Vol. 1 Chapter 5 – The Achievements of the Subjugated Girls

Several weeks had passed since I had subjugated the three girls Reina had asked me to『crush』: Suzuhara Ichika, Mizuki Makoto and Takizawa Mai.

During that time, I told Reina that I had completed the mission she had requested, and received a curt『Good work』as her acknowledgement, along with her forgiveness:『As promised, I’ll let the hidden-camera matter slide.』

With that, I was finally acquitted and released from blame.

However, of course, I did not return to my former life of quietly enjoying ero in the shadows of the sports world like before. That was because I had grown more than a little attached to Ichika, Makoto and Mai, whom I had turned into slaves, and I no longer felt like letting go of my current life.

So I chose the path of continuing as a sports doctor at the dorm. Thankfully, the sports doctor contract I had made with Reina lasted one year. At the very least, I could remain there until the end of the school year.

And so, I obtained the right to live an ideal life: by day, gazing at the healthy, erotic forms of beautiful girls, and by night, having Ichika and the others attend to me while I indulged in erotic that satisfied my carnal desires.

Well, that being the case, I was spending the kind of days any man would envy but it wasn’t as though the dark feelings deep within my heart had completely settled down.

It was about Reina.

Even though I had been threatened, I was grateful for the fact that I had carried out sexual harassment against Ichika and the others, and as a result, was able to subjugate the three of them. Thanks to that, I was now enjoying both a stable life as a sports doctor and a sweet sex life where I never had to worry about women.

However.

Even after taking that into account, the flames of revenge toward Reina grew stronger day by day.

Even so, direct contact like what I had done with Ichika and the others would probably be difficult, since Reina was surely being cautious about that as well.

Then what should I do? I just had to take my time and lay the groundwork.

Yes, first, in order to shatter Reina’s pride, all I had to do was make the three girls I had subjugated win the domestic tournament that would serve as their stepping stone to the world championship.

Reina had dispatched me in order to prevent the success of『top players other than herself.』And I had followed Reina’s instructions and completed my actions.

However, what if the result had been meaningless… no, what if it had the opposite effect? For a perfectionist like her, that should remain in her memory as an unforgivable fact.

In other words, I just had to create a stain called 『failure』in Reina’s life.

In order to carry out that plan, I summoned the three of them and worked out each of their training plans.

Reina’s revenge plan would begin with Makoto, whose track-and-field tournament was the closest.

*　*　*

“Makoto, you’re ready, right?”

“Yes, Master. Please go ahead.”

Makoto herself had told me that she was bad at timing her starts and that she felt anxious about it, so I decided to fix that through training mixed with eros.

A one-on-one lesson on a field I had secretly secured, where no one else would come. Since this was a large training camp meant for developing top athletes, there were quite a few unused facilities, which was a big help. I planned to use this place for Ichika and Mai’s special training too, if necessary.

Of course, there was a reason for keeping the lesson secret.

If Reina found out that I was helping Makoto and the others, it would be over.

“Well then, I want to carefully check your form and how tense your muscles are, so take off all your clothes and get into your starting position.”

“N-Naked…? Understood. Please guide me, Master.”

For a brief moment, Makoto hesitated with an embarrassed expression, but she obeyed my instruction and immediately took a crouching-start position completely naked.

“I-Is this all right? Master…”

I looked over the naked Makoto as if licking her with my eyes. The whiteness of her chest and butt, and the wheat-colored tan of her stomach and thighs. No matter how many times I saw it, the contrast of those tan lines was erotic.

On top of that, her pose looked as though she was practically asking to be pierced from behind and my dick was already reacting.

“Yeah, that’s a beautiful form. Your core has no problems and the tension in your muscles is excellent too. Still, from behind, that fully visible pussy of yours is spreading its labia nicely. It’s quite a view.”

“Au, M-Masterrr. It’s embarrassing, uuh…”

“There’s no need to be embarrassed. Since you’re leaning forward, your huge breasts are hanging down in a rocket shape, giving them a different kind of erotic appeal than usual. It makes me want to grab them without thinking.”

“I-If you did something like that here… auu…”

Breathing raggedly from excitement, Makoto stiffened her body.

Just touching her dangling breasts had made her muscles lock up.

“I see. As I thought, you get tense easily. Your muscles are stiffening from a shake-up as minor as this…”

“Because you make my heart race, Master. And when I’m in the starting position I’m bad at, it makes it even worse…”

“In other words, I just need to loosen the tension you feel in this pose…”

“Eh…? What are you going to…?”

Bacchiiiin!

“Hiiih! Auuuuuh, Masterrr!?”

I came up with a plan and gave her thrust-up ass a vigorous slap.

“Come on, there’s more coming. Keep a clear image of the start in your mind while you feel this stimulation!”

Bachin, bachin! Bashi, bachi, bechin!

“Y-Yes, ahih, hyau, auuuuh!”

As she received the repeated blows, a bewitching tremble began to mix into her pained moans.

“Since you athletes keep pushing yourselves through harsh training, every one of you has a bit of a masochistic side. You’re starting to feel good from being slapped, aren’t you?”

Bashi, bechi, bachin, bachin, pan!

“Because your, hih, way of hitting me, auh, is so good, Master, kuuh, auh, hia, hauuuuuuh!”

