Your arms and fingers are the next you feel changing. But you can hardly feel the pain as the pleasure from the two shafts rubbing is nearly overwhelming. You realize that you are changing into a loin completely. The pleasure and transformation go oin until finally both you and the lion on top of you climax. Your seeds mix and you feel the last vestages of your human body fade away. Your mind is changing as well. You are a full male lion, and you are a mate to this other full male lion. Nothing else matters to you.
The lion releases you from under him. You have a chance to leave, but instead he and you begin cleaning yourselves. He nuzzles you, rough tounge against your facial fur. You return the gesture, and find yourself wanting to please your new mate more. He seems to have the same thoughts.
The two of you lick eack others body's clean, then snuggle up against each other and sleep.
When you wake you find a large antelope dead in front of you. Your mate has already eaten, so you eat what's left. After breakfast, you and the lion nuzzle again. You lick him, and find your cock begining to expand. You can see that his is too. You sense that something is going to happen soon...
