*KIN-KON-KAN!*
The school bell echoed throughout the building, signaling the start of lunch break. The distant, lively sounds of students moving through the corridors began to seep even to the back of the school.
Meanwhile, behind the school building, Ren finally released his grip on a completely exhausted Yuki.
"Lunch break already? Well then, let's end it here for now."
His tone was casual, as if they had just finished an ordinary conversation, not an intense sexual session. Ren pulled up his pants and straightened his uniform as if nothing had happened.
"Uwoeeekkk..."
Still slumped weakly on the ground, Yuki could no longer hold back her nausea. Her body lurched forward as she violently vomited the contents of her stomach.
Digestive fluids, remnants of her morning breakfast, and—most embarrassingly—the thick white fluid from their "activity" that she had swallowed all came rushing out together.
"Ugh, disgusting..."
"Cough... Cough... You're so rough! Whose fault is it that you made me swallow all of it?!"
Yuki wiped her mouth with the back of her hand, glaring angrily at him.
She pulled up her sweat-soaked shirt, revealing her slightly but clearly bloated stomach.
"Look at my stomach! It's so swollen, like I'm pregnant? Thanks to you, I've lost my appetite—I don't need lunch at all."
"Ahem, I admit I went a bit overboard." Ren shrugged, showing no real remorse.
"A bit? You call that a bit?" Yuki's mouth twitched. "You don't know the meaning of restraint, do you, Ren?"
Seeing his expression remain completely unrepentant, Yuki decided to stop arguing. She redirected her energy to pressing on her still-full stomach, trying to expel the remaining traces of Ren's fluids from within her through her lower body.
It was a slow and humiliating process, but better than feeling bloated all day.
"In that case, I'll head to the cafeteria first." Ren said, ready to leave.
"Go ahead." Yuki grumbled, no longer caring about him. "I'd just be worried you couldn't control yourself and attacked me again."
Ren had already turned away, but paused briefly. "Don't take too long, Yuki. Be careful someone else doesn't find you. It wasn't unlikely for students to come here to hang out, smoke, or even confess their feelings. If a boy saw you half-naked like this, you know what would happen next, right?"
Hearing that, Yuki's hands froze. She stiffened, suddenly aware of how vulnerable her position was.
"Of course I know. They'd record me with their phone cameras, then threaten to spread the footage throughout the entire school unless I obeyed their indecent demands. That's the standard doujin scenario."
"Good, you understand." Ren said flatly. "If that ever happens, our relationship ends. You know I don't like used women."
Without waiting for a response, Ren finally walked away, leaving Yuki alone behind the building—her body still disheveled, her emotions in turmoil.
"He didn't even stay to keep watch in case someone came." Yuki muttered to herself, irritation rising. "Seriously, he just leaves like that with no sense of responsibility. What's so great about a scumbag like him? I don't understand how Masha-san could like him and be willing to carry his child?"
Shaking her head, she tried to make sense of it.
"Could it really be true that love makes girls stupid?"
To Yuki, her relationship with Ren was purely physical—friends with benefits. She knew full well his selfish, depraved nature. That was precisely why she was so confused about how a good girl like Masha could fall in love with him and even agree to bear his child.
"Whatever, who Masha-san likes is none of my business."
Yuki decided not to dwell on it.
"Just get that man's seed out before someone shows up."
So she refocused on her unpleasant task: cleaning herself as quickly as possible before anyone found her in this embarrassing and potentially ruinous state.
Each pressure on her stomach felt like a reminder of the risks she'd taken by getting involved with someone like Ren.
◆━⊰✧⊱━◆
In the cafeteria, many students were already eating with their friends. With a tray holding a bowl of curry rice in hand, Ren scanned the crowded room, searching for an empty seat.
Finally, his gaze landed on a relatively quiet corner. There, Masachika sat alone. Ren walked over and smoothly took the seat across from him.
"Did your stomach get better, Ren? You even skipped class. Hiratsuka-sensei wasn't happy about a student skipping on the first day. Even when I gave her your excuse, she didn't believe you spent hours in the bathroom. Well, I don't believe it either."
Masachika informed him of the bad news—that Ren had to report to the teacher's office to see Hiratsuka.
Ren scooped a bite of curry rice, completely unfazed by the news. He confessed casually, his voice low enough not to be overheard.
"Yup, the bathroom excuse was a lie. Actually, I was having sex with a girl behind the school building."
Masachika nearly choked on his drink. He set his glass down a bit too hard.
"Seriously? Do you have a girlfriend now?"
"She's not my girlfriend. We're just FWB. Basically, she's just a slut who craves me to satisfy her. If she gets pregnant, I don't have to take responsibility."
Of course, Ren wasn't worried about pregnancy. First, as a Campione, it was extremely difficult for him to impregnate an ordinary woman. Second, Yuki had a medical condition that made it very hard for her to conceive.
"There are girls like that? Tsk, you're just showing off, aren't you? Lucky bastard."
It was just a joke. Masachika wasn't the type to be envious or to casually sleep with random women. He believed in pure love and meaningful relationships.
"Look. Here's her photo."
Suddenly, Ren pulled out his phone. With a few taps, he showed Masachika a photo he had taken just moments ago.
The image showed a girl with long, flowing brown hair. Her shirt and skirt were open, revealing her full breasts covered in hickeys and her cleanly shaved pubic area. Her hands covered her eyes, as if shy—but in contrast, her tongue was sticking out in a shamelessly lewd ahegao expression. The background was blurry, but clearly taken in a hidden spot.
"Huh? Ren, do I know this woman?"
Masachika frowned. He felt the girl in the photo looked familiar.
(Of course you know her—she's your little sister!) Ren thought internally, immensely amused. But outwardly, his face remained neutral.
"Not sure." Ren said, putting his phone away, pretending to be indifferent. "Maybe you've passed her in the hallway or something. That's why she feels familiar."
Masachika nodded, easily accepting the explanation.
"You might be right."
His mind would never drift to the idea that the girl so lewdly displayed in the photo was his own younger sister, Suou Yuki—the very same girl known as a polite and elegant Student Council member.
Even in his wildest imagination, he never suspected Yuki could become such a slut as shown in that photo.
