Seriously though... getting it on in public is one of my all time turns ons... Even the smallest thing like when sitting next to your guy, rubbing his inner thigh as you feel him get hard... its hot, and totally turns me on!
The thrill of getting caught and someone seeing us... its overwhelming!
I love doing it in the car... even just making out in the backseat... I do some of my best work in the back seat!
