Original subtitles

This is my last week here.

I need to cum right now though...

The new nurse is.

Yamada!

What?

So big!

How you doing?

Where's that voice coming from?

Hi there!

I'm the hospital's investigator, Amamiya.

I'm her assistant, Otsuka.

Otsuka, get naked!

Shit!

I forgot you aren't used to dicks!

Remember your training days and squeeze that dick!

Do it properly! No shame!

That's too hard!

Otsuka, be more gentle or you'll rip it off!

I'm not applying any force.

Do it properly! I need him to give away some healthy sperm!

I've got an idea! Otsuka, use your mouth!

Like this?

Um...

That's right, now sit on his face!

Sure!

Now do the rest with your mouth!

Come on! Let's go! Otsuka!

Cumming!

Let's see, now this!

Now put that semen in this jar!

Don't swallow it! We need that for our tests!

Sorry...

Jeez! Can't be helped!

I'll do it myself!

Lucky you!

Yamada! Be sure to enjoy it!

Does it feel good?

My dick is rubbing against her stocking.

Cum whenever you want!

It's twitching.

Nice! I'll use later, so make sure to cum a lot!

Sorry, but this isn't enough to make me cum.

What!?

Otsuka, do your thing!

Right away!

How you dare to say that!

Take this!

Yamada...

Wait, you're sucking too much.

That's good! He's getting bigger!

Amamiya...

What's wrong, Otsuka?

I'm starting to feel good, what should I do?

It's fine! Just cum!

Otsuka! This is amazing!

He's feeling it!

I'm cumming!

Otsuka, let's go!

Cumming!

As expected from Otsuka, nice job!

Sure!

We got 500mL.

It's full to the top.

Amazing!

That's more than what we expected!

Nice! Time to do lab tests!

Sure!

It's finally over.

But why would they want to investigate my sperm?

What!?

It's easy to know who's coming.

Yamada!

I have good news!

What?

While examining your sperm, I've discovered an unknown strange disease!.

A strange disease?

So now I'll take you to my lab!

So we can observe you with great detail!

Otsuka!

Wait!

Time to work!

Out of my way!

Yamada?

Look at this, Otsuka!

Look!

His sperm multiplies at an incredible speed!

It will go down in history as the Amamiya-Yamada disease..

What about me?

Wait! You're part of this too!

What about...

We'll call it the Amamiya-Otsuka-Yamada

Nice! It's settled then!

You can't do this without my consent.

Oh I can.

Look.

Do you remember this?

What?

Hereby, I give authorization for within the hospital...

I grant full use of my body for experimentation and analysis, as determined by the staff.

Yamada.

See?

I did it for you!

No way that's legal!

Seems like you're ready!

Time to milk you out!

Otsuka, get naked and have sex with him.

Do your thing!

Right away!

You don't have to do this..

I'm the best at my job!

Eh?

This time we'll scan the flow of your internal fluids.

Yamada, here I go.

It's in.

So tight!

It's going in.

Otsuka, it's having a hard time to break in!

That's because it's my first time.

Otsuka.

Otsuka, have fun!

You're doing great!

Otsuka, move your hips up and down!

This feels... good

Is this sex?

My tummy feels weird.

Nice! Just like that!

You're doing great!

I'll do better!

Look at this!

Yamada's balls take turns to generate sperm.

He can alternate between them.

This is great! Make him cum!

Cumming!

Otsuka, I'll shoot it inside!

Otsuka, remember we need that sperm!

Otsuka, wait!

Right here!

So hot! But it's not enough.

Otsuka, one more time!

Sorry, I need some time.

Otsuka!

Alright!

My turn then!

I can't do it that much.

Yamada, I can tell your balls have already generated that sperm back!.

Don't worry!

It's my turn to make you cum!

Otsuka, prepare the next jar.

Sure!

Yamada! Let it all out!

How's this, Yamada!?

You're too noisy, I can't focus.

Sorry, it's been a while and I got a bit too excited.

My voice is too loud.

But I do this is in the name of science.

I'll squeeze it out.

I want you to let everything out.

I'm your patient.

It looks like you just wanted to have sex...

That's not it!

I do this for my research!

But you are feeling it..

That's true, but...

It's part of the testing.

Professor, that angle is teasing my tip

Professor, his balls are fully charged.

He's about to explode

That's good to hear.

Cum as much as you want!

Professor, I'm cumming!

It's coming in...

The sperm is ready to be collected.

