Tohsaka Rin Vs the world (3)

Rin lay on the floor of her workshop feeling an odd mix of exhausted yet energized. The exhaustion was more than likely due to her… vigorous draining of her still churning testicles. She still felt the near-molten lust boiling between her legs and it called for her to spurt, spurt, and spurt some more. She was so very tempted to give in but she only stopped because the rest of her body couldn't quite keep up with her now ravenous libido.

She imagined it will catch up in the coming days, however. As she could feel pure vitality leaking into her body. Nursihing it and making it more… vigorous. Her exhaustion was slowly fading away and she had things to do. So she peeled herself off the cool floor of her workshop and looked at the mess she caused.

It was like someone threw multiple tubs of glue around with how thick and white her seed was. She still felt a bit good about that. After shooting watery ropes she felt a bit… pathetic. As if all her superior breeding amounted to was a pathetic baby dick that couldn't hope to knock up a woman with the useless seed it produced.

Now though? She felt good. While her newly grown penis wasn't massive it was better than that little nub she had before. And her semen! It was thick, white, and potent.

She wanted so badly to plaster her Senpai with it. Rope after rope of jelly-like cum would frame her face. It would drip down into her cleavage and pool in between the soft jugs.

Rin felt her newly enlarged genitals throb slightly. She then shook her head of those thoughts and took another look at the mess she made. Thankfully her projected tarp caught the brunt of her… emissions leaving only a small part of her workshop sullied with her seed.

She breathed in and recoiled slightly from the stench of her semen. Now that she was out of her haze she could acknowledge it.

… She for some reason couldn't hate it. It even aroused her slightly. It was as if she marked that this was her territory with the scent of her potent seed.

She pushed that thought to the back of her head and gathered the tarp. She brought the edges together and watched as her semen slowly collected within the center. The thick globs took their time to travel down and when the bulk of it settled she furrowed her brow. She could feel a good bit of magical energy within the goop.

It would be a waste to simply throw it out but what to do with it? She then eyed a few of her lesser jewels that she had yet to charge.

Could she?

She grabbed a glass jar and held the tarp above it. With a thought, the projection dispersed leaving her magically charged seed to fall into the jar… mostly. A bit splattered near her feet but the bulk of the slop ended in its intended location.

The large jar was about a quarter filled with her seed. That was… quite a bit she believed. If she remembered correctly the average male produced only a tablespoon of semen per ejaculation. The jar looked to be filled with far more than twelve or so tablespoons.

It appeared she could submerge her jewels easily and so she plopped a few of her jewels within the genetic soup and slowly but surely the jewels began to charge unprompted. She hadn't even started the transferal process yet!

A side effect of her stud?

Perhaps her seed took on some of the transferal properties from the spell.

It wasn't a bad side effect. In fact, it was a good one. Most bodily fluids held that property in some measure with blood being the strongest. Which is why it has been her go-to method to charge her jewels. Hours of her day were usually dedicated to drawing her own blood and slowly transferring the power within to her jewels but if her semen was now better than that?

She could free up much more time to practice her magecraft.

Maybe she will keep her new organs around after all. Time is something you couldn't get back… well you could but that was another branch of magecraft entirely.

Now she just needed a good way to store her semen.

That would be… condoms.

She will buy them after school and make sure the clerk has no memory of ever selling them to her.

… or maybe she makes a disguise? She shouldn't be so trigger-happy with hypnosis after all.

When she finished cleaning up she took a look at the clock and if what it said was right she had been… relieving herself for a few hours. Hours she was supposed to be sleeping.

Rin simply sighed and went to clean herself up. When she left her workshop she realized she was still parading about in her birthday suit.

Her heart hammered in her chest as she stood nude in her own home. Her penis throbbed as she felt excited.

A little walk won't hurt. The only other person at home was her mother and it wasn't like she would do anything about it.

She then strutted to her bathroom penis bouncing up and down along the way.

