When you eat a girl out when she's on her period and your mouth holds a red stain

Last night after I ate Ashley out I checked in the mirror and I had a rainbow patch! Now I can't get this nasty bitch blood out my mouth

Over the Rainbow

During male on male sex; the top pulls out to climax and shoots his load over the head of his partner. Effectively making him tap together his ruby slippers.

The other night Jake was in shock as I let him have it all over the rainbow.
