A male or female with a colostomy bag that will remove it so you can pound one out in the stoma.
I scored double with that filthy prostitute. She blew me for $10. Then found out she’s a side slider so she let me pound it out in her for another $10.
When you lay out a tarp, cover it in baby oil and/or lube, and have her lay at the other end with her legs spread out. You then make the East-Side gang sign with your hand and slide along the tarp until you insert your first two fingers in her pussy, and then your pinky into her asshole.
Yesterday we tried the East-Side Slip n' Slide but I missed and ended up with road burn on my pecker.
