The roomy cavity slowly contracts around with all the air leaving by your feet. You are held firmly in its grasp for a few moments when a series of powerful waves of sweep along the rectum of the female rhino.

With each contraction, you are held so tightly you can't draw a breath. Her orgasm builds in intensity, and each successive one pulls you further inside her. With a slippery noise, your legs join you inside her, and now you can feel the change in texture of the rectum as you near her inner sphincter. The inside is very wet now, with a smell you find arousing but unfamiliar.

You can breath well enough in the moist air, and you can still sense the males penis as it thrusts in and out, though only by you lower legs now. There is more space now, enough to move your arms and legs a bit.

This is more than you bargained for, and you come to the conclusion that the two of them have forgotten about you in the passion of their mating!

You feel around by your head and there beneath your fingers, is her inner sphincter. You slide a hand inside to your wrist then to your armpit. Within, your arm swims in an airless volume of waste. The female rhino responds to your arm by having another orgasm, her most powerful one yet. The contraction is so strong this time, it almost pulls your arm off. You realize that if your head had been inside, it might have broken your neck.

The male announces "You've been helping her long enough. Its time you experienced my ENTIRE penis." Your sore anus from his last time throbs with painful pleasure to remind you of what that felt like, and you can barely imagine what the entire length will be like.

You decide you can let the female expell you alive to be further sodomized by the male or you can push your head inside and hopefully, you'll die before she realizes whats going on.
