“Shiga, do you think something’s… off?” Mushanokouji Saneatsu felt… weird. He couldn’t quite place why, but just felt a little strange. Like he woke up on the wrong side of the bed or something. Across from him sat his best friend, Shiga Naoya. He was glad he could catch him, since the other man seemed to be always busy helping people out. He leaned against the back of the couch, one leg bent over the other, looking nonchalant and cool as always.

“Hm?” He tilted his head at him, raising an eyebrow. “Off in what way?”

“I just feel… weird.” Musha tried to explain, putting a hand to his lower back. “And my back hurts a little. Do you feel weird, Shiga?” This only got a shake of the head.

“Nope.” Was his proper answer. “Maybe you slept wrong or something?” Yeah, that was a good suggestion. “Or maybe you’ve been doing too much garden work. Your body’s frail, you know.”

“Not that frail, come on now.” He laughed, Shiga joining in with a chuckle. “Also, I’ve been sleeping really well! Full 8 hours every time.”

“Anyways,” Shiga started, “you got a pen? I gotta jot some stuff down for later.” While normally Musha had one on him, this time he did not.

“Oh… you want me to get you one?”

“If you could.”

Musha had no idea. Not a single goddamn clue.

He put his hands on his knees, getting up from his chair, where Shiga could see what was most likely the source of his weird feeling. He was sitting on a custom horse dildo so wide and so long that it would completely destroy the guts of any normal person. Good thing they were not normal people.
Shiga watched hungrily as his friend’s asshole fitted snug around the bumps and veins of the toy as he slowly rose, before he patted his chest down, finding a pen inside.

“Whoops!” He exclaimed, holding it up. “Had one on me the whole time!” Musha playfully rolled his eyes before he sat back down. Shiga enjoying toying with his friend like this, making him fuck himself on that huge toy without any idea that he was doing such a thing. He had to lock his dick away in an extra-large cage beforehand just so he wouldn’t get an erection, though he often felt pressure as he wanted to get hard anyways.

When it was time for the two of them to leave, Musha got off entirely, the dildo head popping out of his hole with a wet pop, getting juices everywhere. His pants were ripped from behind, so Shiga could see his wet, puffy asshole, so swollen around the rim that it almost looked like a donut.

It took hard work to get it to this point, though.

“Alright, Shisho, what are we doing here?” This was months ago. Shiga had properly settled down from his trip where he got properly indoctrinated and brainwashed, and now served his Mistress, their Librarian. It was just after dinner, when she called him to meet her outside Musha’s door. She had her regular soft and kind look on her face, though Shiga knew her. They were going to do something incredibly erotic.

“Nao-chan…” She reached up, cupping the side of his face. “You love me, right?”

“Of course I do, I’m your slave.” He answered like it was the obvious answer.

“And you want me to have more slaves, right?” Shiga laughed a little, putting his hand on top of hers.

“Mistress, I keep asking you to let me creampie someone to brainwash them. You gave me brainwashing cum, and then you won’t let me use it.” The Librarian gave him sweet puppy eyes, and Shiga felt any annoyance he had fading.

“Don’t you trust my plans…?” He sighed, closing his eyes as he gently nuzzled her hand.

“I trust your plans, Mistress… I do. I just hope you let me have my way one day.” He removed her hand before he looked over at the door.
“So are we here to brainwash Musha? Can I creampie him-”

“I said no.” She cut him off. “We’re going to have your friend enslaved eventually, but I wish to have some fun with it. Play the long game, as it were.” She unclipped a set of keys, picking one out and using it to unlock Musha’s door. Of course she had keys for every door, she was the Librarian.

Inside was Musha, who was fast asleep in bed. He was on his side, hugging a pillow, but in the way that his ass faced more upwards. Shiga quietly hummed, noticing how early it was.

“I get that Musha wakes up early to try farming…” he whispered as quietly as he could, “But it’s really early to go to bed.”

“You don’t have to whisper.” The Librarian spoke at a normal volume, closing the door before she approached the sleeping author. “I have his dinner drugged with sleeping pills every night. He’s not going to wake up before they wear off, and I know exactly when they wear off.” Shiga whistled, quite impressed. He shouldn’t have doubted her plans, the young lady had her ways when it came to sexually enslaving guys. She pulled Musha’s covers up from the side, exposing his ass which was covered by pajamas, before she pulled them and his underwear down.

