The absolute best way is to take a silk scarf or some other fabric and gently tie her wrists together (a blindfold is also a good option) Then you just take your time exploring her with all parts of your body (and I mean all). Start in the non obvious places with as light a touch as you can before flicking (very lightly touching) the more sensitive spots such as her breasts/pubic area. Start in wide arcs and circle motions (leaving the nipples/ vagina) for very last (by now you'll see why she has to be tied down! :) ) Also a sensual massage is a great way - you can find an excellent guide on this very site. If you keep her constantly aroused by doing this it's like an exquisite torture and believe me she'll be more than grateful!

To add to RayzorSharp's comments, I think one of your best "weapons" for teasing is your mouth. Yes, dirty talk done right will really get a woman going! There is a section on this site about it and various other threads as well.

The object is to have her strongly anticipating and waiting for what you'll do next, and also give her a sense that you're in complete control. You have to make her wait and crave the next touch. This will make her very desperate for you to touch her most sensitive areas, of course you should then be verbally intimating that it won't be happening for "quite a while" because you're having so much fun playing with her, etc. Keep her guessing as to when you're going to turn the temperature up!

It's really fun to get a woman to this point because she won't be thinking rationally, and will be willing to reveal interesting things, sexual fantasies she's been thinking about, all kinds of stuff, that is, if you make the right suggestions and help lead her into it. She will be very forthcoming about what's in her mind. You can implant all kinds of suggestions into her head and they will go directly into her subconscious without any processing or filtering. You can use it to suggest other sexual acts, practices, etc that you want to try out in the future. This will often make her more willing to try things when thinking rationally.

Another thing I find to be fun at this point is asking her to beg. Yes, she may actually beg very specifically to be touched in certain ways, especially if she has submissive tendencies. Pay attention to this because you can learn exactly how she wants to be touched in general, what arouses her, etc. When you're satisfied that she's "earned" her release, you can finish the job and give her what she wants.

Ah, fun. :)

well im not sure if u wanna know how to tease her during, or before. but i have some tips on the before part. lightly tickle her along her stomach and sides, like a light touch, the kind where it gives you the chills. and do this along her inner thighs, and do this all while her underwear is still on. (idk if ur going to be taking it off, but incase u are or whatever haha) touch her all around her pelvic area, like along the edges of her underwear. this will make her almost beg for it. while your doing this kiss her neck and around her chest, not just her breasts but like the collarbone area and between her breasts. dont do this for too long, because she will get frustrated haha. then i guess do what u want to or wat you were going to do. have fun! peace~
