Kyouka's heart thudded in her chest like a war drum as she stood in Ren's dimly lit room, the vial clutched so tightly in her hand that her knuckles turned white. The door had clicked shut behind her, sealing her in with her adoptive brother, and the weight of what she was about to do pressed down on her like a lead blanket.
What am I even doing? she thought, her mind spiraling as she glanced at Ren, huddled under his blankets, his wide, wary eyes glinting in the soft glow of the lamp. He looked so fragile, so innocent, and yet here she was, about to… what? Help him? Save him? Embarrass him?
When did they remove their clothes, and why had she asked Ren to lie down on the bed? She had so many questions to ask herself. Wasn't she here to quickly jerk off Ren and collect his semen? So why was she doing all this? To Kyouka, the answer wasn't clear, but as she looked at Ren's chest and his already erect cock, she felt her own love juices dripping onto the floor.
She was aroused by her own adoptive brother.
This is insane. I'm insane. Why did I volunteer for this? Her cheeks burned, and she forced herself to take a shaky step forward, her legs feeling like jelly. I told Mother I'd handle it because I'm closer to his age, because I'm his sister—not by blood, but still. But this… this is too much. I've never even… ugh, why didn't I just let Mother deal with this? She's the adult! She's the one who's supposed to know how to handle these things!
Kyouka's gaze flickered to the vial in her hand, the cold glass a stark reminder of her mission. The sperm bank. The deadline. Tomorrow. If she didn't do this, they'd come for Ren. They'd drag him to the hospital, strap him to some cold, sterile machine, and… No. I can't let that happen. Not to Ren. Not after what that girl did to him.
The thought of that incident at school—some awful girl trying to force herself on him—made her stomach churn with anger. He's been through enough. He's scared of women now, isn't he? And here I am, about to… to… oh gods, what am I doing?
She swallowed hard, forcing a smile that felt more like a grimace. "Ren… it's me," she said, her voice wobbling despite her best efforts to sound calm. Keep it together, Kyouka. You're doing this for him. For his sake. You're his sister. You're supposed to protect him. But the words felt hollow in her head. Protect him? By… by doing this? Her face flushed hotter, and she prayed the dim light hid the redness creeping up her neck.
Meanwhile, Ren was having the time of his life, admiring Kyouka's sexy figure. She had curves in all the right places, with her perky breasts looking especially delicious to him under the soft glow of the lamp.
In this world, it wasn't normal for men to suck on a woman's breasts—instead, it was usually the other way around. Ren knew his body was different, though; his sensitivity was far higher than he had expected. He already felt a faint, burning sensation in his balls, as if he were about to cum.
"Kyouka… are you okay? You look stiff," Ren asked, unable to take it anymore. He wanted to feel what a woman's body was like again—something he had forgotten, since he'd never truly experienced it in this body.
Kyouka was snapped out of her thoughts by Ren's voice. She quickly moved toward the bed, each step leaving a trail of her dripping love juices on the floor.
She took a deep breath, forcing herself to meet Ren's eyes. His expression was unreadable, but there was something in his gaze—something that wasn't fear or discomfort. Is he… excited? No, that's ridiculous. He's just… being cooperative.
Right? She cleared her throat, trying to sound professional. "Okay, Ren, like I said, we need to… um… make sure you're… lubricated. For the, uh, process." Lubricated?! Why did I say it like that?! I sound like a freak!
Ren tilted his head, his lips twitching like he was fighting a smile. "Lubricated? How exactly do we do that? Did you bring any lotion?"
Kyouka's brain short-circuited. Lotion?! Does he think I'm going to slather him in moisturizer?! "N-no! I mean, not lotion! I mean… you know, natural… stuff." She gestured vaguely, her hands flailing like she was trying to swat away her own embarrassment. Natural stuff?! What is wrong with me?! "I mean, I'll… I'll help you get… ready. That's what foreplay is for."
