My wife and I belong to a time-share. Most of the time we reserve a place with two bedrooms just so that we have more room. Anyway, last year my wife decided to invite one of her co-workers to join us. I knew her from the various times that the three of us had gone out together. I can say that we seemed to enjoy each other's company, but there was never any type of close interaction between us. She was simply my wife's friend.

Halfway through our vacation my wife wanted to go to the timeshare's pool for a swim. I wasn't in the mood and her friend doesn't swim, so we stayed behind and started to discuss where the three of us might go to eat that night. Well, for some reason compliments started to be passed, they became sexual, and the next thing you know the two of us are in her bedroom and we're going at it like a couple of rabbits. I swear that I never came so much in my life. (Just writing about it know has got my cock hard enough to hammer nails into a two-by-four.)

It wasn't until my wife's friend had stopped moaning and my cock had stopped throbbing that we realized what we had done. Apologies were flying left and right, and vows were being made to never say a word to anyone. Less than ten minutes after we had cleaned up our mess my wife came back to our unit. My wife never suspected a thing, and when we got home she said that she thought that it was one of the best vacations we had ever taken. She says that she wants her friend to go away with us again.
