"Outstanding! Just Brilliant! That was another great show Ayu!" the pop star's manager complimented as she followed the orange haired and fair skinned model off the stage, handing her a water bottle with one hand while gently patting beads of sweat off her forehead with a white hand towel.

"Thanks! The fans were really intense tonight." Ayu said, accepting the water-bottle, unscrewing the cap and bringing it to her lips for a drink.

"Is the limo ready yet? I'm exhausted." she says, looking to the dark haired manager who frantically perked up.

"Ah! I'll go check on that for you right now! I'll be right back!" she says, scrambling off with a walkie-talkie in her hand so she could locate the right staff.

Ayu sighed and stretched her arms, throwing the towel over her shoulder gently and sitting on a white sofa backstage. After a full day of dieting, practicing, signing fan photos, and performing, all she could think about was getting home and into the bath for a nice long soak.

"That was a fantastic show Ayu!"

A voice sounded off, which startled the pop star who had previously thought she was alone in the room. Ayu quickly sat up and opened her eyes to see a pretty girl with fair skin and mostly purple hair that faded to a dark blue at the tips. This hadn't been the first time she had seen the girl either. As many fans as Ayu had, this one stood out. She wasn't so sure if it was because she saw her so often or because she was pretty, but even now upon her appearance there was no doubt she was a super-fan of hers. The only question was-

"How did you get backstage?" Ayu asked, quickly realizing she must have sounded more rude than she originally anticipated.

"Oh, the door was unlocked so I just sort of came in…" the girl answered, suddenly looking a little disheartened by Ayu's response. The Idol felt a little chill go down her spine. If this really was a superfan, she needed to be more careful about how she treated her.

"Sorry, what's your name? I think I recognize your face. You often come to my photoshoots and fan meetings right?" Ayu said, which in turn made the girl's face light up, a completely different expression from what she was making a few seconds ago.

"Oh! I knew you'd remember me! My name is Cosmos!" she replied, walking closer to her.

"Cosmos? That's a pretty name!" Ayu said, quickly standing up from her seat. The closer the girl got the more angry she felt, wondering where all of her security guards had gone all the times.

"Really!? You think so!? The great Ayu thinks my name is pretty!? What a dream come true!" Cosmos answered excitedly, so close now they were nearly toe to toe.

"You have to let me take a picture so I can remember this moment!" Cosmos said, pulling out her cell phone from her back pocket.

"Oh- of course! Anything for a fan!" Ayu decided to play along, afterall, it was the best thing she was going to be able to do to remain safe until someone would return to help her.

Cosmos excitedly jumped to the idol's side, holding her phone up in the air and flanking her side in a half-hug, as if the pair had been long lost best-friends for years. Forcing a convincing smile across her face, Ayu posed for the photos two or three times before Cosmo finally was satisfied to pull away from the girl, holding the phone close to her face as she reviewed them.

"Wow! Your breasts look amazing in these photos! I mean, of course they would! They're so large and perky!" Cosmos said, lowering her phone and looking directly at Ayu's breast, which shocked the idol.

"Oh. Uhm-" Ayu began,

"Hey! You're not allowed back here!" A security guard came racing over to the pair, grabbing Cosmo's by the arm.

"Ah! I guess I'll be going now! I'll see you around soon!" Cosmo's called out as she was already being pulled away by the man who was twice her size.

Ayu, still left a bit dumbfounded by the whole situation, slightly raised her hand and waved at the girl as she was taken away through the back doors.

"Ayu! Your ride is here! Let's get going!" her manager appeared from around the corner.

Ayu flicked her finger from behind her sunglasses, letting the dark shades flip down from atop her head and onto the bridge of her nose as she stepped-out from the car in her white flip-flops. The idol had just arrived at the beach, and was wearing a tight bright yellow swimsuit that hugged all of her curves in just the right places, her long wavy orange hair flowed around her body as a gentle breeze greeted her and the handsome bodyguard who stepped out of the car next.

"It's a beautiful hot day to be at the beach, isn't it Ren?" she asked the tall blonde guard, who nodded his head in approval silently, already surveying the area for any signs of danger.

