Imagine a devious pred convince prey that he knows the best hiding spot for hide and seek.
Like quiping, "who would ever think about a pred like me hiding someone in me for a hiding spot"
Could have multiple prey all that fall for his charm. One down the gullet, one in the balls and the last one going right into the ass.
The seeker of the games begins looking around the one hiding, and run across the park. The pred has one more hole to fill for they are herm, and they want the prey in them.
So they offer to help find their friends and suggest that maybe they found a really private spot. After much coaxing they convince the seeker to check inside the (insert species) vagina.
