A rainbow party is an oral sex party it's a gathering where oral sex is performed and rainbow comes from all of the girls put on lipstick and each one puts her mouth around the penis of the gentleman or gentlemen who are there to receive favors and makes a mark um in a different place on the penis hence the term rainbow.

This is where I had painful results. I had a serious reaction to something in the lipstick (the next morning). It caused my penis to swell 2 times its normal erect width (but it wasn't erect). It was also red, inflammed, and itched badly. To get relief, I had to get a shot in my penis (OUCH!) and put a creme on it. It took about a week before it was back to normal. My advice - avoid these partys!
The results from the rainbow party left me with serious pain!

A type of party where a large group of young girls compete to see who can mark their unique lipstick color furthest down on the shaft of a boys penis. Rainbow parties mostly likely do not exist but if they do that would be awsome.
You will not find a pot of gold at the end of rainbow parties, but their is an occasional pearl necklace.

Parties where several girls wear a different color of lipstick then each proceeds to give one or more guys a blow job. The multiple of colors left on each guy's penis resembles a rainbow.
I've been to two rainbow parties now. I didn't last long at the first one seeing all of those girls giving head at the same time with the different lipstick. Julie had me first with yellow lipstick, and I blew my load in her mouth within a minute or two. When my penis was less sensitive a little later, Karen gave me another one with her bright blue lipstick. Since I didn't cum, Pamela took over with her green lipstick when the bell was rung. She asked me to cum on her chest if I needed to, and after I did, I was done for the night.

At the second party, I was more relaxed, and before the end of the night had let each girl leave her mark.

A "rainbow party" is supposed to be a party where girls wear different shades of lipstick and suck a guy off. In actuality, it is a term invented by Oprah and no teen had heard of it until her show in 2004.
Oprah invented rainbow parties so parents can lock up their teens and send them to boarding school.