It was her home and she could do what she wanted. If that meant walking around in the buff so be it!

She couldn't hide the odd smile that found its way to her face.

She entered the bath and looked down at her throbbing length.

Maybe one more time.

Rin let out a sigh of relief as she exited the bath. She may have relived herself a bit more than one time but it was something she had to do! She didn't want a repeat of the bathroom incident after all.

Rin stretched and yawned as she felt tired. She then adjusted her penis as it was just a tad uncomfortable being trapped in the confines of her panties.

She just knew she will have a bit of trouble tomorrow. It was easier to hide her little nub but her newly enlarged member may bit a bit obvious. Depending on how it went she would rig some minor mystic code so people won't notice it.

She then looked at the time once more and decided to check up on her mother. Thankfully she had been getting better in the past few years and wasn't a complete invalid… she just wasn't there. So that meant while she could roughly take care of herself she still had to be cared for.

She peered into her bedroom and saw her splayed out on her bed. It looked like she kicked off her blanket during the night.

Rin walked over and went to tuck her back in… but paused as her eyes were glued to her mother's breasts that slipped out of her nightgown. They were so… big! Were they always that big?

Rin knew her mother put on a bit of weight… but she never really paid attention to where she put on weight.

Rin took another look at her mother and felt she hadn't really looked at her properly in the past few years. Her mother had never been that curvy to her memory but now? The image of her mother within her mind cracked as Rin's eyes drank in the sight of her mother's plump flesh.

Large breasts held darkened areola and rather prominent nipples. The signs of motherhood and breastfeeding were obvious.

Her eyes traveled a bit lower past her mother's chubby belly and to her wide hips. They then went a bit lower and she saw her mother's hairy mound.

Rin gulped as she felt her penis harden and strain within her panties. She could already feel her precum soaking into the fabric.

With a force of will she tucked her mother in and quickly left the room.

Rin gritted her teeth as she leaned against a wall. Despite cumming so much she still felt her penis throb with need. She let out a shuddering breath and forcibly calmed herself.

She drew the line at masturbating to thoughts of her mother.

She went to bed and promptly passed out.

Rin's dreams were plagued with thoughts of her mother and she woke to semen-soaked pajama pants. And it wasn't the only thing ruined as her blanket and sheets were plastered with semen.

This is going to be a problem.

Maybe she could wear condoms to bed if her… night emissions are going to be this messy. That and it was a waste of magical energy that could be better used to charge her jewels.

Buying condoms just went up in priority.

She slid out of the soaked pajama pants and panties. She made a face as they dripped with her semen. She then collected her blankets and sheets. After putting on a pair of clean pajama bottoms she started a load of laundry to clean the defiled fabrics.

With that, she started her daily ritual… which included a few new additions. One such addition was cleaning her foreskin. After yesterday she recalled that little bit of information about foreskin… after her Senpai cleaned her. She was a hygienic girl and she refused to let her body build up that filth.

The next was… to ejaculate a few times into the jar that held her jewels. She never wanted another incident like yesterday. So she will make an effort to manage her libido… which seemed to have been kicked up a notch or so.

Her arms may be getting a bit of a workout in the future but at the same time, she will have a bit more firepower to throw around.

After she finished her breakfast she prepared for school.

Hopefully, it would go well.

Her day at school did not go well at all. If anything her previous problems got kicked up a notch! She caught herself staring at the girls more and more. She even had to take a few bathroom breaks to ease her lust!

And Taiga Sensei was not remotely helpful! The woman seemed to ramp up her teasing of the boys (and as a byproduct, her) after yesterday's incident. Showing off that big ass of hers. The damn tease!

She had to make up an excuse that she had bad takeout the night before so she could go and jerk out a load!

It was so terribly embarrassing!

But thankfully the day came to an end.

And so she prepared to buy… condoms.

She already had a plan for that little problem of hers.

