Substitute

<<I’m home Fran!>>

<<Finally! You’ve been out way more than I expected. Was everything all right? Did the date go well?>>

<<Yeah relax, the date went great. I’ll tell you everything. But first can you swap us back? Even though I’m now much more comfortable with it, it still feels kind of wrong to be in my sister’s body.>>

<<Oh yeah, sure! You’ve just been away for so long that I kinda got used to this body. I’ll swap us back immediately. Now, where did I put the medallion..? Ah! Here it is!>>

*Flash!*

<<Ah! Much better! Feels good to have my body back. Now tell me, how did the date w… Ouch! What the fuck is wrong with my ass? It hurts and it feels so sore! You… You didn’t…>>

<<Yeah… I may have had some fun while in your body. As I was telling you, the date went on just fantastic.>>

<<You sick motherfucker! You were just supposed to go out on a dinner with Drake!>>

<<And I did. And he was so charming. A real gentleman. I think you’ve found yourself a keeper.>>

<<Quit being so casual about it! You had sex with him!>>

<<Well don’t judge, you weren’t there. I couldn’t possibly turn him down. He was just so nice and considerate. Believe me, it would have been a lot worse to play hard to get.>>

<<You asshole! He must be thinking that I’m some kind of whore! Beside, how could you even do something like that? You’re a sicko!>>

<<Don’t think that it was easy for me. This is all your fault to begin with. You asked me to go on that date in your place in order for you to keep working on your project due next week. You told me to do everything that was necessary to not spoil your chance with Drake.>>

<<I was referring to kissing. Maybe let him grope you a bit. I would have never thought that you would have gone on to do anal with him!>>

<<Well neither of us planned to have sex on the first date, it just kind of happened, and the “back alley” just seemed like the best option. I wouldn’t want to get my sister pregnant after all. Besides, we have something to talk about. I knew you weren’t exactly a virgin, but a well used-up asshole was a lot more than I expected.>>

<<Quit it! It’s not funny! You’ve spoiled everything! Now me and Drake will never get together.>>

<<On the contrary, sis. I think he will never let you go now. We had such an amazing time. We didn’t even get into the car, we just did it leaning on the trunk. It was kind of disturbing at first to have sex while in my sister’s body, but as I got more into it I made the best out of it. Believe me, he will not be able to forget this night for a while. In fact, he already texted you. He wants you to join him in his cottage in the mountains for the weekend. A romantic weekend for you lovebirds.>>

<<Really! That’s… that’s amazing! A whole weekend just the two of us! This is a dream! But wait… I can’t go this weekend. I still have to finish my project. It is too important for my career!>>

<<Really? That’s a shame. Well I can’t make you choose between your career and your love life. I guess I will have to pretend to be you once again for this weekend. There’s nothing I wouldn’t do for my precious little sister after all.>>

<<You asshole! You knew this all along!>>

<<Well, it’s not like you have any choice. And remember it was your idea all along, I never asked for this. But now that I’m into this, I guess I might as well just roll with it and enjoy it while it lasts. Even though I sure hope you will have many more projects to work on in the future. Don’t worry, you can always count on me if you need a substitute. As Drake’s texts will confirm to you, it turns out that I’m quite good at it.>>

Bachelorette party

Oh wow! This… is unexpected. I… I really don’t know how to feel about this. I mean, I’m happy that I found a way to have my brother come to my bachelorette party. Poor soul, he was so sad that he couldn’t join us girls on this night. We’ve always been so close for all of our lives after all. But this was supposed to be a girls-only thing, there was no way my friends would have let him join us. That’s when I came up with the idea of the TG Pill. He would have changed his gender just for this night and pretended to be a distant friend of mine. That would have worked out perfectly. Well, it has worked out perfectly. Maybe a little too much.

I imagined he would have been at least a little bit reluctant to the idea of transforming temporarily into a girl, but he really wasn’t. On the contrary, he seemed thrilled. He looked like he was having the time of his life while we were choosing an outfit for him and discussing the details of his temporary identity. He really took this whole thing so seriously, telling made-up anecdotes about our friendship and really getting into the part. He just looked so natural, nobody would have been able to tell that just a few hours ago he was a guy. And I admit it was a lot of fun to see him act his part so convincingly. But I now realize that this is a lot more than just a little bit of fun for him.

