Spankloshing
Noun: the combination of two sexual/sensual practices spanking and sploshing. First, thorough spanking is administered to the spankee. Then, when the booty is red, hot, and stingy, the spankee immediately sits on a cold cake (pavlova is preferred). This is followed by more general sploshing by all participants.
Spankloshing was developed as an extension of the base practices of spanking and sploshing.
