What's that milky substance floating in the hot tub?

I still think of this story every time I get in a hot tub.

I was an RA and we had to be at school a week before everyone else for training. We finished training on Friday at about noon and students began showing up Saturday.

So a couple of RA friends and I decided to get a hot tub for the courtyard for Friday afternoon until Saturday. We also got three cases of beer. After the last training session Friday morning, we fired up the hot tub and started drinking. Over the course of the afternoon, more and more RAs showed up. The hot tub was made for six but we had up to ten in at a time.

By dinnertime, we had drank the beer and NOBODY had left to use the restroom. Needless to say, the water was a little warmer and yellowish, but we didn't seem to care.

Several of us decided to skip the dinner and head out to get more beer.

One of the girls with whom I had been flirting most of the week stayed in the hot tub with us and started trying to get me to put my periscope up. She succeeded and continued to wax my dolphin. Whether it was the beer, the hot tub, her expertise or all three, I was unable to contain my load and burst, without anyone knowing … except her.

We decided to leave at that point as we didn't want to wallow in urine and semen. Till this day, I feel a little bad about not telling anyone as they stayed in the hot tub for another couple hours.
