This happened about 15 years ago. It's been a long time so I'm may elaborate on a few things. But it's 100% true and burned into my memory. It's a long story, but needs to be told as such.
Back then, my wife and I had only been married about a year and a half. One of her friends from high school was getting married and my wife and her sister were in the wedding. The wedding was about a 5 hour drive from where we lived, so my sister in law, myself and my wife rode together to the wedding. Sister in law was single at the time.
It was Friday and we were invited to the rehearsal dinner. In true road trip fashion, we had a cooler in the back of the car. Since I was driving, I didn't drink, but my wife and her sister started drinking about a couple hours from where we were going. By the time we pulled into the hotel to change they were feeling real good. My sister in law was staying in the same hotel room. I changed quickly and headed downstairs to wait at the lobby bar so they could get ready...
It was about 20 minutes or more before they came down stairs, which gave me an opportunity to have a few drinks. The lobby of the hotel was in the middle of the hotel. It was a 5 story hotel with the floors all open to the lobby. The doors to the rooms on every floor opened up to the main area (lobby) of the hotel. You could look down from each floor and see the lobby and the bar. As the bar was in the middle as well, it had an actual bar with bar stools and some tables scattered around. I was sitting at the bar, with my back to the lobby, facing the TV's above the bar. When I heard the bartender say "Holy shit, would you get a look at that". I could hear them laughing from the time they left the room, so I knew what was coming. I turned around and there was my wife and sister in law holding hands strolling through the lobby looking for me.
So I guess I should describe them. At this time they were both in there early 20's. My wife was 23 and my sister in law had just turned 21. They both had bodies to dream of. My wife was 5'11", about 150 and had a hot body with slight muscular build and curves that would put you in a trance. My sister in law was about 5'9", about 115 and was a runner. Both had B size breasts and long legs. I fell in love with my wife for her legs. Hell they both had legs that you would dream about at night. And they knew it.
When I saw them, my stomach dropped. That night they were both wearing a one piece dress with spaghetti straps. Both dresses had short skirts that hit them a little higher than mid thigh. My wife's was black and my sister in law's was blue. Both dresses looked almost the same, except the color, which I found interesting.
So the hotel lobby had pretty much shut down. Everyone had focused on the two of them, rightly so. I let them stumble around a little as it was pretty entertaining to watch, not just them, but all the guys in the place drooling over them, especially the bartender. He was a short fat balding guy who would have "paid his years salary to get to touch their legs, for just a second". I know, because he told me, as he didn't know I was with them. I paid the tab, and jokingly said "me too". I got their attention and moved them out the door. As we were walking out the door of the hotel I smiled at him and winked. He just laughed and shook his head, giving me the thumbs up.
We took a cab to the restaurant where the dinner was. Getting in the cab was an experience, as I was able to hold the door for my wife and her sister getting in and getting out of the cab. Both of them unknowingly flashed me a perfect view of their panties. My wife was wearing a bright yellow thong she'd put on that morning, one of my favorites: It had a picture of Pac Man on the triangle of her pussy. Her sister was wearing some sort of sequins thong that slightly sparkles. I could even see each of their ass cheeks at the bottom of the triangle as they stepped into the cab to sit down. Both of them! Neither one of them paid any attention to me looking as they got in, I don't think it would have mattered who was holding the door for them. They were talking away, and definitely feeling the alcohol. The cab driver I believe got a glimpse as well, as he was completely turned around looking at them from the drivers seat, waiting on us to tell him where to go.
When we got to the restaurant, the hostess led us to the party in a back room. It was a large room. Almost looked like a dance hall. And yes, to my hopes, there was an open bar. This was definitely good for me for two reasons, "all I can drink" and "all the girls can drink".