“You’re starting to make a nice face. Your pussy is getting wet too. Connect this pleasure to the image of your start.”

“Y-Yes. Au, kuuh, auuuuh…”

“But there’s still some stiffness left in your muscles… Looks like the next stage really is necessary.”

Saying that, I threw off my pants, firmly grabbed the buttocks stained red with handprints in both hands and thrust my aroused dick into Makoto’s pussy, which had begun to grow wet with love juices.

Zububu! Nuzuzuzuzubun!

“Hyauu, fho, ah, au, haaaah, dick～♥”

When I pushed my dick into her pussy from behind, Makoto’s voice sprang up with unexpected pleasure.

“Inside, you’re drenched and sopping with love juices, and you’ve softened up enough. I’ll start loosening you up from here.”

Zubo, nubo, zupu-zupu-zupu, zumu, zubu!

“Hau, fha, aaah, kuo, good, amaziiing, aaah, dick, it feels good. Kuaaah, it feels so good♥ I can’t believe that on the field, in a crouching-start position, auu, I’m receiving your dick…”

The extraordinary act of sex being thrown into Makoto’s ordinary world of track and field excited her even more than usual.

“It’s embarrassing but I’m happy. Hiaaah, hauh, aaaah, it feels gooood♥”

“Ohh, you’re tightening, you’re tightening! You’re giving my dick a nice response. If you can link the image of my dick making you feel good with the moment you start in front of a huge crowd, you’ll be able to relax, right?”

“Hahii, nho, fhaaaah. My weak starts will… feel good? Your dick feels so good, aaah, oooh, fuaaaaah♥”

The more I thoroughly stirred up her female hole, the more the unnecessary tension throughout her body melted away and loosened.

“Next is practice for matching the start timing. I’ll give the signal, so Makoto, you move your hips in time with it. Got it? Here we go.”

After ordering Makoto, I kept pistoning while putting the whistle in my mouth.

“Timing… guh, yeshhh, Masterrr～”

Peeep!

“Nhiiih! Kuo, ah, au, haaaah!”

“You were a little late. One more time.”

Peeep!

“Afuuuh, kua, o-ohhh!”

“This time, you jumped the gun. Stay calm, Makoto.”

“Yes, Master, nho, au, fha, haaaah…”

Since she had added her own hip movements and the stimulation had increased, her breathing grew rougher too, but Makoto’s motivation seemed to be rising. Her vagina walls were rippling as they waited for the signal.

“Your pussy seems worked up, so try tightening your hole along with your hip movements. Here we go.”

“Haaaah… hiiiih… nho, afha, I’ll tighteeeen.”

Peeep!

“Nwoh, ah, aaah, oooh, nfuuuh!”

“Ohh, good. That one was perfect. My dick felt that tight squeeze too.”

“Fhaaah, that timing… on your dick… auu, haaah, the start…”

Makoto seemed to feel the response too. With a melted expression of joy, she kept twitching in small spasms.

“Make your body completely remember that feeling. We’re going to keep going, one after another!”

“Yeeesh, give me lots, Masterrr～♥ Haa, aaah, nfuu～♥”

Pip! Peeep! Pii! Peeep!

“Nhiiih! Kuhooo! Hauh! Aoh, fuhaaaah, aaaaaah! Fhaa, how was it, Masterrr, my start, nho, with your dick, nnooh～, crouching～ggg, staaart～♥”

“Yeah, at first you still had some tension left and kept mistiming it, but you’re fine now. You’re tightening your pussy and snapping your hips back perfectly with the signal. If you do it with this image during the main race, you’ll be able to make the best start!”

“Haaaah, I’m so happyyy. I overcame something I was bad at. Masterrr♥ Nhaaah, your dick… hia, good♥ Fha, ah, aaah, good. I’m coming♥ I’m so happy, hey, Master, auuuuh～♥ Praise me… please… nunaaaah♥”

“Yeah, you did well, Makoto. This is your reward for working hard, and an early celebration of your victory. I’m going to cum. I’ll cum inside you. It’s coming, here it comes!”

“Hawaaaah, even though you’re the one who instructed me, I get a reward too? Aaah, I’m so happy, Master. Give it to me, all of it inside. Your dick, hauuh, kuhaaaaah♥”

Dobyuuu! Byururururu! Pujaaa!

“Hawaaaah, it’s coming, it’s coming, it’s cuuminggg! So much hot reward semen♥ Hoaaaaah, I’m coming, I’m coming, I’m coming, I’m coming♥ The start feels so gooood♥ Hoaaaaah, afaaaah, hauuuun♥”

“Ohh, that’s a good climax. Your squirting has plenty of force too and your vagina is squeezing hard around my dick, giving back such a good feeling! Don’t forget this momentum when you start!”

At the moment she received my ejeculation, Makoto reached climax with an intense squirting that seemed to foreshadow victory.

“Haa, nho, fha, aaaah… With this kind of method, my weak starts…now they’re connected to a pleasurable image, nha,and I’m starting to look forward to the start. Oooh, aaah, haaaah… That feeling of your cum coming into me… haaaah♥”

While losing herself in the lingering afterglow of pleasure, Makoto replayed the moment she came over and over again, strengthening its connection to the image of starting.

