The Future She Gave Me, part 1

My sister, Lily, and I were about five years old when our mother died. Before she passed my mother pressed me to look after my sister and make sure that she would be safe. My dad always reminded me of this as well, and as a result I always have felt obliged to do so. Looking back, I might have been too protective of her, but my intentions had always been good.

A few months ago, my sister came to me and confided that she felt very uncomfortable with the way some of my friends were staring at her all the time. She said she felt like they were undressing her with their eyes, and that she didn't appreciate it. In a sort of ultimate contradiction, I brushed aside her fears, and even though I had protected her all those years, I refused to do so now that she was asking for it herself. However, I didn’t want to believe it and trusted that my friends weren’t like that, and because after a while she started talking to me about it, I assumed it had passed.

In hindsight I should have noticed that the relationship between my little sister and me changed noticeably after that, but I had not noticed it at the time. I still told her that she might be better off not wearing certain things when she went out; I still made her breakfast in the morning; and when she left, I still asked where she was going and with whom, while also making it clear that she had to be home by certain times. However, Lily became increasingly less willing to accept this from me, and I felt the distance between us grow.

A few weeks back everything changed, as I talked to Lily after she was home late again. I had called her several times, but got no contact and I even tried contacting her friends to find out where she was and if she was okay. However, she interpreted it as me playing for mother, and we got into a big fight.

After she had walked away and I heard all kinds of noises coming from her room, she returned walked up to me and handed me a small box. She said she was sorry and said it was for me. She pushed me to open the box, and when I did, I was uncertain what to think when I saw the watch. I moved my finger over the watch and grabbed it, and when I looked up, I saw the expression on her face had changed from, what I had assumed, remorseful to an evil grin. I asked Lily what was with the woman’s watch to which she replied “as you always tried to play a mom it will suit you, as perhaps you should be actually try and become a mum,” she said.

I failed to understand it and look at her standing in front of me with her devilish grin. “What the hell do you mean?” She looked me over and said “I am sick and tired of you acting like a mother, and despite me not asking you to behave like that, you continued. The moment I really asked you to step forward as my brother you refused to believe me, so perhaps the role of a mum suits you much better.” I looked at her in confusing and disbelieve. “Don’t worry, you’ll understand it in a moment, when the changes will begin. The moment you touched that cursed watch you sealed your fate,” she laughed.

Seconds later I started to feel nauseas while the entire room started spinning. “What do you like more big tits or smaller ones,” Lily asked me teasingly. I however felt to sick to answer and could hear he say “you definitely are into the bigger tits. I see how you always look at Andrea her assets when she comes and visit me.” I could not admit it now, but her friend Andrea definitely had big breasts, which caught my attention more than once, especially if she wore something revealing. “I have enchanted the watch to make sure that you will get nice “assets” and traits no matter what, but there if I udnerstood correctly you will have some say in how you will turn out,” Lily laughed out loudly. Adding that I would definitely get some fine wide thighs, as “those will be needed to bear children” and she revealed I would also get an insatiable desire for cocks and getting rammed hard and often. “To top it off, you will definitely want to get filled over and over again. As getting bred and getting a bun in the oven is such a strong desire for you,” Lily smirked. I could feel my mind slowly alter after her words. Was she right?

I felt it was difficult to concentrate and with every passing second my mind became more cloudy. Suddenly I felt a strong itch on my scalp, and in the glass of the kitchen cabinet I saw my own reflection getting longer and longer hair. I reached to my forehead and pulled my lengthy strands of brown hair. “What the fuck?!” I shrieked with an unfamiliar voice. It sounded far higher pitched than I recognized and as I watched Lily grin deviously, I realized it had become a voice far more suitable for a woman. “Are those your facial hairs and stubbles disappearing?” Lily questioned and I immediately turned to the reflection again seeing my face get softer and smoother.

I felt like I needed to throw up, but nothing was coming up. All the while, I felt my body became more feverish and tingly. As I kneeled on the ground, the room around me seemed to get bigger and bigger. It felt like my body was getting smaller, I felt the strength fade and get weaker. Slowly my clothes disappeared and I panicked as it revealed more and more of my smoother, hairless skin. I went into full panic mode as my t-shirt formed into a white bra which was far too big for my chest. My boxers than started to become quite uncomfortable as they were getting too small for my slightly expanding hips, thighs and ass. Moments later my boxers turned into a woman’s panty. As I asked myself what was happening and trying to make sense of it all, I felt a sudden sting in my hips and I let out a high-pitched shriek, which sounded even more female than before.

Suddenly my hips flared outwards, while I felt fierce stings inside my abdomen. “Don’t worry about that,” Lily smirkingly remarked. “That is just your body making space for your new birth canal, you need some more room hence the widening of your pelvis,” she laughed. When the pain subsided, I opened my eyes and let my hands travel from my mouth down to the womanly hips I now sported. Still comprehending what had happened, I felt a now familiar sensation build up in my chest. Under my bra, fat and tissue started to gather and press up under my swollen nipples. My hands shot to my chest as the pressure grew. Two soft, fleshy mounds began filling my bra and pressed against my hands. I knew what was happening to me now, I was getting breasts and turning into a woman.

