Making the first move on Sis

Okay, so I'm not balls-deep in Mom. YET. I'm writing from the taxi, because it's the longest ride ever and there's fuck-all else to do; our new data plan hasn't activated yet, and I don't have anything good downloaded on my phone.

I guess there's one cool thing about the ride, though: the taxi driver's a naked, modded-up woman with tits the size of beanbag chairs. Mom and Sis barely managed to hide their disgust, while me and Dad barely managed to hide our erections. I tried to ask about her bazongas, but my parents shut me down pretty quick. That's total bull, if you ask me; it's not like she's trying to hide 'em.

Now that I think about it, I'm probably allowed to do way more than just talk about her tits... I could take her for a spin. Like, fuck her. For real. But according to the rules of our new home, I'd have to ask whether her son is cool with sharing... And that would mean blowing this whole Oedipal Zone thing wide open in front of my entire family.

I could do that. I WANT to do that. But I'm too fucking nervous.

Did I mention that my sister's body is pressed up against me right now? Luckily, she's too busy with her shitty phone game to take a glance at the stuff I'm writing. I could just reach over, grab her head, and pull it to my crotch... Then five seconds from now, I'd be getting my first blowjob.

Uuuuugh, why can't I bring myself to just do it?

I did it. I did it, and I'm fucking shaking.

Okay, let me start from the beginning. My sister got bored of her game, noticed me writing, and asked what I was up to. Before I could hide the page, she saw the word "sister" and freaked out, accusing me of... Man, I don't even know what. Writing secret propaganda or whatever.

Anyway, she started needling me and I got mad enough to break through my inhibitions. I told her I was writing about what I was gonna do to her, now that we're living under new rules.

That goes EVERYONE'S attention. The whole car was silent, then everyone was talking at once... Except the driver, who just sorta smiled and gave me a wink. Sis yelled at me for lying, Dad yelled at me to explain, and Mom demanded an explanation from HIM. Apparently he was supposed to be in charge of looking this kinda stuff up, and in typical Dad fashion he never got around to it.

Once I could finally get a word in edgewise, I looked him dead in the eye and just said: "This is an Oedipal Zone, Dad. You know what that is, right?" My voice was trembling a little, but I managed to put SOME confidence into it.

He had no idea, but wasn't willing to admit it. "Of course the rules are a little different here," he said. "They're different everywhere. We'll adapt."

Neither my mom nor my sister were satisfied with that answer, of course, so they turned to me. "So, what, you're old enough to use girls here?" Sis smirked at me. "Is that why you're acting all weird?"

"Y-yeah, for starters," I muttered back quietly. "...Touch me."

"What?" I don't know if she couldn't hear me, or if she just wasn't prepared for her brother to make that kind of demand.

"Jack me off, Sis." I started fumbling with my belt as both of our parents looked on, mouths agape.

"I... Seriously, is this for real?" My sister looked around the car. Mom and Dad offered no response, but the driver nodded.

"This is an Oedipal Zone, Deary," she said cheerfully. "He may be your little brother, but he's well over the age of majority here, and he's the oldest son in your family. That makes him the boss."

Dad looked at her dumbfounded and opened his mouth to reply, but nothing came out. It was Mom who finally spoke: "Well, um... I guess you should give him a handjob, Hon. You know how, so just... Yeah."

My sister swallowed hard, then reached over to help me with my pants. They hit the floor along with my underwear, and before I knew it her slender fingers were wrapping around my cock. I reached full-on-boner-mode in two seconds flat, and while her grip was timid at first, soon she was stroking me like a pro... Which she is, I guess. She definitely got enough practice at college back home.

"Fuuuck, that feels so good," I moaned.

"Hey, no, don't do that," she snapped. "Don't be weird."

"Y-you don't get to tell me what to do," I stammered back at her, practically whispering.

"What?"

I took a deep breath, psyching myself up before trying again. "I'm in charge now, and I'll say whatever I wanna say while you're serving me."

"I--"

"Stop talking. Suck my balls."

Again, the car went silent. Again, the driver smirked. "You heard him, Deary," she chuckled. "Get to work!"

And you know what? She fucking did.

My parents looked on in horror while my sister dove in and began lapping at my ballsack. I didn't know it was possible to get any harder, but goddamn... That was the best thing I'd ever felt. Honestly, I lost control a little bit: roaring like an animal, grabbing at my sister's hair, leaning over to slap her tight butt... Mmmf.

And yeah, I fulfilled that "first blowjob" fantasy. Since our driver was so helpful breaking the ice and shit, I decided it would be rude to cum all over her upholstery. When I got close to unloading, I got Sis to suck it all down... And keep sucking after that.

That's where we're at right now, actually. She's still got my tip in her mouth, and it's pretty sensitive... So please excuse my shaky-ass handwriting.

I'm getting hard again, so I'm actually gonna get Sis to stop blowing me. We're just arriving in the suburban-ish part of Madreput, and I wanna save Nut Number Two to break in our new home... And my new relationship with Mom.
