look up anything, like your first name:
1. rainbow kissing
a woman performs fellatio on a man and keeps his 'juices' in her mouth, then the man performs cunnilingus on the woman, whilst she is menstruating, and also keeps her 'juices' in his mouth, they then kiss passionately making one big assed sloppery rank-as-fuck mess.
