[if you want, school noises in background, maybe lockers closing, side chatter etc.]

[irritated] Brother! There you are! What's been taking you so long? I've been waiting here for more than an hour!

Seriously, your anime club JUST got out? What the hell do you even do in there?

[sarcastic] Watch anime? Wow, I never would have guessed! I'm not stupid, brother. I was asking why it was taking so damn long today! Don't tell me you were talking to that girl again.

Oh give me a break. She's not even that cute! She's probably already been fucked by half the guys in the club anyway. You can do so much better than her, you know. A fake, desperate slut like her isn't worth your time at all.

[Sighs] Whatever, just follow me. Yes, I know that's not the way home. I have something else I have to take care of first.

Yes, you're coming too; there'd be no point if you didn't come as well. Now, are you really going to argue with me after you already made me wait so long?

[smug/fake sweet] That's what I thought. Follow me then, dear brother.

[Pause as you walk away. Chatter and other noises die down.]

Here we are.

[sarcastic] Huh? Wow, yes, it IS a storage closet! You're SO observant, dear brother! I'm shocked that my twin of all people could possibly be such a fucking genius. Shut up and get in. [Yanks him in.]

There, that's better. No one around now. And, now to lock it... There. No one to disturb us anymore. Hm? Where did I get this key? I stole it. Duh.

[demanding] Now shut up and get those pants off.

What am I doing?

[sigh] You're seriously asking that? You totally forgot, didn't you?

Let me take out my phone and jog that brilliant memory of yours. Let's see... Yeah, here's the text conversation.

[over the top horny tone] "I'm feeling sooo horny, brother." Remember that? When I texted you during history? And your response was, I quote "I'm going to ride you so fucking hard when we get home."

And comprehension dawns. Amazing! And to think, you left your poor, horny, lonely sister waiting for so long while you were chatting up some slut using a club to get desperate guys to fuck her.

What's that? You're sorry? You're "sorry" that you made your sister wait for more than an hour? You're sorry that you broke your promise to me? Is that what you're sorry for?

Hm, it looks like you really mean it, don't you? Well, sorry isn't enough, brother. You're going to have to make it up to me, somehow.

How? Oh, I'm sure I can think of something, but that can wait. For now, hurry up and pull your pants down. It looks like I need to remind you just who owns that cock of yours.

[pause while he takes his pants off]

Ah, that's better.

[teasing] Hey, you're already getting hard for me. I haven't even done anything yet! Does being locked in a storage closet with your twin sister have you that excited?

Or maybe you're just getting excited to see me kneeling down in front of you again. I know how much you love that. [giggles] Aw, you're even twitching when I pet you. So cute... [kisses his dick]

[a few more teasing kisses/licks, getting more intense as time goes on]

Ah... Ah, fuck, I was going to tease you more, but I just can't wait anymore. I need it, brother. I need your cock in my mouth...

[blowjob commences]

[blowjob noises continue in between your words] You're so big and hard for me... I knew you wanted this as much as I did. And I'm the only one who gives you this. Other girls couldn't suck you the way I can... No stupid anime club bitch could give this to you... You'll never, ever find anyone who can suck your cock the way I can. That's why I own you. I own your cock. Isn't that right, brother? Go on, say it.

You have to say it. I won't suck your cock any more until you tell me who owns it.

Yeah, good boy. I'll give you a nice, long suck for that.

[blowjob resumes, faster now]

You're twitching so much... [moans] And your hips are bucking so hard. Just like that, brother. Fuck my mouth. I own your cock, so give me what I need! I need you! I need your cum! Give it to me! Give it to me! Fill my slutty mouth up all the way!

[blowjob noises until he cums]

[swallows] Ah... so delicious... I just can't get enough of your thick, creamy cum, brother. [licks his cock] I'll clean it all up...

[licking continues]

Hehehe, you should see your face right now. Did getting sucked off by your twin sister feel that good? It did? [giggles] I knew it would. Now then, time for round 2.

Huh? No, of course we're not done! I'm just getting started. Having your cock in my mouth isn't nearly enough, not when my pussy is so wet and ready for it. [giggles] Did that get you excited for more? Your cock certainly looks like it's recovering nicely. In that case, I'll just slip my panties off... And lean against the wall.

That's right, brother, you're going to fuck me from behind, right up against the wall of this snug little closet.

[incredulous] "What if people hear us"? You're asking that now? After you were already moaning so much while fucking my mouth?

[dominant] You don't get to ask that, brother. So just shut up and fuck me!

Oh! Wow, you're sliding in so easily. [moans] Oh yeah, just like that, push all the way inside me. [more moans] Doesn't my pussy feel good, brother? So hot and tight and wet for you? Oh...

Well, are you just going to stand there, or are you going to- OH! [moaning and sex sounds]

[suddenly scared] B-brother, you're being...so rough...

[sex noises and moaning, starting soft and turning desperate]

Oh god this is so wrong. Getting fucked by my twin brother in the school closet is so fucking wrong... But it's so fucking hot!

Oh, oh god yes! Right there! Oh fuck!

"Be quiet"? I can't! I can't be quiet when you're pounding me like this! [moans loudly] If you don't want me to scream, then choke me! [muffled as he covers your mouth] Don't just cover my mouth you fucking tease! Choke me for real! Ugh, fine, have it your way. But if we get caught, it's your fault!

[muffled moans and sex continue]

[muffled] Oh fuck, it's so good! You're going so deep into me! [moans]

Fuck me, brother! Fuck your horny slut of a sister! [moans] Take me! Claim me! Own me!

[moans and sex, getting a bit louder]

You own me, brother! You own my pussy! So fuck it! Fuck it as hard as you can! [louder moans] Fuck me just like that!

[Loud sex and moaning]

Oh, I'm getting close! I'm getting so fucking close!

Cum in me, brother! Cum right in your sister's needy pussy! I don't care that it's wrong! I fucking need it!

Oh, oh yeah! Fuck! Oh... Oh! OH!

[both orgasm]

Oh god yes! You're cumming inside me! Fill me up! Fill me up all the way! Oh!

[desperate, starting loud then getting quieter] It's so good! It's so good! It's so good... Oh, brother...oh brother...oh brother...

[pause while panting]

Ah...ah... Yeah, I'm ok.

Just...just give me a second. You've never fucked me that hard before.

Huh? No, don't be sorry! It was so, so good. I just...need a second to rest.

Hold me, brother. Hold me close.

Mmm... You're so warm... I love it when you hold me like this. I love everything you do. You love me too, right?

That makes me so happy, brother. Mmm... Kiss me.

[kisses]

[deep happy sigh] You're so good to me, brother. You always make me feel so good. It's good for you too, right?

Of course it is. Because we're meant to be together. We belong together. We've always been together, and we always will be. Us and no one else. You're all I need...and I'm all you need too.

So there's no need for you to talk to other girls, right? You have me, so there's no reason to want anyone else. Any time you want a soft, wet mouth to suck you, or a tight, hot pussy to fuck, you can have mine. Because I'm yours, brother. I'm all yours, so you can do anything and everything you want to me.

Ah, I guess we should probably get going, huh? Let me just get my panties and shorts back on...and then I'll go first and make sure the coast is clear, then head to the bathroom to clean up. I'll meet you out front later, ok? And then we can head home. Mom isn't coming home until late, so we'll have all evening to ourselves when we get home. All evening to do whatever we want.

[giggles] Yeah, I'm excited too. See you in a bit, brother.
