Seiji reflected.
Watching his naked sister through the crack in the door, he was overwhelmed by memories of their past together.
‘Nyah-nyah, Seiji is a weakling~’
‘Hey, I’m not a weakling!’
‘Oh really? You can’t do anything without your big sister, you little squirt~’
A weak and helpless boy.
That’s how he was defined back then, and the tough girls always teased him for it.
Meanwhile, the other boys envied the attention he got from girls and gossiped about his looks.
‘Getting attention from girls again.’
‘So what if he’s pretty?’
‘Ugh, he’s so annoying. Total turn-off.’
No one among his peers welcomed him.
For a young, sensitive boy, it was hard to endure, and so Seiji’s eyes were rarely dry.
‘Sniff, Mom, Dad...’
‘Haha, look at him crying again.’
‘Seiji’s a crybaby!’
Even his tears of frustration became something to mock, and the cycle of misery repeated.
But not all cycles last forever.
Even in such a harsh environment, there was one person who always stood by him.
‘Hey, you guys! You’re picking on Seiji again, aren’t you?’
‘Ahh, it’s the gorilla! Run!’
‘Who are you calling a gorilla!? Hey! Get back here!’
Senya. His one and only sister.
Unlike Seiji, she was strong in both body and spirit, and her arrival made the neighborhood kids scatter in fear.
Once things quieted down, Senya always comforted Seiji.
‘Seiji, are you okay?’
‘Sniff, sis, sis...’
‘Good grief, you really are a crybaby, aren’t you?’
She wiped his tears, patted his head, and spoke gently.
But even then, Seiji couldn’t stop crying easily.
Even if the bullies left for now, he knew it would just happen again.
‘Am I... wrong?’
‘Wrong about what?’
‘For being born weak... Is that why they pick on me? Is it wrong to cry all the time?’
He hadn’t chosen to be a weak boy. Was just being born such a sin?
Looking back, it was sad how much shame he carried from such a young age, but even then, his sister never abandoned him.
‘You always worry about pointless things, Seiji.’
‘Pointless...?’
‘No one in this world is wrong just for being born. Everyone is born and grows up differently. Being different isn’t wrong.’
Seiji remembered.
That gentle whisper of advice, and the rough hand that patted his head.
‘Boys like you are supposed to be weak. But as a boy, you’re also naturally sensitive and considerate. People tease you for being weak, but I think it’s proof you have a kind heart.’
‘...Sis.’
‘And it’s a woman’s job to protect kind-hearted men like you. Just like I always come running when you cry.’
Yes, she always protected him.
If he was bullied, she’d stand up for him. If he was in danger, she’d come to save him first.
She was like a hero from a fairy tale a knight protecting her prince.
‘So don’t blame yourself for being weak. You don’t have to force yourself to stop crying. You were born that way, and I was born to protect you.’
‘...Really?’
‘Of course! Have I ever lied to you?’
He loved his sister for that.
Though the world was full of things to fear, she gave him the courage to live bravely.
‘So don’t worry too much. As long as you’re here, I’ll always protect you!’
That’s why Seiji always relied on his sister, always went to her for advice when he was in trouble.
At some point, he forgot that was out of love, and started taking her kindness for granted.
“Haa, haa...♥”
But even that wouldn’t last forever.
As if to prove it, right now his sister was making sounds he’d never heard before.
Sweating, naked, taking the man he considered his enemy inside her body.
“Ugh, haa... haa...♥”
Why?
Why was the sister who always protected him now being taken by that man?
What had that man done to make her look so enraptured in his arms?
“Does it hurt?”
“N-no, it’s fine. It was tough at first because it’s so big, but I’m used to it now...”
Her voice was full of affection for her partner.
Like when she whispered love to Seiji or maybe even deeper and stickier feelings.
“Hehe, I didn’t realize it yesterday, but this is what a man’s thing feels like.”
“It’s probably different from other men. I’m pretty big.”
“Pfft, compared to my little brother, it’s a huge difference.”
Grit.
Seiji clenched his teeth and fists at being mentioned.
It was humiliating to be compared to him by his own sister.
She said she loved him. She said she’d protect him.
So why was she laughing and chatting with that man, making him the butt of the joke?
What had changed her so much?
“Can I kiss you?”
A gentle whisper that made Seiji’s breath catch.
He saw his sister, blushing and wrapping her arms around the man.
Smooch, mmph.
A kiss, deep and sticky, filled with true affection something she’d never given even her brother.
Thrust, thrust!
Even as they kissed, the man’s hips moved roughly, making her body shake with each wave.
Seiji could only watch, frozen.
He wanted to burst in and stop it.
He wanted to demand an explanation.
But his hand slipped from the doorknob.
And that hand ended up on his own half-exposed, pitifully small member.
‘W-what’s...’
He was hard.
Watching his sister being taken, he felt a physiological arousal at the sight that should have filled him with shame and disgust.
“Aid’s body is really sturdy.”
The more she praised the man, the more his ears rang.
The more the man responded, the more his mind went blank.
“I train hard, after all.”
“Hehe, it feels strange. I’ve always been the one protecting others, so relying on someone like this feels new.”
