I have read techniques on this site numerous times and I have not heard anyone tell this.
Nearly every time I jill I have to have some sorts of anal penetration the more in and out motion the better, it just makes the whole thing better. I start by playing pitching and pulling my nipples and then I start playing with my clit to get that tingling feeling everywhere this usually starts my fantasy. I then take my other hand and insert it into my drippy wet pussy to get my finger all lubed up and I insert into my butt and wiggle it..pull it in and out and stimulate anyway that feels good. If you are someone who often does anal you may want to try two fingers sometimes the bigger the better!
