Scene opens up in a bustling bar, with about a hundred customers, mostly men, but some women. The waitress behind the bar is busy serving up beer, but chummy with the customers...a guy flirtatiously says he'll give her 5 bucks if she swallows his load..she agrees jokingly...says she'll do if if every male in the bar does it, and she takes a large beer glass down and offers it for the guys to fill it up for her to guzzle.
All the men put down their money, and take turns depositing their load into the glass...
The females present are visibly upset and disgusted that this pretty waitress would agree...
Then, when the glass is full of spunk, the pretty waitress begins to chug, and we see the disgusted looks from the other females present, as our heroine happily drinks down a pint of semem...
