C'est une femme entièrement naturelle

Toby is kind of an eager beaver himself as he goes around collecting signatures to Save Endangered wildlife such as the Southern Beaver. Tatiana drags him inside under the guise of learning more but rapidly hunts and captures her prey. The innocent appearing Toby. With amazing dexterity, Tatiana removes his hides and goes about the preservation process, starting with spit cleaning the softer bits of his anatomy. Once thoroughly cleaned, she mounts him, and on the way gets a little stuffing of her own. The pelts of these two as natural critters mesh and intertwine and along the way Toby mounts her like the monster he is. A mid-stuffing spit clean and they're back to pounding flesh until Tatiana manages to squeeze out every last drop of bodily fluid she can, all over her face. A quick clean up in the shower for her and it's pretty clear that at least HER beaver has been saved from fate if none of the others.