I thought that the moment when the mandatory stripper would have made his appearance would have been the worst part of his experience. I imagined he would have felt uneasy, even grossed out. Instead he immediately was so much into it. When he started to get undressed he squealed and laughed just as all of us, maybe even more. It was so strange to see him act like the wildest and sluttiest of bimbos. He’s my brother after all! But when the stripper got naked and he fell on his knees… well, I immediately knew that this statement was becoming not all that true.

My friends look like they’re having fun at least. Why wouldn’t they after all, she has been the life of the party since the very beginning and she has immediately won them all over. They don’t know that that cocksucker is actually the sweet little brother I grew up with. I don’t know what to think. I’m shocked, and embarrassed, and… I’m not sure about how I should feel about this. I guess I learned a lot about my brother tonight. I just hope I won’t have to order a new bridesmaid dress for the day of the marriage.

A bit of relief

Matt let out a sigh of relief as he put the saddle in its place. He usually would have had no problem carrying it around, but now that he had that frail and petite body it felt like its weight had doubled compared to what he was used to. That of course was not the only reason why he felt so exhausted. It had been a very long and hard day. He had spent the whole morning and afternoon trying to learn how to ride a horse, struggling to have it obey him all the while doing his best not to raise any suspicion about his true identity.

That was probably the hardest part of all, trying to hide all of his frustration and unease while putting on a convincing act. He hated horses, and they probably hated him even more, but now he had to be around them the whole day while acting all cheerful and feminine. Because his sister Ariel loved horses, and she was an experienced amazon. And now that he was trapped in her body he had to act exactly like her if they didn’t want to be found out.

It had been already three days since the two siblings had accidentally swapped bodies due to a magic medallion, and it would have taken other four days before they would have been able to return to their respective bodies. A whole week stuck as each other, a whole week forced to act like the other despite the fact that they could barely stand each other. And the worst part was that his sister even had an upcoming competition in a few days, which meant that Matt would have had to compete as her.

Thank god the practice proved to be easier than he thought. The horses were clearly affectionate to Ariel and were therefore tame and collaborative, and even though he had ridden a horse only a handful of times before, this time it all came pretty natural to him. Maybe it was some muscular memory of that body, or perhaps some magical effect of the swap. Whatever it was, he was glad he didn’t end up getting unsaddled, and if he kept going like that maybe he would have achieved a passable performance at the competition.

To be honest it was a lot more difficult to deal with all the downsides of now being a girl. It felt so unnatural to having to pee sitting, disturbing even, and having to do his hair and makeup perfectly in the morning was a chore, as it did having to act all girly and polite as the spoiled princess that his sister would have done. But he had to admit he had fun pulling the little sister card to get Ariel in trouble when they had a quarrel that morning, and he enjoyed all the attention his parents would now give him. He always knew that Ariel was the preferred child, and now he was basking in all that affection. It also felt pretty nice to ride that horse without his balls getting constantly squashed with every movement. He also really liked his new breasts. They were pretty modest, definitely not anything to brag about, but they were of course new to him, and although alien, they felt incredibly nice. Every time he put on a bra he couldn’t resist the temptation to massage and squeeze them, and it felt so pleasant.

Thinking about that Matt started to feel a sense of arousal. Incidentally the barn was also the place where he hid his porn magazines from his parents, and as he took one out of its hideout he started to ponder. Sure, he had promised Ariel that he would not have done anything weird while in her body, and at first the mere thought of exploring his sister’s body was unsettling and disturbing to him. But it had already been three days, and he could feel the frustration and stress increase with every hour he kept on that farce. It was not like he wasn’t doing his part. He did everything he had to, he deserved some kind of relief. After all what good would it have been to get to the competition all stressed-out? But most of all he was growing increasingly curious about how it would have felt for a girl. “Fuck it! I deserve this!” he thought, and so he opened the magazine to a random page, unbuttoned his jeans, and reached with his petite hand for his groin.

