When you are having sex with Mexican girl and while you are fucking her you put your finger in her asshole and start fingering her and still keep fucking her.
While I was fucking the Mexican girl I Bean Burrito her
A refried bean burrito, much like the normal bean burrito, is where the man gives anal sex to his partner, and then receives oral sex from a different partner.
Man, i gave Clara anal and then gave Sarah a refried bean burrito!
