Day six of living together. Early afternoon, Room 405 of Luminous Seikai. Outside the window, towering cumulonimbus clouds billowed and grew. In the air-conditioned living room, Kaito leaned back on the sofa, staring vacantly at the ceiling. *(I'm bored.)* Misaki still had his smartphone. His laptop had vanished from the living room at some point, too. There was nothing to do. "[gentle]Sorry, Kaito. An urgent Student Council message came in. I'll be right back, so be a good boy, okay?" About an hour ago, Misaki had left after saying that. He remembered how, on her way out, she had turned back and fixed him with those golden eyes of hers, as if driving the point home with unsettling intensity. *(Be a good boy... well, it's not like I have a choice.)* Kaito sat up. He couldn't focus even with the TV on. He thought about stepping out onto the balcony, but the windows were fitted with multiple auxiliary locks. His gaze drifted down the hallway. The door to Misaki's room was open a few centimeters. *(Huh? She always keeps it locked.)* Kaito stood up. His heart gave a small, tight thump. Ever since he'd come to this house, that one room had been the only place she'd told him never to enter. The single forbidden territory of the childhood friend he'd grown up with since they were little. Before he knew it, Kaito was standing in front of the door. *(Just a quick peek...)* He pushed the door with his fingertips. The hinges creaked faintly. The room was dim. The curtains were drawn tight, allowing only a sliver of outside light to seep in. And then—Kaito's feet stopped dead. "[scared]What... is this?" Every single wall was completely plastered with photographs. Himself in a kindergarten uniform, laughing while covered in mud. Himself the moment he tripped at elementary school sports day. His middle school entrance ceremony, high school cultural festival, a profile shot of him yawning between university lectures. Every photo had a date and location meticulously recorded. "2015.4.7 Entrance Ceremony, In Front of School Gate" "2019.7.20 Summer Festival, With Friends in Front of a Stall" "2023.6.2 University Lecture Room B, Dozing Off" *(These are all from angles I don't recognize...)* On the bookshelf, more than ten notebooks lined up, their spines marked only with years. "2015–2017," "2018–2020"—he didn't have the courage to open them, but he could see countless sticky notes protruding from the page edges, densely packed with minute behavioral records. On the desk sat a small glass case. Inside were strands of fallen hair, fragments of worn-down pencils, even the cap of a mechanical pencil he thought he'd lost back in middle school. All of it arranged neatly, lovingly, like specimens in a museum. Ten years. All this time, all this time— Kaito put a hand against the wall. His knees nearly buckled. Nausea churned, but his stomach was empty and nothing came up. Terror and confusion swirled together, turning his mind completely blank. *(I have to run.)* Following the thought that finally managed to surface, he turned toward the door— "[gentle]You finally found it, didn't you?" A voice came from directly behind him. He spun around to find Misaki standing there, smiling softly. He had no idea when she'd returned—there hadn't been a single footstep. Her long, glossy black hair gleamed wetly in the dim hallway light. Her golden eyes were narrowed, and only her lips traced a perfect arc. "[scared]Misaki... how long have you—" "[gentle]I was behind you the whole time you were admiring my treasures." She stepped closer, one step, then another. Kaito backed away, but his back immediately hit the photograph-covered wall. "[serious]Let's go to the living room. We need to talk." Misaki's voice was calm. But there was a hardness in it that brooked no refusal. --- They sat facing each other across the living room table. Outside the window, the clouds had begun to thicken before they knew it. The faint rumble of thunder sounded in the distance. "[gentle]Your smartphone, laptop, and your wallet and bankbook. Put them all here." Misaki pointed at the table. She was smiling, but her eyes weren't smiling in the slightest. "[angry]Why the hell should I?! They're mine!" He raised his voice for the first time. It wasn't that fear had turned to anger. It was simply the gut instinct that if everything was taken from him now, there would truly be nothing left—that alone drove Kaito to act. "[gentle]Don't try to run. I don't know what I might do." Still smiling, Misaki headed for the front door. She picked up the key ring and checked each auxiliary lock one by one. With every metallic *click, click*, another path to the outside world was sealed shut. Kaito was speechless. He felt like he knew exactly what Misaki was capable of when she was serious. No—even if he didn't know, he was certain she would do *something*. This was a person who had monitored him this obsessively for ten years without his knowledge. There was no way that kind of fixation would end with mere threats. There was also the guilt of being indebted to her. She was the one who had taken him in when he'd lost his house in the fire and had nowhere else to go. But—more than anything else—the person she was right now terrified him. With trembling hands, Kaito placed his smartphone, laptop, wallet, and bankbook on the table. "[whispers]Good boy." Misaki glanced at them, then stowed them away in her bag. Then she slowly grasped Kaito's wrist. "[gentle]Come. I had no choice. Because you tried to run." As if being dragged, Kaito was taken to the bedroom. --- The moment he was pushed down onto the bed, Kaito's breath caught. Misaki straddled him from above. Her golden eyes glowed like a cat's in the dim room. Her long black hair fell on either side of Kaito's face, covering his field of vision. "[whispers]Until now, I've been gentle with you at night, right? But today is different." Her fingers slipped under the