I'm riding my big brother in the backseat with my mom and dad right in front of me. And they don't even notice.

Part 2

Hey! Sorry, I know I'm making us a bit late but somebody didn't bother helping me bring my stuff down.

What?

Mom, what do you mean we don't have space? I need everything in here. Look at how much space bro's taken up.

Just because he got here first. Well he wouldn't have gotten here first if it wasn't for me. He left me up there all alone and frustrated.

I just mean he wouldn't have even finished packing if he didn't have my help.

Wait, here's an idea. What about I just leave my stuff in the backseat with us? I can just sit on bro's lap.

Come on, I really do need everything. Dad?

Not you too. I'm serious though. Big bro, tell them.

<whisper> You owe me after what you just did asshole.

<normal voice> See, so can I keep all of it?

Great! Bro, help me put all of this in the car. Come on, hurry up.

<sound effects or improv>

There! No problem. Now get in the car.

Yeah, and I can just squeeze in like this. Aaaaaand, perfect. You comfortable big brother?

<whisper> You like having your little sister sit on your lap? I am so getting you back for leaving me hanging up there.

<normal voice> Yep, we're all ready to go Mom. Lets get this road trip started!

<whisper> I can already feel your boner pressing against my ass through my skirt. You've been this hard the entire time haven't you. That's why you were so okay with me sitting on your lap like this huh? Cause you wanted to feel my ass against you for this trip. Well I doubt mom and dad will notice if I adjust myself a little. Just lift the back of my skirt up a bit and...there. Now your cock is pressing against my ass. You picked a bad day to wear jeans didn't you.

<giggle>

<normal voice> Oh, it's nothing dad. My stupid brother is just tickling me a bit. It's so annoying.

<whisper> Did you notice? I took my panties off before I came outside. Can you feel it? My dripping wet pussy against your cock? I warned you what would happen if you got me all worked up. I still haven't cum yet but I really want to. Maybe if I just...

<giggle>

<whisper> Yeah, that seems to work. Grinding my pussy against your bulge. The denim is a bit rough but I can handle it. I'm way too horny to stop now. Even in the same car as mom and dad, I can't help myself. You love it though, don't you? I can feel your cock twitching inside your pants. I bet you wish you could throw me down and fuck me right now. The funny thing is, I don't even know if I would stop you. You've turned your little sister into such a slut. I would do anything to get off right now.

<zip sound effect>

<whisper to normal voice>
Um, hey. What was that? What are you...oh.

Uh, it's nothing dad. I told you, he just keeps being annoying.

Cut that out bro. It's gonna a long trip.

<whisper> You pulled out your cock? Seriously?

I was just teasing you, I didn't think that you were actually gonna do that you sick perv.

I mean, yeah. I am really horny.

And yeah. It is nice feeling your cock against my ass.

Um, here.

How does it feel against my pussy?

<quiet moans between or during dialogue>

Fuck, that's nice. This is so dirty. Mom and dad are right there. You're making me so fucking wet. I can barely control myself. Fuck, I can't take it.

I need you inside of me. Right now.

Yes, I'm serious. Just, don't move. Or else they'll notice. Just let me do this.

Not. A fucking. Sound.

<almost silent moan as cock enters>

Oh my god. Oh my god. Oh my god.

This is insane. I'm riding my big brother in the backseat with my mom and dad right in front of me. And they don't even notice. This is so fucking hot.

No, you can't move or else they'll notice.

Fuck. Why don't you ever listen to me?

If your cock wasn't so big, we wouldn't be able to make such small movements. This is crazy.

<louder sharp moan>

<normal voice> It was just the speed bump. It surprised me. You should really slow down when going over them mom.

<whisper> We're so close to getting caught. If we're just a little too loud or a move a little too much, they'll know. Fuck, if they turn around and get a good look at us, they'll know. Mom and dad will know how dirty their kids are.

They'd see their son is a dirty pervert. So bad that he'd take advantage of his own innocent little sister.

Then they'd see me. Their little girl. Just a slut for her big brother's cock.

I wouldn't even stop if they did. I'm too close. And there's no way you're denying me of my orgasm this time.

I need to cum big brother. Right now, I need it. So let me ride you. Let me ride you with my tight little cunt.

<quiet moans and improv to orgasm>

Finally. Fuck, that was so hot.

You're almost there aren't you? You want to cum? You have to cum inside me. There's nowhere else to do it without getting caught. I know we've never done it before but we don't have a choice.

So come on. Fuck me. Unlike you, I'll actually let you finish. Just be quiet about it.

<quiet moans>

Fuck, that feels nice.

You should cum in me more often.

<giggle>

<normal voice> Hey dad, how long until we get there?

Six hours?

Well I guess we'll be stuck like this for quite a while bro.

<whisper> For once, this might actually be the fun part of the trip.

<giggle>