Foreplay. I just said foreplay to my brother. I'm going to die. She squeezed her eyes shut for a split second, praying for a lightning bolt to strike her down. When none came, she opened her eyes to find Ren watching her, his expression still infuriatingly calm.
How is he so okay with this? Oh gods, what if he's just pretending to be fine to make me feel better?
She scooted closer, her knees brushing against the edge of the bed, and her heart felt like it was about to explode. Okay. Just… touch him. Gently. Like in the videos. You can do this. You're not going to mess this up. She maintained her facade of a cool elder sister outside and went for it.
She reached out, her hand hovering over his cock, her fingers trembling like leaves in a storm. Oh gods, I'm really doing this. I'm about to touch my brother's… nope, don't think about it. Just do it.
For the sample. For Ren. She glanced at his face, searching for any sign of discomfort, but he just looked… expectant? Is he actually okay with this? Or is he just really good at hiding how freaked out he is?
Her hand finally made contact, and she flinched at the warmth of his skin.
Ohmygodohmygodohmygod.
Her mind blanked, and for a moment, she forgot how to breathe. It's fine. It's just skin. Just… do the thing. She moved her hand tentatively up and down, her touch feather-light, and Ren let out a small, involuntary sound that made her freeze. Was that a good sound? A bad sound? Did I hurt him?!
"Kyouka?" Ren's voice was soft, almost teasing. "You okay?"
Me?! Am I okay?! You're the one who's supposed to be freaking out! She forced a laugh, high-pitched and nervous. "Y-yeah! I'm fine! Totally fine! Just… making sure you're comfortable!" Comfortable?! He's naked on a bed with his sister's hand on his… oh gods, I can't even finish that thought.
She resumed moving her hand, trying to mimic what she'd seen in those blurry, awkward videos she'd watched in secret. This is fine. This is normal. Well, not normal, but… necessary. For the sperm bank. For Ren.
But as she continued, something unexpected happened. Her panic started to fade, replaced by a strange, tingling warmth in her chest. Wait. Am I… enjoying this? The thought hit her like a freight train, and she nearly yanked her hand back.
No! No way! This is for Ren! I'm not supposed to feel… whatever this is! But the more she focused on him—on his steady breathing, on the way his body responded to her touch—the harder it was to ignore the heat creeping up her own body. This is so wrong. I'm his sister. Well, not really, but… close enough! What is wrong with me?!
This went on for a few seconds, until Ren suddenly felt the dreading feeling of ejaculation.
"HUH? WHAT...it hasn't even been 1 minute why do I feel this? NO WAY!" Suddenly the dreading realization came to Ren.
The men in this world don't last long and are not sexually active, which means he is one of them.
Ren didn't have time to think before he felt the hot breath of Kyouka's face drawing close to his shaft, her expression enchanted. Suddenly, he exploded, releasing a load of cum onto Kyouka's face just as she was about to lick him.
"Ahhh~" Kyouka gasped, snapping out of her daze at the cold sensation on her skin. She quickly grabbed a vial and began collecting every drop of semen from her face. After sealing the vial, she dressed herself and decided it was time to end this—her job was done. It was going to be a long night for her, but she didn't want to force Ren into anything.
"Good night, Ren! Don't think about anything. You're the cutest and most adorable brother one could have—we all love you." Leaving those words behind, the still-aroused Kyouka left the room, breathing heavily and holding her face as the scent and taste of his semen lingered.
"Hold back… hold back… He's my brother…" she muttered to herself while walking away.
Ren, still in shock and disappointed with his performance, stared blankly until Luxy appeared beside him, holding her forehead.
"Now do you understand why this world is dangerous? If a woman forces you, you could easily die from sex. You're the victim in this world, and they are the predators," she said quietly.
Ren finally turned to Luxy, his voice steady despite the lingering shock.
"I need those powers! I need to be strong! I can't have this body… I need to get stronger."
