If we're talking at least heavy petting where she came at least once, then all these places. If we're talking penetrative sex where I came in her, only houses/apartments/rooms with windows open (lots), parked cars (lots), the park at night (beach, same thing), and hiking the trails (lots). Lots of petting in moving cars, mostly me driving and giving her orgasms. Getting sucked while driving is an interesting idea, but I expect would be a mood killer in real life. Not interested in getting too sexually excited while operating a killing machine.
