It was then the bathroom stall opened revealing the upperclassman gyaru, Arata Chika.
SOMEONE SAW HER!!!
She screamed in her mind.
Before she could even think of doing anything, Rin's willpower failed her and she came hard. Rope after rope of clear cum splattered over the confused gyaru's face and body.
As Rin slumped back onto the toilet she let out a whimper, "My life is ruined~" she couldn't help but feel aroused at that for some reason.
The girl she had just plastered with cum simply dipped her finger in the fluid that gathered in her generous cleavage, "Did you like just squirt all over me?"
Rin couldn't muster a word as an orgasm still rocked her body.
Arata-senpai leaned forward, "Wow your clit is big… wait is that a dick?"
The gyaru crouched down giving Rin a view of her thong eating into her crotch. Rin's tiny penis jumped up at the sight.
"Wow, it is! And it's soooo small and cute. Like a little kid," the girl then poked it with a manicured finger causing it to spurt a bit of precum, "Hehehe, it likes me. But I didn't know you were a boy Tohsaka-chan?" she then lifted up her small balls, "Wait you even have a pussy under your cute tiny balls! I didn't know you can have both!"
Rin felt her pride sting as the older girl kept mentioning how small her penis was… but she got harder as she kept it up!
What is wrong with her?!
Arata-senpai looked up at her, "Ne, Tohsaka-chan did you run to the bathroom to tug on your little clit dick like the other boys?"
Arata-senpais's words made her penis let out a spurt of precum and Rin then hid her face with her hands embarrassed as the older girl was correct.
The gyaru giggled as she kept toying with her penis, "Hehe, I figured. Fujimura-sensei awoke her womanly charms last summer and it made all the boys act like horny monkeys. Well I guess you too," she then blew gently on her penis making her hips buck, "Wooow, it's so sensitive. I kind of want to eat you up Tohsaka-chan."
Rin gulped at the hungry look in the gyaru's eyes.
"We don't have time for too much fun but let me give you a little service now and a full course later. How does that sound cutie?"
Rin couldn't help but nod.
The gyaru gave her a cheeky smile, "Good. Now I'm going to tug on your little clitty dick until you spurt a big one, okay?"
The girl's current languid pace sped up and Rin shuddered from the feeling.
"You are totes cute Tohsaka-chan. I really want to gobble you up now… maybe a little taste."
The girl leaned down and gave her small balls a kiss, "They are so tiny!"
Rin's penis spurt out more precum.
The girl gained a devious look, "Oh, do you like it when I mention how small you are? Your tiny little clitty dick and your little baby balls are so cute! I've seen little boys who are bigger than you!"
Rin's mind blanked and she came hard as an earth-shattering orgasm ripped through her body at the girl's insults, "I- I'm Cumming Arata-senpai!!"
Her pussy gushed and splattered the toilet seat with her juices. Her penis which was about to shoot ropes of cum was stopped by Arata-senpai clamping down on it.
She grunted in a mix of pain and pleasure as her orgasm was denied.
"Oh, don't want to make a mess!" The gyaru quickly aimed her penis at her mouth and released her hold on her. Rope after thin watery rope spurted into the girl's waiting mouth.
Rin let out a satisfied moan and fell back onto the toilet.
Arata-senpai swished her cum around in her mouth and then swallowed, "You know not bad. I mean I can't really taste anything… but still I kind of prefer the thick stuff more ya know?"
Rin couldn't respond as she still rode on the aftershocks of her orgasm. Why did it feel so good?!
"Looks like you are a bit tuckered out. It's always so cute when guys get like that."
Arata-senpai then patted her head. That made her feel nice.
She then leaned in and whispered, "So Tohsaka-chan why don't you come with me after school? I'll make you ~ feel ~ really ~ gooood~"
Rin made a small noise of agreement. She wanted more, much more.
The girl stood back up and smiled, "Good! Why don't you meet me at that new cafe that opened up?"
Rin managed to regain enough of her wits to think and said, "S-sure."
"Good! Well, bye-bye Tohsaka-chan!"
Rin sat there for a few moments, mind still spinning.
Rin eventually managed to drag herself off the toilet and got cleaned up… but her… clit dick as Arata-senpai called it was still hard in anticipation.
Rin gulped as she knew the next few hours would be rough.
***
Rin speed walked out of school the second the bell rang and quickly made her way to the new cafe.
She may have gotten there too early as she had to wait nearly half an hour till Arata-senpai showed up. The cup of coffee she had helped settle her nerves and made her reconsider the whole affair entirely… but that was when the bell jingled and Rin looked up to see it was Arata-senpai at the front of the store.