Musha’s asshole… wasn’t entirely tight like Shiga was expecting it to be. There was a little discoloration, a little puffiness around the rim… clear signs that someone or something had penetrated it before. He glanced over at the Librarian, immediately suspecting that she had something to do with this. And he was soon proven right as she reached into her bag, pulling out a small device. It looked like a glass jar with a small dildo attached to the inside, extending 15cm past the rim. Attached to the outside were two hoses with bulbs and air release valves at the end.

“What the hell is that…” He muttered, but figured it was going to be explained. The Librarian seemed so happy to have the toy in her hand, especially as she brought it to Musha’s behind. After lubing the dildo up, she slipped it inside him, pushing down until the rim of the jar was snug against his skin. She kept it in place with one hand, while she started squeezing one of the bulbs with the other. Shiga watched as the skin within the jar started swelling up, pressing against the sides and being pulled upward by the vacuum. She could now let go and start squeezing the other bulb.

“The dildo’s inflatable and keeps his innards from coming out as well as loosens him up.” She finally explained, making Shiga nod in understanding.

“And we just leave him like that?” He asked.

“Well, I come in in the morning just before he wakes up and I take it off…” She explained, shyly looking to the side. “But I don’t want to interrupt your sleep so you can see it… his anus is so puffy and cute, but sadly it goes away after a little bit. That’s why I do this every night!” She put a gentle hand on Musha’s hips, gently rubbing it. “If I keep at it long enough, he’s going to have a truly splendid asspussy, one I can be proud of.” She then clasped her hands together in front of her chest with her eyes closed and a serene smile on her face, almost as if she was praying. Praying for a new slave and new fuckhole she could use.

Shiga thought, though, wouldn’t Musha notice? Even if his mistress removed the pump and dildo before he woke up, wouldn’t his ass hurt? Wouldn’t he notice his hole getting puffier, meatier, and looser as time passed on?

Luckily, she thought of that too.

“Why can’t you just make him your devoted slut this way?”

Shiga came into her office one day, only to see Musha sitting on the floor in front of her laptop, naked from the waist down and his legs spread. He had headphones over his ears, a blank look in his eyes, and between his legs rested a small fucking machine, drilling a dildo into his ass with no reaction.

“Because hypnotism doesn’t work that way.” She pouted. “Nao-chan, you’re so impatient! Even with my special sci fi book hypnosis, it still took over a year of it, nightly brainwashing, and drugs to get you to this slave state.” She sighed, crossing her arms. “Besides, it wouldn’t be fun if I could instantly enslave him. I want him to think he’s becoming a slut himself.” Shiga quietly apologized to her before he went over to where his friend was, waving a hand in front of his eyes. No response, naturally, as hypnotic lights flashed on the screen.

“So what’s he doing here then? If you’re not enslaving him?”

“Removing his awareness and memories.” She sighed, shaking her head. “He keeps figuring out that something’s going on. It’s because he’s so close to you. So he confronts me about it, and I have to hypnotize him to make him forget he saw anything! Such a headache, but it has to be done.” She then perked up, her sour mood gone in an instant. “The awareness thing is really fun, though. He’s completely unaware of anything sexual happening to him!” That seemed to be the case, as Musha didn’t respond in the slightest to his pussy being rapidly gouged out by a dildo, the machine whirring about, but Shiga was intrigued to see this play out while he was lucid.

And Shiga loved to watch it play out. With every session, the dildo in the machine got wider, stretching him out further. Whenever they went somewhere to sit and chat, Shiga set a dildo down on the seat beforehand, which Musha’s cunt swallowed with ease. He didn’t even realize his pants had been cut to allow entrance. As the months went on, those dildos only got larger, more monstrous, and it made Shiga so horny when he saw his friend’s hole easily stretch to accommodate them with no resistance. God, those toys were so big he could see them bulge through Musha’s stomach! Though his own ass was stuffed 24/7, he couldn’t help but clench down on the toys inside of him when he saw it happen. And soon after they parted, he hurried to his mistress’ office to beg her to fuck him.

After Shiga’s little… inflation incident, the Librarian decided to work on the hypnosis field collar. She worked tirelessly at it while also making time to mess with her slaves and scheme, though no time to do her actual work, and eventually, she managed to get rid of the ten minute time limit entirely. As a special gift, she made it so that Shiga and Ton were unaffected by it. After all, they were already her slaves. They didn’t need to be kept unaware.