Rin ducked into a public restroom and a few minutes later a young feminine man stepped out.

She did her hair up in a ponytail. Put on a black cap and face mask to hide her facial features. She had bound her breasts so they appeared completely flat (not much effort was needed and that irritated her a bit). Her clothes were replaced by a simple tracksuit.

As Rin looked in the mirror she realized she looked… sketchy, but relatively unrecognizable. So she put on the final touch. She held a hand to her throat and hummed. With a little magecraft, her voice dropped a few octaves till it sounded masculine.

"There we go," she said with her new voice.

She then realized she was in the women's bathroom.

She made a quick exit and thankfully didn't run into anyone.

Rin felt herself blush as she set the boxes of condoms on the counter. The young cashier gave her a raised eyebrow as they scanned her items.

The young man asked, "Going to have a fun night?"

She felt her eye twitch. Why is he getting so chummy? Is this normal?

Despite her confusion, she replied anyway… with a hidden arrogant smirk that reached her eyes, "Yeah just a bit."

The young cashier looked a bit surprised at her voice. Probably thought she was a woman… which was correct… for the most part. Her new set of equipment made that a bit muddled. She did enjoy his flustered expression though.

He coughed into his fist, "Ah, I hope you have fun dude. That will be…"

He then rattled out the price and she grumbled as she pulled out the needed bills. While chump change in comparison to the money she threw around for jewels. She just knew that it was going to become a necessary expense in the future.

Still didn't mean she can complain about it.

The condoms proved useful Rin found. Throughout the week they made her life a bit easier.

As an example, her morning routine had a new addition. Pulling the semen-bloated condom off her penis and dropping her jewels into the thick soup of her nightly emissions. That particular batch of seed was especially filled with magical energy and was perfect for her main set of jewels. She just had to fish them out when she got home.

The next was making relieving herself at school easier… although hiding the filled condoms proved to be a slight challenge. As they were… rather full and were a bit of a pain to store. She had taken to bringing a spare thermos and using that as a receptacle for them.

The reason she didn't just leave them in the trash? She wanted to make use of the magical energy within them.

Which brought her to her new routine. Dumping the contents of her filled condoms into a large jar of jewels. Said jar was getting quite full. She was going to need either another jar or a bigger container.

The only problem was whenever she removed the cork of the jar she was blasted with the stench of semen. Addmitily it aroused her… just a bit.

Her new method of charging her jewels was rather effective she found. She even had new ideas! Before she always looked out for the best of the best in her jewels. To get the most bang for her buck as they say. The primary reason was that charging them was a task and a half but with this new method, she could charge many jewels at once. That meant she could use many lower-quality and more importantly cheaper jewels to practice her magecraft.

Now small accidents didn't mean a small fortune being lost! Now she could save up for the real quality jewels.

Maybe she could find more good jewels to stud with.

***

Rin prepared to head to school but made a quick detour to her bedroom to grab some condoms for the day. When she reached inside the box she found… one.

She held her last condom in her hand with disbelief. She needed at least five to make it through the day! She made too much of a mess now not to use them!

Did she have time to buy more?

She eyed the clock and realized she did not have the time to change into her disguise and buy more.

That meant she had to make do with her last condom.

Rin grumbled and stuffed the condom into her pocket.

She will figure something out.

But first, she applied her self-hypnosis. Didn't want any surprise erections giving her away now did she?

Rin bounced her leg up and down as she felt the roiling lust grow within her. Her method of concealing her new package definitely didn't help. While her self-hypnosis prevented her from getting an erection it did little to prevent lustful thoughts from cropping up. In fact that only made her erections worse when she released the hypnosis! Her penis pulsed with such power and need that she was a slave to her desire to shoot out her seed. It generally reached a boiling point about three or so times a day. Once in the morning, during lunch, and near the end of the school day.