“Looks like there’s nothing to worry about anymore. Overcoming your weak point with just one lesson, that’s Makoto for you.”

Pujyujyu, bubibibi, bushuuu!

After finishing my role and pulling away, white, cloudy remnants spurted from her pussy opening where my dick had slipped out.

“Ngh, ouh, haa, ah… aaaah♥ Thank you very much, ah, haaaah… Master♥ Thank you for helping me overcome my weak point through guidance that made me feel this good with your dick… I’m all right now. I don’t feel nervous or anxious anymore. The sensation of your dick entering me at the start has been engraved into me, haa, n, fhaaaah…♥”

Freed from pleasure, Makoto placed both hands and knees on the track, breathing from her shoulders, yet spoke her determination with an entranced gaze.

“At the tournament, I feel like I’ll be able to draw out strength beyond my actual ability. I’ll definitely win my way through and dedicate the championship to you, Master, so please look forward to it♥”

“I know your ability well, Makoto. I’m not worried about anything. Go out there and run to your heart’s content!”

“Yes, Master♥”

She answered in a bright, refreshed voice, as though her worries had been swept away.

And then, a few days later, Makoto entered the tournament in perfect condition, set a new record and achieved a magnificent victory.

*　*　*

With an overwhelming record, Makoto won the tournament, and for now, we had managed to carve out the first step toward revenge.

The next athlete was Mai.

However, when it came to Mai, I was a little troubled.

The reason was that volleyball is a team sport. Even if Mai alone stood out, if the other members dragged her down, winning the championship would be impossible.

In that case, before the final match of the volleyball tournament, I came up with a small demonstration to strengthen the team’s unity and draw out even more effort from them.

The location was, of course, the volleyball court inside the gymnasium. The club members, who had been called there by Mai, had been told that something special would take place and they gathered with excited, expectant expressions.

“Yes, everyone, gather around.”

“Huh, C-Captain!?”

The moment Mai appeared wearing a skintight uniform that emphasized the lines of her body, all the club members erupted into an uproar.

Wearing a collar, with her nipples and clitoris, fitted with piercings, exposed through holes opened in the fabric, she was met with gazes that seemed to question her sanity.

As the club members swallowed their breath and lost their words, one girl, perhaps the vice-captain, finally opened her mouth.

“W-What happened to you, dressed like that? Please take off those weird accessories and wear a normal uniform!”

“Even though the finals are coming up, you’re slacking off! Don’t waste time with idle chatter.”

However, with that sharp rebuke from Mai, whose attitude alone remained as firm and dignified as usual, the girl from earlier was overwhelmed and once again shut her mouth.

The club members murmured in confusion at the sight. However, as if none of that mattered to her, Mai began delivering her instructions in front of them.

“Thanks to everyone’s hard work, if we win the next match, we will finally be able to seize the championship we have long desired. To make certain we snatch that victory, I have decided to introduce everyone to the wonderful sports doctor who drew out my abilities to their absolute limit.”

Prompted by Mai, I gave my greeting.

“I’m the sports doctor who was just introduced. Everyone, nice to meet you.”

However, their reaction was not very favorable.

“Isn’t that the male sports doctor who came here the other day…?”

“Everyone was saying he kept staring at the athletes’ bodies with perverted eyes, and it felt gross…”

“Why would the club president bring such a creepy doctor here…?”

It seemed that bad rumors about me had spread, and together with their hushed whispers, doubtful gazes were directed at me. Well, most of it was true, so I couldn’t exactly deny it.

However, in the face of those rumors, Mai raised her voice once again.

“It seems some ridiculous rumors have been going around but Sensei’s intense gaze is a serious one, meant to ensure that he does not miss even the slightest sign of an athlete’s poor condition! I misunderstood him at first too but thanks to Sensei’s precise treatment, I am now in better condition than ever before and able to display even more than my full ability! You all know that as well, don’t you?”

“It’s true that the club president has been amazing lately, but…”

Since the results had clearly appeared, the skeptical murmuring began to shift into interest.

“I had never thought about anything but volleyball and I mistakenly believed that if I just piled on harsh training, I would become stronger, only to hit a wall. But my foolish self was awakened as a female by Master, with his huge, virile dick…”

The club members were bewildered, their eyes darting in shock at the sudden confession.

“Huh? What did the club president just say…? F-Female!?”

“What does she mean by Master? Why would she call an ordinary sports doctor that?”

As Mai began speaking passionately with a melted gaze, the voices of the club members, which had almost turned favorable, reverted back into confusion.

“To guide a little girl who did not even know the pleasure of being female into a higher world, using his magnificent dick, that was the finest instruction. To revere as Master, fawn over, and serve a sports doctor who gives such wonderful treatment that no one else could ever accomplish, just how happy that is for a female! I shall actually show all of you as well, and let this serve as encouragement for the final match!”

When her speech, which was hard to tell whether it was encouragement or lovestruck boasting, came to an end, Mai turned toward me and opened her mouth.

“Then I humbly ask for your guidance, Master.”

Naturally, I answered those expectations.

“All right then, I’ll allow you to serve my dick with your big breasts and lewd mouth. Make sure you entertain me properly, got it?”

