As Y/N and Loona continued to kiss, they departed for a moment and panted. They then looked down and realized that Y/N's dick was aligned with Loona's pussy and they looked at each other.

Y/N: Shall we?

Loona: Yes. Come on, N/N! Fuck me!

Y/N: As you wish.

After getting in position, Y/N inserted his dick into Loona's pussy and they both cried out as their waists are perfectly collided as if they were perfect for each other.

Loona: Oh my God! That's new!

Y/N: Rrgh! S-So... tight... and wet... Loona... Your pussy... feels... so good...

Loona: And your dick... is so... big... and fat... i-in a good way... Oh!

Y/N then pulled out and went back into Loona's pussy. Soon, he was able to repeat the same motion over and over and as he did, Y/N gritted his teeth and Loona clenched the bedsheets as she tried to hold her moans in.

Loona: N-N/N... Please... Don't... stop...

Y/N kept up the pressure and as he did, Loona clenched her teeth as hard as she could, but she failed to hold her moans in and moaned as loud and hard as she could while Y/N amped up his speed a bit.

Loona: N/N! Please! Oh! Give me your love!

After a while, he eventually got exhausted.

Y/N: Damn... No good, huh? Sorry, Loonie. I'm all tuckered out.

Loona: Hah... Hah... Hah... N-N/N, lie down! Let me try!

Y/N: Huh? Whoa!

Loona pushed Y/N onto his back on the bed and Y/N blushes as he saw Loona in her glory again as she had Y/N's dick in her. She repositioned herself and got in the proper position to mate with him.

Loona: Okay, N/N. I'm ready. You?

Y/N: Yeah. Show me what you got.

Loona: Be careful, N/N. You may be part hellhound, but here's one thing about us. We are absolute beasts when it comes to sex. At least that's what I was told. Don't blame me if I shatter your pelvis.

She then got started on moving up and down slowly on Y/N's dick. As she did, both Y/N and Loona panted and moaned as she kept going. The sound of their flesh slapping against each other as they mate filled the bedroom and so did the heat they both were radiating from their sweat and bodies.

Y/N: Hah... Oh... Mmf... My God... L-Loonie...

Loona: That's right. Say my name, honey. It'll only fuel me up to keep going!

She continued to moan as she kept up the pressure. Her speed amped up, but she stopped to breathe for a bit. She then looked at Y/N and smirked.

Loona: Hey, N/N. Tell me something. When there were times where I was getting changed, have you ever taken the chance to take a peak at my body?

Y/N: What? No, Loonie. I'm not a pervert. I respect my roommate's privacy. I promise.

Loona: Well, that's good to hear. You're a respectable gentleman. Although, since things are gonna be different from here on out, I don't mind if you want to take a peak. That is, unless you want to go again. Hehehehe. Alright, N/N. I've had my fun. Now, it's your turn. But!

She then grabbed his neck and pulled him to her face.

Y/N: Whoa! What a woman.

Loona: Don't even think about holding back on me, N/N! I want you to release your demonic side and fuck me like a man! You hear me?

Y/N: Sure thing, Loona.

Loona: Okay.

Y/N: ... *smirks* Assuming... your dirty mind can handle it!

He then grabbed her collar and yanked her down on the bed. He then grabbed both of Loona's wrists and held them up.

Y/N: Wanna rethink this through?

Loona: Hah... Hah... Hah... No! No, N/N! I want this! No, I need this! So, come on, N/N! Fuck me like I'm your bitch!

Y/N: Your funeral.

He then smirked and slammed his dick into Loona's pussy and began mating with her. Loona gasped and cried out as Y/N kept up the pressure, but overtime, she began to smirk and her pupils dilated to hearts.

Loona: Come on, N/N! Fuck me like you love me!

Y/N: Oh? Are you pleading for more? Well, I'm afraid that you're going to have to beg for more. So, come on, Loonie. Let me hear you beg!

He then removed Loona's collar and grabbed her neck with both hands as he started choking her as he slams his dick.

Loona: Oh! Oh, fuck!

Y/N: Come on, Loonie. I know you can't resist this. If you want more, then beg!

Loona: Gah! ... P-Please...

Y/N: Please what?

Loona: ... I... I-I can't take it!

She then locked her legs around Y/N's waist and pulled him in.

Y/N: Whoa! L-Loona?

He then realized that Loona's pupils dilated to hearts and she was panting heavily like a dog and her tail was wagging crazily.

Loona: *blushes lustfully* N-N/N... I... I want you to smash your dick into my thirsty pussy and fuck me senseless! I want you to ruin my insides and fuck my dirty brat mind until I go numb! I want you to... I want... I want you to claim your ownership over my body and make me yours forever! I wanna love you forever because you make me happy! Now, please, N/N! Please, fuck me until I pass out! I want this so fucking badly!