Her little schedule was to excuse herself to the restroom in the morning to jerk out a quick load. During lunch, she would milk out three or so loads. The amount depended on if Taiga Sensei was feeling like a tease that day. Then near the end of the day, she would drain her balls in school restrooms a final time.

She had grown a bit used to the schedule in the past four days. She may have also gotten a bit too comfortable relieving herself in school… but she did find it a bit exciting and that served to make her cum faster.

The thrill of jerking herself off in public was quite exhilarating.

She however couldn't drain herself this morning as she only had a single condom to her name. As she was waiting for lunch to thoroughly drain herself.

Lunch was currently a bust since she was caught by Mitsuzuri.

She sat across the girl while she rambled about something or another and the only thing she could focus on was wanting to stroke her meat. While Mitsuzuri was a friend, her mind was too clouded by lust to pay proper attention.

"Hey, Rin!"

Rin snapped out of her haze and looked up at Mitsuzuri, "Y-yes?"

Her friend furrowed her brows in worry, "Are you okay? These past two weeks you've been a bit… distant."

Rin blinked and then realized she had been a bit more closed off. Which was more than likely caused by her newly grown organ influencing her life.

She needed an excuse… ah! That could work. It was even a bit true and the best lies often held a grain of truth.

Now she felt bad as she decided to lie to her friend. She then quashed that feeling with her magus mindset. It was necessary for a magus to lie after all.

She wet her lips and slowly said, "My… my mother is over right now. So I've been taking care of her. It can get… rough at times."

Mitsuzuri then slowly placed a hand on her shoulder, "You've told me about her condition before so I get it. Sorry I brought it up."

"It's no problem," Rin then glanced at a nearby clock. She had just enough time to milk out a load if she left now. She turned to her friend, "Do you mind if I go to the bathroom?"

Mitsuzuri drew back her arm, "Ah! Go ahead. I'll see you in the next class anyway."

She gave her friend a polite smile as she gathered her things. When she was out of side she quickened her pace. She so desperately wanted to cum. As she approached the stairwell she paused as she heard a conversation.

"You have got to try this thing out, dude! My brother gave me the instructions before he left for college and it's the best thing ever! Super easy to make too!" said a male voice.

"Really?" asked another male voice.

"Yes, dude. It feels way better than your hand."

… Were they talking about masturbation? Rin got a bit curious and leaned against the wall. After all to her lust-addled mind, something that made masturbation better was of interest to her.

"Just write it down and I'll try it out later."

"Yeah give me a second."

She then heard the scribbling of pen on paper. When she heard him tear out the page she stepped out of the corner and the boy dropped the paper in surprise.

It then fell down the stairwell. Perfect.

"Tohsaka! …Did you hear?" asked the frightened boy.

She raised a delicate brow and said cooly, "Hear what? Now if you will excuse me I have somewhere to be."

She walked down the stairs and the boys ran off clearly relieved that she hadn't overheard their convection, even though that was a lie. She then bent down and picked up the page.

Potato starch X?

She quickly read the instructions to making… an onahole.

Her penis throbbed slightly somehow overcoming her self-hypnosis.

She stuffed the paper into her bag and hurried to the bathroom… but the ringing of the bell signaled her doom.

Her brow twitched and she reluctantly headed to class… after making sure her self-hypnosis was reapplied.

Rin felt like she was going to explode or rather she felt like her balls were going to explode. She was not able to find any time to relieve herself at school today. Her current state was only salvageable thanks to her gaining a few interesting things throughout the day. One was the recipe for the Potato Starch X and the other? Several illicit magazines she got from the disciplinary committee room.

She was asked to dispose of them as she was a model student and was deemed responsible enough to do so, normally that would be the case. Rin however had gained a new outlook on such things. So rather than disposing of them normally by throwing them in the burnable trash… she simply took them for herself.

So when the bell rang for the end of the day she nearly ran out of the school. She needed to relieve some pressure or she was going to go crazy. She didn't even make it out of the gate before she felt her self-hypnosis unravel as her lust reached a crescendo. Her body demanded relief and she could no longer ignore the siren's call of shooting out her seed.

