Lilith's House

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.

"You need something big and hard deep in this hole to feel complete, don't you?" she asked as she gently pushed me forward and, to my amazement, easily eased her entire fist inside my ass. I had never fisted before, and it felt amazing. After that, all I could do was groan, and she slowly began stroking her fist back and forth, never taking it out. "I asked you a question."

"Yes, Mistress."

"Yes, what?"

"Yes, I need something big and hard deep in my ass."

"Bigger and longer than my measly fist?" She now nearly elbowed deep in my ass. I had never had anything so deep inside me, but I knew she was right.

"Yes, mistress, something bigger and longer than your hand."

"Good, then follow me; it is time for your training to begin," she stated as she quickly pulled her fist from my ass. "The pleasure is just beginning."

I could feel my asshole gaping mildly as I followed her out of the bathroom and down the hall. I had always gotten this feeling of emptiness when I knew I needed to get filled and play with my toys. Right now, I had that feeling, but it felt like it was ten times more intense. We passed a door that had a placard on it labeled "JOHN" in blood-red letters. "That will be your room when you have time to use it. I'll show you all its features probably tomorrow. For tonight, you sleep with me." We continued down the hallway until we reached a sizeable double stairway. When we came to the top, there was a set of large double doors. Once at the top of the stairs, I noticed a hallway running east with many doors on each side. These must be the forbidden doors she spoke of. She opened the large double doors with a flick of her wrist, presenting me with a large bedroom with a four-post king-size bed situated against the back wall. There was a fireplace in one corner and a plush rug covering the floor. "Please lay on the bed on your back, and we will get this party started," she instructed me. I did as I was told and was greeted with the most comfortable bed I had ever been in. Not only that, but the sheets felt like I had always dreamt that sleeping on a cloud would feel like. It was magnificent. "Comfy bed, hun?" she smirked as she walked over to me.

"Yes, mistress, the most comfortable I've ever been on."

"Good, I'm glad you like it. There will be a queen-size version in your room, but let's not worry about that right now. Give me your hand." With that, she secured me to the bed with incredibly comfortable and yet strong restraints. She placed one of the fantastic pillows under my head to have a perfect view of the room. "Now, you wait here while I get myself ready for our evening and get you your first present." She left through one of the many side doors, shutting it behind her. As I laid there, fully naked on the comfy bed with the growing empty feeling in my ass, I started looking around the room. The first thing I noticed was the restraints around my ankles. They seemed attached to skillfully hidden pulleys allowing her to reorientate my legs to suit her needs. Casting my gaze around the rest of the room, I noticed a couple of old-looking chests of drawers and some more nice-looking art, including another portrait of Lilith above the fireplace. Overall the room had a very well lived-in vibe. I continued my study, knowing that if I didn't, there was a very high probability I would just fall asleep in this bed, and I did not want to do that on our first night.

I did not have to wait long, as Lilith emerged from the room only about five mins after she had left. However, her look had changed entirely. She was now dressed in a complete dom outfit: she wore a red and black leather corset that cupped the bottom of her large breasts, leaving her nipples exposed, long black gloves that went back to her elbows, a garter belt just below her corset that was attached to knee-high lace stockings, and a pair of black high heeled boots which completed her ensemble. She had also put on some makeup. One thing missing was any hint of panties, giving me a full view of her beautiful full nether lips. Her nipples were hard as rocks and fit her breasts perfectly. I had to keep reminding myself that she wasn't human and that she had altered her appearance for me. However, that didn't change the fact that she was beautiful. She stood there posing for a bit of a bit, allowing my eyes to traverse her body. "You like what you see?"

"Yes, mistress, you're magnificent. But, it doesn't do you justice. I honestly lack the words to describe how amazingly incredible you look."

"Why, thank you, my pet, but if you continue like that, I'm going to get a big head. Then again, if you like my front, then you're just going to love this." With that, she twirled around and went over to the nearest dresser, though not before giving me a nice long view of her perfect ass. Nice and firm with just the right amount of pop. She even made a show out of bending down into a drawer. My eyes snapped to what she had gotten out. It was a massive 18-inch long dildo that had to be close to three inches around. "Let's get you ready for the main show. I bet your ass is just begging to be filled."