So now not only was Musha unaware of what had been done to his asshole, but nearly everyone else was too. Musha thought the collar was so cute when Shiga gave it to him as a present. It had little hearts on it, of course he wore it! This came in real handy when he walked around the library with his pants torn, his sloppy pussy on full display.

“Wow…” Ton mumbled, staring with awe at Musha, who was planting flowers with Yuzuru in the courtyard. He had on overalls, but the seats of those were cut open as well, showing what months of diligent progress had done. Even when he was standing upright, the rim of his asshole was so swollen and huge that it kept his asscheeks from coming together. His hole was still gaping a little, and they could just tell his insides were soft and wet. “Musha-san’s pussy looks amazing~”

“Doesn’t it?” Shiga had to take deep breaths to calm himself. “I wanna shove my cock in him so bad-”

“You can’t, Shiga.” Ton lightly slapped his arm. “Shisho-san said no, remember?” Shiga scowled at that, lightly slapping him back.

“Oh what do you know?” He rolled his eyes, getting a little petty smirk from his fellow slave. “You’re just a breeding bitch. She doesn’t even love you, she just likes getting you pregnant.”

“She loved me enough to give me parts so she could get me pregnant.” He winked, patting his swollen stomach, which was hidden by his hoodie. He loved Ton dearly, but he got on his nerves so bad sometimes! Still, any animosity he had faded when he saw Musha going about his work with his pussy out.

“Hey Igo…” He mumbled. “Let’s go back to my room, I’m really fucking hungry.” Ton blinked at him, before a knowing smile crossed his lips. Shiga wanted to eat pussy? He could eat Ton’s pregnant pussy any day of the week.

“He’s making so much progress…” Shiga had shown up in the Librarian’s office during one of Musha’s hypnosis sessions, though this time nothing was fucking him. He still had his legs spread, staring at the screen blankly, but his meaty cunt lay bare, now larger than any pussy.

“Ah, I was waiting for you to show up, sweetheart.” The Librarian got up, going over to give him a hug which was eagerly returned. She let go, going back to her desk. “I’m starting on my final treatment for Musha-chan before he’s ready to finally become corrupted!” She did an excited little twirl, and it was impossible for Shiga to not share her enthusiasm.

“What is it, Mistress?!” She opened up a drawer in her desk, proudly taking out a small device. It was long, with one end curved into a hook, and the other end being much thicker. On the interior side of the thicker end, there was a little raised section that was itself indented. It reminded Shiga of one of those G-spot vibrators that she used on Ton sometimes.

“This beautiful thing is going to suck on and massage Musha-chan’s prostate~” She cradled the device, almost as if it were her child. “Make it bigger, more sensitive… everything needs to be in place for when he finally falls and accepts how much of an anal slut he is.” A super sensitive, enlarged prostate? Shiga was kind of getting jealous, but he couldn’t tell her that. If he behaved, she might let him eat Musha out once he was enslaved. She took another toy out from her desk, a large plug with a deep groove on one side, and went over to where her slave in the making was.

The prostate massager went in no problem, hooking up and around his meaty rim so it didn’t fall too far in, and then she shoved the plug in, the groove being filled by the narrower end of the massager. They fit together as a set. With that, she turned the massager on, and a faint buzzing noise came from him.

“He’s going to stay here for 24 hours,” She reported, “so that it has time to work.” Shiga nodded, though he couldn’t fight the jealousy that was bubbling up in his heart. Why did Musha get to have all this training without being conscious enough to appreciate it?! Sure, Shiga was fully fucked, modified, and trained to be a proper sex slave, but he wanted more! He missed it!

“Hey Mistress, I was wondering if maybe you could…”

Shiga was so comfortable as he let the hypnotic lights wash over his mind. He was next to Musha, resting with his chest to the ground and his ass up, where his own loose asshole was being plowed by the Librarian.

She was so good to him, he was lucky to obey and serve her.

It wasn’t for another two weeks before all her diligent work started paying off.

It just happened one day. Musha was showering to clean himself off in the morning, humming alone as he felt well rested as always. He had a busy day ahead, so he had to get nice and clean! He took the soap bar, which had been replaced by a new one just the day before, and started rubbing it over his body to lather himself up. Arms, stomach, legs… eventually he ran the soap against his behind. Sure, he probably shouldn’t use the full bar to clean back there, but he’d rinse it off after, so it’d be fine! It was soap! He slid the bar between his asscheeks-

Musha’s eyes shot open wide as he felt the slightest pressure push the entire bar of soap into his rectum.