So she ducked into the woods near the school. Her mind and body were so dominated by her arousal she no longer cared if she was outside.

With every step she took, her penis left a trail of precum that dripped from the tent it made from her skirt.

Once she made it a fair distance from anywhere she dropped her panties and observed her throbbing member. It looked angry as the veins near her stud pulsed powerfully.

She ripped her last condom out of its wrapper and rolled it onto her pulsing organ. She let out a pleased moan as she squeezed the base. A spurt of precum more copious than an average male's ejaculation sprayed out and quickly began to fill the reservoir tip.

That thought alone served to make her rock-solid erection harden further.

As she felt a gust of wind she snapped out of her haze slightly.

She was masturbating outside!

And she loved it.

The cloud of lust returned in force and she snaked a hand up her shirt and began to massage her breasts as her other hand almost violently jerked her needy penis.

Her eyes darted around looking for anyone and everyone. The idea of getting caught aroused her beyond belief.

She could no longer deny it, she was a pervert! She was a pervert that got off by jerking off outdoors where anyone could catch her!

Soon enough she felt a big one coming. She collapsed to her knees as a powerful orgasm ripped through her body. Her vagina squirted making a mess of her panties, leggings, and shoes.

She then gritted her teeth as thick ropes spurt out the tip of her penis. The condom sagged lower and lower as it rapidly filled with her backed-up seed.

Rin let out a shuddering breath as her orgasm finally came to an end. She looked at the bulbous end of the condom and she was amazed it held the contents of her balls. The sagging pink latex looked to be the size of a baseball.

On reflex, she pulled off the condom and tied it off. She then held it in her hand and it was rather warm. She looked at her frankly massive load with some astonishment. It looked extremely thick. That's not to say her normal loads aren't, it was just this particular one was very thick. It was almost like porridge in its consistency.

She leaned against a tree and then once the post-orgasm clarity hit her she recoiled in horror.

Oh, the horror wasn't from her little outing, no. it was from how she felt about her little outing.

She enjoyed it. She enjoyed it a lot. More than she would have ever thought possible.

She felt another part of her break ever so slightly.

She then let loose a manic laugh, "Hehehe, I found a new hobby!"

After getting over her little bout of mania Rin eventually cleaned herself up and headed to the store in her disguise. She had a shopping list after all!

Even if it wasn't that much of a list. She just needed condoms, some lube, and a bag of potato starch.

She ignored the cashier giving her a certain look and went on her way.

She really wanted to try out a homemade onahole. She still felt a bit backed up and she had the entire weekend to enjoy herself.

She arrived home and quickly did her duties. Checking in on her mother, throwing her dirty clothes into the wash, and having a quick meal. With all that done she headed to her… kitchen surprisingly enough. She didn't have a microwave in her workshop after all.

The recipe for the Potato Starch X was simple. Mix potato starch with cold water in a bowl. Move the mixture to a cup which she projected as it called to remove it later. Then mix in hot water and microwave till it's clear. Once it was clear she inserted a projected plastic stick that was roughly the size of her penis before it cooled. With that inserted she cooled the cup in an ice bath and then moved it to the fridge.

Now came the hard part… waiting.

She kept herself busy in the meantime. She checked on her mother again, dumped the contents of her condom into the jar, and fished out her main jewels.

She polished them and felt their charge was rather good. With each passing day, her semen charged them better and better. She likely didn't even have to transfer energy out of her stud at this rate. The more it built up the more vitality nourished her body.

That line of thought did make her curious. Would more make the effect more pronounced?

She did have three high-quality jewels reserved from her usual dealer. One of them was going to be her first stud before she decided to use her family jewel.

Well even if she decided not to use them that way she could find another use for them.

She picked up the phone and called her dealer. After a brief conversation and a slightly painful amount of money spent later, she was free to pick up her jewels in the morning.