It seemed there was no backing out now.
She waved down the girl and the upperclassmen sat down at the table with an apologetic expression, "Sorry Tohsaka-chan! One of my friends wanted a bit of help."
Rin looked up at the girl and noticed a stray hair in her cleavage.
It was that kind of help.
Rin felt her penis harden.
She waved the girl off with a flush, "It's no problem Arata-senpai."
"Hehe, he can be a bit of a more than handful at times but I like it," her eyes sharpened in amusement, "Now Tohsaka-chan do you want my help too~?"
Rin gulped as her thoughts spiraled back to the bathroom. She had felt so good and she wanted to feel that again.
She wet her lips, "Y-yes. If you don't mind."
Arata-senpai brought her hands together, "Nice! Let me just get a drink and we can go."
With her drink in hand, Arata-senpai led her through the city and soon they arrived at… a love hotel.
She knew it was coming but she couldn't stop the way her heart hammered in her chest as she walked into the hotel.
What if someone recognized her?!
That thought only made her more aroused.
Arata-senpai got their room with a certain familiarity. How often did she come here?
The older girl led them to a room and… it looked like a regular room for the most part.
Arata-senpai whispered into her ear, "I just got us a normal room, nothing fancy. So are ~ you ~ ready?"
Rin nodded and her senpai then told her to strip.
"Come on Tohsaka-chan, Strip! Don't want to get your clothes dirty. Even if it makes walking around town a bit exciting~"
Rin slowly and reluctantly stripped. Now she stood fully nude cupping her privates.
Arata-senpai walked around her, observing her, "Woow, Tohsaka-chan you are beautiful you know that? Your thighs are so nice and plump," she squeezed her thighs and Rin shivered, "And your butt is so nice and firm. Do you work out a lot?" she asked while she gripped her butt in her hands.
"Yes. I do martial arts," she replied with a shiver as the girl ran her hands across her body.
"I can tell now that I got a closer look," her hands traced the muscles of her back and then she groped her breasts, "And these ain't bad either!"
Rin made a squeak of surprise at the sudden molestation.
The girl then tweaked her nipples, "Just look at these cute pink nipples, I could tease them all day!"
Rin jolted, "Ah!"
"Oh, you have quite the sensitive pair, how cute."
Arata-senpai then nibbled on her ear, "While I could spend all day rubbing you up and down… what I'm here for is between your legs Tohsaka-chan~"
Her hand traveled down Rin's body and reached her own which covered her privates.
"Open up for senpai~"
Rin slowly uncovered her penis and showed that it was at full hardness leaking a steady stream of precum.
"That's what I wanted to see Tohsaka-chan. Your cute little dicky."
Rin's hips bucked slightly and shot a lance of precum across the floor.
"For being so small you sure make a big mess, huh? Why don't we fix that?"
She heard the girl rifle around her pockets and then she presented a… condom, "Tadah! Now we are going to wrap you tiny shooter up in this so you don't make a mess okay?"
The girl opened the packaging revealing a bright pink condom, "I like getting the colored ones because they are super cute!"
She then rolled it on… or well attempted to as it slid off.
"Sorry Tohsaka-chan you're a bit too small and I only have that size on me… Oh! I have a good idea!"
The girl pulled out a hair tie, "Let's make it nice and snug with this!"
She put the condom back on and at the base of her penis making sure it stayed there with the use of her hair tie. The tie bit down on her dick making the veins bulge outward.
"There we go! Now let me make you feel really good."
Arata-senpai gripped her penis with her fingers again and begin to jerk her off. Even with the condom muting the feeling, it still felt great.
"And as a little extra service~"
The gyaru tweaked and tugged one of her nipples.
"Ah!" shouted Rin as she bucked her hips.
"Cum for senpai Tohsaka-chan~!" she said as she nibbled on her ear.
Rin bucked her hips and came. The condom distended briefly from the force and filled a fair bit.
"You shoot pretty hard don't ya? I want to see you shoot more and more!"
She jerked and teased her over and over again. She ended up filling the condom with 5 loads leaving it a bloated gravid balloon.
"Wooow. you came so much. I mean it's clear but still, that's super impressive! Though some old guys I know can do this in one shot and it's super duper thick and tasty. But for your tiny little balls to try so hard is super cute!"
Rin couldn't form words as she was so overstimulated but her body responded to Arata-senpais's words as her erection still stood.
"Still raring to go how adorable! You might be super small but you got almost as much stamina as some old guys I know!"
"Now, why don't you get on the bed on your hands and knees for me? This next part will feel super good!"
