With an Xtube username like Btm4Azns, the bottom in this video seems like a man with of very specific sexual appetites. Normally we'd chastise a guy like this for not being more adventurous, but it's hard to argue with results!
Who knows? Maybe this guy has hit the motherlode of hot Asian tops, and they all fuck as well as the guy in this video does. Either way, people like what they like, and there's usually no point in trying to talk them out of it. We've definitely wasted way too much of our time trying to convince guys who only fuck White/Asian/Latino/top/bottom/tall/short/whatever dudes to expand their horizons.
