Winding up
Winding up can be defined as Provoking a confrontational situation Often used in a spirit of gleeful malice to annoy or infuriate rivals, or people you just don't like. The most enjoyable form of winding up involves sexual tactics. Almost by definition this means a woman winding up a woman or a man winding up a man - this provides the element of sexual competition. For gay relationships this can be a little more complex.

Where two men are involved the whole thing is likely to end up in violence. With two women, violence is less likely but the process will often become extraordinarily bitchy.
A typical scenario could be rivalry arising from sexual competition or sheer personal dislike. A good proportion of the interchange is likely to be non-verbal, but the encounter will often involve the boyfriend of the victim. For example, the underlying message could be "I don't like you. My body is much better than yours and your boyfriend is going to get an eyeful. Then he will fancy me and you will be pissed off with both of us. But I will win, because I don't fancy him in the least and I am just using him to hurt you."
And it works! Whatever the display might be, it has to be pretty blatant or the innocent dupe of a boyfriend is unlikely to be hooked. It usually involves being much more sexy than the victim, and then rubbing her nose in it in a way which is obvious to her, but not so obvious to the boyfriend who probably already has his cock at half-mast and is so distracted that all he is aware of is your tits or legs or bum or whatever bodily weapon you are bludgeoning her with. At that moment all he he wants to do is fuck you, and he wonders why his girlfriend is so wet and dull in comparison.
Hunting in packs
If you have a willing girl-friend to act as an accomplice things can become really fun. In essence you have a pretty explicit discussion with your girlfriend, talking about rather intimate girly-things. You include your victim in the conversation, but the real target is her boy friend. The subject matter is intended to expose her prejudices or inhibitions while getting her boyfriend sexually excited. Once more the boyfriend is being used; the subject matter is sexy beyond his wildest dreams, and all he can think of is getting off with these two hot chicks rather than having to go home and do the same old boring stuff with his girlfriend.
The potential range of subject matter is almost endless. Nude photographs are guaranteed to get her boyfriend excited - just talk with your girlfriend about the latest hot pics your boyfriends have taken, and then involve him. Ask him what he has been getting up to with your victim. Odds are, it will be precisely nothing, and he will then wonder why his girlfriend is such a prude. Wind it up by offering to show him your pics - he is bound to be interested and your victim will squirm. A more vicious tactic is to say that your boyfriend has posted them on the internet. Even if it is true, don't get too explicit about where to find them. The victim will then be endlessly suspicious that her boyfriend is trawling the web looking for your photos, when he ought to be with her. Adventurous sexual activities are also likely to excite the boyfriend - think of something your victim would never do, and then get him involved in the conversation. Pubic shaving must be number one in most men's fantasies, oral sex would be close behind, and, speaking of behinds, don't neglect the ecstatic orgasms you have when his tongue gently probes beyond your vagina and lingers for minutes on end fluttering around and inside your anus. Do it right, and he might need to change his underwear. She might need to put her head in a bucket!