Looking transfixed at the provocative and sensual women in the pictures, he reached immediately under his panties straight for the clit and started to rub it. He soon found out that that would hurt, but he also started to quiver under that touch, and he could feel his legs already going numb. After a while he started to feel a warm feeling down in his groin, and reaching lower with his finger he felt that he had started to get wet. It was so strange, but it felt also so good. He started to play around, teasing the labia a running up and down with his finger, and as he felt the pleasure starting to build he stuck a finger inside of his pussy. It felt so warm, and the slightest move of his finger would make him jolt. It started to move it around, reaching deeper and deeper. Suddenly a moan of pleasure escaped his mouth, and his back arched as a wave of pleasure ran through his body making him jolt. Finally, with his finger now perfectly lubricated, he reached once again for the clit. His dainty finger was now running over it so smoothly, and it felt amazing to tease it, drawing circles around it and rubbing it at an increasingly faster pace.

He suddenly noticed that he wasn’t looking at the magazine anymore, and as he looked once again at those women he realized that those pictures weren’t doing anything for him. So he threw the magazine in a corner and assumed a more comfortable posture. He then closed his eyes and let his mind wonder. He wasn’t even the slightest bit disturbed as he should have been when he surprised himself picturing men in his mind, with toned muscles, and powerful arms, and delicious cocks. And when he stuck a second finger inside his pussy, he was imagining a big throbbing dick penetrating him, and a gorgeous hunk humping him roughly. A few seconds later he reached climax and let out a muffled cry of pleasure, and as he laid on his back transfixed by that experience he realized that he never felt anything like that as a guy.

He quickly composed himself and put everything in its place before heading to the house where his family was waiting for him. Needless to say, the remaining days leading up to the competition would have been a lot more tolerable from that point on.

Sisterly love

“How? How did I end up like this? Please somebody get me out of this!”

<<How do you like it sis? Doesn’t if feel amazing?>>

“I can’t even answer her. I don’t have the energy to do so. Plus I’ve spent the last hour calling them both all the names I could think of. What use would it be to tell her to go fuck herself one more time?”

<<O… Ow!>>

“Goddammit! Why does he have to go so rough?! It hurts!

I… I feel powerless. I can’t fight back. But I can’t just stay here and do nothing while this asshole keeps fucking me!”

<<Why don’t you go a little harder honey? I think she’s ready for some rougher action.>>.

<<N… No! Wait! Ooooh!>>

“I can hear him laughing and grunting behind me. This is disgusting. I feel his cock going in and outside of me faster and faster. I… I can’t even breathe!

This is insane! How could she do this to me? To her own Brother?

Sure, I may not have been the best of brothers, or the most supportive one, especially with her choices in boyfriends. I guess I could have been more tolerant, kinder to them. But how could I just have let her do whatever she wanted? She’s my little sister after all, I have to protect her. I want the best for her, and this asshole certainly isn’t good enough for her.

When I found both of them waiting for me in my bedroom I didn’t know what to think. They were just sitting there, smirking. Then they blew that strange powder in my face and I think I must have lost my senses. I don’t know for how much I’ve been unconscious, but it must have been a while, since they had the time to dress me up in this lingerie and tie me to a chair. I felt so dizzy. It took me a while to even realize that they had changed me into a girl. It feels so strange. These long blonde hair, my new frail figure, my soft skin bruising against the fabric of the lingerie, these two things on my chest that keep swaying back and forth with every thrust. My pussy! It feels warm, and sore!

At first they just made me watch as they fucked on my bed. They said that I had to watch till the end, or they would have left me like this. Then when they finished they came towards me, and started to play with me. They kissed me, and caressed me, and fondled my tits, and pinched my nipples, and rubbed my pussy. I wanted to scream when I realized I was getting wet but I could only moan. It felt so humiliating to realize that I was actually enjoying it.

He then forced me to take his cock in my mouth. I can still smell it. So sweaty. I still feel pubic hair in my mouth. I can still taste his cum. He held me by my hair as he throat-fucked me. It hurt. I was gagging on that thing. I wanted to throw up. The way he was smiling down at me… I felt like crying. I could still cry. Then he erupted into my mouth with his load. It tasted awful, but even worse was its stench filling my nostrils. <<Now swallow it you slut!>> And so I did. What choice did I even have? I’m still not sure how they changed me. My only hope to go back to be me is to do as they tell me. So I swallowed his load subservient. Just thinking about it makes me want to throw up.

