Jubei, there is another area called the "cul de sac" which is way deep. That's probably what she was talking about.
Seymoure Butts Pool Party! His videos are my absolute favorites. The girls in his movies are usually very real as opposed to some of the other typical porn girls who are just acting. His girls genuinely seem to be having a good time!
TerraNoble, it's gonna be different for everyone. Most girls like the doggy position...I don't, it hits something painful, like a nerve that sends a shooting pain down my leg...go figure! I also think many girls like the on the back with legs up and knees near their shoulders, spread wide. This position tilts the woman so that there's very good access to the g-spot. The first time we really hit it, I was on top. When I brought home a "love swing" that put me in a great position and he hit it really well. Just remember, it's not straight in, it's upwards, just a little bit inside, not way deep. You could try standing at the edge of the bed with her on her back, her ass just hanging off the edge slightly, legs spread wide open and while you're sliding in and out, hold one hand around the base of your cock to prevent it from going in deep...and aim up a little, kinda like you're massiging her with your dick...you can even pull it all the way out and back in repeatedly...that one drives me insane! It's kinda like having that initial penetration pleasure...it just feels soooo good!