I wouldn't mind to keep going, but..

Otsuka! Bring the jar!

Professor, whenever you're ready!

Otsuka.

Here comes a big one!

Amazing!

Just one more time.

It's full.

Otsuka, let's put it in the data analyzer.

Sure!

Let's how this goes!

The result is mixed with your fluids..

We can observe his sperm moving at a high speed due to the arousal .

That's nice!

We can't stop here!

Yamada, one more time!

I can't...

What you say?

Otsuka, it's time to use the AAG!

Sure!

What?

AAG! Amamiya Aphrodisiac Gas!

Smell this, and you'll get your virility back in a second!

Give it a good sniff!

Otsuka, keep it coming!

It seems like I smelled it too...

My womb is feeling weird..

I want to have sex!

I haven't tested the gas effects on women yet!

Can't be helped, safety is first.

Otsuka, stop the gas.

It seems like we already ran out of it.

Yamada, it's Otsuka's turn!

I just want to fuck the pussy in front of me!

Wait.

Professor, that's not fair.

It's not what you think, Otsuka.

It's my turn.

Your pussy is so tight, it feels so good!

I may have sniffed some of that gas too.

I love it rough!

I love it deep.

I can feel your underwear rubbing against my dick, it's so good!.

I like it too!. Keep thrusting me!

This angle is so good!

I don't care about the test anymore!

Professor, get yourself together, we have work to do!

We need that sperm!

That's right, I almost forgot about it.

It's just this feels so good...

I love it.

Cumming!

Yes! Cum inside me!

Give me all of it!

Cumming!

It's twitching.

So good.

Professor, the test!

That's right!

Yamada, don't pull it out!

Otsuka, get ready!

Do it slowly.

It is so much.

Now that you have it..

It's your turn.

I'm sorry, Otsuka.

I can't hold back anymore.

Don't worry.

I was just a bit surprised.

Put it in.

It's all because of that gas!

Yamada, you're getting bigger than before!

Keep fucking me as hard as you want!

So deep!

Right there!

Otsuka, you're so wet and sexy.

That's because of the gas.

Yamada, this position is a bit embarrassing.

Otsuka, show me your face.

Like this?

Otsuka, you're so cute.

What are you saying?

You're getting tighter.

I'm about to cum.

Do it! Shoot it inside me!

Cumming!

I can feel it going inside me.

Don't pull it out yet, the jar isn't ready.

We'll do it again then.

Let me see as it goes in and out.

I knew sex was good.

But it's a bit embarrassing.

What are you saying while having your pussy full of semen?

Don't say that.

Otsuka, you're so strong and cute.

I'm not like that.

It feels good.

I think I love sex now.

What are you doing? Having lovey-dovey sex as if you were lovers!

Otsuka, hurry up and squeeze it all out!

That's right, I can't forget about my job!

But it feels so good.

Otsuka, right now I think it's more important to have fun while having sex..

Otsuka, make sure to hold him tight!

Sure!

Yamada, it's time!

Let it out!

Otsuka, amazing...

Your tits are so huge I can't breathe.

Enough talk, hurry up and cum!

You're so tight inside!

Don't suck my tits!

It's overflowing.

We're wasting the test materials.

So good!

My whole body is throbbing.

No!

I'm cumming!

Yamada, please don't pull it out.

I'll get the jar ready

I can't...

Wait!

I can't hold it in.

It's coming out!

His sperm won't stop coming out.

It's going in directly.

It won't stop.

Don't worry! Let it out!

My computer isn't going to break down because of something like this..

It looks if I was the one cumming, it feels good.

Professor, it broke down.

Don't worry about it!

Girls, thanks for everything.

Um...

Tachibana.

We're really busy because of yesterday's blackout.

I couldn't care less about your discharge, don't get in the way..

Um, I just wanted to thank you.

From now on, you can jerk off with your own hands.

You're so stupid.

Yamada!

Today's your discharge, right?

Be careful!

I missed!

I can feel a great thirst for blood.

Yamada.

Congratulations!

Otsuka.

Thank you so much.

Otsuka, nice job!

I've had enough of your bullshit!

Tachibana.

I hate to do this

But apparently, there's something unusual about your sperm..

It seems we'll continue taking care of you.

And now they're asking us to collect your semen without any female fluids..

There's no one like you, Tachibana.

Quit saying such gross stuff.

Now...

So good!

But when will I finally be able to get out of here!?
