Well hello readers, and welcome to my story!

I haven't been alive for ever, so once I learned this in school I figured... why not? Because it happens in life and I don't think a story has ever talked about things like STDs and the like. As much as you like your characters having sex... well, reality would like a word with you.

Despite this having Miku/Gakupo in the beginning, you all know where this is going to go. And because while writing about them, I became fond of Yukari/Ia so expect their own story shortly after this one as a stand alone.

And yes, this is mainly about the exam and is rushed, but it's sort of the main part of the story and I wanted it out of the way.

Chapter One: The Start of... Everything

Hatsune Miku loved men. She loved their bodies, their voices, their heights... everything about them, she loved them. She loved how they could walk around with little to nothing and it would look fine, and their abs would show, teasing her itching fingers when they flexed and when the guys on the swimming team threw their shirts off to jump in.

One in particular was Kamui Gakupo; his silky purple hair slid through her fingers and elegantly dropped back into place within seconds. Despite his feminine features, he had a strong jawline, sharp, beautiful purple eyes and was taller than most guys he hung around. Not to mention his body was perfectly ripped from top down. So once he made a move on her, Miku jumped at it and didn't regret making out with him during practice.

"I can see you guys are so into each other," Yowane Haku commented as she appeared from the water, her cap keeping her massive amount of hair in place. She was a pretty popular girl who talked a lot but cowered in the face of a guy named Dell. He was a guy who dyed his hair and smoked during breaks and stunk pretty bad most of the time but had this cool, delinquent charm to him Miku almost liked as well. It was obvious who she was checking out, and Miku smirked and poked Haku's cheek to snap her out of it.

"And I can see you know exactly who you're into," she teased quite loudly, running a hand through her slightly damp hair with a chuckle. Haku dunked her head in the water when Dell curiously looked over at them, cheeks almost as red as her eyes and glaring straight at the tealette.

Standing, Miku smiled over at Gakupo who started to walk out with some of his friends, most of them running over to the girls' side to chat with their female friends and girlfriends, the purple-haired one included. "Hey," he coolly said, throwing the towelette in his hand over his shoulder. Gakupo tossed Haku a friendly smile and slowly let it slide into a cocky, lustful smirk as she stood in front of Miku, placing a hand on her thigh. "Hey."

Miku looked around with a small hum and smiled back, "Hey you." Her hands traveled up to his shoulders and stayed there, not even caring if people glanced at them to complain to their friends. Gakupo was worth the rumors. "So, what are we doing tonight?" she asked innocently, rubbing a lock of his hair between her thumb and index finger.

The moment was utterly ruined when Haku squealed at the feeling of someone groping her chest, and everyone looked down to meet with shining golden eyes as they emerged from the water. Akita Neru's signature Cheshire grin plastered on her face like usual. "Keep dropping your guard, Haku," she teased with a wink before back paddling away from the blushing grey-haired girl.

"Haah, she's so annoying," Miku sighed against Gakupo's chest, glaring at the loud obnoxious blonde jumping out of the pool to meet with her dorky friends. He laughed at her truthful words and stepped back to peck her on the lips, hearing their coach begin their class for the day. Miku pulled him back before he could go and crushed their lips together, forcefully sticking her tongue in his mouth.

"Bleh, they're at it again," Yuzuki Yukari gagged while walking by the two, throwing the dirty towels into the bin near the door. The light sweater she wore over her bathing suit hid everything from behind and left her legs to anyone's imagination, regretting that decision once she felt someone's palm brush against her leg. Not even having to look at them, Yukari rolled her eyes and came face to face with her very own playgirl. Ia.

The swimsuit she was wearing was, of course, one size too small just because she wanted Yukari's eyes to be fixated on her body, and when that didn't work she placed both of her arms on the purple-haired girl's hips, teasing them slightly and making her blush. "So, what's up?" Ia winked, pressing their foreheads together. "Jealous of Hatsune getting some and not you?"

Yukari laughed and swiftly escaped from Ia's clutches, pushing the cart of dirty towels into the locker room for a wash. "Yeah right!" she yelled, knowing the other girl was following her; Ia would never pass up a chance to get her alone. Yukari felt her breath on her neck when she was putting everything into the small washing machine and moved a little to get the detergent, not even caring when she felt Ia's hands feeling up her butt.

