I love getting my back blown out like this by an unknown top or two (or three)! The lucky bottom here should know his place, though. He should be focused on the pleasures he's giving to his top(s), and getting his pleasures from that. A bottom, especially a white one, is there for the top(s), his/their pleasure and needs. All other pleasure a good bottom gets is incidental, and at the discretion of his current top(s), usually involving repeated internal prostate stimulus.
