You decided to go to the door with the lion on it. Walking over to the door you slowly push it open and step inside with a gasp.
Out in front of you is a large expense of plains with a large rock formation in the center of the room... or was it room. Slowly stepping further into the room and away from the door it suddenly shuts behind you, quickly snapping around you watch in shock as the door dissolves into thin air, leaving you standing in the middle of these plains alone and with nothing but grass and the rock formation around you.
Gulping you decide to head towards the rocks. Slowly moving through the grass you fail to notice the eyes peering at you from the grass, the large lion watching your every move as you get closer and closer to the rock formation that seemed to be more like a cave.
Just as you reach the rock formation the grass seemed to thin around it to the point where it was barely taller than your shoes. Stopping you look up in awe at the rock formation as behind you something starts to growl. Whipping around you barely had enough time to gasp as the large lion leapt at you, knocking you down to the grass as it held you down with it's paws.
You stared right into the lion's eyes with fear as the lion seemed to tilt it's head at you before looking down at your body before looking back at you and sniffing. You try not to show fear as the lion sniffs your face before stopping... and giving you a lick. You blink in shock as the lion slowly get's off you, you put your hand to the wet spot on your face before taking it away, a heat starting to build up in your chest as the lion lay down and watch you.
You didn't want to move for fear the lion would pounce on you, but it seemed just content to watch as the heat in your chest continued to build. Your clothes were starting to get uncomfortable on you as you fiddled with the neck of your shirt. But soon it was to much and you started to take your shirt off. Quickly throwing it to the ground you fiddled with your pants and underwear before throwing those off to, fully exposing yourself in front of the lion as she sighed in relief from the loss of your clothing before something caught you eye.
Looking down you gasped in shock as your shoes, sock, shirt, underwear and pants all dissolved into nothing, leaving you without anything as you turned back to the lion who was still content to just watch as the heat in your chest continued to grow.
Suddenly the heat shot down into your genitals, leaving you blushing completely red as your dick went completely erect, the lion looking at it bored as you tried to turn around, suddenly feeling very exposed in front of this lion and embarrassed for some reason. You didn't know why but the heat in your chest was still growing as you suddenly cummed all over the grass on the ground and almost moaned in pleasure.
But that one piss had seemingly emptied you dick as you gasped, looking right down at your genitals as a tug started to pull them inwards. Blushing madly you could only watch as your balls were pulled back into your body and your penis continued to shrink, the lion yawning behind you as you turned around to face him automatically. This time the lion was focused on your genitals as it watched them shrink away into nothing, leaving your crotch blank for a moment before there was a small ripping sound and you blushed even more.
Your new vagina opened up in full view of the lion as he licked his lips, slowly getting up and walking towards you as you stood still, not wanting the lion to rip you to shreds as it sniffed at your vagina, the heat in your chest continuing to grow as the lion suddenly licked your vagina.
That instantly sent you over the edge, orgasming from the lion's tongue as you fell over backwards, lacking back first in the grass as the lion climbed on top of you again, holding your arms down with his paws as he licked your face. Blushing again you felt your chest bubbling, and looking down you watched in shock as four more nipples formed down your chest before breast tissue formed under them, making small c-cup mounds on your chest as the lion looked pleased with this development and put his mouth near your ear before giving it a small nip and drawing blood. "Ow!" You let out a cry in pain as the lion looked you right in the eyes before he opened his mouth. "Just wait... it will be over soon." The lion said in a regal voice that commanded respect as it got off you. You lay there in shock as the lion stepped away from you before laying down again. "You talked!" You exclaimed as the lion shook his head. "No mate, you understood." He said as you caught that word. "M-mate!?" You asked in confusion as the lion nodded.
"Yes. You are to be my mate. I have met every lioness in this plain but none suit my needs. I want one more... human." The lion said as he licked his lips. "Human?" You asked, the heat still building up in your chest as the lion continued to speak. "Your ears shall become like those of any lioness, and you shall lose those human hands and feet. You'll grow a tail and a short coat as well as join me on all fours, but otherwise you shall remain the same." The lion said as you felt the heat in your chest grow even more at that thought. "Why... why does that excite me?" You asked as the lion spoke once more. "Because you are destined to be my mate. You have no name anymore lioness, and now you are mine. Now then, please, take your position." The lion said in a commanding yet calm tone. His words soothed you however as everything unimportant started to flow away. Bending down and getting on your hands and knees you lifted your butt in the air as you felt your vagina start to shift again, moving into the correct position for a lioness as the Lion stood up and walked over to you.
"And so it begins." He said as he rammed his dick into your vagina, for a moment pleasure flood your system as you mewed, the lion roaring as he wasted no time filling you with seed before pulling out and leaving you gasping for air with cum coming out of your vagina as you rolled over onto your back and faced him. "Still to male for my tastes, but no matter. that will change as well." The lion said as you wondered want that meant for a moment before you started cringing, your bones starting to crunch and compress as your body started to slim into a female figure and your hair grew longer before turning brown, the change was nearly instant, but now you were a female with lioness genitals with six breasts. But it wasn't quick to last as your hips popped again, your legs shortening as you watched you legs move towards the sides, making your stance quadrupedal as your arms popped as well, forcing you to roll over and stretch like a cat as your arms popped into a quadrupedal stance before thickening a little bit and losing a bit of dexterity, making them a second pair of feminine legs with hands at the end.
This felt more natural to you now, being on all fours as you stretched once more, your spine popping just a little bit more as you gain a few inches in length and removed the ability to stand up straight for good. Turning around to face the lion you gave him a soft smile with your new rounded and cute face, the lion nodding at you as you walked over to him and lay next to him. "I love this." You purred, nuzzling to his mane with your head as he whispered in your ear. "It gets much better." He said as your hands and feet started to morph.
slowly but surely they became petit lioness paws, a light coat of fur on them that was growing up your legs to cover your body as your spine popped again and started to extend. Near your butt a small nub pulled out and extended, growing into a long lion's tail that lazily flicked behind you as fur continued to cover you fully. "All that's left is your face now mate." The lion said as he licked your face, you giving him a nuzzle and a lick of your own as your ears extend and moved, becoming a pair of lion ears as your tongue grew longer, and your nose became a smaller version of the lion's as fur covered your face, your hair extending and falling past your shoulders as you mewed, nuzzling up to your mate as he nuzzled you back. "Now I am complete mate." You said as the lion nodded. "And you already have our children within you mate... now let us rest." The lion said as he got up and led you up into the rock formation and the cave inside, letting you lay down on the rocks like the regal half lioness you were before he lay next to you and you both drifted off to sleep.
