Back half

Without a word, Olivia begins lifting your legs into the felt horse skin. You start to argue but are interrupted as she pushes your head down into her chest. She holds you in that position, your face pressed against breast's as you hear the sound of a zipper closing while you feel the material wrap around your body. You're soon pushed down, sliding away from the fleshy pillows, as your upper body rests on a firm stretch of material. You feel the costume tighten even more around you, now pinning your arms to you your sides as it holds you in a bent over position.

"Perfect!" Olivia exclaims looking down at you. "Now let's just hope it fits both of us."

You watch Olivia turn around till your only view is her plump rounded ass. As she bends down to pull the suit up around her legs, your face is greated by her soft pillows cheeks. This doesn't stop however, even after you hear another zipper and feel Olivia stand up completely, your face is still firmly planted against her ass.

"Mhmmhmmhmnmh!" Is all you can say as you try to speak as her soft, squishy behind muffles your sounds.

"Oh good! It fits!" You hear her exclaim.

You're surprised she's not more bothered by the feeling of your face practically spreading her ass cheeks apart. You're able to move your head just enough to find a pocket of air that allows you to breath the best as Olivia makes a few small movements that you assume is her adjusting the costume.

"Ooh! This looks so good!" She shouts excitedly. "Too bad you can't see it, I look amazing."

It's now you start to wonder exactly how long she's expecting you to stay in this position, as you don't know if you'll be able to remain like this throughout the night.

"Well! Time to party!" Oliva exclaims.