Rin breathed heavily with exertion. In her haze of lust, her senpai's words sound wonderful. She said it would feel good right? So might as well.
She shakily climbed onto the bed and presented her butt to her senpai like an animal.
She felt her senpai get on the bed, "Ready for round two Tohsaka-chan?"
Rin just wiggled her butt.
Arata-senpai gave it a light slap sending a jolt through her body and making her cum.
"You like that?"
Rin wiggled her butt once again unconsciously and her senpai said, "I'm about to have some fun milking you~!"
She slipped another condom on and like before tied it off making Rin grunt in pleasure.
Arata-senpai's grip felt different as she jerked her tiny penis… it was like she was milking a cow.
It felt really good.
"Mhmm… I got a nice view of your wet cunt from here Tohsaka-chan. It's such a pretty pink color and it is absolutely gushing! Let me get a little taste."
The second her lips touched her lower ones Rin came spraying her useless watery seed into the condom. When her tongue went in she came again. Arata-senpai dug in and wiggled her tongue in so many pleasurable ways while she milked her little dicklet.
With a lewd,*pop* Arata stopped eating out her pussy, "Ha! You taste delicious Tohska-chan! And you came so much!"
Rin's eyes were clouded over from the sheer pleasure she was experiencing. But she could still feel the weight hanging from her still hard clit dick.
She then felt the weight disappear and Arata-senpai rolled her over.
With hazy vision she watched her drink down her watery cum, "It's a little thicker than earlier Tohsaka-chan. Maybe if we keep going your little balls will drop and you can cum a big girl load that might actually get someone pregnant."
Pregnant… her heart hammered and her little dick twitched into full attention.
Arata-senpai narrowed her eyes amused, "You like that Tohsaka-chan. Do you want to get me pregnant, with your little baby dick?"
Rin simply bucked her hips in response as her higher thought processes had long since shut down in favor of more animalistic instincts.
"How cute!"
Her senpai then straddled her and rubbed her thong-covered pussy against her tiny dick. Rin bucked her hips against the thin cloth smearing it with her precum.
"Mhm… so ferocious," muttered her senpai with a light blush.
She leaned down and teased her nipples, "Do you want to lose your virginity Rin-chan?"
Rin responded by splattering her clear cum all over her thong-clad pussy.
"I'll take that as a yes!"
Her senpai slid her now soiled garment letting Rin see her clean-shaven pussy but before she could thrust herself into the warm hole she was stopped by a hand pushing down on her.
"I'll let you go wild in a minute Rin-chan. Just let me make sure you are in the right hole first."
She lined up her tiny length and dropped her hips. Rin instantly began to pump her hips with as much strength that she could muster.
"Ahn~! Your so forceful~!"
Rin kept thrusting while her senpai's massive tits jiggled in front of her face.
She wanted these tits to leak milk.
She wanted to make her pregnant!
Rin with strength that did not match her size pushed her senpai down roughly into a missionary position.
Her senpai shouted in surprise.
Rin then pistoned in and out of her with all her strength grinding in as deep as she could whenever she slammed down.
Her senpai moaned loudly, "Ah, such an intense mating press!!! Even with your tiny dick, it feels so goood~!!"
Rin felt a big one building up as she slammed her hips down with great force.
Her senpai then pulled her in for a kiss. When she released her she simply said, "Breed me Rin."
Rin felt her little balls go into overdrive hearing that and she slammed down one last time cumming with all her might.
Her seed exploded from her tip with such force it reached the deepest part of her senpai's pussy.
Her senpai moaned loudly, "I can feel it in my womb! I'm Cumming!!"
Her senpai's fluids sprayed out.
She did that. Rin felt a bit of pride and promptly collapsed on her senpai's chest finally spent with that final load.
Her senpai reached down and tugged on her flagging erection, "Looks like you are finally out," she brought up a finger that wasn't coated in her watery useless cum. No, it was covered in a thick pearly white seed.
"Looks like your a big girl now Rin-chan," she brought her in for a kiss, "My big girl."
Rin felt her mind return to some semblance of normality now that her wild animalistic urges were sated.
And she felt… content.
She just wanted to do this forever.
She didn't care about school, her magecraft, or even the grail war anymore. She just wanted to be with her senpai.
***
Rin quickly focused, there would be time later for her to admonish herself for her actions. At the moment she had to… hide said deplorable actions.
It made her feel sick to use her magecraft to hide her crime… but as much as she hates to acknowledge it… she felt a bit aroused as well. The complete control she felt was exhilarating.
Those thoughts in turn made her feel worse.
