This is a demo of the Coital Alignment Technique (CAT) which has been scientifically shown to help women reach orgasm quickly during lovemaking. This sexual technique is designed to maximize stimulation to the woman's clitoris. It also helps men last longer during sexual intercourse.
By "speeding up" the woman and "slowing down" the man, the coital alignment technique or CAT enhances the chance of simultaneous orgasm during sex.