She leaned back in her comfy chair… and took a nap.

Rin woke up about two hours later with a raging erection. Thankfully she hadn't plastered her panties with semen this time. She got up, stretched, and then realized her onahole should be done.

She rushed to the kitchen a bit giddy.

She removed the cup from the fridge and dispelled her projections. A floppy mass fell into her hand. She inserted a finger into the slit and it made a lewd *Squelch* Rin licked her lips as her penis tented her skirt.

Time to have fun!

As she walked to her room she had another thought.

What if she does it outside?

Her earlier experience was exciting and she already wanted a repeat. That boiling lust between her legs pulsed in agreement.

With her mind made up, she entered her room and gathered her disguise. She was going out tonight!

Rin entered one of the local parks and found it empty… but even then her heart felt like it was about to leap out of her chest. Just thinking about what she was about to do made her beyond excited.

She walked past the public bathrooms and found a nice big bush that could hide her. She then set down her bag.

… It was time.

She let her package flop out into the cool night air and instantly it became rock-hard. Beads of precum leaked profusely from her tip.

She didn't bother with a condom this time. This was strictly for pleasure.

She pulled out her homemade onahole from her bag and poured a bit of lube into the faux orifice.

She then crouched down and held the onahole above her leaking penis. The cool lube dripped onto the already lubricated head of her penis and she let out a hiss of pleasure.

Time for the moment of truth!

She slid the homemade onahole down and as the crown of her penis slid in she moaned, "Fuck!"

She then began to jackhammer her arm up and down as she drowned in the pleasure of the fake hole.

It felt so much better than her hand!

With every loud squish and squelch, she grew more aroused.

She was nearing what would be the first orgasm of many tonight.

As she brought her hand down the bushes rustled and three old men stepped into view.

She Was Caught!!

Her eyes rolled up into her head as she came unbelievably hard. Her semen came out with such force that it punched through the back of her fake onahole and lanced out several feet.

As the orgasm ripped through her body she heard one of the old men whistle out.

"Nice load kid!"

Another of the old men chuckled, "How long has it been since I got distance like that?"

The first old man elbowed him, "Just last week when that girl gave you a rimjob."

"That's right! Hah, that felt great!"

As the two old men talked a bit the final old man narrowed his eyes at her… or more specifically her onahole. With a tone of nostalgia, he said, "Well, well, well. Ain't that a sight for sore eyes? I haven't seen one of them potato starch onaholes in ages."

The first old man muttered, "No shit! Man, that brings me back."

The second old man nodded in agreement, "I made many of them bastards growing up. Got me through many hard times!"

The third old man laughed, "Heh, that they did."

As her orgasm came to an end she looked at the group of old men… that were casually talking. She was so taken aback by the situation she couldn't bring herself to freak out.

The first old man looked at her, "Oh, looks like you're done. Bet that was a big one."

The second old man looked amused, "Definitely a first-timer. I can tell."

The third old man laughed, "Yup! Written all over his face… well what we can see."

The third old man looked thoughtful for a moment and turned to his fellows, "Hey how about we bring him with us?"

The other two old men looked amused.

The first said, "Heh, she's going to ruin him. I'm in!"

The second said, "Me too."

The third walked over and crouched down to her, "So kid. Do you want to try a real pussy?"

Still dazed Rin's lust responded for her as her dick perked back up.

The old man laughed, "I'll take that as a yes! Now pack on up and follow us."

Rin then numbly gathered her things and followed the old men… to a random toilet in the woods?

There was a gathering of men around it and as she got closer she could hear the sounds.

Flesh slapping flesh, wet squelches, and most of all delightful feminine moans.

The third old man motioned for her to get in line, "Well now the boring part, waiting."

A feminine squeal echoed into the night.

The old man gained a lecherous grin and she noticed his pants tent greatly, "But the payout will be worth it!"

