After a bountiful feast of Mexican food dishes, you take your female counterpart home for sexual activity. While you are in the process of having anal sexual relations with her and you reach your point of climax, you promptly stick your finger down your throat to make yourself vomit all over her back as you simultaneously ejaculate in her rectum. After you finish disposing of fluids inside of her, you proceed to take your half flacid package and rub it up and down on her back in your own vomit, so as to mimic an actual mudslide.
Holy shit! Ian just did the Mesa Verde Mudslide all over Katie!
