Making sex at home, in bedroom is nice, but becomes trite soon. Fresh emotions? I have a cool idea to return to times of your youth when your sex could happen in the most unexpected places!
So, are you ready to take risk of making sex in passing? You can do it by coming into a box of momentary photo in a shop or department store. However choose one which is quite empty, without big masses of people (may be in the morning or late at night). Close the door and arrange erotic show before camera! You may do without sex, even this experience will give you bright emotions. Plus you will have amazing photos! But it's up to you! If you feel advanturous, try to make sex in such a box!
IMHO it's a thrilling way to enjoy a "forbidden fruit"!