Amid the volleyball club members’ uproar, I presented my dick to Mai and gave her permission to serve me. Then Mai, with unsteady steps like a moth drawn to a lamp, brought her face close to my lower body, placed my shaft between her full, ripened breasts, and began breast-service oral.

“Nmmffohh. Haa, thank you very much, Master. Mmohh, nchu, becho, chuba, muchu. Nn, delicious. Ohh, dick… so tasty. Nhaa, aah, Master, how is it? My sucking and my breast-stroking…”

“Ahh, both the breast-job and the oral are excellent. Since the club members are watching, you’re putting your heart into it right from the start, aren’t you?”

The club members began to stir as they watched the scene.

“No way… That strict club president is doing something like that to that thing…!? He must have gotten some kind of leverage over her or brainwashed her, right?”

“Get away from the club president, you pervert! Do you really think this kind of sexual harassment is allowed!?”

Voices flew back and forth, filled with shock at an act that would have been unthinkable for Mai’s personality up until now, and anger toward me for making her do it.

“Nfuu, because I want everyone to know how wonderful it is to serve Master’s amazing dick♥ Please don’t misunderstand Master either, and watch, npuah, feel the joy of entertaining his dick! This is a club president’s order! Nwo dick, wohoh♥”

Calming the indignant club members, Mai heated up her full-fledged demonstration of breast-service oral.

“Nbuah, hamun, nchu, kuchu, pero, pecho-pecho, chupa♥”

At the sucking sound of Mai’s saliva intertwining, several of the club members gulped.

Even as they denied it with their words, it seemed they could not tear their eyes away from the indecent display unfolding before them.

“Ahh, she’s licking all over a man’s c***… h-his thing… Something that filthy. Club president, please come back to your senses!”

“She’s shaking her breasts like that herself too, stroking that thing. Club president, ahh, no…”

　With practiced movements, she moved the bulges sandwiching the c*** up and down, and as she greedily sucked on the g****, everyone was shocked, yet unable to look away.

“Nn, the c*** is already throbbing like it feels good, with p**-c** dripping thickly from the tip♥ But you must not judge by that reaction alone. Nchu, chupa, muchu. You have to read how Master is feeling from other factors too… haa, nnnh♥ Look, nchu, reroro, they say the underside is the most sensitive part of the c***. Chirororo, pero, reron.”

“Kuoooh, that’s good. The way you’re teasing and digging with the tip of your tongue. It works best on the underside.”

“I am honored that it pleases you. But I thought that right now, Master was in the mood for the tip more than there♥ Zujyujyujyujyujyujyuh! Zobobobo, bubobobo, juba, chubaba, zutchuuuuuh!”

　Without simply swallowing my praise whole, she immediately tightened her pursed lips around the g****, attacking the s*** at the tip with an utterly vulgar-sounding vacuum.

“Nwooooh, that feels insanely good. You figured it out, Mai. As expected of you, kuaaaah!”

　Unable to bear the breath-stealing pleasure, I arched backward.

“Njuuuh, and with the breast-stroking too, it’s not just about stroking hard. Gyu, nnnh, the c*** wants to be squeezed. Nffu, affuu.”

“Ohh, exactly. Both the paizuri and the oral, this is exactly what I want right now.”

The throbbing of the spongy tissue gained force and the amount of fluid doubled with each pulse.

“Nbu, fubaa. In this way, Master taught me through his dick the technique of reading the other person’s psychology and instantly returning the optimal movement♥ And now, nchu-chu, rero-rero, beron, peron. The whole tip wants to be licked all over.”

As Mai’s indecent display accelerated, the voices of protest from the club members began to dwindle.

“The paizuri too, nnnh, nffu, haffuu, with fast strokes, shiko-shiko on the stiff shaft. Nffu, affu, nuchuru, reron, beroro, peroo.”

“You’ve grown even more clever. Before, you wouldn’t have been able to read me this far. With this, you’ll be able to toy with your opponents through strategy. You’ve grown, Mai.”

“Haa, aaahn, it’s all thanks to you, Master. As a sign of my gratitude, I’ll dedicate the tournament victory to you♥ Nnnh, nuchu-kuchu, reroro, affu, haffuu, hawaaaah♥”

Showing the effects of the treatment, she brought me precise pleasure while growing wildly excited.

“…Th-There’s no way something like that has anything to do with volleyball. What do you mean, strategy…? She’s just doing something filthy…”

“But…it’s true that lately, the club president seemed like she was reading her opponents’ movements ahead of time. And she seemed to understand what that man wanted…”

“A-A man’s thing reacts like that? The club president is doing something lewd but she looks like she feels so good…”

The club members, who had shown disgust until a short while ago, were now absorbed in watching Mai’s actions before they knew it.

Perhaps their female instincts had been stimulated, as more of them began letting out troubled sighs while restlessly twisting their hips.

“Yes, it feels so good. When its pleased, I also get more and more♥ I want everyone to feel this happiness too. I want you to awaken your instincts as females and seize victory together with me♥”

Mai pleaded with the club members watching over her with melted, female expressions.

There was no longer any trace of the gallant captain she had once been.

