I like it when my wife uses her teeth... just a little! Enough to straddle that line between ecstasy and pain Also, to make it easier for my wife to deep throat me, she will lay down on the couch or bed with her head hanging over the edge backwards. It really opens her throat a lot so that she can take all of me in. This is great for those men that are... um, blessed with 8 inches or more. You just slide in, hardly any resistance. Its fantastic.
