Izuku's POV:

Some time after we went to the beach, I found out that Kacchan sneaked out once to talk to Nezu. It was apparently something to do with angels and how they were actually bothering us. Honestly I never saw an angel after the two of my classmates ever again. That also meant that Kachan or Lamech was actually doing their job pretty darn well.

Me: Kacchan~

Today was a day where we were laying around in bed. I was just soo happy to know that Kacchan was forever at my side but there was one thing I wanted to confirm. It was very important to me since the lifespan of a human being was really short and I wanted to stick with Kacchan for eternity. Besides this was my solution for the whole angel and demon problem. Not as if I was not trusting Nezu to handle this at all.

Me: Hey Kacchan! Come on, wake up!

Kacchan: Mmmh, Zuku it's four in the morning.

Me: I know but I have a question. It's really really important.

Kacchan: What's up freckles?

Me: Is there a way for me to... well instead of being a human be a demon like you?

I must have really scared Kacchan up because all of the sudden he sat up and looked at me with such a stern face as well as a worried expression.

Kacchan: Ahm, yes but I don't think we're ready for that yet...

Me: But Kacchan... You are young and you will probably stay like this cause we have different lifespans and there is me who just grows older and older with each passing day... I don't want to lose you because of time. I want to be with you forever.

Kacchan: I know love, but... that way will keep you this age forever, I want you to look atleast 20 forever.

Me: Pff... look at yourself! You look my age.

Kacchan: Agh! Fine, but don't say I didn't warn you.

Me: Well you didn't tell me how anyways. So come on, spill it out!

Kacchan: We're gonna have to call in sick all week if we do it...

Me: What has that got to do with this?

I may be a bit innocent but I couldn't for the love of god and Satan figure out what Kacchan meant at all.

Kacchan: Izuku, you have to have... my DNA in you constantly for a week... to be able to...*blushes like a sinner in church*

Me: .... Sooo you wanna make me a blood sucker or you mean something else?

Kacchan: Izuku, there's another one too y'know.

Me: And I have absolutely no clue what you mean.

I could see Kacchan blush soo much and he also seemed a bit reluctant to tell me what he meant but honestly there were more than a million way for me to have his DNA. He could mean like swallow a hair a day like All Might transformed his quirk to me. Then he could mean something like blood sucking or tears or sweat or who knows what he meant. He is a goddamn demon. It wouldn't surprise me if he just had scales and would tell me to eat that shit or had to actually put it underneath my skin.

Me: Look I can come up with a million ways to do that.

Kacchan: It's easier for demons to turn their lovers like them if they...

Me: They what?

Kacchan: Izuku, I have to fuck you constantly for a week to turn you into a demon!

Alright... not gonna lie this was something I didn't expect that at all and hence froze up for a second looking at Kacchan bewildered.

Me: ... you know that the human body like male one isn't made to have your DNA as you said it in us for long... how do you expect me to do that?! Besides how do you even expect me to last this long?! You gonna go haywire on me for sure.

He did looked like a damn wolf in sheep's clothes right now. Don't get me wrong I soo wanted to be a demon and I wanted to be the same age as him. This was the only reason why I suggested turning me soon since we looked like the same age and I did some research online and in old, very old books saying once demons turn like 16 they won't age anymore.

Now here I had Kacchan in front of me who looked like that and here I was with the same age. Of course I wanted him to turn me but I would lie if I said I would be scared.

Kacchan: What you thinking about?

Me: .... Will you go easy one me?

Kacchan: I can't promise that.

Me: ... well thanks for nothing...

Kacchan: HAhahah.

Me: Don't need to laugh this much as well....

Do I really wanna do this?

I am sick of actually getting Kacchan in trouble and what if he dies because of me?!

We would be safe in hell at least I think.

Me: *sigh* Let's do it.

Kacchan: Are you sure Izuku? It's gonna hurt.

Me: I am sure about it... you should probably book the nicest suite in hell...

I didn't care at this point how hard it would be on me or if it would hurt at all. I was scared about it but if that meant being with Kacchan for eternity then I was soo ready for it.

As he promised me, we waited for another week since he had to kinda get the approval of both. Nezu and Lucifer. Turns out Nezu was in charge of all the demons on earth secretly and Lucifer the one in charge of hell. Anyways long story short, we got their approval and they kinda also booked a love hotel room for us.

This was just the beginning of our 7 day long trip of pleasure and sometimes even pain since my dear Kacchan was definitely too big and to thick for me. If he didn't butter me up first then it was a hell ride for me but pleasure for himself. Let's also say that I made it hell for him whenever he did that cause I found out that the tip of his tail was rather sensitive and paid him back tenfold.

All in all, it was soo wroth it and with a demon body, I could definitely say I would also pay Kacchan back for the 7 days now that I had time till eternity and more for this.

Me: Kacchan... thanks and I love you.. You know that, right?

Kacchan: I know freckles, now, what's next?

Me: Your personal 7 days of pleasure!