Rin still confused by the whole situation stayed silent while she waited in line. Her penis was however diamond-hard.

The line moved at a decent pace as men entered and left the lone stall at a decent pace. Some took longer than others, some shorter than others, but they all left with relaxed satisfied smiles.

Her head cleared enough that she knew exactly what was going on in there.

They were having sex.

She was having second thoughts about the whole thing but soon enough it was her turn. She was however briefly stopped by the third old man.

"Give me a second to clean her up, kid. Want your first time to be special after all!"

She then got terribly embarrassed as a few of the men loitering around clapped and joked around about it being her first time.

What was she doing?

She should just leave… but the idea of losing her virginity was appealing… even if it was to a toilet slut.

… What was she doing with herself?

Before she could think of leaving again the old man popped out and waved her in, "Well here you go, young man. Have fun! Hahahaha!"

Rin stepped in and the sight she saw was something she never expected.

***

Sakura, it was Sakura. There was no mistaking that plum-colored hair, nor the ribbon that fastened it to the side.

It was her sister.

Why was Sakura here?!

She would never do this?!

A more cynical side of her mind then replied.

'Are you sure about that? You never knew her. Maybe she's like you, a pervert. One that gets off on being used.'

Rin shook those thoughts away and tried to make sense of this as quickly as possible. So she defaulted to her magus mindset as her rational side and horny side were of no use at the moment.

If Sakura as a person wouldn't do this, then Sakura the Magus might. It was likely a similar situation to her own. Gathering a stockpile of magical energy for the coming Holy Grail War. Rather than optimizing her own production and quality as Rin did, Sakura took to sheer quantity by gathering it from the masses.

It seemed the two of them were more alike than she thought. Giving up their pride and dignity to get ahead in their craft.

Her lustful side then chimed in.

'Or maybe the two of you are simply perverts.'

She… did not dismiss that thought as a possibility. In the past two weeks, Rin had discovered quite a bit about herself. Such as how far she was willing to go to satisfy her libido.

But at the end of it, her sister was in a toilet and had been having sex with who knows how many men.

Rin's eyes darted around taking in her sister's bound form. The sight was unreasonably arousing. With her big soft breasts, each capped with a pale pink nipple that was unbelievably erect. A primal feeling welled up at the sight of them, she just wanted to pinch and bite them to make her squeal.

Then her eyes went lower to Sakura's gushing hairy hole. It was so inviting as the swollen lips pulsed with need and leaked copious viscous juices.

Her bound limbs only added to Rin's lust. It was as if Sakura was no longer a woman or even a living being… but a toilet. A receptacle for piss and cum. A place to needlessly dump filth.

Rin's penis had never been so hard. Her stud glowed as if in response to her desires. Blood vessels then bulged as blood rushed powerfully into her penis giving the organ an almost inhuman texture with the myriad crisscrossing veins.

Rin's breathing grew heavy as her mind was clouded with desire. She was about to lose her virginity and to her sister at that! That thought only made her more aroused.

Rin felt another part of her break once again.

Rin felt her mouth make a hungry lewd grin underneath her mask. One that she would have never made before, but now felt… natural.

She gripped her diamond-hard penis at the base and beads of precum streamed down from her pisshole.

She liked how that sounded. It was so vulgar.

She already discarded her pride as a magus so what was using crass and vulgar words to her now? Nothing that's what.

She laughed as she thought of her father rolling in his grave about his heir degenerating into a crass lecherous brute.

Rin then took a step and slapped the pink crown of her cock against her sister's sopping-wet hole. She then teased the entrance by smearing her copious precum against the entrance, as if marking her territory.

Sakura squirmed from her light teasing. She looked up at her with a needy face, "Please mess me up already!"

If only Sakura knew she was saying that to her sister.

Rin lined up her cock and leaned in, "Sure thing, Sakura."

