is the process of a male inserting both his erect penis and both testicles into the arse of a participating female of any species. When the bloke is about to cum, the Shally Whacking commences: the bloke rips his penis and balls out of her arse, and slaps her arse cheeks with his penis whilst cumming everywhere.