I thought to myself that this had to stop, while bringing my hands to my newly formed breasts. My breasts had become small A-cups and as I moved my hands over them I tried to push my growing breasts back into my chest, letting out a feminine groan as I pressed them. Instead of getting smaller my breasts grew into perk B-cups, while they even became more sensitive to my touch. Each movement of my fingers over them resulted in me letting out more groans. I growled as my fingers pinched my stiff and hard nipples, while my breasts grew further into C-cups. “You better control yourself somewhat, you dirty slut. If you continue to touch them, they will grow even larger,” I heard Lily say. Despite my mind saying I should stop, the urge to touch my sensitive breasts was just too much, and I continued to squeeze and press them. As a result they grew even larger into lushious D-cups, while I let out an other powerful groan as my left nipple was suddenly pierced while I was pinching my hard nipples.

La Sirena showing her assets

MMM those babies will definitely help you seduce all those horny and fertile young men,” Lily laughed, adding that those boys would however like more than just my beautiful D-cup breasts to play with. Immediately I felt more changes hitting me, with my ass beginning to change as well. My ass began growing just like my breasts had, and my panties soon strained against my curvy, girly behind. I looked down at my new curvy assets, and tears began to form in my eyes, as I realized what was about to happen. “No, please stop! Please make it stop!” I looked at my little sister Lily, who had a devious smirk on her face. I grabbed the bulge in my panties, and noticed it began to shrink rapidly. “Don’t worry, this is what all those horny men prefer, as they will love ramming their rock hard cocks into that tight and wet void of yours,” she said.

At the same time my legs started to burn, and I suddenly lost the ability to stand on them. It felt like they were turning into jelly. After I had regained control over them and stood up in our kitchen again the burning in my legs got stronger and the last hairs started to disappear. Following that I could see my legs grow in size and expand, especially my upper legs seemed to get thicker. The heat radiated through my thighs and behind and before my eyes I could see them expand. “Mmm, those thighs and hips are more and more turning into what they are intended for; producing babies,” I heard Lily giggle. And all I could think of was that she was right…. I let out a loud cry as I felt a new opening form under my scrotum. I felt my testicles retreating up inside me, sending shivers up my spine. I panted, cried and groaned, sounding very much like a woman now. I grabbed my ass as it spread even further and felt my new vagina tunnelling its way into existence. I felt a bliss as my fertile uterus formed in my abdomen, my newly formed uterus was almost instantly joined by my testicles who had transformed into my ovaries. While my scrotum finally reshaped into my tender labia around my newly formed wet new hole, giving me a euphoric intense feeling. I ultimately came as a woman for the first time when I felt my cock dwindle down to just a clit and assume its new position, and my hand almost instinctively started to stimulate my new clit in a response to the transformation process.

Showing my new pussy

Lily looked me up and down, and nodded approvingly. “What have you done to me, I never…” however before I could finish my sentence, Lily told me to hush and placed her finger on my forehead. Almost immediately my mind started to race, and I was struck by an immense headache. “Sshhh, it will all be alright. After the reconnection has been made, you will not remember anything of your previous life. All you will know is being Maria Antonella, my stepmom. Playing mom like you always wanted to do,”Lile explained. I looked at her and pleaded “please, no, no don’t do that, I don’t want that.” Lily grinned deviously and responded “I know that’s not what you want; you want to have your own children, to have your fertile womb filled with warm, fertile and potent seed. Unfortunately, Daddy has gotten helped, but luckily your former friends are only too willing to help you out. And otherwise my friends want to help you to. Once the reconnection has been made you’ll sole desire will be to help me and protect me by letting them act out all their horny and sexual fantasies on you, instead of on me, Lily laughed. I had tears in my eyes, as the last pieces of my former life were deleted from my memory and replaced with new memories.

As I stood there huffing and puffing from the entire thing and had regained myself somewhat, I noticed Lily was looking at me with satisfaction clearly visible on her face. “You turned out quite beautiful……mom,” she said. Somewhere deep down I could still feel my male self try and fight back, but my new identity was far stronger. “Ahh, don’t worry that version of you is not going to return anymore, Maria Antonella,” I heard Lily say. I immediately recognized my new name, but also deep down felt a need to cry out that I did not want this. As I struggled to comprehend the situation I was in, Lily broke the silence and said “although you are gorgeous to look at, perhaps it would be wise to get dressed. Otherwise if one of my friends shows up, they would definitely feel the need to play with you and we wouldn’t want that to happen, wouldn’t we?” I saw the teasing expression on her face as she said that last part, as she definitely noticed my doubt about it. I felt my entire body react the moment she said one of her friends would definitely get the need to play with me…. She tossed me some clothes and I started to move towards my room to get dressed.

