The couple Joanna and Tim

Her mind-blowing move: the tongue teaser

"There's this trick I do to Tim's tongue that drives him absolutely out of his mind. It starts with a slow, sensual kiss, during which I slide my tongue in and out of his mouth to build the arousal. Then I slowly pull my tongue back, as if I'm about to stop--but I lick his lips a little on the way out to entice him into my mouth again. Once his tongue is back inside, I wrap my lips around it entirely and begin to suck, starting with slow, gentle motions, then alternating with faster, harder ones. After a few seconds, I resume our standard--but still very sexy--smooch, then I go back to sucking every few minutes. His breathing gets faster, and he starts pulling me as close to him as he can. It's such a suggestive move that I know he's thinking about me going down on more than just his tongue! And the fact that I make him so crazy with desire makes me want to jump him."

Why he flips: "This is such a different way of kissing. As soon as Joanna starts flowing into that gentle rhythm of hers, it's Erection City! All I can think about is how great it feels--and where I'd really like her mouth to be. Luckily, she's always been able to read me like a book. Just when I can't take the anticipation anymore, she works her way down to ground zero and launches my rocket."