"Yes, mistress"

"I want you to ask me for it and be specific."

"Mistress, please stick the massive dildo in my ass. I can't take much more of this empty feeling," I begged. Lilith strutted over to the bed where the pulleys were and reoriented my legs so that she had easy access to my aching hole. She then began teasing me, gently pressing the head of the massive dildo to me but pulling back before it could enter me. I knew it was huge, but I also knew I would have no trouble taking it with the modifications from the potion. Finally, I could not take any more teasing, so I begged, "Please, mistress, I can't take any more teasing, please give it to me!" With a smile and a wink, Lilith shoved the dildo inside my ass, plunging it halfway in one go. God, did it feel unique? Whatever that potion had done, it had done it well. There was no pain, just a fantastic feeling of fullness, and I definitely could tell my ass was much more sensitive. I could feel every bump and ridge of the toy as she began to saw it in and out slowly. With each thrust, she pushed it deeper into my depths until a slight bulge could be seen in my stomach, where the dildo was inside me.

"Just think about later tonight when it will be my cock in this hole and not this fake dildo. It is twice as long as this and a little thicker. You are just going to love it," she purred as she continued thrusting at maximum depth. I had never felt anything like this before. Never had I been able to take something so big or so deep and to think her cock was going to be bigger and much longer--I knew I wasn't going to last much longer.

"Mistress, I'm going to cum," I said with a bit of desperation in my voice.

"Oh no, you won't. You aren't allowed to cum until I permit you," she stated with authority in her voice. Immediately, I knew that I would not be able to cum until she said so, but the feeling wasn't going away. Luckily, she had mercy upon me as she pressed the dildo all the way to the fake balls before reaching into her bedside bureau and pulled out what looked to be a roll of tape. As I looked at her in confusion, she began pulling off a two-foot-long strip, saying, "This is an exceptional kind of tape. It will hold the toy in place while we do other fun things until I'm ready to fuck you while being body-safe. It is powerful, and yet when pulled off, it doesn't take any hair with it, so it is not painful." With that, she placed two pieces criss-cross around the back end of the dildo, pressing it in as far as it could go. "Go ahead and try and push it out." I did as I was asked, pressing down, trying to push the large intruder from my bowels, but it wasn't moving. "That's enough; I wouldn't want you to hurt yourself. Oh, by the way, this toy is more than just your good old-fashioned dildo." All of a sudden, I felt the dildo come to life. It began vibrating and undulating in different directions. "Fun, isn't it?"

"Yes, mistress."

"But enough caring for you. I think it is time for you to put that tongue to some better use than talking."

She climbed up on the bed and began to straddle my head. "If you please me enough, I promise to reward you," she said as she lowered her dripping pussy down to my waiting mouth. I caught a drop of her nectar as she fell herself, and it tasted like a fresh ripe peach. It was incredible. After what felt like an eon, (though in reality, it was only a couple of seconds), she settled herself upon me. She was considerate and made sure that I could still breathe while giving me complete access to her nether lips. Without another second of hesitation, I delved in, first just exploring, getting to know her pussy and its incredible taste. Still, soon I got down to business trying to pleasure this beautiful goddess. I went back and forth between playing with her pronounced clit and delving my tongue as deep inside her as I could. I could tell by her moans that I was doing a good job. As her moans started getting quicker and loader, I increased my time on her clit. To my surprise, it only took about eight minutes to have her cumming all over my face. And when I say all over, I mean all over. What seemed like an endless flood of fluids came streaming out of her pussy as her body tensed, and she let out one hell of a wail. I drank as much of her tasty juice as I could, but there was simply too much, and soon my entire head was soaking in it.

"You did quite well, my pet. Most of my pets cannot make me cum so fast on our first time, and yet you have. So you have earned your reward."

