As a girl is face down ass up, you approach her from her top side, going back to the ass where you enter her vagina in a "jackhammer" fashion. While you proceed to jackhammer her, you shit down her back. A more liquid poo would be optimal, but any poo will suffice.
Kelcie's favorite thing to do is the Cancun Mudslide, she says the shit running down her spine is orgasmic.

Jaymin will always remember that Kelcie said yes to a Cancun Mudslide in Cancun.
