This story is pure fantasy, but the people in the story are real. I wrote this for my own enjoyment a few years ago. I hope you enjoy.
My wife and I have been married for 20+ years. We are very happily married. My wife, is 5'7" 150 pounds, with long light brown hair, blue eyes, 36c tits and a neatly trimmed pussy. We've been friends with "Bill" for many years. He owns a cabin out in the sticks, no electricity except with a generator. All water is carried in, at least until the well is drilled. It's a cozy place to visit and very dark in the evening.
After not seeing Bill for some time, we finally bump into him and ask about the cabin. He goes there quite often for the peace and quiet. It also give the place a lived in feel, to help avoid unwanted guests. He invites us to visit and we take him up on the deal. We get directions and go our separate ways.
The weekend finally arrives and we make our way to the cabin. Bill is already there. Bill and my wife have a long history of flirting, which turns me on more than I can explain. When we arrive, we all greet each other, a handshake for me and a lingering hug for my wife. She is wearing a pair of loose fitting khaki shorts, brightly colored t-shirt, bra and panties. We all crack open a beer and sit around the campfire making small talk. Bill helps me fire up the grill and I do the cooking. All the while my wife and Bill are chatting and flirting, as usual. He is not trying to hide the fact that he's trying to catch a glimpse up her shorts. It's already early evening when we eat and the sunlight has started to fade. It cools off pretty quickly once the sun fades away, so my wife heads into the cabin to change out of her shorts and into something a bit warmer, usually sweat pants of some sort.
My wife returns a few minutes later wearing the same t-shirt and form-fitting sweat pants tied in the front. I notice right away the lack of panty lines (she hates them). I can only assume she left her panties with her shorts, not uncommon by any means. Since the light is rapidly fading away, my wife and Bill start cleaning up the dinner dishes and putting the food items away. My wife gathers up all the dishes, while Bill grabs the food items. He follows her into the dark cabin.
She puts the dishes into the sink, pours in some water and begins washing them. Bill lights some candles to provide some light. The kitchen area is fairly small, so when Bill goes to put away some of the food, he's right behind my wife standing at the sink. She moves slightly and feels his 'package' gently rubbing past her ass. She pushes back against him a bit more, gently grinding her ass on him. Bill doesn't move, very much enjoying the attention.
She continues to rub against him while washing the dishes. Bill sets his stuff down and grabs her hips. He presses his already hardening cock against her ass. She reaches back with one hand and firmly rubs his hardening cock through his shorts. One of Bill's hands moves up from her hip, under her t-shirt and starts rubbing her tits through her bra. It doesn't take long and he's got her bra pushed up and is fondling both of her tits and gently pinching her nipples. She turns to face him, looks straight into his eyes and slowly lifts her t-shirt up and off. Bill gets his first view of her beautiful tits. He leans forward and begins to lick and suck her nipples. Her bra falls to the floor. She moves her hands to Bill's cock, stroking him through his shorts. He is very hard now. She unbuttons and unzips his shorts, letting them fall to the floor. He is wearing boxers and his big, hard cock is straining against the material. She pushes them down too. Her hands now wrap around his hard, meaty cock. She slowly starts to stroke him with one hand, while fondling his heavy balls with the other.
