You ready for some serious brain work, Jimmy?

Uh, I guess so.

Are you sure about this?

You did ask for my help, didn't you?

Alright, let's just start with the basics.

Differentiation, ever heard of it?

Alright.

It's just the basic mathematic operation of finding the differential and

deviation of a function.

Check out this example.

I just don't get this.

It's like some alien language or something.

Alien language?

This isn't some sci -fi, Jimmy.

It's so complicated.

If you compare graph A with the sum of example B, D, and E, then you'll see the

pattern. Do you see it?

No yawning, Jimmy. We have a long night ahead of us. Oh, uh... Yeah, uh...

What... What's the pattern?

Okay, look.

I'll just write it down for you, and you can look at the formula, alright?

I can't do this because this is too much.

Look, maybe you just need a snack or a drink of water.

Look,

Jimmy, you can do this.

I just have to figure out a way for you to understand it, and then you'll be

better than I ever was.

Maybe I just need to face facts, then I'm going to cut out for this.

It's okay to struggle, Jimmy, but we're not a family of quitters.

I'm not a quitter.

Okay.

Look, I think we need to take a break. I'm gonna go splash some water on my

face. Yeah, I'll go make some coffee.

Oh, my God.

Back to me.

I'm happy to help. It's not easy material.

I really don't know what I'd do without you, honestly.

Look, it's the least I can do, bro.

No,

but for real, I'll take the time.

Like, even if you were my step -sister, you know, most people wouldn't.

Well, if you fail, you make us all look bad.

Why you, no way! Why you gonna put all that pressure on me like that?

Ew. I'm sorry.

I'm sorry. I'm just teasing you.

No, I forgot, though. It's getting really late. I think we should go finish

You're right.

Let's go.

Yes.

Yes, Jimmy, yes.

Wait. It's making sense now.

See, I knew you could do it.

All right, now we're in the final stretch. Check out this problem.

This one's a tough nut to crack.

It's like we're back at square one again.

Maybe we should take another break.

We're almost done.

No, no, you're right. Let's go.

I'll tell you what.

Just lay your head down for a minute.

I won't let you go to sleep. I promise.

Okay. Just a few minutes.

Oh, I got it.

Good job.

Love you, bro.

Love you too, dude.

Come on, let's wrap this up. Let's go to bed.

I'm tired.

Look, I got a 90 on my test.

Oh, my gosh, Jimmy. You've come such a long way.

I know. Thanks to you, though.

Thank you so much for helping me. I mean, it wasn't just me.

You put in the hard work.

I mean, I even fell asleep in the last half, and you powered through those

concepts all on your own. I did, didn't I?

You did.

You're a freaking rock star.

What? What's that look?

Nothing. I just had so much fun studying with you last month.

So I wasn't too much of a tyrant?

No, not at all.

A little sweet, even.

Really? Because it kind of seemed like you wanted to rip my head off.

I did, for sure.

But in the end, it was totally worth it.

Well, if you ever need to study, buddy.

I'll be sure to ask.

You know, I actually don't remember how I got to bed last night.

Yeah, you fell asleep on the desk back there.

Oh my gosh.

No, it's alright. I helped you to bed.

Well, I just hope I didn't say anything stupid.

I do that sometimes when I'm in a sleepy fog.

Like what?

Uh, you know what?

Never mind.

Look,

I got 110 on my test.

I got a perfect score, and I got the bonus question right. Oh, my gosh,

I'm so proud of you.

You know, now that you got the hang of it, maybe you'll have to start teaching

me.

I don't know. I like it better when you're in charge.

Do you think we've gotten a little closer?

Uh, yeah.

Sure.

Don't you think we should do something other than a semester to celebrate?

Like what?

I mean, I don't know.

Well, I mean, I don't think we should celebrate before we actually finish the

semester, you know? It's kind of like bad luck.

Yeah, but I mean, isn't it important to celebrate the little wins?

Not if it gets you distracted.

You gotta blow off some steam somehow, though.

Yeah, I guess.

Hmm.

How do you unwind?

I mean, I guess I sometimes go for a run.

Well, when I get a little tense, I just redirect my attention to masturbation.

Jesus Christ, Jimmy.

What? Why did you tell me that?

I mean, what? It's true.

Okay.

God, you're such a boy.

Okay, and is that a problem?

No, not at all. I just didn't think we were that close.