"I'm sure if there are any fans here, it'll be fine." she assured him, grabbing her purse as the guard closed the door and followed her down to the beach. Even though Ayu knew most of her fans had been harmless, there was one individual that popped up in the forefront of her mind, Cosmos. A super-fan that she had seen so often lately, she had no choice but to know her name unlike the rest of her fans. As her feet touched the sand, she gazed about the water shoe and along the dunes. Despite the nice weather, the beach was only a little crowded as most people were still likely at work during this time of day.

'Even that Cosmos girl probably has to take time out of stalking for work right?' she wondered to herself as she failed to see any signs of the purple-haired girl lurking around. Perhaps for once she'd be able to enjoy her time out without running into her.

Before long, Ayu made her toward the water. Having her guard, Ren, set down a large beach towel and umbrella, as well as a couple of chairs to sit in.

"Ren, I'm going to sunbath. Could you run to the concessions and fetch me a drink or two. It seems I forgot to pack water bottles." Ayu said.

"Ayu, my priority is to keep you safe when you're in public, if I leave you to do get drin-"

"Ren, I'm still your boss. If I say it's okay, it's okay." Ayu interrupted before the bodyguard could protest any longer, shutting him up quickly as he bowed his head.

"Yes ma'm. I will return with drinks shortly." the guard said reluctantly, bowing his head and turning away from the idol to run to the concession stands.

Ayu sighed and watched him go, grabbing her beach towel and pulling it out from the shade of the umbrella. Once it was under the sun she got down on her knees to lay down on her stomach, sighing as she felt the warmth of it's rays down on her back.

"This is nice" she said to herself, crossing her arms and resting her head on them, watching a family a few feet away build a sand castle for a couple of minutes before she closed her eyes to fully relax. As she rested, her mind kept wandering to the crazy experiences she had been through with her super-fan Cosmos.

'Why do I have to think about her right now? Finally when I have a day off and somehow I'm stuck thinking about that crazy girl.' Ayu thought to herself. The last time she had spotted her, she had been just leaving from a show when Cosmos appeared backstage with security nowhere to be seen. Ayu had played it off coolly and took a photo with the girl just to keep her entertained long enough for security to come and take her away.

"You should be more careful on a hot day like this! Wouldn't want your beautiful skin getting burned!" a voice sounded next to Ayu. It was a voice she recognized too quickly, a voice that made her heart drop in her chest. Startled, the orange-haired idol lifted her head to see the very fan she had been worrying about. Cosmos.

"C-Cosmos! What are you- ah"! Ayu yelped as the purple and blue-haired girl squirted something cold and white from a bottle onto her back. It was sunscreen, and before Ayu could move she started rubbing it around her back and shoulders, careful to avoid getting any on her swimsuit.

"I can't let my favorite idol get sunburned now can I?" Cosmos asked, acting completely normal as if Ayu had invited her to the beach herself, and that they were meant to meet up.

Ayu wanted to push the girl away, but she was quick to admit in her mind that the sensation of her hands rubbing down her back and shoulders felt really nice.

'Why is she so good with her hands?' the idol wondered to herself, relaxing a little again despite still being a bit freaked out.

"Cosmos, what are you doing here?" Ayu finally was able to ask once her mind and heart had calmed down a little.

"Hm? It's hot today isn't it? Anyone would come to the beach on a day like this. I could spot you a mile away even in the most crowded of places with that beautiful orange hair of yours!" Cosmos said, slowly sliding her hands down the center of Ayu's back, moving towards her legs next.

"Ah- I suppose so-" Ayu said, unable to come up with a quick argument for that.

"I had the day off today, so I really feel lucky that I was able to run into you here. I know you must be really stressed because of how hard you work all the time...it would really mean a lot if you let me treat you for the day!" Cosmos said while massaging the back of the girl's thighs. Ayu closed her eyes, feeling the girl's soft hands squeezing her legs, her fingers pressing on her inner thighs, sending a tickling sensation between them.

"Mmh. Treat me?" Ayu asked, feeling a bit in a daze.

