FitBrotha,
nice to see you again! The best position for this is missionary, although i was first shown how to do it doggy, but I was pretty young and flexible then.
In missionary position, once she gets used to you being in her---have her bend left leg so knee is up as high as possible. Right against her chest of even side if possible. Once you go past the curve try to stay there instead of going in and out. It will be painful for her, especially if first time. In this position I take a man of 8.5 or more inches into the "curve". It takes a bigger cock in other positions. This is a time when it is better if your cock is not TOO thick also. But men with 10 to 14 inches are usually VERY thick. Especially if black. Ans yes I have had many that big and the thinnest of them was 2 and a 1/4 inch. thickest was 4 inch (he was 10.5 inch long and could not get past my curve) I would have done ANYTHING for him if possible.
This work in doggy, cowgirl, reverse cowgirl and standing up, as well as missionary. She could aalso stand with back to you. Kepp legs staring and bend over-take you most of the way in. Then when time to go deep, raise the left leg with knee bent and take you past curve. This can be most painful way for your gUrl but also give the greatest pleasure to you big cock. Any more questions please ask.
BTW, love your picture.
Luv, MsGary