"Do you get some sort of kick out of molesting people?" Miku's cocky voice called, having been watching their exchange since Yukari's comment. Behind her, Gakupo was trying hard not to look but at the same time couldn't help peering inside the locker room.

Ia coughed into her palm and tore her body away from Yukari's, the purple-haired girl not even flinching at being caught and instead rolling the cart into the storage room where all the gym equipment sat. "Oh? You're one to talk," Ia laughed, crossing her arms. "Everyone knows how much of a skank you are."

Yukari flinched at that, not ever hearing her being so insulting to anyone and actually meaning it, and although she wasn't Miku's friend and hardly knew her, she knew that wasn't entirely true. But she could only stare in confusion when Miku laughed a little with a shake of her head, "I know, and I don't care about it. Too bad you can't enjoy the feeling of having sex with a guy... even if you open your legs nobody will want to touch you."

"Okay, all of you out!" the coach yelled, blowing his whistle in Gakupo's ear and making it go deaf for a few seconds.

The three hesitated but eventually sighed and dragged their feet out of the locker room and back into the pool for their practice to start, Yukari watching as Ia and Miku competed against each other constantly. It made her wonder about their relationship.

He groaned as he pulled out of her for the third time that night, dropping to his side with a tired smile while she looked like she already got a full night's rest. The digital clock behind her told him of how early it actually was, and Gakupo scratched the back of his head with a yawn, "You sure you don't want to go to Lily's party tonight?"

Miku sighed against her pillow and rolled her eyes, popping her fingers through a stretch, "Nope. she's an ass and she didn't even call me to say she was having a party." She rolled over and closed her eyes, although it was useless as she wasn't tired at all. "You can go if you want though."

"Nah, not if you aren't," Gakupo replied, wrapping an arm around her waist. Miku felt something akin to bile rise up in her throat and jumped out of bed with cold sweats, running into the bathroom of her dorm. Gakupo called out for her a few times and eventually sighed in irritation at what he had fallen into, hurriedly getting ready and slamming her door on the way out. She knew he'd be back, since he was always getting

Miku bit her fingernails, and shook her head, knowing who to go to so she could get rid of her thoughts that were filled with unnecessary guilt. Gakupo was hot so she wanted to sleep with him and nothing more; once he started acting like they were dating and got overly intimate, that's when she felt an uncomfortable itch on her shoulder.

Walking down the hallway of her floor, Miku reached another and knocked loudly, already hearing the person's music leak out from the cracks in the door frame. A few seconds later, Gumi emerged with gaming headphones over her neck and her hands full with a Cup Noodles, steam rising into her face and the smell of the chili powder making her stomach growl.

"What's up?" Gumi greeted, grabbing the remote and turning down the sounds from her TV, whoever was performing going nearly mute. On a smaller TV, a shooting game left on pause and Miku rolled her eyes at how much of a nerd Gumi was, so she commented on it. "I know right?" the greenette grinned, sitting on her bed.

Miku shook her head with a smile and looked out the window to the boys' dorms, "So I slept with Gakupo... we finished like... ten minutes ago." She didn't mind that Gumi had little reaction; the girl was prone to being unemotional with everything that didn't relate to her. Being possibly the only out lesbian on campus and getting heat for it, there wasn't much Gumi could do.

"You and him still together though?" she asked while slurping a few noodles into her mouth, the broth spilling on her hand. Miku swiped it with her finger and licked it, looking up with a confused, dull expression. "Taking that as a no...?"

"Not really... I mean we weren't together, and then he just started acting like we were and I didn't like that," Miku admitted, looking up to meet with green eyes full of understanding. Gumi was a great friend and she wanted to find her a girlfriend who could love her as much as Miku did. Platonically of course.

The rest of the night was spent messing with people on Facebook and causing a huge fight between Miku and a girl named Galaco, before Gumi leaned on her shoulder and continued her game while glancing between her computer screen and the second TV she had her attention on. Miku didn't mind it much and returned the favor by dropping her head on top of Gumi's, both of them sighing.

"We need someone to date."

