Last winter, my wife Linda and I rented a small cabin in the mountains.

Our friend Sam, who also has a cabin a few miles away, had told Linda and me to let him know when we were running low on firewood, because he had way more than he could possibly use. We decided to take him up on his offer and drove our truck up to visit him, and to pick up a supply of wood.

Sam had lots of extra wood, so he and I chopped and split logs most of the afternoon while Linda made dinner in Sam’s cabin. Linda and I have always been open with each other about our dirty little fantasies. Most of them involve one of us fucking someone else while the other watches. Sam didn’t know it — at least I don’t think he did — but he was the star of several of my wife’s hot stories. What I didn’t know was that she was about to act out one of them.

After dinner and a bottle of wine, we relaxed in the living room in front of the fireplace. It had started to snow and Sam suggested we spend the night, rather than drive back in the dark. I looked at Linda and she said it was a great idea.

I went outside to tie a tarp down over the truck bed to keep the wood dry. Sam had headed upstairs to shower, and Linda was putting away the food. It took me 20 minutes or so to get the wood covered and secured. The temperature was dropping, so I hurried back inside. I didn’t see Linda, but I heard muffled voices coming from upstairs, and the shower running. The voices came from Sam’s bathroom. My heart started racing and my cock thickened, as one of my fantasies involved another guy with my wife in the shower.

Through the clear plastic shower curtain, I could see they were locked in a passionate kiss while he kneaded her firm breasts. I suspected that Linda knew I’d figured out what she was up to because she turned toward the door. Sam had moved his head to her neck and was kissing and licking his way down her breasts. His left hand moved all the way down her slick body to rest between her legs and lightly massage her pussy lips.

As his tongue found and licked an erect nipple, two fingers parted her pussy lips and gently slipped inside. I heard her gasp before she arched her back and spread her legs a bit more, giving him better access as he started slowly pumping his fingers in and out, being sure to brush against her engorged clit in the process.

Linda rocked against his hand, moaning with pleasure as Sam alternately sucked, licked, and nibbled the tips of her sensitive nipples. She suddenly cried out, pulled his head closer to her breast, and started forcefully grinding her crotch into his hand, caught in the spasm of an intense orgasm.

She pulled his head to hers and kissed him deeply. Then she knelt down so his thick cock was level with her mouth. She took most of it between her lips and started bobbing her head while she gently massaged his back and ass with soap. Linda was taking her time, slowly sliding his rock-hard shaft in and out of her mouth. She slyly looked through the curtain at me as she licked his cock like a lollipop, making sure I could see her tongue on every inch of his shaft.

I know that she loves to watch me masturbate, so I pulled out my cock and ran my hand up and down it. While looking at me, she slid two fingers into her pussy and began finger-fucking herself, still maintaining a steady rhythm on Sam. Watching Linda finger herself very nearly caused me to lose control and shoot come all over the place, so I lightened up a little. I could hear that husky moan of hers that means she’s going to come any second. She quickly started bucking on her fingers, thrusting harder and harder, and was losing her concentration on Sam’s cock.

Sam knew it too, and began thrusting a little harder himself. He was just about ready to explode in her mouth. They were both writhing in the shower — Sam pressed against the wall and Linda on her knees with his engorged cock in her mouth and her expert fingers working her pussy.

Suddenly Sam pulled my wife’s head away from his throbbing cock, turned her around, bent her over, and rammed his cock into her hot pussy. She came immediately from that first thrust, and let the world know it. As he was banging the hell out of her, his balls were slapping her so hard that I could hear the beats over the sound of the water. Sam couldn’t control himself any longer. He cried out and filled her snatch with his hot load. He was barely able to hold her up when her knees started to buckle as she came one last time. If I had been touching myself more, I would have lost it right there.

Sam pulled the shower curtain back and stepped out, feigning surprise that I’d been there all along. I looked past him to see Linda beckoning me with her lust-filled eyes. Sam just gave me a smirk and said, “You’ve got about 20 minutes — then it’s my turn again!”
