"...Kaede?"
Having her most private weakness handled by someone else for the first time made Ichika freeze. She had known she was wet, but girls weren't like boys. A boy's excitement was obvious through his pants; a girl could hide it unless she was completely overflowing.
Ichika expected Kaede to notice—they were both girls, after all—but she never expected her to actually reach in and touch.
"Are you excited because of Nanami's voice? Or are you imagining your sisters with the man you love?"
"Ah... hahaha..." Ichika could only offer an awkward, panicked laugh. Kaede pulled her hand back and used a tissue to wipe her fingers.
Phew... Ichika let out a long breath. If Kaede had kept going, she didn't know what she would have done. Though... the feeling of those slightly rough fingertips on her clit had been incredibly good.
"Don't be so embarrassed," Kaede said brightly, breaking the tension. "Rinon and I grew up with him. He was like a big brother... then, after the 'accident' with our family, it became what I told you."
"I... I understand."
"If you weren't here, I'd be over there too. But since I have a guest, I have to stay. Though, listening from next door has its own charm."
If Rinon were there, she would have called bullshit. 'Charm'? You mean your cuck fetish?
"Eh? Don't mind me! Go if you want to! I'll be fine here alone!" Ichika said quickly. Being in this room while they did that next door was awkward enough; it would be better if Kaede just left.
A sly glint appeared in Kaede's eyes. "Am I in the way of your 'private time'? If that's the case, I guess I'll head over."
"I didn't say that!"
Ichika did plan on touching herself, but she couldn't admit that to Kaede! Usually, she was the mature one, but tonight, Kaede was playing her like a fiddle.
Fine, whatever! It's your boyfriend getting laid next door!
"I see..." Kaede teased. "By the way, Ichika, what position do you like? Oh wait, you've never had a boyfriend, right?"
"Yeah. Plenty of guys confessed to me, but... they couldn't even tell me apart from my sisters. Some guy even confessed to me using Itsuki's name." Ichika laughed at the memory. "Hey, can he tell you two apart?"
"Even if he's blindfolded, he can tell us apart just by the feeling inside our bodies."
"Really?"
The idea of being identified by the texture of her vagina was a total "knowledge blind spot" for Ichika. She'd only ever felt her own. Can you really tell the difference like that?
"Of course... You really should get a boyfriend soon. How are you going to film kiss scenes or bed scenes otherwise?" Kaede said casually.
"I'm not filming porn! Why would there be scenes like that? Normal movies use camera angles for kisses, and those are for leads anyway. I'm just an extra."
"You never know... anyway, I need to use the bathroom."
"Hehe... no you don't!" Ichika grabbed Kaede's hand, feeling bold. "You're going to the bathroom to touch yourself, aren't you? Stay here."
Finally, Ichika thought, a chance to tease her back.
"Tch... you caught me." Kaede sat back on the bed, looking pouting. Ichika pressed her advantage. "So... how many of you do it at once? What's the position?"
This was exactly what Kaede wanted. She had been leading Ichika down this path the whole time.
"If it's just me and Rinon, I like '69'. I stay on the bottom, she's on top... that way I can use my tongue to make both of them feel good. And every time he thrusts into her, his cum splashes all over my face."
"!!!!!"
"And when they finish, Rinon just sits her sweaty ass right on my face. The smell of my two favorite people mixing together... it makes my 'baby room' so hot it throbs~"
Kaede described the threesome with vivid, graphic detail. Ichika might act mature with her sisters, but as a virgin, she was no match for a "corrupt" veteran like Kaede. Despite trying to look unfazed, Ichika's face was flaming.
As Kaede spoke, she secretly bumped the Sensory Sync from 10% to 20%.
"By the way... do you want to see what they're doing?"
"!!!!!" Ichika held her breath. "No...!!!!"
Before Ichika could refuse, Kaede had already started a video call to Rinon. After a brief buzz, Rinon's face appeared on the screen.
