Man, I really gotta study this or I'm gonna fail this class.

What does the male reproductive system do?

This is so hard.

I'm gonna skip that one.

What is semen and what does it look like?

What kind of question is this?

Too hard.

We're three part of a penis.

I mean, dick and balls, what the fuck?

How am I supposed to learn all this?

I need a real life example.

And the only one available is my stepbrother.

Ew.

If I don't do it, I'm going to fail.

I better go ask him.

Whoa.

Hey. Sis, what are you doing in my room?

I need help studying.

Well, I kind of need some alone time right now. Do you think you could just,

don't know, leave my room?

No, I really need to help studying.

And... Seems like you're already hard, so I think this is the perfect time.

Oh, come on. Stop it.

Well, this right here... Will you just leave me alone?

I can't. I really gotta study.

I mean, you don't find it weird at all that you're trying to use your brother's

cock to study?

I mean, it's just for, like, work purposes, right?

I mean, I guess if you want to use my cock for your diagram, you can.

Sweet.

Now these are the testes.

They also make and release sperm cells.

And then right through here is the urethra, which

carries semen out of your cock.

And then the prostate gland, which is right here.

substances that protect and nourish the sperm cells and then right here we got

cock glands and all that what else we got here

and then like right down below we got the scrotum which carries all the nut

well yeah i guess that seems like a lot of information to learn yeah it's a lot

to learn

You know my penis is just going to stay hard if you keep touching it like that.

I mean, it'll help me pass my test, right?

I mean,

it does feel really good.

I guess it works out for both of us then.

Are there any techniques in that book?

Oh, yeah. It says right here that if I do this correctly, I can make your cock

ejaculate. So, I kind of want to try that out.

Wait, what? Are you serious?

I mean, it'll help me pass my test, right?

I mean, I don't know. I guess you could try.

Sweet.

master at male anatomy after this class, sis. I hope so.

I'm taking all this time to do my research.

I feel the glands on my tongue.

Faster when I stroke and suck at the same time.

It feels so much better when you're stroking and sucking.

You really know what you're doing.

Well,

you're helping me get an A.

Mmm.

I'm gonna puff my -

Looks like my job here is done.

Thank you.

Guess what?

What? I got an A on my exam.

Oh, no way. That's awesome. I'm so excited for you.

Oh, yeah.

Also, I need you to help me with male reproduction and ejaculation.

Oh, what? You couldn't get enough, could you?

You're just my brother. That's weird.

I'm trying to be a nerd.

I think you're just obsessed with your brother's cock.

No, I'm just trying to be a nurse.

And then, um, I need to record your sperm count, and I thought you'd be,

the best to help me with that.

I'm kind of busy. Don't you think you could bug someone else? I don't have

anyone else right now. Please, I'll do anything.

I guess if you're trying to do something for me, but I don't...

I don't know what it is yet, so I'll let you know later.

All right, that works. Let's get this going.

I'm going to set up my film report then.

All right, come over here.

Alright, thumbs it over here.

By stimulating his thighs with wine, this should help to build up his sperm

count.

How does that hand feel around your cock?

Like how your sister rubs her pussy against the cock like that.

Oh, fuck.

Oh, yeah.

Oh, fuck.

Oh, shit.

Oh,

yeah, I've built up that sperm.

Yeah.

Oh yeah.

I can feel your calves throbbing.

Keep that hand on me.

Shit, I hear mom's keys.

Get the clothes.

Hurry.

Sis, what are you doing under there?

Will you get out from under the covers, please?

Why?

This outfit is embarrassing.

What the fuck? Who cares?

You got a good grade because of me. You owe me, remember?

I mean, yeah, but this is kind of like mocking my career.

Oh, come on. Just put your arms down for me. Maybe do a sexy little turn.

Just show that outfit off for me, okay?

Okay, I guess you're right.

I do owe you.

God, you're so hot and sexy in this nurse's outfit.

I'm your sister.

So?

I've been fantasizing about this day for a long time.

What? Yeah.

Seriously? Of course I have. I mean, how could I not?

You're so hot in that outfit.

Oh, damn.

Um, what do you say you come lay over here?

I'm trying to get some stimulation first remember?

I see.

the rest of that outfit off.

You want this cock in my mouth?

Yes, yes.

You're just like teasing me, don't you?

Yeah, just like how you teased me earlier.

You love how your sister slobbers on your cock.

Only you know how to make me cum so good, sis.

You want your brother's cock inside of you now?

I want this cock in me so bad.

I'm ready for you, sis.

You can have it.

It's gripping it so, so bad.

finally happening.

Never in my life did I think I'd be fucking my brother all because I passed

exam.

Yeah, fucking sexist pussy.

Oh my god, yeah.

Oh my god, I love

how I grip it.

I bet you have a nice buildup that you're ready to nut load on my face.

I mean, you've been overstimulating me for a while now.

I know.

I have so much time for you. Yeah, I want all that buildup on my face and

and mouth.

Oh, my God.

Please don't let me come, like, really quick right before you build up on my

face.

Put that buildin' fuckin' load on my face. Yeah.

Well, if you ever need help with your studies in the future, you know the

Yeah, that's a good idea.