Eh?

What the hell just happened? He was just holding the- there was no way-

His fingers went to touch his asshole, expecting his usual, tight sphincter. What he found instead was his fingers gingerly touching the edge of something huge. That couldn’t be his asshole, that had to be something else! And yet, he could still feel the bar of soap comfortably resting inside of him. He didn’t know what had happened to him, but he still had to get it out! He grimaced, bracing himself before he stuck a finger in. He couldn’t feel the finger inside him at all! The bar of soap was too large to get out with just a single finger, so he cautiously stuck in a second… then a third. Still no resistance, and the bar was just out of reach.

He could try and figure out how this happened to him later, for now he just had to-

His entire hand easily slipped into his cavern of an asspussy, where his fingers wrapped around the bar of soap. Maybe it was just his confusion about his situation, but he felt some kind of dull tingle in his brain as he withdrew his hand, washing off the bar of soap and setting it back. That… large bar of soap was just inside his asshole. His entire hand was inside his asshole!

Still… now there was soap inside of him which he had to wash out. Taking a deep breath, he slowly inserted his hand back inside himself, wincing despite there being no pain involved, just the slightest feeling that he was being stretched. He rubbed the leftover soap against his inner walls, which were incredibly squishy, before he felt it.

A large lump.

Just running his fingers again made his brain tingle again, but this time it was stronger.
More arousing. He continued to stroke the lump, and to his surprise, his dick started to harden. Was this… was this turning him on? But he wasn’t even touching his penis. He wasn’t one to masturbate usually, but he at the very least knew how that worked.

Still, the more he stroked himself from the inside, the harder he got… before he decided to press down on it.

An involuntary moan left his lips as his head flew back, his dick spurting all over the shower wall and leaving Musha panting, his hand still in his ass.
That… that felt amazing. He never knew masturbation could feel like that, the electric tingles of pleasure still racing across his brain and down his entire body.

He eventually left the shower and got back to his room, though he stayed undressed for now. He stood in front of his full body mirror, completely naked. Yep, he looked normal! However, when he started turning to the side, he could see something poke out from between his buttcheeks! Reaching back, he pulled the closer cheek to the side so he could get a better look.

His hole was just as big as it felt in the shower. Running around 8 cm along his crack, that wasn’t even counting the swollen flesh that surrounded it! From how he pulled his cheek to the side, the hole easily opened, showing his innards to its audience of one. Musha stared, transfixed by the sight.

Carefully, he squished the outer ring in his hand, and he gasped out in pleasure. That felt so… so good. Not as good as whatever that lump was inside him, but he just…
It felt like a vagina, almost. A huge, puffy vagina instead of a butthole. A vagina meant for… sex.

Would sex feel good with this? He couldn’t help but wonder. He got down onto his knees, putting his head to the floor so he could see his reflection between his legs. Now, he could use both hands to spread his cheeks, and-

He was so big… and it felt so good. Maybe it was a good thing that his hole had turned into a pussy. He should… he needed something in it.

Musha’s mind was getting clouded by lust as he looked around his room for something he could put up his ass. Sure he had his hand, but that barely felt like anything! And then, his eyes rested on a 2L bottle he kept in his room. He liked to fill it with water or cold tea, anything for him to drink if he got thirsty in the middle of the night. But now, all his muddled mind could think about was feeling it penetrate him.

Setting it on the floor, he considered the best way to go about this for a second before he decided to squat down over it. The cap slipped in no problem before the neck of the bottle got wider… wider…

The stretch he felt was enough to make his eyes roll back in his head and another moan to leave his lips. Why hadn’t he done this before?! It felt heavenly, especially as it started to rub up against that lump inside him. He just kept going, his squat growing deeper as more and more of the bottle penetrated him. Sweat ran down the sides of his face as the bottom of the bottle finally disappeared inside him.

Shakily, Musha stood up, though his legs threatened to betray him. He could only stare at the mirror with wide, slightly crazed eyes. It… it was inside him. It was all inside him. He could see it in his stomach, the side of the bottle poking out. He couldn’t believe he’d done something so crazy, but he had. And it felt amazing. He couldn’t take it out now… now that he knew this pleasure existed.

knock knock Musha froze as there was a knock at the door.