"Yes, I have the whole thing planned out if you'd just agree…" Cosmos said, feeling the idol tremble beneath her finger tips. She gently pressed one hand higher up on her inner thigh, her finger tip just gently grazing the edge of her swimsuit.

"Please? It would mean a lot to me as your biggest fan…" She said quietly, her voice alluring and pleading at the same time.

"W-Well…" Ayu felt her entire body tremble as the girl traced along her swimsuit edge. Even though she liked the thought of that, she was still hesitant about letting the stalker fan do as she pleases. Cosmos smirks as she brings her slender fingers up to the idol's incredibly soft ass before giving it a squeeze causing the girl to moan.

"Ahh~ Cosmos!" The idol tried to scold the girl as she tries to hold her blush, unable to deny how good it felt to have her smooth hands pressed against her sensitive spot. Ayu was unsure herself why the stalker girl was making her feel so good.

"I-I suppose that would be okay…. For my fan." she says finally, giving in to the generous touch.

"Really!? Oh I'm so glad to hear that! Wow I truly feel special!" Cosmos said.

"Ms. Ayu!" a voice sounded, causing both of the girls to look up in the direction from which it came. Running towards them was Ren, holding a few bottles of water in his grip as he quickly approached. Ayu sighed and sat up, holding up her hand for Ren to stop running.

"That's enough Ren." Ayu said, looking up at him sternly.

"But ! That's-" he stuttered.

"I know who it is!" Ayu replied shortly, turning and grabbing Cosmo's hand, much to the fan's utter shock and surprise.

"We're going to go swimming now. I'm giving you permission to relax until we return!" she says, standing up with Cosmos's hand still in her grip, causing the other girl's heart to race.

"But that isn't saf-"

"That is an order!" Ayu cut him off once more.

"Relax, or I'll fire you when I get back." she said finally, turning and pulling a still shocked and love-stricken Cosmo's towards the water.

"Uhm- is everything okay Ayu?" Cosmos asked once the idol let go of her hand, much to her dismay.

"Everything is fine. Ren is just so uptight, it's a bit suffocating at times. But he's a great bodyguard, so I try not to get mad at him." she explained, looking down as the cold waves crashed against their ankles where they stood up.

"Does it make you feel tense at times?" Cosmos asked, looking at the idol, feeling her cheeks burn hot as the sun lit up her beautiful face.

"Yes. I guess it does. That's why I wanted to come to the beach today...to relax and relieve tension." Ayu answered after giving it some thought.

"Say no more! I have the perfect way to relax!" Cosmos said, dragging her along the shoreline.

"W-What is it?!" she asks in shock, though she allowed herself to be dragged along. Before long, Cosmos had brought Ayu over to the pile of available floating tubes, picking up a double-tube that was meant for two. It was dark blue and had two holes for each of them to fit into.

"Tubing?" Ayu asked, smiling a bit.

"That is a good idea." she admitted, giggling a bit as she helped Cosmos take it into the water.

"You sit first! I'll push us out." the fangirl insisted, holding the tube so it didn't float away. Ayu did as was asked, sitting and feeling the waves of the water gently bump into them.

'Maybe I was too soon to judge Cosmos…sure she was a little much at first...but she really does just seem like a fan who was desperate for attention." Ayu thought to herself as she relaxed and enjoyed the ride. Closing her eyes, she was just beginning to enjoy herself in the rhythm of the rocking tube, before she felt Cosmos's cool hands holding her sides, making her open her eyes.

"Cosmos? What are you doing?" she asks, hearing the girl get in the tube behind her.

"I'm going to massage you of course. It's another great way to relieve tension." Cosmos replied, pulling her hands up to her admired idol's shoulders, beginning to massage her fingers and palm into them.

'She's really good with her hands...it's hard to resist..' Ayu thought to herself, closing her eyes again after the girl revealed her intentions.

Cosmos was careful to watch all of Ayu's body language signals, her gaze drifting down to her backside.

'What a cute swimsuit. It compliments her hair color so well. Ayu really is the best.' Cosmos thought to herself, her hands slowly running down her wet arms, before moving onto her breast, leaning further in the tube, she gently grasped both of them in the palm of her hand, pressing into them much to Ayu's startlement.

