They don't need to thrust because everything is already so sensitive. Check out teen porn movies with adorable 18 years old beauties enjoying cunnilingus from skilled pussy eaters and squirming in vivid orgasm. When his elbows are planted at shoulder width my lover's shoulders are quite wide and he has me open and exposed, working away, there is no way I am able to get away. That, and the taste will be better for the guy. It hurts and will very quickly get us out of the mood.

I melt every time! Guys usually just want to lick all over, but that's never going to get the girl to orgasm anytime soon. I like when my man spreads my legs wide then takes both hands to hold my lips apart while he licks around my pussy, gently flicking my clit, slowly at first then faster and faster until I cum. It doesn't really matter if his tongue moves back and forth, side to side, or in circles. Just because she has cum does not mean that you are done. Clit play gets boring after awhile and many women are too sensitive there anyhow.
