01 — Marketa

I have a problem.

A pretty big problem, actually, and I have no idea how I’m supposed to solve it, because whatever I do feels like the worst decision in the world.

I’ll get straight to the problem first, and then I’ll try to make sense of it.

My name is Marc, I’m twenty-three, and my twin sister, Marketa, who’s also twenty-three, has proposed something to me: she wants us to go for a drive so she can suck my cock.

Obviously, it’s not that my sister is some kind of sexual deviant, and she didn’t put it to me quite that bluntly. In fact, that’s exactly the problem. Marketa is incredibly shy, and guys make her nervous. Well, maybe I’m exaggerating. It’s not that she’s actually afraid of guys; it’s just that doing certain things with them scares her. She just explained to me that she’s given handjobs before, but when it comes to going any further, she freezes up. That’s why she’s asking me for help.

Obviously, it’s a terrible idea. The problem is that whatever I do, I’m going to feel awful. If I refuse, I’ll feel terrible because my twin sister is asking me for a favor and I’ll literally be telling her no, despite how close we are. But if I agree… I don’t know. She’s my little sister. Sure, she’s only my little sister by a few minutes because we’re twins, and yes, she’s twenty-three years old, not a kid, but still…

The thing is, I understand her.

I suppose that’s the worst part.

The real problem probably goes back to our mother’s work, but I’ll take this one step at a time.

As I said, my name is Marc. I’m twenty-three, dark-haired, tall, and good-looking. I’m in great shape, my abs show, and girls at college tend to like me. I don’t want to sound arrogant, but it’s true. Unlike my sister, I’ve had plenty of sexual relationships, some of them with friends of hers, and everything has always gone fine.

Marketa, my twin sister, is twenty-three and was born a few minutes after me. She’s dark-haired too, incredibly beautiful, funny, and although it feels strange talking about her body, the simplest way to put it is that she’s slim and gorgeous. We both have Czech roots because we were born in the Czech Republic before being adopted by our American mother.

Our mom, Jessa, is your classic successful American. She owns several restaurants across the country, which meant we had to travel quite a lot when we were younger, although we’re both at college now.

I live on a coed college campus, surrounded by both guys and girls. My sister’s campus is a completely different story. Since she’s studying fashion, women vastly outnumber men there, and according to her, most of the few guys she does meet happen to be gay.

We haven’t been seeing as much of each other lately, which I suppose partly explains her proposal.

Anyway, I ran into her at college today. That happens sometimes, so there was nothing unusual about it, except she looked worried—or perhaps thoughtful would be more accurate.

“Bro, can we talk for a second?” Marketa asked.

“Sure.” I let my friends carry on without me and stayed behind with her to find out what she wanted. She sighed, looking as though she didn’t quite know how to say it.

“Don’t worry, nothing’s wrong. But I’m going to text you this afternoon because I want to ask you something, okay? I’m just warning you now so you know it’s really me,” she said with a smile.

“Okay, sis.”

And that was it. Everything seemed perfectly normal afterward. I went off with my friends and she went back to hers. I assumed—incorrectly—that she wanted to organize some kind of party with our mutual friends, or perhaps that she liked one of my friends.

I was wrong.

I’m not going to copy and paste the message she sent me because it was ridiculously long, but there were essentially three important points.

First, she knew what she was about to ask wasn’t exactly normal, but because we’re so close, she hoped I’d understand. Second, she made it clear that if I wasn’t comfortable with it, she’d understand completely. And third, she started explaining that she’d hit a kind of sexual block and wanted to know whether I could help her overcome it.

She went into a lot of detail about that last point because we’d never really talked about sex before. Basically, she told me she’d been trying to have sexual relationships with guys and had no problem giving handjobs, but the moment she tried to put a cock in her mouth, she froze and couldn’t do it.

I’m not going to lie: the moment I realized where the conversation was heading, I went back to my room on campus by myself and just sat there thinking. Of all the conversations I’d ever imagined having with my twin sister, talking about sex had never been one of them.

Basically, Marketa told me she’d been meeting guys, but all her relationships ended badly because she never wanted to do anything. It took her a long time to explain everything, but that was the gist of it.

I told her I was sorry and asked how exactly she thought I could help. She replied:

“I know this isn’t something brothers and sisters normally do, but could you help me get over my fear of putting a cock in my mouth?”

I stared at the message in shock for a while before finally asking how exactly I was supposed to help her.

