Taste the Rainbow

Shoving Skittles up an ass with your dick, and then sucking them out.

I was going to taste the rainbow, but AM/PM raised candy prices to a dollar and I only had 75 cents.

Rainbow Dash

The act of painting your fingers on the hand that you masturbate with, individually with each 1 color of the rainbow (Red, Orange, Yellow Green, Blue, Indigo, Purple). You then proceed to very lightly touch the opening of your penis with each finger, so that it creates a mixture of colors directly on the opening of your penile skin. You then proceed to masturbate as usual, with wet, colorful fingers. Your penis should turn several colors during this process. When you are about to release ejaculatory fluids, rub the tip of your penis once more with the several colors. When your ejaculatory fluids are released from your penis, it should be very colorful and bright.

Guy 1 = Dude, have you ever tried a Rainbow Dash?
Guy 2 = Isn't that from my little pony?
Guy 1 = No the masturbation Rainbow Dash!
Guy 2 = Oh fuck yeah! They are so amazing. I decorated my mother's birthday cake with my multicolored sperm.

taste the rainbow

while most of you are correct in that it is when you eat a girl out while she is on her period you are forgetting one very important step. Whilst you eat her perioding vagina out, she needs to give you head, and as soon as you cum in her mouth, you kiss her and mix the two

My girlfriend is really kinky. Last night she made me taste the rainbow
