Kissing is probably the most important part of foreplay or even sex for that matter. Not just kissing her mouth either, there's a broad spectrum to choose from -- her entire body. Use your lips, tongue and teeth to show her that the night is hers and you don't plan to neglect any part of her.
Don't be shy; kiss her ears, eyelids, neck, throat, shoulders, breasts, stomach, back, inner thighs, feet, and of course, her mouth. There are no boundaries, so dive in with your mouth and show her that smiling is the second best thing you can do with it. When you do kiss her mouth, don't just shove your tongue inside and try to pretzel it around hers. Lick her lips with your tongue, gently suck on her upper lip, then her bottom lip, and when you finally do stick it inside (yes, we're still talking about your tongue), let her tongue find yours. Let the tips greet each other until intensity kicks in and she lets out a "penetrate me" moan.
Shocker Kiss : During the kiss, gently but suddenly suck the air in from your partner's mouth for a quick and sexy change-up.
Lemon Drop Kiss : Suck on a lemon (or lime) before kissing to give your lover a tangy experience.
Icy Kiss : Put some ice cream, Popsicle or ice in your mouth right before you kiss your sweetie to literally give him or her chills.
Upside Down Kiss : Think about the scene from Spiderman where Spiderman and Mary Jane kiss while he's hanging upside-down. Find a way to line up your bodies so your mouths align in a different arrangement than they usually do and then explore from there.
You can give her oral pleasure amid foreplay; she'll definitely feel the pluses in that. As well, the area called the perineum, which is located between the anus and the vagina, is a very sensitive spot. But you can also use your erect penis in that area and as a tool for the pre-sex session. Ahh, teasing a woman is probably one of the most exciting things in the world.
While she's lying down, hold your penis with your hand and use the head to rub her clitoris. Circle her vagina and make like you're going in for the kill, but don't. Look her in the eyes while you slowly stroke her vagina, from her clitoris down to her perineum and ask her, "What do you want me to do with it?"
