The Cup

The act of when a girl is fingering herself she cups her vaginal juices into her hand and then puts that hand into her partner's mouth (can be a guy or girl) to have them find out what they 'Taste' like

Friend 1: I was having fore play with this chick last night and while she was fingering herself she give me the cup and I LOVED IT!

Friend 2: oh yeah? what did she taste like

Friend 1" CHERRY'S!
