You and the lion start to rub your fronts together, your passion and lust increasing. You start to licknibble down your mate's neck, trying to push closer to him. You grab your paws around his back as you feel your limbs starting to expand, growing longer. Your mate grinds his hips against you as his legs and arms follow suit, both of your bones cricking and cracking as they reshape, your body's lengthening a bit as they grow morphic.