“Musha?” Shiga called from the other side. “You awake? Come on, breakfast is gonna get cold!” Shiga couldn’t see him like this! Musha hurried around to get dressed, the waves of pleasure from the bottle inside him assaulting him with every movement.

“Yeah I- ohhhh~” He covered his mouth to keep his moans down, stopping for a second so he could properly answer. “I’m just getting dressed! Overslept, silly me!” He put on a loose hoodie to cover the bulge in his stomach, putting on his pants as well as the cute heart collar that Shiga had given him as a present. He couldn’t believe he was doing this. Going to get breakfast with his best friend while he had such a loose, sensitive sex organ and an entire bottle inside him.

“Y-Yeah… I’m here, sorry.” Musha opened the door, his legs still shaky as he had to bend over and hold onto the door tight to keep himself up. Shiga tilted his head in mild concern.

“You ok there?” He asked. “You feeling weird again?”

“Yeah… maybe I’ll go see Mori-sensei later.” Not with a bottle inside him, he wasn’t! Shiga took his arm to support him as the two of them started heading to the dining hall. As they walked, however, Musha felt something… something start to slip.

His asshole was so loose that the bottle was starting to slip out.

He started to internally panic, but realized he was wearing pants. As long as it didn’t stick out too much, he could discreetly shove it back inside himself.

Holy shit, Shiga thought, as he saw Musha’s asspussy part and the bottom of a two litre bottle start to be pushed out. Did he put that in himself?! Shiga looked around, though of course no one paid them any mind or noticed what was going on. No wonder Musha seemed so weak… he’d finally caught on to what happened to him. While he wouldn’t notice sexual things done to him, it was only a matter of time before he himself discovered it.

He wanted to put a hand on the bottle, shoving it back inside him, but he refrained. It was better watching Musha’s panicked expressions. He realized the bottle was slipping, but not that Shiga had a full view.

Musha asked Shiga to pick them both up some breakfast as he sat down on one of the chairs, sighing in pleasured relief as the bottle was now fully back inside him.

As Shiga went to get them some food, he discreetly took out a small phone, shooting the Librarian a quick text.

It was time to enslave him.

After breakfast, it was time. Shiga could hardly wait. They had finished up, taken care of their plates, when Shiga finally addressed his friend.

“Hey Musha,” he started, “can you come with me for a bit?”

“Ah… sure?” He seemed confused, and a little scared. Anyone would be scared if they found out they had an absolute cavern for an asspussy and had a huge bottle shoved within them.

The two of them walked together, Shiga holding his hand, leading him along. They were so close, he could barely contain his excitement. The two of them entered the Librarian’s office, Shiga locking the door behind them to make sure no one would interfere. Inside was the Librarian herself, of course, as well as Satomi Ton.

He got the news as well, and of course he couldn’t miss this.

“What’s this about…?” Musha nervously asked, wringing his hands. “Oh Satomi-kun, hi.” This got him a cheery wave back.

“I called you here because I heard some wonderful news!” She clasped her hands by the side of her face.
“I heard you finally realized how much of a slut you were!”

How much of a slut he was… how much of a slut…

“H-Huh?!” He squeaked, his brain not really processing what she just said as his face went bright red. “I’m not- I’m not a-”

“You’re not?” She asked, innocently blinking her eyes. “But your pussy’s so huge and you’re walking around with it out in the open… if you’re not a horny slut, why are you walking around with such a huge thing inside you?” Shiga finally rubbed his hand against Musha’s ass, before it slid into his crack.

“Shiga?” Musha looked over at him with wide, fearful eyes. “What are you-” In one motion, he slipped his hand deep within his ass, grasping the bottle and pulling the entire thing out. It was too much for him as Musha came, creaming the front of his pants as his legs gave way. Shiga caught him with his other arm, handing the bottle over to the Librarian.

“Look at this!” She gasped, holding the whole thing up. “It’s so thick, and you didn’t use lube at all! Your slutty, wet pussy just gobbled it up!”

“I…” Musha started to sob from how overwhelmed he was, his asshole still gaping from the bottle being pulled out so suddenly. “I’m not a slut… I don’t know what happened to me…”

“Well that’s easy!” Ton chirped, coming around to put a hand on his head, gently ruffling his hair. “Our mistress blessed you with a big, sloppy, boypussy because she saw your potential. She knew you were an anal slut.” Musha blinked up at him in fear, tears streaming down his face.