“Nfuu, abaaaah, dick, nchuu, jururu, chuba, npaa. Nooo, hau, this is alreadyyy♥”

Meanwhile, the inner pressure of my desire had also risen from the breast-service oral that immediately gave me the pleasure I wanted.

“You’ve shown the club members a good example. You’re the model of a female who fawns over dick, Mai! As encouragement before the final, I’ll give you a female’s favorite treat! Build an erotic, strong body with semen protein and seize victory! I’m going to release it, I’ll give it to you, it’s coming, coming, I’m ejaculating, semen is coming!”

“I ammm, nzujururuu, only proving Master’s guidance exactly as it is. Nchubaa, mujujurujuruuu♥ Nfoh, the semen, it’s coming, I’ll receive this reassuring gift, nhaa, haaah♥ With semen fluid full of protein, oooh, afu, I can definitely win. Nbuu, abaaaah♥”

“I’m cuummmgggggg!”

Bubbyuu, byuru-byuru, doku-doku-doku!

“Nnboaaaah, wobo, nbubuu, semen,semennnn, nba, gbuaah♥ It’s so thick, it’s coming out, ebu, nnbaaa, so muuuch, aba, nbua, the tasty stuff from your dick, hau, abu, thank yooou, goboh, very muuuch, buuuh♥”

So as not to spill even a single drop of the semen that had been released into her mouth, she puffed out her cheeks like a squirrel and trembled with gratitude.

“Ohh, woboh, abuaaah, nba, habuah, ngggbuuuuuh♥”

“Ohh, you really stored it up. Both your oral and your breast-job gave such thoughtful stimulation that I ended up releasing a whole load of semen. Savor it as much as you like.”

“Gbuu, fumuu, powoh, obua, hobaa. Nn♥ Nnnh♥ Mmm, delicious♥”

With a melted gaze, intoxicated by the wave-like sweetness, Mai slowly savored the mouthful of semen.

Meanwhile, after seeing that the act had come to a pause, the club members began voicing their thoughts as they pleased.

“Right now, is the club president’s mouth filled with stuff that came out of that dick? Her cheeks are puffed out so much, and she looks like it tastes good… Wh-What does it taste like…?”

“What’s swelling from the club president’s nose, is that a nose bubble made from the stuff released into her mouth? For her to look that happy, is doing lewd things really that good?”

The club members could no longer hide their curiosity. As Mai looked ecstatic with a semen nose bubble swelling from her nose, they breathed heavily, as if wanting to switch places with her.

“Nbu♥ I’ll recei…ve it♥ Nngh, gubi, gubi-gubi, gulp, gulp, gulp, pufaa, deliciousss♥ Zujurujuru, jururururuuu, dick♥ Chuba, njupaa, ngu, gubu-gubu, hafu♥ There’s still more coming, juzuzuzu, semen, zoboboboboo, jupo, chubo, jururu, njuuuuh.”

Mai thoroughly savored the love juice protein that had gathered in her mouth with her tongue, then swallowed the semen as if she intended to suck every last drop out of the penis. From that fierce sucking, her once-round cheeks hollowed, and her lips puckered like a hyottoko mask.

[comical traditional Japanese mask]

“Haa…… aah…… I drank it all. The juice that came out of your dick…… it tastes delicious.”

“For that Club President to end up like that, is it really that amazing? That sports doctor……Master’s dick……”

“We’re volleyball club members too, the Club President’s teammates, so…… aah……”

The members, who had shown nothing but disgust until now, saw how completely absorbed Mai was and began directing expectant gazes at me.

And Mai, noticing that, spoke the words I wanted to hear on my behalf.

“That’s right. Now you understand, don’t you? How wonderful Master is. Haa, nn, afua, aah……♥ Our opponents in the finals are strong……But if the whole team receives Master’s treatment, and if he gives us female guidance with his wonderful dick……”

The club members gulped and waited for her next words.

“Our individual abilities will improve, and we’ll be tied together by the wonderful bond of being rod sisters. With tight teamwork bound through the vaginas that have been filled by a huge penis, we’ll be invincible. Let’s definitely win the tournament and dedicate it to Master!”

As the saying goes, seeing is believing. And after the club members were forced to witness, right before their eyes, Mai, who had once been so pure, dignified, kind, and strict, falling into female submission, they had no choice but to believe……no, they were made to believe it against their will.

“That dick must definitely feel amazing.”

Before long, the circle that had formed around Mai and me began to collapse and the members came flooding toward us.

“Ahh, please, Doctor…… no, Master. Please make me female with your dick too, just like the Club President!”

“Master, your wonderful semen, please pour it into me too! Please awaken me as a female!”

One after another, the club members eagerly begged for the pussy, each trying to be first.

Of course, my answer had been decided from the very beginning.

“Yeah, I’ll make the entire team female. I’ll make you all reach climaxes and draw out even more of your true ability!”

The club members crowded around me, their uniforms stained at the crotch with love juice.

I took each and every one of them in turn, made them climax over and over, and awakened them to an even higher level of ability, both as athletes and as females.

And then, although the tournament final had been expected to be a difficult battle, once it actually began, Mai and the others dominated from start to finish. As a result, with their overwhelming teamwork, they splendidly claimed the championship.

*　*　*

Makoto and then Mai, had both produced results.

Only Ichika remained.

