if I got this right:

The bunny was doing doggy to the kitty in her pussy.

Wasn't getting much of a reaction from the kitty, so he hops around for some FBBBJ (Fur-Back Bunny BlowJob).

Now, I do say this video should be watched with caution since I didn't see any protection being used.

About 20 years ago I took my son and his niece and nephew to the Reston petting zoo. While they were on the riding the two giant tortoises, the male got a boner and tried to mount the female. We had to get the kids off quick before they got squished.
