When I was 17 and a willing and able (or semi-able) female presented herself to me, I cared fuckall about where we were or who was around us.
In 8th grade I got a double handjob (one chick was a plumper) on a class field trip in the back of a bus where about 8 nuns and several mothers (included my own) were sitting in the front.
me and my lady friend took a stroll down to the park yesturday and out in the open there were these two kids probably 17 or 18 gettin their hardcore bang on.....20 yards away two children fed bread to the geese