hem of Kaito's T-shirt. Cold fingertips crawled across his stomach, slowly making their way up toward his chest. "[scared]Stop... please, stop it." "[whispers]You can say you hate it. Go ahead, say it. But I won't stop." Whispering that, Misaki gently sank her teeth into Kaito's earlobe. His shoulders jerked at the sensation mixing pain and ticklishness. She peeled off his clothes one piece at a time. When he tried to resist, his wrists were pinned to the bed by one of her hands before he even realized it. Where did such slender arms get this strength—while Kaito was still reeling in confusion, his lower half was completely exposed. Misaki's other hand traced the inside of Kaito's thigh. When his legs tried to move involuntarily from the ticklishness, she pinned them down with her own hips. "[whispers]Kaito, this part of you is already like this." Her fingertips gently touched the tip of Kaito's penis. She slowly scooped up the thread of pre-cum with her finger. Kaito couldn't believe his own body. He was trembling with fear, his heart was pounding sickeningly—yet his penis alone was rock hard. Every time Misaki's fingers touched him, the core of his hips grew hot, and his body begged on its own for more. "[whispers]You're crying. You're scared, but it feels good, doesn't it?" Only when she said it did Kaito realize tears were spilling from his eyes. *(Why... why at a time like this...)* He was pathetic, frustrated, terrified—and yet his body grew hotter and hotter. That contradiction was unbearable, and the tears wouldn't stop. Misaki kissed him as if licking away the tears, then put her fingers in her mouth and wet them with saliva. Then she wrapped that hand around Kaito's stiff, erect penis. "[whispers]I'll make you feel so good. So tell me you'll become mine." Her slender fingers began stroking up and down the shaft. When the pad of her thumb traced the ridge of the glans, Kaito's hips bucked. "[scared]Ah... s-stop..." Even as his mouth refused, his penis grew even harder. Pre-cum overflowed, making the movement of her fingers slicker. Wet, squelching sounds echoed through the quiet room. "[whispers]If you really want me to stop, then resist for real. Shove me away and run. But you can't, can you? Because Kaito is kind. Because you're afraid of hurting me. And besides—" Misaki stopped her hand and brought her lips close to Kaito's ear. "[whispers]It really does feel good, doesn't it?" He couldn't deny it. Misaki's fingers resumed their movement. This time, she gripped the shaft with one hand and began gently massaging his testicles with the other. At the same time, her tongue crawled over Kaito's nipple. Multiple pleasures assaulted him simultaneously, and Kaito's thoughts dissolved into chaos. *(Help me... someone...)* Those were the only words that surfaced in his mind. But he didn't know who to ask for help. His smartphone had been confiscated, and he was so thoroughly stained by Misaki now that he couldn't even recall his best friend's face. "[whispers]Shall we try feeling it deeper soon?" Misaki released her hand and shed her own skirt. She wore nothing underneath. Her secret place was already drenched, love juices trickling down her thighs. "[whispers]Kaito's cock is so hot. This is going to go inside me." She straddled Kaito's hips and pressed the entrance of her vagina against the tip of his penis. The sensation of hot, wet flesh touching his glans sent electricity racing down Kaito's spine. "[whispers]I'm putting it in. I've wanted to do this for so, so long." She lowered her hips. The slick vaginal walls swallowed Kaito's penis down to the base. In that instant, Kaito couldn't breathe. A pleasure incomparable to the handjob from before made the edges of his vision flicker and flash. "[scared]Ugh, ah... aahh...!" "[whispers]Amazing... I can feel Kaito moving inside my stomach." Misaki closed her eyes in rapture and began slowly rocking her hips. Inside her, it was hot and tight, squeezing his penis with a *kyuu kyuu* grip. With every thrust, love juices frothed at their union, and lewd wet sounds filled the room. "[whispers]I love you, I love you, I love you so much... Kaito, become mine and mine alone..." Misaki's movements grew more intense. Rubbing her own clitoris with her fingers, she slammed her hips down again and again. *(I can't... anymore...)* Regardless of Kaito's will, his body raced up the staircase toward climax on its own. Deep in his testicles, everything tightened, and his ejaculation surged upward. "[whispers]Let's come together, okay? I'm about to come... so Kaito, come inside me too." "[scared]No, inside is...!" "[whispers]It's fine. Give it all to me." The moment her vagina clenched in a spasming *gyuu*, it swallowed Kaito's penis to the hilt and constricted. Unable to resist that pressure, Kaito came too. Thick, hot semen pumped against the entrance of Misaki's womb. "[whispers]Aaahh... so warm, Kaito's filling me up inside... I'm so happy..." Misaki collapsed onto Kaito's chest as if crumbling. With his face a mess of tears, Kaito stared up at the ceiling, breathing raggedly. *(It's over... everything.)* Humiliation, terror, and the sweet afterglow that still lingered. Those three things tore Kaito to shreds. --- Just as Misaki closed her eyes in satisfaction— *Click.* The sound of a spare key turning in the front door. "[excited]Misaki-senpai, are you here?" Her silver hair in a short bob swaying, Shiratori Rio entered the living room. But finding it empty, she tilted her head and made her way toward the bedroom. The door was half open. "[surprised]Misaki... senpai...?" Rio's voice trembled. On the bed, Misaki nestled against the naked Kaito's chest. The stains on the sheets and the scattered traces of semen. And their lower halves, still deeply connected. "Oh my, Rio-chan. Perfect timing." Misaki sat up as if nothing had happened. When their union came apart, semen dripped thickly, staining
