A/N: requested by Silicsan000. Enjoy.

Of all the birthdays that you've had over the years while you were growing up. But the birthday that was coming up would probably be the one that would change the rest of your life forever. 

(Y/N): "sighs" god, I hate the damn rain.

Today was your birthday, you were walking from your house to go visit your girlfriend. However, you had to do this while having to walk through the rain. 

(Y/N): I swear, If there's one thing I hate more than anything, It's rain. He's always non stop with this crap falling down from the sky and I always haft to dry my damn clothes.

You said to yourself as you kept walking through the empty wet street all by yourself. After you by a sewer drain, you then started to hear a voice come out from the sewer drain.

???: hey there kid.

(Y/N): hm?

You looked around to where the voice was coming from but didn't see anyone there.

(Y/N): what the?

???: down here.

You then looked down near the sewer drain. You didn't see someone there at first, but you then saw a head pop up from the drain and show themselves to you. It was a woman dressed as a clown.

(Y/N): uhhhhhhhhhhh.........

???: heya, (Y/N). Walkin out here in the rain alone I see?

(Y/N): okay, I'm just gonna walk away now.

???: awww, now hold up there, kid. I just wanna talk to ya.

(Y/N): just who the hell are you and how do you know my name?

Penny: I'm pennywise, the dancing clown. But you can call me Penny for short.

(Y/N): ooookay, that still doesn't answer my question on how you know my name.

Penny: oh, I know the names of all the good little boys and girls. It's what we clowns do.

(Y/N): yeah, that's not creepy at all. What's a clown doing down in a sewer anyway?

Penny: oh, the circus I was in got hit by a storm. And I was washed away into the sewers ever since.

She said, lying through her teeth.  

(Y/N): right. Well, what do you want?

Penny: well, I heard your birthday was coming up. So I'd thought I'd give you a balloon. 

She said as she held out a red balloon from the sewer.

Penny: go on, take it. 

(Y/N): uh................. I don't know about that.

You said as you slowly stood back a bit.

Penny: aw, come on now. I promise I won't bite.

She said as she kept holding the balloon.

(Y/N): look, I like the offer, but I can't really accept stuff from people I've just met. 

You said before turning around.

(Y/N): plus, I've got to hurry and visit my girlfriend.

Penny nearly growled a bit from hearing this. But she kept her cool and spoke again.

Penny: very well. I'll just be on my way. 

You turned around to look at the clown woman again, but she was gone, leaving the red balloon tied to a bar on the sewer.

(Y/N): .........weird.

You said before walking off. Meanwhile, at (G/F/N)'s house, (G/F/N) was in the tub, cleaning herself and getting ready to give you a little "birthday surprise".

(G/F/N): "sighs" It feels nice getting ready to give my boyfriend a little birthday surprise.

She leaned against the end of the tub a she let herself soak in the water and she closed her eyes in relaxation. However, what she didn't know was that she wasn't alone. A small fin popped out of the water and started to move around (G/F/N) as she no clue it was there due to her eyes being closed. It wasn't until the fin gently brushed against her arm. 

(G/F/N): h......huh?

Just as she opened her eyes, a pair of sharp dagger like teeth clamped into her waist and before she could let out a scream, she was pulled down into the water, almost as if the bath was turned into a pond with deep water. She thrashed around and screamed as the unknown creature that was attacking her. She pulled on to the side of the tub and tried to get out. But once she managed to pull herself up to the side of the tub and scream for help, her head was bitten clean off by a shark like creature. The whole at her neck spewed out blood like a volcano as her body fell and was dragged back into the water.

(Timeskip).

You eventually made it to (G/F/N)'s house. You saw a sign that said come right in and follow the trail of rosebuds.

(Y/N): rosebuds? This is kinda new.

You followed the trail of rosebuds until you eventually reached her room and was surprised to see (G/F/N), standing there, naked. 

(Y/N): (G......G.......G/F/N)?

(G/F/N): hey babe. Surprised?

(Y/N): uh .....y.....y......yeah. You look ..............amazing.

You noticed that she was a lot bustier than she usually is. She saw this and smirked.

(G/F/N): you like my new "balloons"?

(Y/N): y...y......yeah, I guess.

(G/F/N): then come and feel them. After all, they're for you, birthday boy~

You walked over to her and pressed your lips against hers as you then placed both your hands on her boobs. She smirked as you two both fell on the bed, with you on top of her. 

(Y/N)'s mind: hm...... something doesn't feel right here. I've kissed (G/F/N) before, but for some reason, it feels a lot different.

That when you soon noticed something from the corner of your eye. It was the torn up and decapitated body of (G/F/N) and her chewed up head was floating in the blood filled water.

(Y/N): what the fuck?!

You said before you stopped kissing and moved up to try and go in the bathroom to look closer, but a pair of arms and legs wrapped around you. You looked down and saw that it wasn't (G/F/N), but the clown woman from before.

(Y/N): ?!

Penny: come on birthday boy, we've just gotten started.

(Y/N): You fucking crazy clown bitch!

You were angered that she killed your girlfriend and grabbed tightly on her neck. She just laughed like it was nothing.

Penny: where I'm from, we all float.

(Y/N): Shut the fuck up!

Penny: and when you're down here with me forever......YOU'LL FLOAT TOO!!!!!

She yelled before the bed opened up into a hole and you both fell into it. Your screams and penny's laughter echoed through the hole before it closed. After that day, you were never seen by the public again, forever in the clutches of the insane killer clown.

A/N: next is Yandere Caulifla x Male Reader.