"C-Cosmos!"

"Shhh. Just relax. I promise that I can make you feel really good...Ayu.." Cosmos whispered into the girl's ear. The sensation of her breath on the back of her ear made Ayu get goosebumps all over her skin.

Ayu felt her heart rate beginning to quick as the girl massaged her hands into her breast. She had such a nice rhythm, such a gentle pressure that it melted pleasure all over her body, and made it hard to resist.

'N-No way...I'm actually enjoying this so much..' Ayu admitted to herself in her own thoughts, shuttering as she felt Cosmos's fingertips pinch her nipple lightly over her swimsuit.

"Ayu...I really love you." Cosmos said, slipping both of her hands now under her bright yellow swimsuit, touching her breast and nipples directly now while her lips fell to her neck, kissing her there gently.

"Ah! S-Someone will see!" Ayu protested weakly, but she made no physical motion to shake the girl off of her.

"We're behind a rock...and your body is turned away from the public eye." Cosmos reassured, shifting her teeth against the girls neck now.

"I won't bite hard...I know you need to show this area when you perform." the fangirl reassured, beginning to lash her tongue against her wet skin, that tasted a bit salty from the water.

"Mmh ah! Y-Your hands" the idol cried weakly, shivering as she felt her nipples rolled by the girls thumb.

"Be honest, am I doing good? Are you feeling good?" Cosmos asked, desperate to hear some sort of approval from the girl she loved. She kissed on her neck again, then slowly ran her tongue along her skin while rolling her left nipple between her fingertips while she patiently awaited an answer.

Ayu desperately attempted to fight the sensation, but she couldn't any longer as she felt the girl lick the side of her neck where she was sensitive.

"Y-yes...i-it feels good" she admitted reluctantly.

"Oh Ayu!" Cosmos said excitedly, leaning in and letting her right hand travel beneath Ayu's swimsuit, feeling where she was warmer between her legs.

"This is where I can make you feel the most pleasure. Just try to relax" she instructed, letting her fingers take the plunge into Ayu's pussy, her two fingers spreading the girls lips before slowly inserting her middle finger inside.

"Mmmmmmmmh! Ah! Cosmos!" Ayu cried out-out, feeling the girl's breast press against her back as she eagerly leaned closer to her in the tube.

"Ayu, your voice." Cosmos warned softly, beginning to curl her finger inside of the girl before pumping it back and fourth slowly, kissing atop her shoulders.

"Mmhh ah! I-I can't help it- your fingers~ they feel so nice!" Ayu said out-loud, squeezing the plastic tube with her fingers as she felt pleasure travel up her spine, feeling the area in between her legs become more slippery.

"Ayu, please look at me." Cosmos said when the idol complained, leaning closer in the tube as the she obediently lifted her head, turning to make eye-contact with the fan Her eyes widened as she suddenly felt a hot pair of lips against hers, muffling her moans of pleasure as Cosmos inserted a second finger, rubbing her harder while her other hand played with her breast still.

"Mmhh hhm" the two girls moaned hotly against one anothers' lips, Cosmos slipping her tongue past the girls lips, wrestling with Ayu's desperately as she was eager to please the idol. Her thumb felt her bud become harder, flicking it against her lip quickly, over and over while invading her mouth.

Ayu's sounds were muffled, feeling pleasure overtake her body and senses as the girl played with her click and fingered her roughly, her eyes rolled back as she felt like every sensitive part of her body was being touched or rubbed on by her love crazed fan.

"Mmmmmmmmmmmmmm!" she cried hotly into the girl's mouth as she was finally brought to an orgasm, feeling the pleasure crashed through her body harder than the waves did, rolling over her over and over and making her slim hips buck against Cosmos's fingers as she came all over her fingers.

Cosmos slowly parted her lips from Ayu's, smiling as the idol gasped for air and leaned back in the tube as she recovered from her intense orgasm.

"I love you Ayu. I really do…"Cosmos said, kissing the girl's cheek gently.

"Please consider me, as more than just a fan from here on out." she whispers.