Sexy walk to my room

As I was deciding what to wear, I felt that her teasing remarks had seeped into my mind. Images and memories started to form as I was checking myself out in the mirror and deciding what to put on. I started to remember many situations where her friends had checked me out very openly and thoroughly and made numerous flirtatious remarks, some even went further and were outright sexist. However while I should think negatively about it, especially those last ones, thoughts started to trigger reactions throughout my entire body. Remarks about grabbing me up, throwing me on a table and fucking my brains out, these started to cause my pussy to get wet, very wet. My male self-conscious tried to fight it, but the desire to get fucked hard by these boys was rapidly becoing overwhelming and I felt it in every fibre of my body.

I soon started investigating and getting familiarized with my new equipment, which quickly escalated to desperate rubbing and fingering. I bit my lip as I rubbed circles on my hot pussy while feeling up my body and my sensitive breasts. I was well aware that Lily was still somewhere in the house as well, so I attempted to stifle the moans and groans, which I let out. My body craved for more than what my fingers could provide, and I began fantasizing about several of Lily’s friends. Images of their cocks and sex with them filled my head and I moaned out loudly while fingering myself.

Some little me time

Suddenly I heard a knock on the door and I heard Lily ask if everything was okay. My male self-conscious knew immediately that this had been her entire plan, to make me even hornier and to make this al a little game for her, however Antonella soon took over again and I remembered that I had told Lily that I would help her out with something. I told Lily I would be with her in a moment, but that I couldn’t find what to wear. Still hazy and horny, because I could not get finished, I went to the bathroom and fitted out several dresses, feeling up my thighs, hips, ass and breasts more than once.

Deciding what to wear

I ultimately decided to pick a dress that accentuated all my assets perfectly and as I had been unable to help myself I had felt the urges build up inside me, making me even hornier than I had been before. Still unsure what Lily had been needing my help for I walked into the room again.

Acting all innocent

As I walked in Lily laughed and asked if I was finished, her face clearly showing signs that she knew I was helping myself when she knocked on the door. “Kinda hot to think I could walk in on you” she grinned. "Where you helping yourself, or fantasizing about some of my friends," she asked laughingly. I quickly responded that I had no idea what she was talking about, but felt a tingling in my stomach the moment she said it. She was not wrong at all, it would have been even better if one of those friends would walk in and just fuck my brains out my I thought, however this was quickly countered by my male self-conscious. “This is exactly what she wants me to do, that evil bitch,” my male self-conscious screamed.

Ahh, too bad,” Lily said, “I know that Yahshua and Rico would definitely not had the door remained locked as I did,” she laughed with a teasing grin. “What do you mean,” I asked her. “Oh Antonella, you know very well they would both jump at the chance to play with those delicious tits of yours, to kiss and suck your nipples, to lick you and ram their hard cocks into you,” Lily said, and I immediately felt my body react and felt tingles all over due to every single word she said. While my male self-conscious screamed to get her to shut up and quite with the nonsense, I could only ask her what she meant exactly. “Those two have had the hots for you since forever, heck they even have asked me for pictures of you, Lily said. “Pictures?!? I asked. “Yeah even yesterday they asked for pictures of you,” Lily replied.

My mind raced as these two young boys apparently had an interest in me. The thought of that made me even hornier, as I started to feel the sensation in in my stomach again. “What are you think, and why are you holding your stomach,” Lily smirked, as apparently instinctively I had brought my hands to my stomach during the process. “They are definitely willing to help you out with that baby dream of yours, but that will be a little hard to explain to dad, wouldn’t it,” Lily laughed. “What, wha….what do you mean?” I stammered. “I have heard you and dad argue and fight about it in the past, and it is only logical that you want to fulfil your task as a woman to make babies, Lily said with a devious grin. Her words fuelling my desire to do so to an incredibly high level, something that Lily could immediately see in my eyes. “Yahshua and Rico overheard a fight between you and dad some days ago as well, and told me several times since then that they would have no issues with helping you out,” Lily grinned. The thought made my knees weak, which Lily seemed to notice as she looked at me with a calculating expression. My male self-conscious hit the alarm bell, however Antonella felt more powerful and the desire to make babies quickly overpowered me. “We can tease them a bit, and see if they will put their words into action,” Lily asked me while biting her lip provocatively. Before I had thought it over I agreed to do so.

Lily took her phone in hand, and I started to talk into the camera, provocatively daring them, while I gradually revealed my 80D cup breasts on video. At the same time I showed off my curvy behind, while smacking myself on the butt and stating that it would be much better if they would do it. During the recording Lily invited both of them to come and put their words into action, before sending them the recording.

Making a video

After a while Lily said that both of them had viewed the video, but she had not received any response. As we both assumed that they both were too scared to actually do what they have said, we sat there and talked some more, before Lily stood up and whispered in my ear “guess we will have to find another way to fulfil those baby needs of yours and make this permanently….

My male self-conscious screamed out that I should not give in, and realizing there still was a way back from all this, but the female me, Antonella, feeling left disappointed and still extremely horny from everything that had happened.
