Looking for an old story

[dbr720]

This might be a long shot, but I remember reading a story on here at least 10-15 years ago about a guy who accompanied his older sister to a sorority initiation. The sister and pledges were required to consume a lot of beer and do various exercises while holding their pee. Eventually they couldn't hold it and ended up pissing themselves. Finally, they all went swimming in the pool where they were located.

If anyone could find this story for me I would be eternally grateful.