But that wasn’t still enough for them. As soon as he was able to get horny again they dragged me to the bed and made be bend over. It was painful to feel his dick penetrating me. It still is kinda painful. I had no idea he was so well equipped. I feel like he could tear me apart! But why? Why?! Why does it have to feel so good?!”

<<Oh my God honey! I think she’s actually enjoying it!>>

“I hate you sis! I hate you so much! How could you do this to me?!”

Brotherly love

I just did what every brother would have done. I guess every brother would have done it at least. I mean, what can you do when you see your little brother getting more depressed and miserable month after month because he can’t get a girlfriend and finally lose his virginity? Hell it had almost become a personal matter. I mean, it is kind of disappointing to have a brother so inept that he can’t even find a girl for a quick fuck. I guess he just lacked the confidence to do so, and I may have played a role into making him so insecure. I may have mocked him one or two times, but what can I say? We have always been just so different.

I guess this makes up for all those times I made fun of him. In fact now I feel more like a fool than ever. I should have just asked one of my female friends to have sex with him, but they would probably have turned him down. They always go on about how ugly he is, or what a looser he is. They may have changed their mind if they knew how huge is dick is. Hell, it’s bigger than mine, it is kind of humiliating.

Anyway popping one of those gender-change pills I had heard so much about recently just seemed like the best solution. If I wanted to really help him I might as well just take it all on myself. I have to say, I turned out pretty attractive as a girl. In fact, when I got my makeup done and slipped into a skimpy dress I was really hot. My brother couldn’t wish for anything better for his first time.

I obviously was pretty tense, if not disturbed, when I approached him at the party. Flirting with a guy was already unsettling, but doing it with my own brother was just way too creepy. I think I did well nonetheless. I reduced him to a babbling idiot in a matter of minutes, just with a couple of alluding sentences and a couple of winks and caresses. Hell, no wonder he can’t get a girlfriend, he’s just so clumsy and awkward.

I was surprised by how confident he suddenly got when we finally got to the bedroom. He had become so impatient, even kind of rough. He almost tore my dress off of me. I have to admit I got pretty aroused by that sudden confidence, which was good, since I was pretty concerned about whether or not I could have actually got through that.

What followed was amazing. I had planned to just ride him for a couple of minutes until he came and then to get away from there and go back to being myself. But instead it was he who ended up dominating me. He bent me over, held me still and slipped his huge shaft inside of me. It cut my breath instantly, and I could barely feel my limbs as it started to dig its way inside of me. Never would I have imagined that sex as a girl would have felt that incredible. The only thing who got me back to my senses was him pulling my hair as he started to fuck me faster and harder. I didn’t plan to become his fuck-toy, but soon enough all I could do was moan, and cry and pant. I think I may have even begged him for more at a certain point. It didn’t felt as unsettling as it does now back then.

In the end I didn’t even leave. I just laid there on the bed exhausted, and fell asleep in his embrace. The sex had been amazing, but now that he was there hugging me from behind, cuddling me and kissing my ear… he was just so cute. He seemed so grateful for what had just happened. I was just too tired to think of getting away as I planned anyway, so I just basked in that tender embrace. I actually panicked when I woke up a few hours later and realized what had happened. Fortunately he was just as tired as I was and didn’t even noticed me gathering my stuff and getting out of the house and back to my place.

In the morning he wrote me about what had happened the previous night. He was just so thrilled, I couldn’t help but smile about it. In the end I really did well. But I’m not sure whether or not I should end it here. After all he may think that he wasn’t good enough if the girl he had spent the best night of his life with doesn’t look for him ever again, and I have still a bunch of those pills left. Becoming his girlfriend is definitely a little bit too much, but it can’t be bad to just see him a couple of times more as a girl and boost his confidence a bit. It’s not like I won’t enjoy it just as much as him, even though the thought of actually starting to date my brother is pretty fucked up. But it won’t be for long, I will just find a way to dump him without making him feel too bad. Yeah, this will work out just fine. I should get a different telephone before that. He will need a mean to contact me after all. Maybe I will get him to send some dick picks. I still can’t believe how huge it was, and they will help me getting myself off when I will start to explore my female body. I don’t want him to catch me unprepared again after all. I must make it clear that I won’t be the submissive one.