There truly was something wrong with her. Was it the penis… or was it simply her true desires? Was she just a degenerate deep down?
She quickly snapped out of those thoughts, lest someone else entered the bathroom and discovered her shame.
A plan quickly formed in her oddly clear mind. She projected a bucket and after making sure the bathroom was empty filled it with water and dumped it on Arata-senpai.
The water drenched her clothes and hid the stains of her watery cum.
Rin took a moment to stare as Arata-senpais's clothes tightly hugged against her skin.
She licked her lips as she felt her penis stir slightly.
She quickly shook off her growing arousal and undid the hypnosis, lest she is tempted further.
The girl slowly roused with her long eyelashes fluttering open.
"Arata-senpai. Are you okay?" She asked.
"What happened?" She groaned out.
"Someone left a bucket of water on top of one of the stalls."
Please believe it!
Arata-senpai then let out a moan of annoyance, "Ugh, I fell for that old trick. Like seriously."
She then looked down at her soaked clothes, "Gross I'm all sticky," she lifted her shirt and gave it a sniff, and made a face, "What did they put in this?"
Rin's heart raced at the sight. Was she going to be found out!?
The girl shook it off, "Well whatever, I have my gym clothes in my bag anyway."
Her heart calmed.
Arata-senpai stood up, grabbed her bag near the entrance, and rummaged through it. She then pulled out her gym uniform and promptly stripped.
Rin gulped at the sight of Arata-senpais's bare flesh. She could not deny that her senpai had a gifted body. Rin stared at her breasts for a moment. It looked like her lacy bra struggled to contain the mounds. Her eyes traveled lower to her generous hips and finally to the thing that could not be ignored, her senpai's massive ass. Rin's eyes could not be torn from the sight of Arata-senapi's underwear being devoured by her ass.
Did she have no shame!?
Arata-senpai turned around and looked amused once she noticed her staring.
She said in a teasing tone, "Eh, what's wrong Tohsaka-chan? You're staring rather hard~ I know I've seen you staring at Emiya-kun a lot. So do you like both~?"
Rin turned away embarrassed, someone saw her!
Arata-senpai let out a teasing laugh, "Hehehe, Your so cute Tohsaka-chan. There's nothing wrong with like both you know?"
Rin's eyes looked back and saw that Arata-senpai was wiping herself down with wet wipes.
"Always good to have these on hand, ya know?" she said as she wiped her breasts.
Rin gulped once more and looked away again. She could feel her penis tenting her panties.
A few minutes later she heard, "Alright all done!"
Arata-senpai was now dressed in her gym clothes. She had recently discovered that she found them rather… erotic for some odd reason. That may have been the result of ogling the track team for a bit.
She really was a degenerate, wasn't she?
"Thank you for staying with me Tohsaka-chan! Now, why don't I give you a little service~"
Arata-senpai then buried Rin's head into her breasts.
They were… soft. Rin didn't even attempt to struggle out of her grasp… something about Arata-senpai made her relax for some reason.
Her senpai pat her head and released her after a moment.
"I'll see you later Tohsaka-chan!" she then strutted out of the restroom and Rin couldn't keep her eyes off of her ass.
She looked back to the stall and down to her slightly tented skirt. It wasn't really that noticeable… but if she was going to be more proactive in managing her desires then she better start now.
She shuffled back into the stall intending to relieve herself with thoughts about Arata-senpai's ass.
She dropped both her panties and skirt and let her small penis spring outward into the air. Despite cumming so many times already it still was able to get hard. At least she had that going for her to make up for her size.
She gripped her penis with her index and thumb and found it was still slick with Arata-senpai's saliva. She quickly shook her hand up and down while she let her mind wander. Specifically about Arata-senpai's ass.
Not even a minute later she felt her orgasm build up. She thrust her hips and let out a shuddering breath as her watery cum spurt into the toilet. The feeling of orgasm wasn't as powerful as before… but it still felt really good.
With a sigh, she hiked up her panties and skirt feeling much better.
She should be able to make it the rest of the day now.
Rin sat in her workshop potion in one hand grimoire in the other. She was debating about what to do. She had committed a crime. She raped someone with her magecraft.
The idea still excited her and she hated it.
She eyed the potion bottle. All she had to do was drink it and her penis would be gone… but she went to so much trouble to gather the ingredients.
So much money was spent and if she takes this potion now it would have been a huge waste.
In the end, her magus mentality and frugal nature overrode her morality. She placed the potion back into its secure spot and opened the grimoire flipping to the bookmarked page.
