I take off my pants and panties, put on my spin shoes and stick my medium Tyson the Water Buffalo dildo to the bike seat. Unfortunately the seat is cushioned so the suction cup doesn't stick great, but it serves its purpose for a little while. The only lube I get is my spit before I ride it up and down while on the bike. (1920 x 1080, dslr camera, 3:11, .mp4, h264 )
