Exhibitionism……Cas wearing a skirt onto the train and sitting down in Dean Smith’s lap, subtly undoing his slacks when they hit a bump, and sinking down onto Dean’s cock, the cutout in the back of his panties perfect for easy entrance. He keeps Dean’s cock warm during the whole train ride, and no one notices. When the carriage rocks, Cas gasps in pleasure, unable to contain the noise as Dean’s cock brushes deep inside him. His own cock is trapped by a cage, so he doesn’t have to worry about getting hard, but that too is agony, denied release while Dean subtly rocks his hips up and in, fucking Castiel as slowly and shallowly as he possibly can. When they near their stop, Cas raises up just enough to let Dean tuck his cock away and zip up his pants, then settles right back down on his lap, smiling innocently at the other people in their compartment.
