Your heart sinks in despair as the rope binding your wrists slips over the splinter thus sealing your fate. The mare's rear gives another powerful heave and your arms are pulled inside pinning them to your sides.

You struggle desperately but all you can do is prolong the inevitable. The wiggling seems to excite the mare as it mare whinnies again as another spasm of its ass sucks you in up to your neck.

Emily giggles at the sight of your head sticking out of the mare's butt. She walks over and places a hand on your head and says, "Don't worry, once I find more people you'll have lots of company in there."

"No don't!" You shout. Ignoring your pleas Emily pushes on your head and you slide the rest of the way into the mare's ass.

You're surrounded in darkness with tight and wet walls pressing on all sides of you. The worst thing of all is the smell... Oh god the smell!
