The Transformation
With that, Lilith took the contract from me, pricked her own finger, and signed it, saying, "It is done." Then as fast as it had appeared, it disappeared from her hand, and at the same time, I felt something form around my neck. I reached up and felt that there was now a collar looped around it. The collar was loose enough to feel choked but tight enough that I could not get it off. There also was not any kind of clasp. Instead, it was one solid piece. At the front, next to a sturdy-looking ring, was a dog tag that just read "LT."
I couldn't believe it. It was happening! I was now the pet, maybe even the sex slave, of a mighty demigod for lack of a better word, and yet I wasn't scared. I knew without a shadow of a doubt that she would keep to the contract and that I had nothing to fear.
"Please follow me; it is time to get you ready," she said as she started out of the room. "There are a couple of ground rules we should go over: one, and you do what I say. Two, you do not enter any of the rooms on the second floor unless I tell you to. #3, you will address me as your mistress, and with respect, I deserve as such. #4 You will not wear any clothes unless I tell you to, and I arrange the outfit. I will be making new rules for you as we go, but I want you to experience some right away. Do you understand these rules?"
"I do, mistress."
"Good, in here," she said as she directed me into what looked like a bathroom. There were a few odd things about it, though. The most bizarre thing I observed was a strange-looking machine right next to the toilet. It looked kind of like a vacuum hose with some sort of locking mechanism.
"What's that?"
"Aww, that is something I will show you how to use tomorrow. For now, I want you to strip, and then it will be time for you to drink your potion," she said as she walked over to a locked case in the corner filled with large vials of green liquid. I slowly began to strip as she retrieved a vial. When she turned back to me, I was only half undressed. "Hurry up, the faster we finish this, the faster we get to get to the fun stuff. And don't worry about your appearance. I've seen you naked plenty of times, and you won't be wearing many of your clothes after this anyway. Be proud of your body, and if you have any problems with it, we can work on it while you're here. Now show me what you got!"
Feeling much more emboldened, I quickly stripped off the rest of my clothes, my half-hard cock standing in front of me.
"You see, you have nothing to be ashamed of. I like your body. The only change I'd make to it is your cock size, and that has nothing to do with you. I'm just a size queen, just as you are a size king. Oh, and I want to make anal for you so much easier. Drink this," she said as she handed me the vial. I took it and uncorked it, getting a whiff of fresh strawberries as the stopper came out.
"Bottoms up." and with that, I drank the entire vial. It was sweet and tangy.
"Now, the effects will be rather fast, so I would advise going to the toilet right now." As I immediately headed to the toilet, I could feel the effects of the potion as it worked its way through my system. It wasn't painful, just a little uncomfortable, and then the shitting started. It felt like my bowels were excised of all contents, which was probably what was happening. It only lasted about three minutes before it slowed to a stop. That is when I felt it. It felt like all the times I had used lube to play with my various toys. My bowels felt loose and slick. Again it wasn't painful or uncomfortable--just different. This was going to take a little time to get used to. The other thing I quickly noticed was the change with my cock. It was now over a foot long and over two inches in diameter when hard, which it was now.
"The potion should have finished its work," Lilith purred. "Come out here and show me the results." Holding my head high, with nothing but the collar around my neck, I walked out of the toilet. "You look perfect. Oh, and look at this beauty!" she said as she came over and stroked my hardened cock. "It's just perfect. It's not as large as mine but just the size I like. I can't wait to give it a test right very soon. But first, let's see how the other parts worked." With that, she reached around me, and with no pressure or pain at all, she slipped three fingers inside me to their base. "Perfect; how does that feel?" She asked as she began sawing the fingers in and out of my hole.
"Good, mistress."
"But my little fingers aren't big enough for you, are they?" She asked while adding a fourth finger.
"No, mistress," I groaned. I loved anal and played with myself many times, but it never felt this good, nor did I ever feel this empty before.
