I used to have a "signature move" too, which you may find odd. It used to drive some guys crazy, while others just found it amusing but weird. With certain guys, usually regulars, I would get up close to their ears, as if I was going to whisper something into them. Then I'd just open my mouth wide, and just breathe into their ear, lightly just normal breathing. The hot breath would turn some guys into putty, as if they were about to melt. The ears are an erogenous zone. Some people are too sensitive to be touched on their ears and hate it, while others can have orgasms just from the ears. But I found that both types of people found this pleasurable. Since no actual touching is going on, the people who hate being touched on their ears have nothing to complain about, it's just hot air blowing over their ears.
