Happy with your choice, the female is getting very excited while a question enters your head.

"How do I get in?"

The Female looks at you oddly. "Why, obvoiusly, you can go up my ass or my vagina. Duh!" she adds with a giggle.

You are stunned by that.

"Oh, and you must be naked. It makes the entry sooo much easier..."

With the male rhino blocking any escape, you obey.

"Now young human, make your choice." she says, wiggling her ass and exposing her sex hole.