She flipped around (so she was facing away from the wall) and re-lowered herself back to my lips. Then she did something incredible. She took my insanely hard cock down to the root into her mouth. What came next was by far the most fantastic blowjob of my life. She started by deepthroating my cock up and down before pulling it from her mouth and running her tongue up one side and down the other. Then she began to just play with my cock head in her mouth before getting into a rhythm of alternating between the three though in no discernible pattern. All the while, the dildo continued to wreak pleasurable havoc on my inside, and I tried my best to continue pleasuring her. My cock was constantly on the verge of orgasm but with no way to go over the edge. After what felt like forever but was probably only ten minutes, Lilith pulled her lips off my cock and said the magic word, "CUM!" before plunging my cock back into her mouth. It felt like an eruption went off in my balls. What could only be described as a literal geyser of cum began shooting out of my cock as my entire body was rocked by one of the most extensive orgasms of my life. It was like nothing I had ever experienced before. The pleasure was, in fact, too much, and though I valiantly tried to hang on, I couldn't. I passed out from the pleasure, and everything went dark.

I awoke to find Lilith staring down at me. I was still fully restrained to the bed, and the dildo was still doing its merry dance in my ass. The only difference now was Lilith. She was now hovering with the tip of my hard cock, teasing her pussy lips. She gently pulled my face up, so I was looking into her eyes as she said, "You pass out from that little pleasure? You haven't experienced anything yet, but don't you worry. After a week of being here, you'll start to adjust to the pleasure, and little things like that won't make you pass out anymore. However, we are just getting started tonight."

She slowly began lowering herself down upon my cock. We both let out a groan of pleasure as my now-massive cock began pressing its way inside her soaked pussy. She continued to lower herself down until her lips were pressed against my balls. Her pussy was incredibly tight, wet, and warm. It felt like it fitted my cock like a glove.

"You think this is nice; just you wait till you get to try my ass. However, that may have to wait for another night, for I still need to do yours," she said as she began riding my cock. It was amazing watching her use her powerful legs to bounce up and down, as she was in complete control. She was able to vary her tempo in whatever way she felt, and yet my cock head never slipped from between her lips. Sometimes she would use fast, hard thrusts, powering me into her depths, while other times, she was slow and graceful. It was magnificent--the best sex I had ever had. I lost track of time as she continued to ride me into sexual bliss, never letting me go over the edge yet always keeping me right at the border. This continued for at least twenty minutes as she played my cock like a fiddle. I was in both heaven and hell, for the pleasure of my cock was like nothing I had ever felt, and yet I couldn't cum. "Do you wish to cum again, my pet?"

"Yes, mistress, please let me cum!" I stated with desperation clear in my voice.

"Then CUM!" she said with an evil smirk. "But don't even think about passing out this time." With those words, my entire body once again coiled up like a spring before I exploded in pure bliss. Every massive jet of cum from my modified cock and balls sent waves of pure ecstasy throughout my body. I could feel it starting to take over like last time, but this time I wasn't going to allow it to overtake me. I somehow managed to stay afloat in the sea of bliss. Since I had missed part of my last orgasm when I had gone under, this was by far the most powerful and longest-lasting orgasm of my life by miles. Finally, after what felt like five minutes and a gallon of cum later, I came to whatever senses I still had left. To my complete surprise, I noticed Lilith, who was still balls deep upon my cock, now showing a small bump around her lower belly.

"Your cock and asshole were not the only things I modified, and before you ask, yes, this is all you cum inside me, and it feels wonderful. You now cum like a prized stallion, my prized stallion." She said as she gently stroked her swollen belly. "However, as much as I enjoy feeling so full, I am not done with you for tonight, and I'm not the one who is going to be going to bed with a swollen belly." To my astonishment, I watched as her bloated stomach disappeared until she was just as skinny as when I had met her a couple of hours earlier.

Then she gracefully stood up, my cock making a loud schlock sound as it left her and got off the bed. To my amazement, my cock was still rock hard. I had never been able to go for more than three rounds before, and not getting even a little soft between games was unheard of.

"Don't look so surprised. I want your cock always ready for my use, so you better get used to it like that. It's not going soft anytime soon. Now, if you thought my cum absorption ability was neat, you're going to get one hell of a kick from my next trick." She then closed her eyes, and a look of great concentration came over her face. Then I saw it happening. Her clit began to change--It started elongating and enlarging. It continued to grow until it was at least three feet long, with a head shaped like that of a horse's dick and over three inches in diameter. Her pussy had changed too, and now, instead, there hung two enormous horse-sized balls.
