How to know if a girl wants a one night stand?

how will I know if a girl want to have sex with me? what proper move do I need 2 do?...
because there are girls hu likes teasing me, seducing me, but I dont know if I'll do the first move... I dont know what's in their mind. is there any body language or facial expression from them that I can see??? from a girls point of view pls. help

ps. its not my girlfriend...

well it sounds like you are a virgin. wait until your in love thats my advice. that is even if you arent a virgin. those girls that are supposedly asking for it will end up hurting you especially if they arent your girlfriend. I dont want to give you useless information and not answer your question cause I hate when people do that so... if you do decide to have sex to tell if a girl is asking for it is really difficult cause sometimes girls can send mixed signals (not all) the best way to tell would be to ask. this is also difficult especially if your not going out with them because they may think you are perverted. if uhave been going out with a girl for a while and do things like bj fingering ect. before you ask her then she probably wont think that about you and break it down to you easy or say yes. if she does reject you then dont worry about it and tell her ull wait. you have your hole life ahead of you dont rush it ^ ^ hope I helped ~kaitlyn~

Blah Blah Blah. Usually if a girl is in the mood they'll squirm, giggle, arch their back and sometimes have really dialated pupils. That's always whenever I knew they were ready for the McLovin lol. But seriously, women usually don't go somewhere unless their going with someone specific and saying to themselves, "I'm going to get some d!ck tonight!"

Women are run on their EMOTIONS so if you want it you got to be smoothe

^^ wow, that shows how much YOU know.