Like all these endless nights we've been studying.

I spend more time with you than I do my girlfriend.

Yeah, I mean, I guess that's true, but don't go around telling people that.

They'll get the wrong impression.

That's okay. I'll keep your secret.

What do you mean?

Oh, nothing.

What secret?

Well, last night you kinda told me to kiss you.

Oh my god, no I did not.

But maybe you meant it as a brother.

Ugh, right.

But, you did tell me you loved me as well.

Ugh, kill me now.

I mean, you know, it might have been a dream, something you were dreaming

I am so sorry.

Okay.

No, it's not okay.

You have a girlfriend, and she'll be furious.

I mean, it's even worse that I'm your stepsister.

It's okay. I thought it was... No, I'm humiliated. I can't. I just can't.

No, no, look. Chill, chill, chill.

You're going to wake up Mom and Dad.

you if you want me to.

No, it's just... There's nothing to explain.

No, but I feel like there is.

Okay, I'm listening.

Okay, well, I like you.

Like, like you.

Yeah, well, I like you too.

No, stupid.

I have feelings for you.

Oh.

Yeah, and it's okay. You don't have to feel the same way.

No, I do. I really like you too. I like you a lot.

You don't have to say that just to make me feel better. I can just pretend that

we never...

Why?

Because I wanted to.

You don't have to appease me.

I mean, if I knew you had a crush on me, I would have totally joked about the

masturbation thing.

Okay,

well, on that topic.

I have a confession.

Oh, yeah?

Hit me.

Well, during some of our sessions, I would sometimes, you know,

sneak off to my room and come.

I had no idea.

You seriously didn't understand when I would come back to work suddenly

No, I never put you and two together.

Well?

Thinking about me?

Yeah? Mm -hmm.

Can I... Can I see it?

Yeah.

Just stroke it.

I want you to squeeze it.

I like seeing the little veins bulge.

I want you to take my clothes

off.

Yeah? Yeah, I want you to see my breath.

You know, you're not done taking my clothes off.

Can I see it?

You like the way it tastes don't you?

My sister's pussy tastes like that.

Yes, just like that.

I don't know, my brother is so good at eating puffy.

I never knew my sister masturbated so much.

Yes, right on my clit. That's gonna make me fucking cum.

Yes, that's gonna make me cum.

Yes.

Fuck yeah.

Oh my god.

Oh my god, yes.

Oh, fuck.

so I can show you what my mouth can do. Yeah.

Oh, come here.

Yeah, like your brothers are taking your mouth.

Fuck.

Yes.

Fuck.

Oh, my God.

You're like throwing my mouth at you.

My brother is such a big cuck.

Oh, fuck. Oh, fuck.

I don't know how much I fantasized about this.

Oh shit.

You

think

this mouth is good?

I'm afraid to put on tape.

Yes.

God, that cut feels...

this fucking shirt off.

Oh, it's not fair. I'm the only naked one out here.

Just like, just switch my typos, you know?

Fuck.

Fuck,

yes.

Yes, just like that.

Oh, my

God.

Oh, shit.

Yes, fuck.

Oh, my God.

It's stretching me out.

I'm going to go nice and slow so I can pull every inch.

Yes.

Oh, my God. Yes. Just like that. Fuck.

Oh, fuck. That's going to make me want to eat them.

Yes. Don't. Please stop.

Oh my god, yes, yes.

Yes.

Keep going, fuck. Just like that.

Just like that, yes, yes.

Oh, shit.

Oh, fuck.

Fuck, yes, I'm coming.

Oh my god, I'm fucking coming.

Oh, fuck.

You know what, babe?

Yes.

I want every last drop of my brother's cup.

Yes, give it to me. Give it to me.

Yes, come for me.

Yes, come for me.

This is so fucking good.

Oh, my God, yeah, you like when I play with my pussy while you fuck me?

Oh, fuck.

Oh, fuck, yes, yes, yes.

Oh, shit.

Oh, fuck.

Oh, my God.

Yeah, fuck, you like doing all the work.

fucking make me take it.

Oh my god, yes, just take that.

Yes, just take that. Fuck, I want to come all over your cock again.

Yes, please make me come all over that fucking cock.

Oh my God.

get dressed and get back to studying before mom and dad find out.

Yeah, you're right.

Come on, let's get cleaned up.
