Judging by the amount of clothing worn by some participants, they must have had the heat turned off. What fun is that?

Judging from the pictures, the event looks to have been a bit light on lads.

HOW DO I KEEP MISSING THIS STUFF?!

I live in Mountain View. I sometimes think about moving to the city because life down here is so boring.

Wow... wee bit of a female participant bias in these pictures, or what?
Looks like a fun event though. Good for all these people for not hiding their sexuality away in a tiny locked-up box of shame.

Here's a question - where the fuck is the peen? I went through those pictures to see a whole bunch of tits and vaginas? We don't even see the dick of the winner? JIP.

Ok, you'll show titties but no dick?
Fuck that!
You could've compromised with balls, but no. Boooo!!!!

Most of the time I really enjoy living here. Then there are times I want to run away screaming in disgust. This is one of those times.

This is great. What better way to encourage and inspire those who truly need or even just enjoy their orgasm to do so. Events like this are so positive in helping us all loosen up, feel less self-conscious, and masturbate. They help break that chain of irrational guilt and motivate us to ejaculate or orgasm more often like we desire and need- like nature intended. It's inpired me.
