During anal intercourse, the male will remove his penis and reinsert it in the girl's vagina. The feces on his penis are transferred to the girls vagina creating a dirty muffin.
Last night, I was giving it to her in the ass, then before I blew my load I stuck it in her puss. By the time I was done she had one dirty muffin.