Shion Kaito was Miku's next boy toy, and they were immediately caught having sex by someone who ended up getting beaten up by the naked couple, promising to keep quiet about it despite how obvious they were. After about a week and getting bored, Miku arrived at Gumi's room once again after their short relationship ended, finding her in the same place as before, although this time she had an alternate outfit due to the shift in weather. With summer approaching it was definitely getting hotter outside and a perfect excuse to use the school's pool more than usual.

"You know, I'm getting this small... itch," Miku explained, looking down at her thighs in embarrassment. Haku watched her carefully with a serious expression, her arms casually on the border of the pool. Lifting one of her legs, Miku showed her the family of red spots and felt a shiver once Haku's face fell. "And they just won't go away no matter what I use!"

Haku hummed and shook her head against the concrete, "I don't want to be the bearer of bad news, but... don't you think it's an... STD?" She winced when Miku's foot pressed against her head, trying to force her down in the water as if that'd make the words she just said disappear. Coming back up with a coughing fit, Haku pulled her in and laughed when Miku began to freak out.

"You asshole!" Miku laughed, peeling her hair away from her face, shaking it out like a dog as much as she could. But with how long her hair was, it was useless. Then she looked down and frowned, "It's not an STD. It could just be heat rash, since it's getting hot and stuff..."

The grey-haired girl gave her a look and Miku rolled her eyes while her cheeks began to heat up, "Fine, I'll go to the... ew. Gynecologist..."

So after convincing Gumi to break up with her video game for one day and dragging her to the doctor, Miku was literally crushing her hand while they walked in, the nice nurse not able to ease her nerves. Sitting in the waiting room, Miku shook in place, her handwriting sloppy. "I can't do this," she whimpered, looking beyond the hallway that led to the rooms.

"What if they... try to touch me?" she asked, freaking out once a thought came to mind, "What if it's a guy?!"

Gumi sighed and covered her mouth, "Miku. Shut up. You'll go in and they have to check you down there, then they'll say it's some regular rash and bam, we're out. Now stop freaking out."

After going through her Facebook and talking with Gumi for a little longer, Miku jumped when a male voice called her name, Gumi giving her a smile as they both stood up. "Ah, only Hatsune Miku please. We want to make this as invasive as possible," he said, blinking when Gumi simply walked passed him.

"I think it's less invasive if someone she knew went with her," she said, grabbing Miku's hand to calm her down. He nodded and led them into the hallway, and then stopped to do mundane things like height and weight before they went into a room that was overly bright from the open window and too clean for her liking. What unnerved her even more was the sight of stirrups, which looked more like something out of a horror movie than something at the doctor.

The male nurse did some other mundane things and took her temperature, asked her to breathe in and out while placing a stethoscope on her chest and finally asking about her issue before he informed her of the doctor coming in to see her. "One more thing: are your periods normal?"

"Yes," she answered with a shaky breath, notifying him of her nervousness.

"Okay..." he mumbled, writing it down on the paper, "And are you sexually active?"

Gulping, she exchanged looks with Gumi and decided she was going to be truthful, "I am."

"All right. I'll leave you on your own for a bit and the doctor will be here within a few minutes."

Leaving with a gentle shut of the door, Miku sighed and slumped on the heightened bed she was sitting on. "He was so cute..." she mumbled, once again taking her mind off of what was to come.

Gumi shivered herself and rubbed her arms, "This would be the first time I'll see another girl's vagina..."

"If I wasn't sitting here with a burning rash or at a gynecologist's office... I'd murder you for saying that," Miku whispered, hearing someone stop in front of the room.

The door creaked open and a smiling woman with long pink hair walked in, her eyes fixated on the clipboard she took off the door before looking up and closing her eyes. "Good morning, I'm Megurine Luka," she lifted up her badge as if they accused her of being fake, and then bowed to them before giving her attention to Miku. "So, can you please go into detail about what's causing you issues?"

Miku gulped and nodded, tightening her hold on her shorts. "Well, a few days ago, I noticed this... burning... feeling, between my legs. When I went to the bathroom and checked, there were these pimple-shaped bumps on my skin and I sort of freaked out," she explained, her cheeks growing hot from having to say such embarrassing things. Luka nodded and wrote something down before setting the clipboard to the side followed by reaching into a box of latex gloves. Gumi stood up and Miku saw that her cheeks turned red, meaning she must have regretted coming in with her after all.

