As for smell, you won't smell unless you havn't changed within 3 hours and that you havn't had a lot to drink
My friend gave me a look one time when we were together in a quiet room. I started to pee and for whatever reason it hissed loudly. Of course, I was just in a diaper and shirt and he was wearing the same, but I think it was the first time either of us had noticed when the other was peeing.
I just grinned at him as I was going and told him he heard nothing.
Has anyone here ever get caught by your parents in the middle of you wetting your diaper or pants? Or has anyone ever gotten caught wetting their swimsuit inside or outside of water?