On the day before the swimming tournament, I made my way to the indoor pool to check on her condition.

Then, by the poolside, a girl troubled all by herself caught my eye. Of course, it was Ichika.

“Uu, I have to do my best. I have to win and live up to Master’s expectations……”

“What’s wrong, Ichika? Are you nervous?”

“Ah, Master!? N-No, I’m fine. Tomorrow, I’ll definitely…… win…… so……”

Even though she was clearly stiff from the pressure, when I called out to her, she hurriedly forced a smile.

“Well, don’t push yourself too hard. In that state, your posture will worsen too and you might hurt your body when you dive. I’ll check your form, so try doing it.”

“Master will!? Thank you very much. Right away.”

Perhaps my suggestion had made her that happy, because her gloomy expression from earlier vanished completely, and Ichika headed toward the starting block with a smile blooming on her face like a flower.

“Ah, right. I forgot to mention it but today, I’ll have you wear my specially made swimsuit.”

“Specially made!? Y-You care about me that much…… Master, I’ll change right away, please watch me!”

Though her cheeks reddened shyly, Ichika changed into the swimsuit I handed her.

The fact that she had reached the point where she would change in front of me without my saying anything was also a major plus.

Before long, she had changed into my specially made swimsuit, one with no fabric covering the lower body or both breast areas. Wearing a pure smile like a girl who had received new clothes as a birthday present, she stood before me.

“H-How is it? Does anything look strange?”

“No, just as I expected, it’s perfectly erotic. All right, try standing there.”

“Yes!”

Ichika answered energetically, stood on the starting block, bent her body, and took her diving stance.

I watched her from behind, but it was even more erotic than I had imagined, and my crotch throbbed despite myself.

The start. That is the moment when the tension rises highest during a competition. When that was recreated in an erotic swimsuit…… the gap was incredible.

Her forward-leaning posture, with her rear pushed up, left both her genitals and anus completely exposed.

At the same time, her breasts spilling out from the torn swimsuit were also quite enticing.

The eroticism blew away all sense of tension and my penis was throbbing like crazy.

“I see. Your form itself isn’t bad. The muscles from your legs to your rear are nicely tightened, giving you a good sense of dynamic motion.”

What I really wanted to bluntly say was that her power-packed, plump thighs and tight ass were irresistible but I translated that into an observation that sounded like a sports doctor.

“I-Is that so? Then, I’ll be okay, right?”

“Hmm, but I suppose the tension really is affecting you after all. Your anus is too tightly clenched.”

“M-My anus…… my buttocks……?”

Just as she was beginning to feel relieved, having such an embarrassing place pointed out made Ichika’s face flush even deeper.

“Yeah, see? Being told that made you even more nervous, didn’t it? The chrysanthemum wrinkles tightened up even more.”

“Uu, n-no, that’s……”

The more I pointed it out, the more Ichika unconsciously fidgeted with her rear and made her anus tighten.

“So having you change into the special swimsuit really was the right call. If you had stayed in a normal swimsuit, I wouldn’t have noticed.”

“As expected of you, Master. So, what should I do? At this rate, I’ll miss my chance to win the tournament……”

“Don’t worry. That’s what a sports doctor is for. I’ll carefully loosen up Ichika’s tense anus with my massage.”

As I said that and ran my finger along her tightly clenched chrysanthemum gate, Ichika cried out in surprise.

“Eh!? Hawa! Master!? Y-Your finger, in a place like that…… No, please don’t, it’ll get dirtyyy～”

“No, I told you before, but this part of you isn’t dirty at all, Ichika. If anything, isn’t it a pretty little bud? And even if it does get dirty, I can’t let my precious female athlete get injured because of tension. Still, it really is tight……”

“Hau, Masterrr♥ Au, nfuu, ha, aah, fuaaa～”

Ichika’s enraptured face, moved by my words, trembled ticklishly as I scraped at the wrinkled folds with my finger.

“Hiu…… ao, haaah, somehow, it feels kind of itchy, nn, strange. It’s the first time someone has touched me there, so, a-auuu. It’s embarrassing, but, fuaaa……”

“You said it’s the first time someone else has touched it. Have you been playing with it yourself all the time?”

Since it looked like digging in would be difficult, I pressed with my finger as if applying pressure and massaging it in.

“No, I haven’t! I haven’t done anything like that myself either. Only when I wipe my bottom and such…… Please pretend you didn’t hear what I just said. Hiu, nn, kufu, a-aah……”

“What’s wrong with playing with it yourself? If that helps you relax and loosens the stiffness, I think it’s actually quite a good method.”

It might be interesting to teach her the pleasure of rear masturbation and make it a habit for her like this. Wait, oh, her anus is gradually……

“I-Is that…… so? Aah, au, nfua, somehow, this…… haa…… aaahn, it feels strange, haaah, my bottom is…… aaah～”

Maybe because I had made her conscious of it, her anus  rapidly loosened and my fingertip sank in easily.

“Hyau, a-au! Your finger, Master’s finger, hauuu, it’s gone in, inside my bottom!? Fuaaa, it’s dirty! Master, you’ll get dirtyyy!”

“I told you, Ichika, your anus is clean, so it’s fine. My finger finally got in, so I’m going to loosen you up even more.”