“Could you get the car and take me for a drive and show me?” she replied.

She hadn’t literally said she wanted to suck my cock, but the implication was obvious.

“Okay. Give me a couple of days, and then we’ll go, all right?” I wrote back.

She thanked me, and just like that, we’d made plans for two days from now.

My answer had been much faster than it should have been, mostly because I didn’t want to hurt her feelings, but now I’m incredibly confused. If I hadn’t seen her at college today—if she hadn’t specifically warned me that she was going to message me about something—I would’ve assumed someone had stolen her phone and was playing some elaborate joke on me.

So that’s my problem. I have absolutely no idea what I’m going to do, and this certainly isn’t something I’m going to tell anyone about. I think my plan is to meet her somewhere private and actually talk through it properly, because going along with her idea doesn’t seem sensible. But abandoning her when she’s come to me because she trusts me doesn’t feel right either.

So… I don’t know. I genuinely don’t know what I’m going to do. I’ve got two days to think about it, and I’m going to need every minute of them. For a moment I considered asking one of my friends to help her instead, but somehow that feels even worse, almost like I’d be rejecting her and handing her problem over to somebody else.

So no. I’ll think about it. We’ll see.

Because yes, Marketa is beautiful. Physically, she’s pretty much perfect.

But she’s also my twin sister.

And I need to figure out what the hell I’m going to do about that.

02 — Getting Closer to My Sister (Two Days Later)

Okay, I have a problem.

A very pleasant problem to have, admittedly, but a problem nonetheless.

The problem is figuring out how I’m supposed to keep seeing my little sister as just my sister after the incredible blowjob she gave me today—and after discovering how much we both seemed to enjoy the experience.

I’ll start from the beginning and explain exactly what happened.

After spending the last two days thinking about it from every possible angle, I eventually decided the best thing I could do was stop agonizing over it and just get it over with. So this afternoon, after lunch, I picked Marketa up in my car. She looked absolutely gorgeous, and we drove somewhere well away from the university, to a secluded place where people sometimes park to have sex. It’s a huge open overlook with a view of the entire city in the distance, and I’d been there myself with girls before.

When we arrived, Marketa looked at me with that bright smile of hers. We were both obviously a little nervous, so we talked for a while about how weird the whole situation felt and how we thought it was going to go. Then, because there really isn’t a more delicate way to put this, my little sister got onto her knees on the passenger seat beside me, put my cock in her mouth, and started sucking it.

I’m not going to lie—it was incredible. Watching my twin sister close her eyes as her head moved slowly up and down, her mouth working around me, was something I never expected to enjoy as much as I did.

And I know how wrong that sounds. I know. But she treated the whole thing with such a playful, almost lighthearted attitude that eventually I came in her mouth and she swallowed. When she stopped, we both burst out laughing, and then she gave me this incredibly happy hug and told me I was the best brother in the world.

But I should probably explain the whole thing properly, because the reason I enjoyed seeing my little sister sucking my cock in the car so much wasn’t just the physical side of it. It was the dynamic that developed between us and the things she said.

I’d been incredibly nervous all day. I’d made an unusual amount of effort getting ready, even grooming myself down there, and tried to prepare myself mentally as best I could. I’m not going to lie: I’d been anxious about this for the entire two days.

When I picked Marketa up at the agreed time, though, she seemed much more relaxed than I’d expected. She looked amazing, as Marketa always does, with her perfect long hair and that cheerful expression she always seems to have.

During the drive, we just talked. Family stuff. College. When the two of us were going to visit Mom again. Completely ordinary things. If you’d overheard us, you’d never have guessed we were driving to a secluded spot so my sister could suck my cock.

By the time we reached the overlook, I’d started to relax too. We kept talking about random things for a while after I parked, until eventually I realized one of us was going to have to acknowledge why we’d actually come.

“So,” I said, still half hoping she’d tell me she’d changed her mind, “how do you want to do this?”

Marketa laughed. “I honestly don’t know. How do you normally do it?”

She seemed a little nervous, but nowhere near as much as I’d expected.

I explained that normally a girl would touch a guy through his pants for a while, wait until he was hard, then take it out and start sucking him. It felt incredibly weird explaining that to my sister, but that’s what I did.

“Okay, then I’ll do that, and you tell me if I’m doing anything wrong, all right?” she said with a nervous laugh.

“All right.”

