As a Japanese woman I can tell you one thing; if your girlfriend loves you and wants you to be her "man" but won't have sex with you until you have some "junk" to do... then this is the best way for her to get it. She'll tease you with big titties, send you sexy messages via text and watch your face as she gets the biggest and most flirty orgasms of her life. In fact, if you want to make her blast off into orgasmic overdrive once and for all, make her perform a "woman's massage" on you..
