Performed in the Doggy-style position. Occurs when a
guy grinds his penis in a girl's buttcrack while squeezing her cheeks together so they completely cover his penis. Requires a nice, soft
ass and lubrication, usually provided by the guy spitting on her butthole, or cumming on it after doggy-style sex, or after cumming inside her
asshole and having her squeez it out while he grinds.