Marketa reached over and started rubbing me through my pants. I’m not going to lie: I got hard much faster than I’d expected. I’d thought being with my sister might make it difficult, but apparently not. After a while, while she was still touching me, I asked whether she wanted me to take it out or whether she wanted to do it herself.

“You do it,” she said.

So I leaned back slightly in the driver’s seat and took out my cock, already big and hard, showing it to my sister for the first time.

Her reaction caught me completely off guard. She laughed nervously and stared at it.

“Jesus, bro. How the hell do you expect me to put that in my mouth? It’s huge!”

Her nerves were obviously making her laugh, and I couldn’t help laughing too. I explained that she didn’t have to put the whole thing in her mouth, just the tip.

Marketa took things very slowly. Still smiling, she touched it first with one finger, then wrapped her hand around it and started playing with it, examining it with obvious curiosity.

Then she said something that caught me completely off guard.

“Jesus. Now I understand why Mireia liked fucking you so much. It’s perfect.”

She said it with a nervous smile. Mireia was an old friend of hers I’d slept with a couple of times years ago.

I’m not going to lie: hearing your own sister tell you your cock is perfect while she’s holding it is a very pleasant sensation. I thanked her, and she kept playing with it.

She took her time. I could tell she was struggling to work up the courage, but I didn’t say anything.

To be honest, at that point I wasn’t even completely turned on despite being rock hard. I was mostly watching my sister play with my cock as though it were some strange new toy.

Then she smiled, blew out a breath, and nodded to herself.

“Come on. I can do this. Here goes.”

She shifted onto her knees on the passenger seat, and I watched her lower her head toward me.

The first thing she did was kiss it. Then again. And again. Then, without warning, she put the tip in her mouth and started sucking while holding the base between two fingers of her right hand.

I’m not going to lie: I just sat there with my mouth open. Watching your twin sister put your cock in her mouth for the first time and slowly start sucking it with her eyes closed is one hell of a thing to process.

I checked the mirrors to make sure we were really alone. The last thing I wanted was someone turning up and catching my sister sucking her brother’s cock—my cock. But because it was still afternoon, the place was completely empty. It normally doesn’t fill up until nighttime, when young couples start arriving in their cars.

The first few minutes felt surreal, and it took me a while to relax. But once I did, I have to admit that watching Marketa suck cock was beautiful.

It was only then, with my sister between me and the passenger seat, that I really registered just how beautiful she was. That Czech face, that smile, that slim, perfect body. Once I’d adjusted to seeing her in such an unfamiliar position, I started stroking her hair and back. She didn’t react; she simply kept going.

After a while, she stopped and looked up at me with a smile.

“Am I doing it right?”

We both laughed.

“Marketa, you’re doing amazingly. I love it.”

“Really?” she asked, smiling.

“Seriously. It’s incredible.”

I meant it. I could tell she liked hearing that. She thanked me, then closed her eyes and went back to it.

That was when something clicked in my head. I knew I wanted to repeat this because the experience felt incredible. The physical pleasure was intense, obviously, but seeing my little sister so happy while she was doing it made me start telling her how good she was and how beautiful she looked. Every time she glanced up at me, she smiled.

Then I said something without really thinking it through.

“Marketa, would you help me get better at going down on girls?”

I was incredibly turned on, watching my sister’s head move rhythmically as she slowly sucked me.

I’d mostly said it on impulse, but she stopped for a few seconds and looked at me.

“Oh, I’d love to. Besides, nobody’s ever gone down on me,” she said with a laugh.

“Seriously?”

She nodded, and we ended up having a short conversation about it. She explained that the idea made her nervous, but that she wouldn’t mind trying that with me too. While we talked, she slowly stroked me with her hand, smiling the entire time.

Eventually she explained that part of the reason she wanted to learn how to give blowjobs was because she wanted guys to go down on her in return. Then she went back to sucking me.

By then I was much more relaxed. Marketa had been doing it for a while, we’d somehow had a conversation about me going down on her, and she was still there with me. Completely turned on, I said:

“My God, Marketa, you’re the best sister in the world. I love watching you suck cock.”

She stopped for a moment, looked up at me with a huge smile, and said, “Aw. And you’re the best brother.”

Then she leaned toward me and gave me a quick kiss.

Afterward, she smiled happily and went back to what she’d been doing.

Strangely enough, that little kiss felt more intimate to me than the blowjob. It was such a simple, genuine display of affection.

