As I walked into her room the first thing to hit me was the strong scent of the lavender, it was nothing too powerful but as I let wash over me I felt calm and relaxed. I looked about the room noticing some dark purple candles, the source of the lavender scent, standing against the walls on black metal platforms. My eyes moved over to the wall on my right, where there was a large bookcase that was home to some very old looking books and scrolls along with a large fireplace that looked as if it had been used recently. To my left was a dresser with a large sliver framed mirror atop it, next to the dresser was a door that I assumed lead to her private bathroom. Opposite of the door I had just entered, there was a glass door set between two large windows, leading out to a balcony facing west. Where one would have a perfect view of the sunset. In front of the balcony doors sat a large, impressive looking desk composed of a dark wood stain that made it look almost completely black. However, I did not have enough time to properly appreciate any of this due to the impatient mare pushing me further into the room.
I found myself on top of a large circular bed in the middle of the room with a collection of sliver pillows scattered around it. When I landed on the bed Luna pounced onto me. I Vaguely noticed the black silk sheets being displaced around us as she kissed me. I quickly returned the kiss with an equal and heated passion. She then lifted herself away from our kiss, standing on all fours. I propped my self up on my right hand and put the other hand behind her head.
"Are you sure your ok with this?" she asked as I began to trail kisses up her neck stopping to give a playful bite every now and again. When I reached her ear I simply said that everything was fine with me as long as she was up for it. I smiled when her ear flicked after I had finished whispering to her. "O-ok" Was all she said before we returned to our heated embrace, only breaking for air when we had to.
She broke the kiss first and with a sultry look said, "I think you should take these off." Indicating my clothes by pulling on my shirt with her magic.
I grinned back, "You know you may be onto something there." and with a small show of strength I rolled over effectively flipping her on her back electing a small scream and giggle from my lovely companion.
I began to remove my clothing while still on top of her, but after only removing my shirt I noticed that she had already removed and put away all of her regalia. As I started to remove the rest of my clothing I saw her horn light up as she raised the moon into the sky. After the moon was raised and all of my clothing removed I pounced on top of my new lover causing her to fall into a giggle fit once again. I trailed kisses up her neck and we resumed our embrace kissing once again as I had my arms wrapped around her.
Just as things started to heat up a primal growl escaped my throat. She seemed to like it. However, it caused me to pause slightly. When an all to familiar burning chill ran down my spine I began to panic. When I looked out the window my fears were confirmed, because instead of the nights quarter moon was a full moon at its peak in the sky. Luna was quick to notice that something was bothering me, due to the sudden change in my demeanor.
"Hey. Is something wrong?" She asked, concerned about me.
I ignored her and did the only thing I could think of at that point. I leaped off of the bed and ran out the open glass door to the balcony. When I reached the railing I heard Luna call out to me. But when I turned around she gasped in shock as her eyes met my own, now glowing red from my worsening condition. I turned away in shame, hating having to hide who and what I was. It was a lesson taught to me from birth, to always lie and trust no one with your darkest secrets but your own family. But... I didn't have a family any more.
I looked over the railing and saw that it was a good sixty foot drop. A normal human would likely perish from such a fall, but would be no problem for me. With my mind made up, knowing that I had to get out of there before my full transformation I vaulted over the railing. The only thing I heard before landing was Luna call out my name again. I started running as fast as I could, heading for a nearby forest. Some place far away from where anyone could find me.
It took all of my conscious will to keep my self from changing. When I finally thought I found a nice secluded part of the forest I let everything go. It felt like fire was dancing across my skin as thick brown hair grew to cover me, every bone in my body was breaking so that they could reform into a more 'appropriate' shape. I felt my skin rip and tear as I grew larger and my muscles became thicker and re-positioned themselves. My skull cracked and changed shape as I began to grow a muzzle. My teeth began to take a sharper more predatory shape, the tips of my fingers felt like they were going to split open as large black claws grew from were my nails should have been.
I screamed in pain and agony throughout my transformation until there was no more air in my lungs. Afterwards I took a long deep breath, filling my lungs with air and causing them to expand even larger then they were before. I tilted my head up to the sky looking at the full moon and let out a bone chilling howl. The transformation was complete. The Beast Was In Equestria.
