The act of slapping or spanking a female on the buttocks during sexual intercourse in an overly exaggerated manner. A technique often used in so-called reality porn sites such as MILF Hunter. Usually performed during anal or vaginal penetration from behind such as in the doggy style or doggy position. Initiated by several full arm rotations and completed with a hard buttock slap.
While pounding her ass he gave her the spin hand a few times.
