Spice it up! The 8 Best Places For A Quickie from askmen.com
1- Elevator: An elevator is high on our list of eight locations for a quickie, although going up or down several floors isn't usually sufficient time get things done. We recommend you stall the elevator given that you don't trigger any alarms by doing so, unless you enjoy getting caught.
2- Movie theater: You may think this one has been done to death but getting busy in a movie theater is always a thrilling experience, and there's less chance of getting caught
3- Back of a club/restaurant: Being out on a hot date talking about hot things with a hot girl will usually excite you, so if both of you are up for it, head to the darkest part of a nightclub, or even the bathroom, and get your groove on.
4- Stairwell: If your roommate's home or you and your girlfriend only have 10 minutes to spare for a lunch date, head to the stairwell of a building with an elevator, preferably on a really high floor, and go crazy for a few minutes.
5- Car: So it's not an original idea but a quickie in the car at a location where you won't be arrested for public indecency can be a very memorable experience.
6- Alley: Before you begin envisioning rats and drunks, picture an alley behind a restaurant that isn't as filthy as those you see in movies. Ideally, she'd be wearing a skirt and the both of you could head to an alleyway just after dinner and before the show. Now that's what we call an intermission.
7- Office: Whether it's a babe you've been eyeing at work or your girl shows up in nothing but a trench coat and heels, sometimes sex at the office is part of what makes life that much better. Make it part of your daily tasks, if possible.
8- Dressing room: How many times has your girl got you all hot and bothered while she's changing in the dressing room of a clothing store? Well, why not add some kick to the tedious task of shopping by sneaking into the changing room with her and have some fun.
