taste the rainbow fuck

The legendary Taste the Rainbow Fuck is when you bring home a hot little slut, spread her flaps, and stuff and a few bags of skittles. Then you fuck her brains out and leave a huge load of man chowder. You then make her spread her legs wide and you take a big soup spoon and slide it in her coochie and fish out a big gooey spoonful which you feed to her.

Yo bro. Guess what I did to Jennabea last night? I gave her the Taste the Rainbow Fuck and set a new record with four bags of skittles. Then I got her to eat three spoonfuls and she licked it clean! She tasted my rainbow!!!!

taste the rainbow

your nailin a girl while she is on her period (with a condom of course) and you shoot into the condom, then you make her drink the contents out of the condom like it is an oddly shaped glass. 'rainbow' comes from the idea of many different colors all draining into her mouth.

my girlfriend was on her period, and she really wanted to fuck, but i wasnt really feelin the whole blood-thing, so i told her i would only if she would 'taste the rainbow.' that bitch slurped it up like the final parts of a milkshake haha.
