I apologize in if i missed some info, but were you wearing anything over ur breasts? if so, i wouldnt call it nudity personally. In Canada im pretty sure topless is legal, wish others would follow suit with that kinda thing. From the sounds of it you made alot of effort NOT to get caught or bother people so i dont see harm. but i dont know your local laws so it really doesnt matter what i think lol. either way. hope you had a good time regardless at least!
