Just look at the expression on these girls faces in the photos you've already posted... There's no question that they are experiencing an orgasm with the black guy they are with.....
But getting back to the question, I need to first ask a question of my own.. Just how many of you reading this has had sex with someone and they finished long before you did, leaving you incomplete and unsatisfied..? That's the way it was with me every time I had sex with every white guy I was ever with, including my ex-husband. The only way he could get me off was through oral sex and even then, it still left me wanting more and kept me wondering, is this all it is..?.. Well, this was the way it was until my first black experience. I wish I had the ability to express my true feelings but I just can't find the words to make any of you reading this to understand. In fact, sometimes I wonder if I understand it myself but very, very surprisingly, my first time with a black guy was an experience that far exceeded all my expectations. Again, I don't know what it was but this guy was able to find every sensational part in my body and crazy as it was, I know I had 3 orgasm the first time we had sex...amazingly, the first orgasm came as early as it was when I felt him completely in me to the hilt and he just remained there for a few minutes while I was having this very powerful orgasm.. I could actually feel the throbbing of his cock while I seemed to go into some kind of convulsions...I couldn't believe I finally had my first orgasm through cock penatration and even more surprisingly was when he started moving, it didn't take long before I was achieving another...again, with my arms tightly around his neck and my legs tightly around his waist, I was gripping him like a vice and he sensed my feeling this second orgasm and somewhat slowed for me to feel it completely...once he knew I had come down from my second explosion, he started moving again but this time, his movements became more powerful, and knowing he couldn't hold it any longer, he finally cum in me while at the same time, I was having another with him also... Like nothing in my past sexual experiences, I was completely drained by this gorgeous black man and it didn't take rocket sience to know this is the way it should be. Like I heard someone expression..."it's not over til we both get our cookies.." I'm sure my facial expressions was much like the ones in these photos.. Again, this doesn't tell you the HOW and WHY all this suddenly happened to me but as time past, I have found that I have an orgasm, (most of the time multiple-orgasms,) with each and every black guy I've ever been with..
I'm not trying to speak for anyone other than myself but at least that's the way it's been with me and why I've been black exclusive almost since my first..