“M-Mistress…?” The Librarian gave a set of double peace signs as well as a happy little smile. “You… you did this to me…?”

“Oh calm down.” Shiga dropped him, Musha falling on his ass, still in shock, though he felt the lips of his asspussy rub up against the floor. “It’s not her fault, we were always sluts. She just wanted to make it easier for us to be sluts.” With that, he undid his pants, taking them off and revealing the lower half of his modifications. His huge dick, his swollen balls…

“Shiga, you…” Musha’s world was unraveling. He was going to break as he lay quivering on the floor.

“Yeah, you see this thing?” Shiga pointed to it. “Mistress gave it to me, but that’s not all.” He turned around, putting one leg up on the chair so Musha could not only see his fat ass, but also his asshole, which was plugged up.
“Shoulda gotten you one of these to keep the bottle in.” He pulled it out, setting it on the desk, before he pulled his asscheek to the side, showing Musha his own gape.
“Full set of anal beads in there too.” He bragged. “But my pussy’s nowhere near as developed as yours. You’re super lucky, Musha, to have such a delicious thing.”

“I have a pussy too, but like… an actual pussy.” Ton remarked, taking off his own pants and sitting on the desk, spreading his legs to show off both his holes. “It’s… it’s real loose in there.” He stuck in two fingers, jiggling them around as juices leaked from him. “Mistress pumps me full of babies, isn’t that wonderful?” Musha was frozen in place, tears still streaming down his face in two rivers. His best friend… and Satomi-kun… he was so young, so hopeful. What did she do to them…? And to him?!

“Mushaaa… I’m telling you not to worry about it!” Shiga put his hands on his very wide hips. “You’re just one of us, and it’s great! Let me tell you, I’d die if I couldn’t service her anymore. She just worked your pussy because she saw your potential! She might have loosened you up, but who shoved an entire bottle up his ass and went outside with it?!” Musha stared down at his lap. He did… he penetrated himself with that bottle. And before all this, besides the confusion, his huge hole was so pleasurable. He came from it alone.

… maybe he was like them. Maybe he was a slut.

“I’ll tell you what.” The Librarian finally cut in. “I love my beautiful slaves dearly, but I’m not going to force you, sweetie… I’ll give you a choice.” Musha’s head perked up at that, but he was still silently crying.
“You can leave now, and I won’t make you one of my beautiful slaves. Your pussy will return to a more or less normal state with time if you leave it alone. Or…” She was such a petite woman, so dainty and soft looking wearing a cute pink and white plaid dress. However, she lifted up her long skirt… revealing one of the largest penises he’d ever seen. Betraying her stature, this thing reached down to her lower thigh while flaccid. Thick and girthy with well defined veins, it looked too big for her to jerk off with one hand.

He was transfixed by it, almost hypnotized.

“Or you can get a proper taste of this in your hungry pussy, and swear yourself to be my slave.”

“Mistress’ cock…” Ton gasped, starting to salivate on the spot as Shiga’s dick started to stiffen just from the sight of it. He wanted to ask her right then and there to plow him, but this wasn’t the time. Taking a deep breath, he took the plug back, shoving it between his cheeks to temporarily satisfy him.

Musha stared at it with wide eyes, especially as she approached him, moving her phallus to the side so Musha could get a good sense of her balls. Huge, firm, full of hot cum… They didn’t smell like normal testicles, but had a strong, sweet aroma that invaded his mind.

With that, she backed up, stroking herself to full mast with both hands, before she sat on the floor, laying back. Her impressive, throbbing cock was there, waiting for him to squat down on it like he did the bottle.

“Your choice.” She offered him yet again. “Leave, and your pussy returns to normal over time, or swear yourself to me, and I’ll make sure you get the most out of the cunt I’ve given you.” Musha shakily got up, looking from where she lay to the door, then back again. He could choose… he could choose freedom so long as he left his asshole alone…

There never was a choice. He wouldn’t be able to leave it alone, now that he knew how easily he could fist himself, shove things inside of him… Shiga and Satomi-kun seemed so happy with their modifications, maybe he…

Maybe he could be happy too.

Her dick was so hot as his puffy, meaty slavepussy enveloped her. It was unlike his hand or the bottle, the radiating heat warming his entire body. A shuddering moan left his body as he sunk down on her length. She wasn’t as thick as the bottle, and yet this was much more satisfying. The veins rubbed up against his walls in all the right spots, the head scraping his insides even deeper than where the bottle could reach. He could barely speak as he finally rested against her crotch, just quickly gasping for breath, his mouth still open.