I firmly stirred Ichika’s anus with my finger as she grew flustered from the foreign sensation and embarrassment.

“Hauu, nnooh, aaaah, nooo. Aah, nooo. It feels strange! Fuaaa, my bottom, Masterrr. It’s embarrassing, nhi, ohiii, auaauu, funuuu～!”

The more forcefully I stirred, the more intensely Ichika showed her embarrassment, but her rear unconsciously pushed upward, trying to take even more of my finger in.

“All right, if I’ve done this much, we can move on to the next step. I’m going to put my dick in to really loosen you up, so you show me how well you can welcome it with your anus.”

Even the anus that had been so tight now remained open, slick with intestinal fluid, after I carefully loosened it with my finger.

“Hia, you’re going to put your dick in? In my bottom? No, aah, but since it’s yours, Master, I have to welcome it. Hauuu.”

The rod that felt good when inserted into a vagina was now going to be inserted into an excretory hole. Though confused by that bewilderment, Ichika was driven onward by her loyalty as a female slave.

“I believe in you. I’m counting on you, Ichika. I’m putting my dick in!”

Zububububu, nubububu, zunununubuzuzun!

“Fuggiii, nfuuufuuu, kuoo, my dick is burying itself inside meee. Nwoo, ohoooo～!”

“As expected, even loosened up, your anus is tight. But that actually makes it irresistible. Here, I’m going all the way to the base!”

“Nnguu, woooh, nnooh, hagguhhh! Awa, nfuumuuu, oah, dick, it went into my bottommm!”

Forcing open the powerful tightness that tried to resist the insertion, I buried my dick all the way to the base.

“Ooh, you’re already welcoming me with such a pleasurable squeeze! But just squeezing isn’t enough. Your anus is also a sex organ that can take a penis, so I have to develop it into a female hole that flatters me completely, just like your pussy.”

“Fuguu, I see…… Aaaah, your dick is fully inside, in my bottommm…… gufua……♥”

“What’s wrong? You still seem nervous.”

“I’ll do my best, Masterrr. So that your dick can feel pleased. Nn, kufu, oooh, nnnh.”

The serious, hardworking swimming girl, even though the shock of her first anal insertion had not yet settled, was straining herself to move the folds of her butt.

“That’s the spirit. I’m going to piston you like I would with a vagina, so control your anus properly and try flattering my dick. Once you can do that, you’ll be able to control your tension by your own will. You’ll be able to face the tournament in your best mental state too.”

“Aaaah, this is for my sake toooo♥ Please give me your pistons. I’ll devote myself to your dick. Please give my anus something intenseee～♥”

As Ichika trembled with pleasure and focused her awareness on her anus, I began thrusting into her with all my strength.

Zubo, nubo nubo nubo, zun zun, zumun!

“Kuoooh, nnooooh, howoh, ohoaaah! Hauu, amazing, so intense, haaaah, in my bottommm! Dick, your dick*, like thisss, nguhaaaah, kuhhoaaaah!”

Though she herself had asked for intense strokes, once the merciless dick was slammed into her first-time anus, all she could do was grow flustered from the overwhelming stimulation.

“Come on, don’t panic. Calm down and grasp the sensation of my dick. You should be able to do it, Ichika.”

Without spoiling her here, I continued the anal pounding that felt good on my dick, giving her only advice.

“Nhii, y-yes, Masterrrr. The control of my anus, right? Nn, nngh, fuhhii, hoo, hiiii～♥”

Ichika steadied her breathing the same way she did when breathing during swimming, then focused on making her anus move.

“Ooh, the folds of your anus have started rippling. You were only squeezing before but now you’re shaking my dick. That’s the way.”

Though still awkward, she was returning stimulation in service.

“Hahii, nnohooo, because pleasing your dick is what makes it a female hole. Kuhoo, owoooh! My bottom too, like a vagina, will serve your dick, Masterrr, as a holeee～♥”

Gudju, bujuru, zucchu, nucchu, bucho, jucho, jubo jubo, nyuppo!

“Your pussy juice is dripping plenty too, and you’re getting better and better by the second. Ichika, you’re starting to control the movement of your anus folds. You’re taking care of the parts that feel good for my dick.”

“Naaah, that’s because Master’s guidance feels so good. Your dick is enjoying it! It’s twitching and twitching, haa, aaah, I’m so happyyy～♥”

As I kept pistoning at a good pace, Ichika’s anus seemed to grasp the trick and made remarkable progress.

In response to my movements, she skillfully changed the wriggling of her intestinal folds, squeezing and rippling as she welcomed my dick with stimulation that never grew boring.

“Your anus and your tension have both loosened up enough. With this, you should be able to control yourself properly even during the tournament, right?”

“Yeshhh, I cannn. I won’t get nervous, I’ll give it my all, haaaah～. I’ll win, for Mashterrr～♥ My bottommm, ooaaaah, my bottom is like this now, so. Haaah, dick♥ Yourdiiickk～♥”

As if offering proof of her victory, she used the freely wriggling flesh of her aus to offer pleasure to my dick.

“To think you learned this much self-control in such a short time. Here’s a reward for hardworking Ichika! Remember this stimulation during the competition and use it as encouragement!”

