Next time your on your back getting some dome from a bitch, push her face down into your nutsack like normal. I guarantee if you let the broad loose, she will sneak her way under your nuts, then she'll proceed to the "Shitoris" and work her way lickin' away at your Carmel Eye. Please believe there is no better feeling and your eye balls will be rolling all over the room due to the exotic flickerin' of joy!
Or another way is to have her suck your dick and nards from behind. She will flip your dong backwards underneath your sack sucking away and then next thing you know she is all up in the cavity...