Before her Sakura could react, Rin slammed herself into her sister and soon found herself in heaven. It was so delightfully hot and wet. Her sister's folds clung so pleasantly to her shaft and the way the undulated felt so absolutely wonderful.

Sakura's shout of surprise quickly turned into one of pleasure, "Ahn~!"

Rin then felt every once of control leave her. She powerfully, yet unskillfully pistoned her hips as she sawed in and out of Sakura's velvety folds with the power granted from years of martial arts training.

With every thrust, the crown of her dick dug just a little deeper into her sister's pussy.

Rin was momentarily distracted from her thrusting by her sister's bouncing and jiggling tits. With every thrust, they bounced and rippled. She then roughly grabbed them and groped them with jealousy. Why were they so damn big!

She pulled and pinched Sakura's nipples and had to bite her lip as her sister's cunt contracted wonderfully tight.

Her mouth moved out of her control, "Who knew that such a demure girl like you was such a slut!"

Sakura wiggled her hips and the walls of her cunt undulated in a most pleasing way as they tried to milk her.

Sakura looked pleadingly at her, "P-please don't, Ahn~, tell anyone at school!!"

Even in her most lustful moments, she wouldn't betray her sister like that. But even then Rin felt her mind focus on only one thing, her pleasure.

Rin roughly tugged on Sakura's nipples and her sister's pussy grew tighter still.

Rin then grunted as she felt a torrent of cum just waiting to be released, "Just milk this load out of my dick you whore!"

Rin sped up her thrusting and soon enough she felt her testicles clench as her thick semen rose up.

Rin then twisted her sister's nipples as hard as she can while she yelled, "Cumming!!"

She then felt her sister's cunt squeeze her like a vice and she let out a pleased moan as she released her steaming hot semen.

She watched as her sister's stomach bloated just a bit from how much semen she pumped into her and after about a minute she finished. Her softening dick slid out of Sakura's pussy and thick pearly white seed poured out of her.

Rin huffed as clarity returned to her but before she had a moment to think she was pulled out of the toilet as a fat man took her place. She caught sight of the man's penis and it was massive. A moment later she heard Sakura's cries of pleasure… that sounded much louder than what she made with her.

Rin then felt a bit self-conscious.

One of the old men that brought her here patted her on the shoulder, "Don't worry about not stacking up to the rest of us kid. You got a pretty decent tool yourself and you're young anyway so it will get bigger in time. You cum like a racehorse though so you got a bright future."

Rin then looked to the line and saw many of the men rubbing their massive bulges to the sounds of Sakura's moaning.

She knew what she had to do but in the meantime, she had to go home, "Thanks. I guess. I'm going to head on home for the night."

The man then slipped her a card, "If you are still feeling a bit down about your size the best you can do now is get better at using what you got. So if you want to learn a thing or two head here and tell them Kubo sent ya. They will hook you up with some primo 'training' videos."

She took the card slowly, "Sure," she looked at the card and it was to a normal video store oddly enough, "Thanks."

The man patted her on the back, "No problem kid. It's always fun to introduce more people to the pleasures of fucking bitches right! There will always be frustrated women that need some proper loving and we are willing to give it!"

"I… see."

In her post-ejaculation clarity, she found the conversation absolutely strange… but her lustful side roused briefly at the prospect of having more better sex. So she pocketed the card and left the clearing that still echoed with Sakura's moans. She licked her lips at the delightful sound and as much as it irked her to hear it was the product of other men. She still wanted to hear more of it.

"How often does she do this?" She asked.

The man gave her a lecherous grin, "About every weekend. She's usually set up about sundown."

Rin nodded and filed that away for later use.

Rin then retrieved her things and went home determined.

She was going to put in a second jewel.

She wasn't about to have some strangers pleasure her sister more than she could!

She might also make a run to the video store to pick up a 'training' video. If her technique was lacking then all the size in the world wouldn't matter.

There was no way she would half-ass something like this! Her pride as a Tohsaka demanded it!
