When my twin sister Lena and I were young we discovered something that at the time was pretty cool. We found out that Lena could turn me into a girl at will, and reality around us would change, so no one would know anything was different. When we were younger we would do this all the time, so that we could play dress up, or play with dolls and generally do all kinds of girly things without anyone judging me or yelling at me to stop.

As we got older and started being teens, I started branching out and doing more boyish things, since I was a boy originally. So I stopped wanting to turn back and forth, especially during a period of my life when I was going through puberty. Lena would often beg me to let her change me, but I would always decline. Eventually she stopped asking altogether. After that we just lived our lives, I honestly went on to forget it was even real.

Several years later and we’re both twenty-eight now. We live in our hometown, but on opposite ends. I’m still single and living alone, and she’s recently married and unemployed due to trying to start a family. We talk every so often, so I’ve gotten to hear her complain about how no matter what she does she can't get pregnant. She mentioned she was keeping track of cycles and all this other kind of stuff, but I have no idea what she was talking about.

Her point was it made no sense for her to not be pregnant. She said her husband got checked and said his sperm was good, so she was starting to think there was something wrong on her end. She started crying while on the phone with me and hung up on me. I decided to be a good brother and drive over to her house with some ice cream and other desserts and sit with her like old times.

When I arrived she was still sorta crying but seemed happy that I showed up. We sat on her couch and devoured everything I brought. Afterwards she still didn’t seem better and I asked her what I could do to make her feel better. That's when she brought up the ability to change me. It had been so long that I thought she was joking, I honestly remember it like it was some silly game we came up with as children. So thinking it was a joke, I agreed to do it.

I was speechless when everything flashed and I was suddenly my sister's double. I guess it wasn’t just a game, but something she could actually do to me. I started remembering all the times we did this as kids. This was very different from back then. When we were kids, the only thing to change was my private parts. Now when I change my body completely changes, giving me a body dentical to my sister's very feminine and mature one.

I couldn’t believe how heavy and big boobs could be. My sister looked amazed, I guess she wasn’t sure if we could still do it or not. She gave me almost no time to adjust before she dragged me to her bedroom. She forced me to dress up in all kinds of her clothes, and I just let her. Afterall it was only for one day and it took her mind off of the whole baby problem. Honestly though, I did have fun with her.

I forgot how nice these sister moments were. I almost regret not continuing it, perhaps we could do this more often. As I was thinking about it, Lena said she had something special that I just had to try. She looked at me and said it was a real good thing that I was the same size as her when I’m a girl. She pulled out this shiny black piece of clothing and brought it to the bed. Then she pulled out a big box, and placed it next to it.

She had me get undressed and helped me squeeze into the clothing she pulled out. It turned out to be a tight latex suit, one with cutouts in the front and back for sex. Once I was in it, she zipped it up. She asked me how it felt, and I was surprised at how good it felt. It was extremely restricting, but the way it hugged every part of me, including my breasts really turned me on. Lena looked at me and said she knew I’d be into it.

She then said she was going to put the rest on, and not to worry as she would take it off afterwards. I agreed, afterall it was my sister, and I know she wouldn’t do anything weird other than showing me all this. She pulled out a mask that matched the suit I was wearing and put it over my head, then she put a ball gag into my mouth, locking both into place. Then to finish it off, she put cuffs on my arms and legs and locked me to the bed frame.

She said she was going to step out for a minute and let me enjoy her sexy suit, then she would come back in and help me take everything off. It only took a few seconds after she left for me to feel incredibly awkward and uncomfortable. I have no idea why I let her do this to me, now that I’m bound here I definitely think this was too much. I guess I can tell her that when she comes back. A few minutes pass and she doesn’t return, I start freaking out a bit and trying to get free.

As I’m trying to get free, I hear a deep male voice say “what do we have here.” I lift my head and see my sister's husband standing in the doorway. I start trying to talk to him, but with the ball gag I can’t get anything out. He entered the room and closed the door. “You sure are trying hard to get pregnant, well huh, I have a feeling tonight night.” Then my sister's husband did something I was not expecting to be a part of.

He removed his clothes and jumped on top of me. He started playing with my tits and I was suddenly in a world of pleasure. I was trying to tell him I wasn’t his wife, but as he played with my tits, I went from trying to stop him to begging for more. He caressed the tight latex around my waist and then he slowly inserted his massive dick into my virgin vagina. He held my waist tightly as he pounded me. We rocked the bed back and forth for about twenty minutes.

He finished and got off of me, then she used the keys on the side of me to unlock me from the ball gag and cuffs. As soon as I was unlocked I ran out of the room and into my car. Still wearing the latex suit I speed back to my house. As I sat in my car, I got a call from my sister. She asked me where I was, and why I left. I was too embarrassed to talk about what just happened so I made up an excuse and told her to just come see me the next day.

I go inside and remove the suit and lay in bed. I didn’t even care I was still the female version of myself, I just wanted to go to bed and forget about this day. The next day comes and my sister comes to visit me. She immediately apologizes for embarrassing me in front of her husband, telling me she had no idea he would get home early. She then apologized that I was so embarrassed that I left in her latex suit and didn’t even get the chance to turn back.

She then tried to turn me back, but nothing happened. She looked confused and began to freak out, she had no idea why it wasn’t working. She kept telling me she would figure it out and return me to normal. I turned beat red as I told her I had a theory as to why I couldn’t turn back. I told her about how her husband didn’t just unlock me. She looked horrified when she found out her husband had technically cheated on her with her sister.

She then asked why I thought that was keeping me from turning back? Then she realized it herself, her husband thought I was her tied up on the bed. So he didn’t use a condom, and I was likely pregnant. She went from being mad at her husband to super happy for some reason. She told me this was perfect. I was confused, saying this was awful for me, so how was it perfect. She then reminded me she was trying to start a family.

So since she was under the assumption she couldn’t bear children, she would be more than happy to adopt mine. I told her that was a lot to ask of me, and I’d prefer not to be pregnant, and take the pill to cancel it. She got on her hands and knees and begged me to do this for her, and I ended up giving in. So that day we went back to her house and confronted her husband. He also began apologizing to both of us.

He had no idea it was me, and he was so ashamed and embarrassed he lied about it to Lena. He said it would never happen again. Then we told him about how I was likely pregnant, and he seemed worried, but then acted happy. He was definitely hiding something, but at the time neither my sister or I knew what it was. It took months to find out his last little secret. It turns out the reason my sister couldn’t get pregnant was because he had a vasectomy. 

It just so happens a few nights before we had sex, he had it reversed. He didn’t plan on telling my sister, and he just intended to get her pregnant and act like nothing happened. So that night he also got her pregnant. So now we're both pregnant with his kids, which is just a whole mess. By the time we found out that Lena was pregnant, it was too late to terminate the pregnancy, so I was forced to carry this baby.

At first it was awful and I hated it. By the time I was days away from my due date, that had all changed. I had become ready to be a mother, and I couldn't wait to see my baby girl enter this world. My sister is expecting a boy, and is super excited about finally getting her family. We also became much closer as siblings, as we spent almost the entire pregnancy together. I kinda needed her to be around constantly since I had no idea what I was doing.

Here we are in this photo, the final photo we’ll likely take before giving birth. I don’t really know what life will be like afterwards, whether or not I’ll change back or even if I’ll be able to. At this point I don’t think I want to anymore. I’ve come to realize that I like this female body much more than my former male one, as the perks and pleasures are so much better. Plus dressing all cute feels amazing. I think I’ll at least try out motherhood, I mean who knows what would happen to my baby if I change back now, and just the thought makes me sad.