I gave powerful pistons to her, which had grown into a female hole, as if making it memorize the shape of my dick.

Zubo zubo zubon! Zupan zupan pan pan! Zubun, zun zun, zubbon!

“And this one too. Take this juice with your anus like you’re planning to get pregnant through it. Cum with your anus! I’m going to release, I’m ejaculating, here it comes!!”

“Ahiiih, this is amazing, nhooo, it feels so gooood, amazinggg. My bottommm, owoooo, so good♥ Thissss～♥ Nnooo, oaaaah, Mashterrr, hoa, nnoooaah, hauuuuu～♥”

“Nnoooh, even with my anus, I’m cumming. I’m getting pregnant. I can’t control ittt, so aaah～♥ Haaah, dick, oooh, nwohoooh, it’s coming, howah, uwaaah～, already, alreaaady, nhooooh-waooooh～♥”

Dobyuuuu! Birubyurububyubyu～! Pushaaa, puju-puju-puju!

“Hahiiih, kuoooh, nhaaah, it’s coming, spurting in my ass～♥ Howaaah, I’m alsooo, going to release, releasinggg, hehaaah, nngh, hafuuuu～～～～, ah, auh, hawaaah～♥”

Despite this being her first anal, Ichika had ended up reaching an anal climax. Even while being swallowed by waves of pleasure, she seemed to be desperately trying to control her emotions, but…

“This, this is, nheah, control, is impossibleee～♥ My ass, hoaaah, like this, hawaaah, nnah, howah, hauuuu～～～～n♥”

“You really cummed hard with your ass too. It’s already a splendid female hole. Even while I’m ejaculating, you’re serving me properly, and it feels good.”

Having been finished into a female hole that would not lose to a ppussy and satisfied with the condition of Ichika’s anus, which was just like her, never slacking in her service until the very end, I poured every last drop of semen into her.

“Ahhh-aaahhh～～, haaah-aaahhh～～, I never knew my butt could feel this good, nnah, I didn’t knowww♥ Thank you for teaching me with your dick, nfah, thank you very much, Masterrr, wohi, ahi, hehaaah～♥”

Even while melting into an ahego-like daze from the lingering afterglow of her climax, she politely expressed her gratitude.

“The fact that you can control both your butthole and your nerves like this is because of the strength of heart Ichika had from the beginning. All I did was draw it out from your anus with my dick.”

“Nooo, everything……is thanks to you, Masterrr. Nnah, haah, afuuuhhh～”

“Looks like you still can’t fully have confidence in yourself. Then this will be your final training. Even after I pull my dick out don’t spill a single drop of semen from inside your butt.”

I gave the order to the humble Ichika, pulled my dick out of her anus and moved away from her.

“Wahih! Nwooo, kuuu, howa, nkuaahh! Master went through the trouble of spurting it inside mee, aaah, this thick juiceee～ I won’t spill it. I’ll do my besttt. Nnmmuu, wuuuhhh, nnhi, kuffuu, munuuuhhh～”

Though it happened suddenly, Ichika tightened her anus as if she had nailed the start at the perfect timing, damming up the semen that had pooled inside her.

“Oh, you didn’t spill any. Excellent, Ichika. Endure it just like that.”

“Nwohyyu, kuffuu, because it’s a gift from Masterrrr. I won’t spill it. I’ll keep it inside my butt foreverrr, nnn, I will.”

With the limp exhaustion that came after climax still weighing on her, her hips jerked and trembled, yet she gritted her teeth and continued holding the semen in.

“If you can endure this much, then I don’t have to worry. Ichika really is a girl with a strong heart. Keep that same spirit for the tournament too, and do your best without getting nervous!”

After giving her my final encouragement, I slapped her trembling butt.

Bacchiiin! Pan-pan, bashin!

“Higiiiiih! Howawaaah～, nooo, it’s coming out. Kuoh, faaah, sperm, aaah, nnmuu, it’s, ah, it’s coming ooout!”

Bibyubyu, beryuryu, dobyobobobooo～～～! Bujaaa, bushu-bushu-bujuuuu!

“Hawaaaah……, kuheaaah, hohaaah～, it came, it came ooout…… hawaaa, nnaaaah, Master’s semen, his gifttt…… haah, nnaaaah, faaah, but…… ah…… aaah…… nniiih, it feels…… good. Haah, ahaa……♥”

She tried her best to hold it back, but from her anus, loosened by pain and shock, a plentiful amount of cloudy white fluid was forcefully splattered out.

“Ohh, that’s almost more forceful than my own ejaculation. Looks like training your butthole was worth it.”

“Hau…… uuh…… no…… that was so indecent, it’s embarrassing…… and all of Master’s semen spilled out too……”

When I praised her half-teasingly, she blushed with shame while regretting the lost semen.

“But it felt good right until the end, didn’t it? During the tournament too, as long as you remember this, you’ll be able to give it your all without getting nervous, right?”

“Yes, of course. Thanks to you, Master, I’ll be fine now! I’ll definitely dedicate my victory to you♥”

Ichika, who had been stiff with tension and anxiety, now returned a smile full of confidence.

At the tournament the next day, Ichika swam freely and comfortably with a pleasant-looking smile on her face, winning with an overwhelming time.