The jewel studding ritual. She reviewed the information and committed it to memory. She cleared a part of her workshop knowing that it may get… messy. It was a precaution after she experienced the effects of the potion. She also projected and laid out a plastic tarp just to make sure.
She then pulled out her pendant. In her opinion, it was the best choice to use. She had been filling it with her magical energy for roughly ten years and its quality and energy storage were simply top-class. So the chances of rejection should be low. It should also kickstart her magical energy generation by a significant amount.
She removed the one-of-a-kind jewel from its setting and laid it on a carefully drawn circle. It still felt a bit like desecrating her father's memory to use this jewel in such a way but it was the best jewel she had access to and the ritual recommended using only quality jewels less there would be undesirable side effects.
She turned on her circuits and went through the process of inscribing the spell onto the jewel.
The first part of the spell. Gathering magical energy. It was simple enough.
The outer portion of the circle lit up and engraved itself within the jewel.
The next part of the spell was one of the more important parts. It would convert a portion of the stored energy into pure vitality that would then slowly leak out of the jewel into the body. This would nurture the body and encourage it to generate more energy. That energy would then be gathered by the jewel and the process would begin again but more potent.
A feedback loop and simply genius.
The middle section of the circle lit up with complex spell formulas and engraved itself within the jewel.
She wondered if her father would have used the method… No, he wouldn't now that she thought about it. It would be considered too vulgar for a proper magus to use.
She, however, had little choice.
She continued on to the final part of the spell. Power transferal. It would allow her to draw on the stored magical energy for her personal use and transfer some of the stored energy directly into another jewel. The direct transfer would likely not be the most efficient but would help in a pinch if she wanted to make a few potent disposable jewels.
The inner and final portion of the circle lit up and engraved itself within the jewel.
The jewel lit up as the spell settled within it. She held it up and could already feel it leaking vitality. It made her hand feel rather warm and a few aches and pains she didn't notice faded.
Useful.
But she didn't need it leaking energy at the moment so with a small prod of her magical energy that portion of the spell switched off.
Now for the next part.
She stripped and stood on the tarp.
This next part… may hurt a bit. She was a bit thankful the only magecraft Kirei was actually good at was healing as it will come in handy in just a moment. She tapped her penis and muttered a local anesthesia spell numbing the organ.
That should dull the pain.
She then laid the jewel on the base of her penis and muttered, "Here goes nothing."
It was time to bind the jewel to the flesh.
She spoke the spell through grit teeth as the process was painful despite the area being numb.
Thankfully it was over rather quickly. She looked down at her penis and her family's prized jewel gleamed proudly as it was embedded into the organ. The jewel was almost a tad too large to fit as her thin girth barely accommodated it.
Hopefully, that would change soon.
She then turned on the spell and shuddered as her penis felt warm. The jewel glowed and engorged veins bulged outward. They pulsed powerfully as pure vitality spilled into her penis and testicles.
Her male organs throbbed and she collapsed to her knees in pleasure. With each beat of her heart, her penis pulsed and grew just a bit longer and a tad fatter. She felt her balls churn and grow in her sack stretching it to accommodate the growing orbs.
With one more mighty beat of her heart, her organs pulsed powerfully and she bucked her hips and came hard. The first rope was thin and watery. The next was a milky white. The next is a bit thicker and whiter. And the final rope of cum was glue-like in its consistency and color.
Rin let out heavy breaths and looked down at her penis. It was much bigger and no longer looked like it belonged to a child. It was a proper adult penis… that throbbed powerfully with need.
Well, she already made a mess so might as well, right?
She gripped her new penis. Not with two fingers but with a full fist. She smirked feeling a bit of pride in her newly enlarged organ.
Now to relieve some pressure.
She slid her hand up and down slowly at first but picked up the pace as she began to relish the pleasure.
She quickly achieved orgasm and let out rope after rope of thick white seed. It landed heavily on the tarp and collected in small pools.
Rin had a small smile on her face as she looked at her now potent seed.
She then looked down at her still throbbing length.
Well a little more couldn't hurt, right?
She continued to pump out at least half a dozen more loads before she stopped herself.
The tarp she laid out was covered in strings and pools of thick gooey semen.
Rin never noticed that the following pages of the grimoire were stuck shut by a sticky substance. Said pages held an important warning.
Do not use more than one jewel. Regularly drain energy from the jewel.
A heavily charged jewel may cause side effects.
Side effects include:
Excessive growth in the penis and testicles
Discoloration of the penis and testicles
Abnormal growths on the penis
Excessive Smegma production
Excessive Semen production
Abnormal Semen consistency and potency
Massively increased Libido
Lowered Inhibitions
Increased Sexual Aggression
