I actually gained a bit of a thing for cyclists when I caught a few of the couriers around the city waiting at the lights, and loved how some of them had these really massive arses that were just so round and firm and so damn prominent in those skin tight black shorts. As an arse man I love that fact even though a nice bulge up front is always appreciated, but to me it seems a lot of cyclists have some really nice round, firm bums.
Actually noticed a lot of guys in my spin classes too have nice bums too after tending classes for a while.