Seeing how much she seemed to enjoy hearing nice things from me, I groaned softly and told her, “I wish I had a girlfriend like you. Someone as beautiful and perfect as you.”

I stroked her hair as I said it. She kept going with her eyes closed, but I saw the corner of her mouth curl into a smile.

The whole experience had become strangely affectionate. Sweet, even. She was pleasuring me slowly and tenderly while I stroked her hair, and that made me start saying all the things that were running through my head.

“You’re so beautiful, Marketa. You deserve all the love and affection in the world.”

She smiled.

“You’re the most beautiful thing in the world.”

Another smile.

“You’re gorgeous, Marketa. I love you so much. I’d do anything for you.”

That last sentence seemed to affect her. Marketa became emotional, stopped what she was doing, leaned toward me, and gave me a quick kiss. Then another.

And then we started making out while she stroked me with her hand.

My sister was emotional.

I honestly don’t know which felt more intimate: watching my twin sister suck my cock in a car or feeling her tongue in my mouth while she slowly gave me a handjob.

We kissed deeply. She breathed heavily as I slipped my tongue into her mouth, then I felt hers against mine while her hand kept moving.

It was there, making out with my twin sister in the car while she stroked me, that I realized sooner or later we were probably going to have sex. I loved her, and I could feel that she loved me too.

I don’t know how long we stayed like that, kissing each other affectionately, but I loved it. More importantly, I could tell she loved it too.

Eventually she stopped, looked directly into my eyes, and said with surprising intensity, “Thank you for treating me so well. You’re the best brother in the world.”

Then she went back to her knees and started sucking me again, this time with a kind of tenderness that hadn’t been there before.

It felt different. Earlier, she’d seemed like a sister trying to learn how to give a blowjob. Now it felt as though she was doing it because she wanted to be something more than just my sister.

It was incredible. The tenderness of it somehow made me even more turned on, and I found myself talking to her again.

“You really are the best sister in the world, Marketa.”

“I love this. I love seeing you with my cock in your mouth. We have to do this again.”

“I hope I can give you as much pleasure as you’re giving me.”

Every time I said something, she smiled while I stroked her hair.

Eventually, of course, everything has to come to an end.

“Marketa, love, I’m going to come. Should I put on a condom?”

It was the first time in my life I’d ever called her love.

She looked up at me with a mischievous smile.

“Good sisters swallow their brother’s cum when they give him a good blowjob.”

Then she put me back in her mouth.

I’m not going to lie: in that moment, I knew whatever was happening between us was serious. She’d said it playfully, teasing me. In fact, those words were part of the reason that, when I got home later, I told a girl I’d been casually sleeping with that we needed to take a break and stop seeing each other.

Anyway, to cut a long story short, I came in my sister’s mouth and she swallowed with a huge smile.

And then?

A few seconds later, we both started laughing.

The tension was gone. We started talking, and I asked her how she felt.

“I liked it much more than I thought I would,” she admitted with a huge smile. “What about you?”

I told her I’d loved it too, and we stayed there talking intimately in the car for quite a while. Eventually she looked at me, still smiling.

“We have to do this again. Seriously. I don’t know what happened, but I loved it.”

I asked her why, and she tried to explain, although I don’t think she entirely understood it herself. What she did know was that she loved giving pleasure and knowing that I was enjoying what she was doing.

We ended up talking for nearly two hours.

Stripped down to its essentials, what Marketa told me was surprisingly simple: she loved hearing sweet, affectionate things while she was giving someone pleasure. Nobody had ever made her feel like that before. She loved my cock, which she insisted was the biggest she’d ever seen, and, above everything else, she loved me.

My side of the conversation wasn’t particularly different. I told her I hadn’t expected to enjoy the experience nearly as much as I had, that she was incredibly beautiful, that she’d done an amazing job, and that she meant the world to me.

Once we’d established that we were basically on the same page, Marketa laughed.

“Obviously, this stays between us.”

“Obviously.”

We both laughed again.

After talking for a little longer, we drove into town and went out for dinner together, just like we normally would as brother and sister. We joked around, had a great time, and eventually said goodbye with a huge hug.

I genuinely hadn’t expected going for a drive with my twin sister to be such an intense and enjoyable experience for both of us.

Next time, though, I want things to be the other way around. I want to give her all the pleasure she gave me. This weekend won’t work, but I’m going to ask her to meet me next week so I can put my head between her legs and try to make her come as many times as I possibly can.
