Summer was in full swing. You and your group of friends made a plan to go to the beach in August, and the night before the trip, you were unbelievably excited. You couldn't wait to relax under the sun and go for a swim.

When you and your friends got to the beach the next day, you all ran out of the car and grabbed a nice spot near the water, laying out your blankets and inhaling the salty sea air.

"______, do you want some French fries?" One of your friends asked as he headed towards the food stands. You squinted at him, the sun beating down on you, as you shook your head.

"No thanks!" You replied before turning to face the foamy water that washed against the sandy ground. It was practically calling you.

"_______-kun!” A girl called, her voice familiar. You smiled and faced her, trying your best not to blush. She was your girlfriend, and her swimming outfit was the cutest thing you had ever seen.

"Rin," you said her name and walked up to her. She clung to your arm and grinned at you.

"Do you want to go for a swim?" She asked, her big blue eyes reflecting your image back at you.

Rin was a great girl, and you really loved her, because she thought about things in more or less the same way as you. It was almost as though she could tell that you were itching to go for a swim in the boundless blue.

"How'd you know?" You asked, playfully poking her cheek.

"Aw, come on, _______-kun, you'd think I'd know my boyfriend well enough...besides, I'm feeling it, too. That urge to splash around like a little kid!" She giggled and you gently pecked her nose, making her blush.

"You're adorable," you said. Her face was even redder now. "Come on, let's get our feet wet already."

You pulled her into your arms and ran towards the water, shivering as the cool liquid splashed under your feet and between your toes.

"Cold?" Rin asked, dipping her feet into the water and wrapping her arms around herself. "W-We'll get used to it!"

With a nod, you trudged out further, Rin taking your hand and interlocking her small, slender fingers with yours. In a matter of minutes, the water was up to your torso. Rin squeezed your hand as she started to swim and the gravelly surface beneath your feet disappeared.

"It's f-freezing," she exhaled, holding onto you. You nodded and started to swim with her.

A few minutes passed and the two of you ended up far from the shore. Your friends were specks in the distance. You were starting to feel alone with Rin. A nice kind of alone. 

"It's so quiet out here," the girl grinned, pushing her blond bangs out of her eyes. 

You nodded, unable to keep a smile off of your face. She draped her arms around your neck and inched closer, letting her eyelids droop to a half-close. You were about to kiss her when suddenly, she yelped.

"W-What happened?" You asked, holding her by the arms. She shivered, a fearful expression in her eyes.

"Something touched me," she whispered. "I swear, _______, something freaking..."

She screamed as she was yanked into the water. You grabbed her arms and pulled as she screamed and sobbed, flailing her legs. Something was clearly holding on to her and it seemed very strong and persistent.

"Rin!" You cried out, worried that you might be pulling her too hard. "You have to try harder!"

"I can't, I can't!" She shook her head wildly before letting out a bloodcurdling scream. The water around you two started to turn crimson. A horrifying image flashed through your head as tears streamed down your girlfriend's already wet face.

"____-" she managed to cry out part of your name before her hands slipped out of yours and she was pulled under. The next few seconds passed by with you acting instinctively.

You took a deep breath. Dropped down, under the water. Everything was blood red and Rin was nowhere in sight. Blindly, you flailed your arms around, trying to find her body. Finally, after what felt like forever, you felt her arm in your tight grip.

Coughing, you splashed to the surface and looked at what you had found. It made you go pale, because it wasn't Rin at all, or rather, it wasn't all of her.

It was only her arm.

With a sudden cry of fear and disgust, the bloody, mutilated limb slipped from your hands. Your heart pounded and you weren't sure what to do.

Call for help...?

As you opened your mouth to yell out for aid, something thin and smooth brushed against your legs. Your throat tightened as you started to hyperventilate, taking slow, careful steps towards the distant shore.

"One step at a time," you told yourself, trying to cope with the fact that your girlfriend was dead. "We can deal with this once we get to..."

You stopped. Two things that felt very much like hands clasped onto both your legs. You contemplated trying to kick off whatever it was, but before you could, you were yanked downwards under the surface of the cold blue.

Darkness took over your vision. Your cries and calls came out as bubbles as you started to run out of air, feeling yourself sink. Two hands were wrapped around your torso. They held you tightly, almost to the point of pain. Whatever the thing holding onto you was, it was dragging you along with it in some direction, and you were still flailing and out of breath.

This is it...no more air...

Something soft met your mouth and you felt something pry your lips apart. It breathed into you as it pulled before shoving you upwards. Your eyes shot open. Sunlight drenched your cold, wet figure and you caught a breath just before you were pulled under once again.

After a few more moments of darkness, you were dragged out onto a small, sandy patch of land. Your face hit the sand and you coughed repeatedly, exhausted, terrified and confused.

"Hmm..." You heard a soft giggle. "You really didn't think I'd let you run out of air and drown, did you, my sweet? I wouldn't let you die so easily..."

Groaning, you looked up at the teal haired girl looking down at you. She was smiling widely. Her eyes were a teal hue that was just like her hair. Before you could move, she brought her hand to your face and ran her fingers along it, sending shivers down your spine.

"You're even nicer looking than you seemed," she purred. You continued to groan, feeling dizzy and a little nauseous. "We can't have you protesting to this, so..."

Suddenly, she roughly knocked a fist against your head, making you cry out. She climbed onto you and admired your face, your expression twisted with pain and confusion.

"I haven't found a prize like this for years," she lowered her mouth and pressed her soft lips to your neck. Your body couldn't move or push her away. "_______-kun, you really are something special..."

Her deft tongue flicked out against your flesh, back and forth. The touch was cool and gentle. She gripped your wrists with one hand, tightly, almost to the point of pain, and pushed them over your head as she continued to glide her lips and tongue along your neck and jawline.

"Honestly," she began, finally moving her mouth away and then pressing her nose to yours. She stared into your fear-filled eyes and smirked, "I don't see what you ever saw in that blond girl..."

The woman pursed her lips together thoughtfully and sat up straight, tracing a finger down your cheek, along the length of your neck and then your chest. You couldn't speak out against it or move much, but you managed to shiver in response to her touch.

"Well, it's not like it matters," she continued, stopping for a moment and taking her lower lip into her mouth, and then leaning close to your face again. "She's gone now, and that means I can have you all to myself."

She closed her eyes and firmly pressed her full lips to yours, lying on top of you and kissing you lustfully. Her long locks of hair cascaded over her and you. She pulled back slightly, her eyes half closed, and licked your lips before kissing you again, this time thrusting her warm tongue into your mouth. It ran along your teeth before exploring every inch of your mouth. You didn't realize then, you were too panicked and hurt to even think straight, but this was only the start of it all.

This woman would be the only girl to touch you for the rest of your life.

T_T I can't do yandere...at all...
