100% moron proof way to make a girl climax. Get your notebook. #1 This one works 99% of the time. While the guy is on top, scoot yourself so your almost underneath her with her legs up on your arms. Then get yourself real close and grab her legs real tight and slide her up and down your without pulling out at all. This way she's rubbing her clit up and down the base of your shaft. If this fails your probably not doing it right, but for the sake of argument. #2 This never fails unless she wants it to. While on top put her legs up in the air and start fucking her real slow in a circular motion. While your doing that one of you needs to be playing with her clit, ( I personally prefer it's her). When she starts getting in a groove lie you chest really tight on hers( this is incredibly intimate and hot) and reach your hands around behind her ass and spread her cheeks. Now this is where it gets tricky, get your finger wet, by this point she better be wet, or you should give up and become a priest, and start circling her asshole. This should do the trick, if she's a freak(which is the way i like it than feel free to stick your finger right up her ass, this will cause massive gushing and guaranteed future sex. Be careful not to spoil them though, they fall in love quickly when you get them off good. I love you guys and hope this helps.