Y/N was speechless against how badly Loona wants to mate with him. But, he was not in a position to refuse Loona's wishes.

Y/N: Q-Quite the masochist, aren't you? You really want me that badly?

Loona: *blushing lustfully* Yes... More than you know. Please... Make me yours. I want to be yours and nobody else's.

Y/N: ... Very well, then. If you're so desperate. ... And I know just how to make that happen.

He then leaned down to Loona's neck and licked her for a bit and she moaned. And then, Y/N gently sinked his teeth into Loona's neck and she continues to moan, but harder. After a while, Y/N left behind a special mark on Loona's shoulder pad.

Y/N: How's that?

Loona: Much better. But, I cannot leave you unpaid. So... Allow me to return the favor.

She sat up to Y/N's neck and began to do the same thing to him, only the mark she left behind was different. Now that both of their marks are implanted into their skin, Y/N and Loona were officially soulmates for life and death.

Loona: And now... We're forever together.

Y/N: No arguments here. Now, time for me to give you a ride.

He then started to move his dick in and out of Loona's pussy with more pressure and strength and Loona gasped and panted heavily. But, she grew a smirk, knowing that Y/N was not hesitating.

Loona: That's it! That's it! Ah! Come on, N/N! Fuck me like you love me so much! Please!

Y/N: You're really into this. Very well, then.

He then went back to grabbing Loona's neck and started choking her as he kept up the pressure under Loona's pussy.

Y/N: Is this good enough, darling?

Loona: *choking* Mhmm!

Y/N: Thought so. You see, Loonie-Toonie, I wanna do what I can to make sure you get the proper attention. Because you are my mate! And I intend to pleasure you when it comes to this kind of stuff.

Loona: *choking* Oh, really? If that's so, then what were to happen if I were in heat at work? Or anywhere, for that matter? Would you be able to pleasure me? Because this heat is uncontrollable.

Y/N: We'll be sure to find a safe spot to have our mating session. But, on the other hand... If you're really into me owning you, then perhaps we can make some arrangements.

Loona: *choking* Yeah?

She then turned around to her stomach and stuck her butt out in front of Y/N.

Loona: I should remind you. Many people would die to get a taste of this piece of ass. They can't resist to how mesmerizing and good my ass looks so badly, they crumble and beg. But, let's see if just the sight of my ass is enough to perk you up to- OHH!!!

Loona wasn't expecting Y/N to slam his dick into Loona's butt. She cried out as she felt Y/N's dick hitting her where it feels good and pleasuring.

Y/N: So? How you feeling? You feel better, knowing that your dreams about this are coming true?

Loona: Yeah! Yes, yes, yes! Please, N/N, don't stop! Keep fucking me until I pass out! Pin me against something where I can't move!

Y/N: As you command, you dirty dog.

He pinned Loona against the bed as he kept up the pressure.

Loona: Yes! Yes, yes, yes! That's it! Please, N/N, please! Keep going! Ah!

As he kept going, Loona's heart shaped eyes rolled upwards as she could only feel Y/N's dick and her mind was shutting down. She couldn't even feel her legs. However, she gasped as she felt something rise up in her and Y/N was feeling something rise up in his dick, as well.

Y/N: Rrgh! L-Loonie, I... I'm gonna...!

Loona: *thinking* O-Oh, God! Oh, God! I-I feel something... rising... in my pussy! I-I think I'm gonna cum! ... N-No! No, I wanna enjoy this more! I just have to hold on a little longer! I just... have... to hold on...!

Unfortunately, they both could hear a drop of water drip in a pond and that was enough to make both of them cry out and moan.

Y/N: LOONA!

Loona: Y/N!

After they said each other's names, they both felt themselves leaking from their waists as they finally came inside each other.

(Back To Normal)

After they both finally came inside each other, they both were a sweating mess and were panting very heavily as their body odor swelled up the room. Y/N used his remaining strength to use his magic to open a window to let the outdoor air in. Soon, Y/N collapsed onto Loona and rolled off of her to her side as they still kept panting.

Y/N: Hah... Hah... Hah...

Loona: Hah... Hah... Hah... Y-Y/N... W-Why...?

Y/N: W-Why... what?

Loona: Why did you... keep this... a secret? Y-Your dick... is... so perfect... It's as if... I've died... and gone to Heaven... And you... are there... by my side...

Y/N: I-I didn't... think it was... i-important... to bring up... My body... I can't feel anything...

Loona: My mind is... completely... shut down... You... You just... did everything... I dreamed... you would do. Only... you amplified it... and it felt... so good... than it did in my dreams...

Y/N: I... I'm glad... you feel that way...

They both continued panting heavily, but they both held each other's hands and smiled as they looked at each other.
