Im a very straight young man and my long time bi girlfriend would like to see me suck another man's cock. I said no at first but now Im realizing that I have always been currious what it would be like. Plus, she has done so much to make my fantaszes come true that I think I owe her. We are swingers and we have a couple of friends in mind but we have yet to try anything. Can the guys here or bi ladies on this board help me out on how to suck it well?
