "There is something I want to show you". She opened a drawer, pulled out a red lacy bra and panties, and asked if I'd help her put them on? My length swelled at the thought of at last getting my hands on that sweet body. ooh, that soft place that I've followed up her stairs so many times would finally be all mine.

as i lifted off her pullover and laid her down on her bed, she said, "you don't know how many times i've dreamed of this happening in this bed!" she made herself comfortable and i took my time, starting at her toes. my fingers stroked her toes, the underside of her feet, my tongue toyed across her toenails and up the top of her foot. as my fingers moved up her ankles, i realised i needed to get her slacks off to enjoy skin on skin up her legs.

i went to her waist, undid them, and pulled them slowly down and off. she lay there smiling at me with big white panties and bra and said, "if she knew this was going to happen tonight she would have had the sexy red ones on already". i went back to her calves with both fingers and tongue spending equal time on both beautiful chunky legs, up over her knees, up her thighs, staying on the outside of them, teasing her, making her wait for the relief that would eventually come for both of us.

across her panties to her belly button, drawing circles around it.

further up her torso, brushing across her bra, running my fingernails under her arms as she raised her hands above her head, sighing deeply. This was going to be worth the 15 year wait. I kissed her neck, softly nibbling while running fingers down the length of her arms. I asked her to flip over onto her tummy and she did.

My fingers went up her arms, across her shoulders to her back. I undid her bra and continued down to her panties where I ran a finger down her crack on the outside of them. Her legs parted, allowing me to feel her soft edges through the sheer fabric of the soaked knickers.

I pulled the elastic back and pushed a finger between her moist lips, finding the personal place and twisting it gently between thumb and forefinger.
