Becoming One With Twilight

It had been three months since I took part in a program that allowed ten humans to move to Equestria and allowed ten ponies to relocate to my world, maintaining our natural forms. When I first came to Equestria, I was fully expecting it to be inhabited by the ponies from the show that I love so much. While those same ponies were there, they were anthro in form. Everypony wore clothes and they had human anatomy which wound up being a good thing and a bad thing.

The bad thing was that one particular mare, one that I had quickly fallen in love with, had large breasts and curves that would drive any man wild. Yes I did fall in love with Starlight Glimmer rather quickly and after just one date, we had become a couple. Soon we were spending a lot of time together and she was the one that gave me my first kiss in Equestria. Most of her friends were happy for me. Key word though, most. Eventually I learned that one of her friends was very unhappy and believed that I had seduced her friend.

It was Princess Twilight who was not thrilled with me being Starlight's special somepony as they put it here. I would be nervous when I got a letter in the mail from her ordering that I go to her castle on a Saturday morning. I wasn't sure what it was that she wanted but I did have my concerns that being an item with Starlight might cause me to wind up in Tartarus, on the moon or perhaps simply being sent back to my world. I had grown to love Equestria and especially Starlight so being forced to return home, knowing that I would be without my love, would be pure torture.

When that Saturday finally arrived I headed to Twilight's castle to find a note on the door. It read, "Luke, nopony but me is home. Come to my chambers so we may talk over your unnatural relationship with my friend."

My initial thought was, "How am I supposed to find her chambers? I have never even been in that place!"

I opened the door and apparently Twilight must have wanted me to find her easily because there were arrows that pointed me in the right direction. The closer to her chambers I got, the more nervous I got. When I finally got to the entrance, I could tell it was her chambers because of her cutie mark being on the door. The door was cracked slightly but I wasn't about to just go barging in.

I went to knock on the door when I heard a voice say, "Come in Luke, we need to talk."

I pushed the door open and the room was filled with a green mist. This was both concerning and confusing. My initial thought was that perhaps that it wasn't even Twilight who wrote me and that whoever was in here was one who possessed dark magic. I then thought that maybe Twilight had a dark side to her that nopony else knew about and that she was using this to scare me.

As I headed further into the room, I saw a figure standing there. It was clearly a female and she motioned for me to come closer. I did as ordered and once I got close enough I discovered that it was indeed Twilight. She was wearing a very revealing black outfit along with a seductive smile. I also noticed that her wings were more batlike in appearance than what a normal Alicorn's wings are like.

She again motioned for me to come closer, "Luke, as you probably know, I am not pleased that you are in a relationship with one of my friends, especially one who I feel is so vulnerable to being taken advantage of."

I was very nervous over her comment. I gulped, "I'm sorry Princess, things just sort of developed between us. The chemistry is there and so is the love."

She spread her wings wider and more green mist filled the room when I said that. I knew that she was not one bit pleased as she ordered, "Undress now so that we can further discuss this."

I really did not want anypony seeing my nude body at that point but all of a sudden Twilight gas giving me the most seductive smile and batting her eyes at me. All of a sudden I found her irresistible so I began to undress for her and she did the same for me. Once we were undressed, she again motioned for me to come closer. She approached me as well and quickly we met.

The looks she was giving me were full of lust, of desire. While I did love Starlight, Twilight was irresistible and I couldn't help but embrace her, an embrace that was quickly returned. We gazed into one another's eyes and soon her mouth opened wide, with her tongue hanging out. I too opened my mouth and stuck my tongue out for when our kiss would begin.

She pulled us into a kiss and our tongues would begin a love dance. Very quickly I could feel her saliva flowing into my mouth, saliva that I greedily swallowed. The longer we kissed, the more my desire for her became. After what had to be at least an hour, she broke the kiss and pointed towards a bed. She then begged, "Take me Luke, take me. Fuck me, make me feel like a queen!"

One part of this seemed so wrong but another part of it seemed so right. I had always found Twilight attractive and now here I was, in her chambers just moments away from having sex with my favorite princess. I knew that the green mist was likely a bad sign but I couldn't help it, my desire to give her the sex she desired was far too great for me to even think of running away because of the green mist.

She laid down on the bed and spread her legs wide. She was giving me such an inviting smile, a smile that I couldn't say no to. I also saw her pussy, it looked so inviting and it seemed like it was gazing straight into my soul. I got into the bed and readied myself to give her what she so greatly desired. As I lowered my member to her opening she begged, "Please Luke please, please fuck me!" She then said something in a much quieter voice, something that I couldn't make out all that well. It sounded like she said something along the lines of "Become mine" but I couldn't be completely sure.

As I inserted me member into her, I wrapped myself around her and we engaged in a passionate kiss. I pushed myself all the way into her and soon I hit a barrier that gave way rather quickly. She let out a loud scream and sank her sharp fingernails into my back, causing me to let out a grunt of pain as well.

I was about to pull out because I was concerned I had hurt her but then she let out a hiss, "Fuck me Luke, fuck me! Become mine, become my property!"

At that moment I was scared and realized that perhaps doing this with Twilight was a mistake, especially with the green mist but it was too late at this point. I was in her already and even if I were given the chance, I wouldn't stop here. Her walls felt so good around my member and I had begun to feel a bond with her.

Once I began to thrust her, I could feel her walls tightening around me and it felt so good. She was so hot, wet and tight and that was like a slice of heaven. Not long after her hiss, we began to kiss passionately again and I could feel her magic flowing into me. As I continued to thrust in her, I felt something changing about myself. I felt myself begin to grow a bit, I felt a horn sprouting from my forehead and I felt wings growing out of my back. At that moment I realized that she was using her magic to transform me into one of her kind.

The longer our intimate encounter continued on, the more and more my desire for her grew. Eventually I had completely forgot about Starlight as Twilight was the one who had all my love and adoration. When the time finally came and the two of us climaxed together, I felt something truly special as I unloaded into her. I felt as though we had become one. After I had released into her, I continued to thrust while I could, I wanted her to have every last drop of what I provided her.

Once I pulled out, she turned us onto our sides and gazed deeply into my eyes. She asked, "Luke, who do you serve?"

"I serve you Princess Twilight."

"Who do you love?"

"I love you and you alone Twilight."

"Whose property are you?"

"I am your property Twilight, yours and yours alone."

She gave me a purr and pulled me into another deep, passionate kiss. As we kissed, I continued to feel her magic flowing into me, lovely wonderful magic. In just that moment, Twilight had captured my heart and she was the only one I wanted to be with. After a long passionate kiss, she got up and pulled me up. She led me to a mirror and ordered, "Look at us Luke, we truly are one now."

I looked in the mirror and she did use her magic to transform me into a pony. I was a white Alicorn with a short blue mane and tail. What surprised me most though was my cutie mark, it was an odd one. Now I worked in a bank so the bag of money part was no surprise but I also had hers and both of them were inside a red heart. I looked at her and she had the exact same one. Her statement that we had become one was true.

We gazed at our reflections and suddenly the bat like wings were gone, we appeared as though we were normal ponies. I wasn't sure what the green mist and the bat wings I saw earlier were all about but what mattered now was that we were together. She grabbed me by the hand and suggested, "Shall we go for another round Luke?"

I replied, "I would love to Twilight."

We headed over to what was likely our bed now and started another round. I wasn't completely sure what the future had in store but I did know one thing, I was Twilight's property, we loved one another and that we would be together for all eternity. For quite some time my love was for Starlight but now, my heart belongs to Twilight and Twilight alone.
