When you wrap a woman's long and stretched out beef curtains around a man's penis with the head peaking out. If it's that time of the month, it comes with marinara.
"Hey honey. Are you up for a pig in a blanket? How about with a side of marinara?"
I almost got busted trying to sell drugs to an undercover cop. I knew he had to be a pig in a blanket when he asked to buy some "marijuauna cigarettes". Then I noticed the doughnut crumbs on his shirt, so I didn't even bother with him.
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.
Cheryl has such a nice, plumb ass that I couldn't help but treat myself to a pig in a blanket after dropping a load on her crack.