Awkward dinner

Mrs. Anderson sighed with resignation. She really hoped that that family dinner would go on smoothly. Admittedly it could have been a lot worse. She was really concerned about how her son Bobby would have behaved. It was the first time that Millicent, the older sibling, brought her fiancé Mike home for Christmas, and she knew how jealous of his sister Bobby could get. She pleaded him to behave and to not throw any scene while they were staying there for the holidays. And much to her surprise he was behaving surprisingly well. The 18 year old boy was polite, easy going and even nice to Mike, more than she could ever ask for. On the contrary it was Millicent who was acting strange. She was taciturn and evidently uncomfortable and she was acting really cold towards her boyfriend. Why? Did they have an argument? Usually she was always overjoyed when they were together. She was really concerned about her, but then again it could have been a lot worse. She was just glad that for the moment there had not been any scene.

Millicent was keeping her head low, her eyes fixated on the plate in front of her, avoiding to make eye contact with anyone. She was well aware that she was the center of the attention in that moment. She could feel the concerned stare of her boyfriend to her left, and to her right her brother Bobby looking at her gravely. Her father started some small talk with Mike to break the evident tension, but as Mike started to respond she felt his hand reach for her leg below the table, caressing her thigh under her dress. A cold shiver ran down her spine. That was too much. She couldn’t handle it anymore. She quickly stood up from the table, excused herself and quickly hurried to the adjacent room, stumbling over the heels she was wearing. Mike was baffled by her reaction, and was about to follow her, but he was suddenly stopped by Bobby.

<<Wait! I’ll check what’s wrong. It probably is nothing. Don’t worry and keep eating, we will be right back!>> he said to him stuttering. There was definitely something strange going on, but Mike did as he said and sat down again.

Bobby rushed to the living room where Millicent was standing in a corner with her arms crossed, upset and murmuring curses. He reached her and took her to an even more isolated room where he looked at her straight in the eyes enraged.

<<Well? What’s the matter now?>>

<<I can’t! Ok?! I just can’t! This is too much for me to handle! You can’t make me do this!>>

<<Do you think I’m enjoying this? Do you think I like to pretend to be my little brother for the holydays? I hate this as much as you, if not more than you. And it’s all your fault!>>

<<My fault?!>>

<<That’s right! And you know that very well! We are in this situation because of your stupid jealousy. Now we’re stuck like this. You heard what grandma said? She’s going to keep us swapped until we learn to understand and tolerate each other. Now I definitely do not want to remain stuck in your body, so you better behave. You’ll go back to the table and pretend to be me and act like a loving girlfriend to Mike. You will do all that is necessary, even have sex with him if it comes to that. Understood?>>

Bobby frowned, making an expression that definitely didn’t belong to his sister’s face. He unfortunately knew very well that she was right. He had no choice. But how could he have acted just like nothing was off?

Eventually they both returned to the dining room where the family was waiting for them. As Bobby sat Mike whispered in his hear. <<Is everything all right honey?>>. He cringed to those words, but he forced a smile.

<<Y… Yes honey. It was nothing.>>

<<I’m happy to hear that.>> said Mike, and gave Bobby a tender kiss. Bobby wanted to puke but he could feel his sister’s gaze behind his back. He had to do what he had to do. The dinner continued pretty smoothly, but he couldn’t help but wince every time Mike reached again for his legs, caressing him and pinching his butt. This continued even after the dinner in the living room. Why couldn’t he leave him alone for a second? After a while Mike got up and said to everyone that he was going to bed. He then whispered in Bobby’s ear <<I’ll wait for you in the bedroom honey.>>

He then winked at him and kissed him passionately. Bobby wanted to push him away and leave the house, but he was met with his former eyes giving him a glacial stare, like his sister wanted to remind him that he had to bear it.

“Ok, I’ll do it. I have to do it if I want to go back to be me. I’ll let him kiss me and grope me all he wants, but nothing more than that!” he thought to himself. “I won’t let my first time be with a man. And trapped in my sister’s body”.