"Hatsune-san, if you wouldn't mind, could you please strip down while I get some supplies?"

She opened up a drawer with paper gowns inside and looked back up, "Can you also put this on?" Luka asked politely, her gentle voice soothing Miku's nerves a little. Gumi sat back down as her white coat fluttered by, and let out a deep breath once she was gone. She looked over at Miku, who was shakily getting off her seat and slowly unbuttoning her shorts with short, frightened pants of air.

"Don't be scared. She seems nice," she said, looking down to her phone when she saw Miku's clothes slide down her legs before reaching down for one of the gowns. A few seconds later, almost fast as lightning, Luka was back in the room with a tray of things, nodding at the sight of Miku sitting again with her shorts folded on a the chair next to Gumi.

Miku shivered when Luka lifted her chin and placed her fingers on her throat and jaw, Miku gulping making her laugh a little. "Okay, all's fine here..." she mumbled, stepping away to write something down.

Luka placed her now gloved hand on Miku's knee and smiled, "I'm going to check your breasts for any abnormalities, okay?" She waited until Miku nodded and then let her pull her gown down to show her chest, and placed her fingers over Miku's breasts, slightly feeling around but not in a perverted way that it was uncomfortable. "All right, they seem fine to me," Luka smiled, scribbling something on her clipboard again before looking over at the stirrups.

"Okay, Hatsune-san, we're going to the main part of the exam, so what I want you to do is lift one leg at a time into it and then sliding down to lie on your back, okay?" she asked, helping Miku off her seat and leading her to the place where she was to sit. Gumi watched with interest, although she couldn't see anything as Luka was slightly blocking the way, which might have been for the best.

Miku felt her cheeks grow red when her legs were gently pulled apart, glad there was a towel covering her lower region so she didn't have to see it.

Luka held up a metal item and looked down at Miku, looking back for a second to greet the nurse that was walking in. "A little late, Yohio-san," she teased, ignoring his mumbles. Going back to Miku who looked a little uncomfortable, Luka tapped her legs, "It's fine, he can't see anything. Now, I'm going to be collecting some cells to analyze later, so this may feel a little uncomfortable but shouldn't hurt."

Her teal eyes locked with Miku's, and the tealette felt a sort of pang in her chest with how gentle and calm the woman was. "If it does hurt at any moment please tell me..." she said before going in and inserting it. Miku felt incredibly awkward, even when Gumi walked up to hold her hand again.

"Hatsune-san," Luka announced as she walked back in with a manilla folder of papers, all from the exam. Miku's eyes widened at how fast it was. But they fell when Luka didn't look too happy, or as calm as she used to just a few minutes ago. "The test results were quick yes, and unfortunately..."

She felt tears in her eyes and wanted to disappear, especially when Luka looked so defeated despite not being the patient.

"You have a HSV infection. Now what that is, of course, a sexually transmitted disease, commonly known as herpes. But luckily you came in during its very early stages and you'll be prescribed to antibiotics and given creams to calm down the outbreaks." Luka didn't make eye contact with her once, especially once she mentioned outbreaks; Gumi on the otherhand, stared at Miku's slowly breaking down face as tears welled up in them.

"I'm sorry, Hatsune-san," Luka apologized, shaking her head. A smile appeared on her face again and she shook her head, "Don't worry, this won't prevent you from doing everyday things, and it doesn't mean you can't continue your sexual activities. However, make sure your partner is aware of this and gets tested themselves if they gave it to you."

Miku nodded blankly, her eyes focused on a spot on the ground and not the information Luka was giving her. "All right... thank you..." she dully said, feeling dead and drained. Luka had applied some lotion on her legs before they finished the exam to stop the burning, and it did indeed help.

She wasn't an idiot and knew that herpes was some disgusting disease, but she never expected herself to ever get it nor did she expect it to happen more than once. She was literally stuck with it for the rest of her life.

"This sucks..."

Her love of men had suddenly disappeared with the rest of her usual happy attitude.

I know. I know. OMG GROSS right? But, well, I haven't read anything about this, so while Len might be a playboy, he's never gotten an STD from it and I wanted to write something since it just piqued my curiosity.

Hope you liked it; review, favorite, follow and I hope to see you guys next time!
