Don't be misled by the smallness of the glass.

Fills a reasonably big glass in about a minute whilst also getting quite a lot of piss on the floor.

Fill a Coke glass with piss

Probably the best I've posted for a while. Fills not one but two Coke glasses (though not to the stop) and starts on a third one. Gotta be a litre overall.

Line at the ladies
 

I guess most of you guys have seen this vid of theese hot girls really desperate to go. It is staged, but its definitly godd. After 11 minutes one of them pees hard and noisy for almost 40 secs :)

Which one? Where is the vid?

Piss in bottles
 

These are the last of the ones I have so far from eroprofile. I used the keywords in category piss cup, glass, bottle, bowl, mug, pot, bucket (etc.) basically anything where you can see what the amount is.

Two girls pissing in bottles. Not very big bottles, but filling them easily and seemingly having to stop when the bottles are full even they though have more.

Sexy toilet queue,

What do you think?

Nice gif. This girls capacity is astonishing.

aww where's the video, I wonder.

Pretty sure this is Wendy Taylor from the Piss 'n' Mix series. Type in "piss and mix" site:empflix.com into google and you'll find 7 or 8 of these, each an hour long. All of their girls have seemingly enormous bladders and pee for a minimum of 40 seconds (sometimes over a minute).
