The recipient of this sex act hangs there head out of a second story window. The male comes from behind penetrating whatever hole the receiver chooses. The male continues until he climaxes on the window and asks the recipient how is the weather. The recipient must claim that its nice outside and looks like a good day to clean the windows.
