Is it normal i want to cum in a women's washroom

I would love it if my wife and I were brave enough to do this; I want us to sneak into an empty public ladies' room (at a restaurant, store, mall, whatever) and I pull out my cock and she gives me a vigorous hand job right in front of the sink until I cum all over it, maybe even get some on the mirror. And then I just pull my pants up and we walk out, leaving my cum for someone else to clean up. Is this normal?
