"Eep! I—I'm going to the bathroom! You guys, why the hell are you spamming 'cheers' in the chat!?"
Inside the room, Sagiri was sitting in her pink pajamas on the carpet, drawing on her tablet for a livestream. Her bare feet were like white jade—small, tender, and incredibly tempting. Sagiri was hyper-vigilant about the sound of her door opening; after her instinctive shriek, she realized it was Rin Ito and quickly muted her microphone.
"What are you doing here? I said I wasn't going to the convention!"
"Can't I come see you anyway?"
Rin stood behind her, smiling. On the screen, her Live2D avatar shook. Rin glanced at the chat; it was a waterfall of "Cheers!" (a meme for when a streamer leaves their desk). Eromanga Sensei had massive popularity, and now that fans knew the voice belonged to a genuine flat-chested loli, her viewership had skyrocketed.
Rin hugged Sagiri's tiny body from behind. His hand slid under her pajama top, gliding over her smooth belly and ribcage before settling on her two small, ruby-red nipples. Sagiri wasn't wearing a bra; at her size, there was no point.
With a gentle flick of his fingers, Sagiri slumped back into his arms, her face flushing. "W-wait until the stream is over..."
"Shh... keep it down," Rin whispered, nibbling her ear. "The walls are thin. If you make too much noise, your brother will hear. Besides, he's watching the stream right now. Maybe even your aunt is too."
"Then... then get away! I can't draw like this!" Sagiri hissed. On a normal day, she'd be shouting, but now she had to suppress every sound.
"But you're already getting wet."
Rin's hand slipped into her pajama bottoms. Her sensitive body produced nectar with the slightest provocation. He looked at the chat; fans were betting on whether the "loli streamer" would wash her hands after the bathroom break.
"Your fans are getting impatient."
"Pervert!!" Sagiri bit his hand before opening her mic with a face full of indignant shame.
"I was gone that long because I was washing my hands! Of course I washed them! And stop spamming 'cheers'!"
She spoke with a textbook tsundere tone. When she turned to glare at Rin, her avatar captured the movement perfectly. The chat exploded with: Is someone there with the streamer? Rin reached out and adjusted the tracking camera. Since Sagiri was so small, he could rest his chin on her head, and the camera would only see her face.
He gently toyed with her nipples. Since it was live, he didn't dare go too far... yet.
For Sagiri, it was incredibly thrilling. Last time at a convention, he had stuffed nearly ten vibrating eggs inside her! She wiggled her bottom against Rin's lap. Memories of being played to climax in public made her heart race, and the dampness between her legs intensified.
As Sagiri chatted with her fans and drew, Rin quietly stripped her of her pink pajamas and cute blue-and-white striped panties. He undid his own pants and lifted her onto his lap.
"Why don't I draw big breasts? Because big breasts are a lie! This world is a scam; they're all padded!" Sagiri ranted to her chat. She realized Rin wouldn't do anything truly "over the top" because of her brother downstairs. Since she felt safe, she got bold.
She rubbed her legs against his, occasionally reaching back to stroke the hard length pressed against her. "" (Sumata/Thigh-fucking) didn't offer the most physical stimulation, but the psychological thrill of doing something so "bad" in front of thousands of people made her inner thighs slick with sweat.
Rin's hands didn't stop. Even though her chest was nearly flat, the nerve endings were dense, making her more sensitive than a girl with a large bust. The fans in the chat and the brother downstairs had all become part of the "play."
"!!!!!"
Sagiri bit her lip hard to keep from screaming. Her thin thighs shook like a leaf. After a long moment, she let out a shaky breath.
"T-that's all for today's stream."
The moment she hit the peak, she killed the broadcast. She turned around and smashed her lips against Rin's. The sound of wet kissing filled the room.
After a long kiss, Sagiri adjusted herself. She didn't need help aiming like Kaguya did; she rubbed against him briefly before sinking her hips. Her small, tight body was stretched to the limit. The sensation of being torn open—and then filled—made her arch her neck and shiver.
"Haa... haa..."
She looked down at her slightly distended belly. "Does it... look bigger than when we were on the island?" she panted. She was amazed her tiny body could take all of him.
"So, we're going to the con next week?" Rin's hand slid down her spine and hooked into her...
"Eek! I haven't washed back there yet!" Sagiri punched him with her weak, pink fists. "I told you I'm not going..."
"Not going? Your body says otherwise." Rin hooked his finger slightly, making her go limp.
"Pervert! Pervert! PERVERT!"
Rin pulled her close and whispered in her ear. "If you go, I'll do that to you..."
Sagiri's neck turned bright red. After a long pause, she nodded.
"Fine... but you have to promise nobody will find out."
"I promise~"