She showed emotions she never showed to Seiji, compared him to herself, and now even the last privilege he’d had in this world was being taken away.
“But I’m happy, even if it’s just words. I feel like something inside me is finally being filled.”
When she smiled in a way she never had for him, Seiji’s mind went blank, and instinct took over his actions.
“Senya, can I ask you a favor?”
“Huh? What is it...?”
No, don’t do it.
“Call me ‘Master.’”
Don’t play along with him.
Don’t make me any more pathetic than I already am.
“Master? You know I’m a knight of the lord, right?”
“It’s just for fun. Is that okay?”
But even his desperate hope was just an empty echo.
As if responding to a faint hope, she whispered shyly,
“M-master...?”
Crack.
His vision split.
It was as if the world was crumbling, as if his soul was being torn apart.
“Be more specific.”
“Um, like how?”
“Like this...”
The man’s lips touched her ear.
From a distance Seiji never dared approach, he whispered words Seiji never dared ask for.
“M-master...”
And she accepted, opening her mouth.
A proud knight, now shyly uttering words that shattered her pride and dignity.
“Please, ruin this virgin who knows nothing of men tonight...”
“Ugh, mmph...”
He couldn’t breathe.
Afraid his own moans might be heard, he clamped his hand over his mouth.
He didn’t want to be discovered.
But he couldn’t stop.
“Ahh! Senya!!”
As the man’s excitement peaked, he stood up, lifted her, and began pounding her roughly.
“W-wait, this position is too embarrassing... Ah!”
Thrust! Thrust!
“Ah, oh, oh, oh, ohhh...♥”
From above, like a stake being driven in, her breath was stolen by the force.
But he didn’t stop, pushing her harder, not caring how her once-proud face twisted in pleasure.
“Haa, haa. Senya! I’m at my limit can I cum inside!?”
“Ah, oh, ohh... oh...♥”
“I’m cumming inside you!”
With a shout, he moved even faster.
Her ruined face was thrown back as his hips surged.
And then spurt, spurt. The sticky sound of fluids erupting.
“Oh, ohh...♥”
She moaned as she accepted his huge load, and only then did he set her down, smiling in satisfaction.
“Whew, that position is tough...”
“Haa...♥”
Senya trembled on the bed, lost in the afterglow.
Seiji, staring blankly, realized something sticky was on his hand.
Compared to what came from the man’s monstrous cock, the amount was pathetically small...
“So, how was sex while sober?”
Senya, finally regaining her senses, answered in a trembling voice.
“I-I don’t know. It ended so suddenly... but it’s kind of addictive...♥”
“Should we go again?”
“Y-yeah... please...♥”
Were they going to start again?
But Seiji couldn’t bring himself to watch any longer.
A normal man calms down after one release.
Unlike the man who was ready for another round, all Seiji felt was self-loathing for relieving himself while watching his sister’s disgrace.
“I feel kind of guilty. Your brother would be mad if he found out.”
“Hehe, don’t worry about him. I’ll talk to him... Just play along if it comes up.”
“That’s all?”
“Well, he’s an adult. He needs to become independent from me.”
The two of them, focused only on each other, didn’t even care about Seiji anymore.
Unable to bear it, Seiji turned away and staggered off.
He could feel the cracks in his heart giving way to collapse, leaving only fragments behind...
The next day, after being with Senya, she told me with a bitter tone,
“Seiji quit the knight order today.”
“Your brother?”
“Yeah, he just left a letter saying he was going back home... I guess what happened with you really hurt him.”
“...I feel kind of bad.”
“Don’t worry about it. He must’ve realized something.”
She tried to see it positively, but knowing the real reason, I felt a bit uneasy.
They seemed close, but maybe it was too much to put on that show in front of his sister.
Then again, he called me a whore who sells himself, so...
His sister’s a good person, but why did the brother turn out so badly?
“Hey Ei! We’re back”
Just then, I heard a familiar voice at the training ground.
Looking over, I saw Martina and Helia approaching.
“Hey, you two. Did your mission go well?”
“Of course! Any mission’s a piece of cake for me~”
Martina, chest out, radiated confidence.
Then she noticed Senya standing nervously beside me and turned her attention to her.
“Wait, I think I’ve seen you before?”
“I’m Senya of the knight order. It’s an honor to meet the Three Knights, Martina and Helia.”
Senya greeted them formally.
I remembered then that Senya was sort of their subordinate, and Martina frowned as she looked between us.
Then she said,
“Wait, you too?”
“Huh?”
Senya stared blankly at Martina, then looked at me.
Realization dawned, and she turned wide-eyed back to Martina.
“...Wait, you two as well?”
Uh-oh, is this going to be a problem?
As I started to worry, Helia sighed and glared at me.
“Aid, I told you not to be so promiscuous with your body...”
“Uh, haha... It just kind of happened.”
In this world, it’s not exactly respectable for a man to be with multiple women.
But fortunately, Helia wasn’t as angry as I feared.
She cleared her throat and gestured to me.
“We’ll talk about this later. For now, get ready to leave.”
“Huh? Are we going somewhere?”
“Lady Renes has summoned you. It must be about today’s scheduled match.”
Right, it’s finally time.
The third match as a gladiator is about to begin.
