My husband and I regularly go to various adult bookstores in the Portland area - there are a TON of them here.
We found this one with a "Buddy Booth", where you can watch videos, but one side of the room has a window to look through (no glory hole - :-( )
Anyways, we've gone in there a few times, gotten horny looking at the movies and headed back to the buddy booth. Usually, someone immediately goes into the room next door to see what we're going to do. I waste no time in getting completely nude (it's not like I'm wearing that much anyways), and my husband strips down too....we turn on the video and start ************ each other - it doesn't take long before I'm sitting on his lap, facing the window, taking his **** into my *****. I can see the guy in the next room, standing, and stroking his hard ****....it makes me *** when the guy in the other room shoots his load all over the window....sooo hot.
My husband loves to *** inside me, and let the guy see my ******** up close - then he cleans me up....all while we have an audience.
A few times, I've walked out of the room completely nude, except for my heels, through the bookstore part, and out to the car - with my husband completely clothed....by the time we get to the car, he's hard again and ***** me again....
...may have to repeat this this weekend!
