Duos have always been a mystery to me.
Most of the time, the duo just sits there, maybe taking the time from their busy day to type something out.
My opinion is that duos are NOT designed for any chemistry between the two.
They seem to be designed to just maximize income which is fine, as long as the customers realize that.
Remember that many models are not gay and "bisexual" in name only. When they are with another guy, the may not be able to perform with an erection at all.
Don't confuse Flirt models with porn models; thee two groups can overlap but they are not the same.
