rainbow brite 

The rainbow brite is a sexual act that involves a man consuming between 1/2 and 1 bags of skittles, almost as an act of foreplay. After eating the skittles, the man spits into his (female) partner's vagina and/or onto his penis. The two then make sweet love for 3-19 minutes. Just as the man is about to climax, however, he removes his now multicolored penis from his partner's vagina and puts it in her mouth. The multicolored and sweet tasting penis remains in the girls mouth as the man climaxes and implores his partner to "TASTE THE RAINBOW" at the top of his lungs.

last night. with your mom. i did the rainbow brite.