“So how is it?” Shiga asked, enjoying the sight. “Do you get it now?” He did. His pussy was made for her. He was made for her.

“I-I get it…” He breathed out. Looking down, he made eye contact with the Librarian lying beneath him, and he saw her in a new light. She didn’t cruelly deform him, she just gave him a gift. A pleasurable gift for a slut like him.

“Then you can say it, can’t you?” Musha swallowed, nodding. There was no going back if he did this, but he was already long gone.

“Shisho-san… I’ll be your sex slave so long as you keep pleasuring my butthole like this.” She propped herself up on one elbow, reaching up to tenderly touch his cheek.

“You don’t have a butthole anymore, you have a proper boypussy. You can move now.” Musha nodded, putting his hands down as he started to move his hips. Though he was inexperienced, he was driven by pure pleasure as he gained speed in no time, panting and moaning like a bitch in heat as he slammed her cock in over and over.

“How does it feel?!” She groaned. “Your cunt’s so wet and- oh you’re perfect!”

“M-My boypussy feels so good…” Musha had no more resistance left. He was her loyal sex slave now, as he should be. “I love you, Mistress!”

“This is so hot…” Shiga hungrily watched the scene before them, starting to stroke his cock. “Igo, help me out.” However, Ton looked at him a little incredulously.

“You only want me when you get cockblocked by our-” Shiga didn’t wait, going over to him and plunging into his asshole, immediately overwriting Ton’s mind. “- oh fuck, feels so good…” He moaned, his eyelids fluttering.

The two pairs kept at it until the Librarian finally came inside Musha. He’d never felt anything like this, the hot, sticky bursts of cum painting his insides. He’d cum several times by then, his dick leaking out only water by this point. He was panting hard, still seated on top of her, but eventually, she started to get up. Musha fell over to the side, the Librarian pulling her dick out. There was some cum left on her, and definitely quite a bit left in Musha as he lay there, stupidly giggling from the euphoria of giving in.

“Cleanup time!” She announced, going over to where Ton was, grabbing his hair and forcing her dick down his throat so he could suck on it. She gave Shiga a knowing smile, who returned it with a hopeful gasp. Was it finally time?!

“Go ahead and eat, sweetie. You’ve earned it.” Shiga wasted absolutely no time, scrambling to where Musha was and rolling him onto his stomach.

“Thank you Mistress I love you Mistress!” He exclaimed in a single breath before he grabbed Musha’s hips, raising them, and finally dug in.

The taste was heavenly. Something unique to Musha as well as the distinct taste of his mistress’ musk… he was made to be one of her slaves. His tongue plunged deep inside him, though his hole was so large that not only his tongue fit inside, but his lips and nose too. The swollen outer rim cradled his cheeks as he lapped at Musha’s inner walls, trying to swallow up as much cum as he could. Grabbing Musha’s asscheeks, he spread them apart in a desperate attempt to let him dive deeper in. Heavenly taste, erotic scent… and Musha whimpering and moaning as he was eaten out was music to his ears.

“S-Shiga…” He gasped out, before giving another weak moan. “Y-Your tongue…”

He finally pulled his face away for a bit, but he wasn’t nearly done. Putting his lips to a section of that puffy outer rim, he suckled on it, biting down to swell it up with more arousal. If the Librarian’s fat cock didn’t get Musha addicted to the feeling of his cunt, then Shiga’s work would.

Licking it, sucking different parts… He put his hands outside that outer rim, pushing them together to bunch the rim up and make it truly bulge, then pressing his lips to it.

Mushanokouji Saneatsu was a slave to Takahashi Nausicaa… and a slave to his own gaping cunt.

That night, the Librarian was in bed all snuggled up under her fluffy duvets with all three of her slaves. They wanted to spend the night with her to celebrate Musha’s indoctrination. Her dick rested comfortably inside Ton’s pussy as he rested with his head on her chest. Shiga and Musha slept on either side of her, Musha’s dick locked away in a chastity cage. He wouldn’t need his dick ever again, not when he could focus on his pussy.

Both of them slept with enormous plugs inside of them to keep their holes nice and stretched, as Musha was starting to feel itchy if he was empty for too long…

And all of them were happy to be her slaves.
