Okay then. Lucky I thought ahead.
Here's my boxers before the pissing, they are the same ones I used during the other times I did this.

Here's during the piss, although it's not good quality, you can probably still see the stream of piss. It wasn't alot of piss though.

Here's two pics after the piss, the first pic doesn't show much, but the second one shows it pretty well.

I got done taking a shower afterwards, wearing those boxers still. I'm done doing this for a while, and I'm now wearing dry clothes. Also, to tease some fapping pissfags, I just let a drop go right now. (I would take a picture of it, but these boxers are black)
