Wow! Is your gf’s sister hot? How old is she?

Well… it wasn’t the reaction I expected! She smiled at me and told me she was hoping I’d do that!

It may be unethical to do if they're really unwilling, but if I'm just pretending to be unwilling to drink someone's piss, then it's just fun!

Since when is there a rule of how to write a story here? that story was so HOT. 

Interesting read. I guess it’s because I am male but I’ve never noticed men holding themselves when they have to pee and I’ve never done that either.