"Ichika says you guys are too loud. As an apology, she wants to watch."
"Sure~" Rinon flipped the camera.
The screen was suddenly filled with the three of them.
"Ichika... don't... don't look at me like this..."
Nanami was on the screen, held face-to-face by Rin. Her white, slender legs were wrapped tightly around his waist. Mashiro was behind her, using a vibrating toy on Nanami's anus. Nanami was arching her back, her face a mask of pure, shameful pleasure as she let out those seductive cries.
"!!!!!"
Ichika forgot to breathe. The kind, sensible Nanami was making the most lewd, beautiful face she had ever seen.
While Ichika was stunned, Kaede pulled her onto the bed and handed her a blanket. Kaede leaned against the wall, covering herself with the blanket. One hand held the phone; the other disappeared under the covers. She motioned for Ichika to join her.
"....?"
Ichika hesitated, but seeing the unnatural flush on Kaede's face and the rhythmic movement under the blanket, she knew exactly what was happening. Her own panties were already soaked through.
If Kaede is doing it...
Nanami, Rin... I'm so sorry for using you as 'side dishes' for my masturbation!!!!
Ichika sat next to Kaede and pulled the blanket over herself, her knees forming a little tent. With a slight wiggle, she kicked her pajama bottoms and her drenched panties down to her ankles.
The two girls shared a look of silent understanding.
"Nanami," Rin said, looking at the camera on the bedside table with a wicked grin. "Ichika is using you as a side dish right now. You better put on a good show. Ichika, what position do you want to see?"
Ichika's mouth opened and closed. Her instinct to act like a mature adult fought with her skyrocketing arousal. The power to order Nanami into a shameful pose... her heart was thundering.
She took a deep breath, trying to sound sophisticated.
"I can't pick a specific pose... but Nanami, just moaning is a bit boring. I want something more intense."
"True," Rin said. "Nanami, you've played 18+ Galgames, right? Act like one of those heroines."
"You... you guys are bullies!" Nanami wailed. She had played a few, where the heroines narrated every disgusting sensation their bodies felt. No one did that in real life!
"Time to test your acting skills. Don't worry... we'll help you."
"Eh?"
Rin reached into Mashiro's toy box and pulled out a small, oval vibrating egg on a cord. It was a basic, entry-level toy.
That's it? Nanami thought.
But then Rin pushed the egg deep inside her, right against her cervix, leaving only the cord trailing out. Then he picked her up and slammed himself back into her.
"Wait!!! Take it out... hieeee!!!!"
Now Nanami understood. The vibration was rattling her very core as he hammered into her. Mashiro followed Rin's lead, taking a double-ended toy and sandwiching Nanami between them like a human burger. Rinon, meanwhile, fixed the phone's position and pressed a high-powered wand against Nanami's lower abdomen.
"I'm... I'm going to break!!!! My womb is shaking! It feels like my insides are melting into soup! Ahhh! Master's big cock is crushing the egg! It's too much! I'm cumming! I'm cumming so hard!"
So cute! Ichika thought. Even in her depravity, Nanami was adorable.
Watching Nanami narrate her own destruction, Ichika forgot to breathe. Beside her, Kaede—whose sensitivity was dialed up to "Easy Mode"—was arching her back and shivering, lewd whimpers escaping her lips. Ichika could hear the wet, frantic sounds of Kaede's fingers under the blanket.
Ichika was under the blanket too, but she hadn't dared to start yet. Seeing Kaede go for it gave her the courage. Her movements were smaller—she wasn't used to masturbating next to a friend, and she was still a virgin—but she finally reached down.
Kaede, after a quick, intense climax, fought the urge to go again and leaned her sweaty body against Ichika. Today was about "corrupting" her.
"Think about it, Ichika," Kaede whispered. "Your 'boyfriend' is currently holding your 'best friend' while they fuck... and here you are, watching them and masturbating yourself to climax~"
