Posing trunk teasing (& skimpy briefs)

My fetish is posing trunks. And the underwear that looks (more or less) the same: bikini briefs. I wear those 90% of the time and it totally turns me on, when the other guy wears the same. A super turn on for me is when you just the small skimpy side of the posing trunk or bikini brief above the guys shorts or pants.
