Edging.
Sagiri was intimately familiar with this. She had experienced it before... back then, Rin had even asked Eromanga-sensei to help watch over her. A whole day of that had nearly driven Sagiri insane.
That was true edging. What was happening now was just a bit of light foreplay—hardly worthy of the name.
Gulp...
Sajuna stood nearby, holding her breath and staring. Her mind couldn't help but picture Rin and Marin tangled together.
It was like a self-fulfilling prophecy. Kaede's sensory link made Sajuna believe her imagination was so vivid it was malfunctioning. Just by watching, she could feel everything. Because she thought she was overly sensitive, she reflexively imagined things—to the point where even when Rin wasn't touching Marin, she felt his hands on her own body.
In front of her, Rin yanked the chain around Marin's neck, causing her to stumble. He ruthlessly pulled down the collar of her outfit.
Her youthful, pale breasts bounced like jelly. The soft white flesh, partially veiled by thin erotic lingerie, traced elegant curves in the air, drawing envious stares from the other girls.
Thinking about it... if you added Sagiri, Ai, Kaguya, and Sajuna together, were they even as big as Marin?
According to Rin's manual measurements... probably not.
Sagiri and Sajuna were practically flat boards; Kaguya and Ai were below average. None could compete with Marin's sheer volume.
"Hmph... acting all cold and stiff at school, yet wearing such slutty underwear... take off your panties."
"..."
With a stoic face, Marin bent over and pulled off the thin, purple lace panties she had just put on. They were already soaked and sticky.
"Just as I thought. Already this wet before we've even started. Such a degenerate little bitch..." Rin reached under Marin's skirt. Though he couldn't see, his hand followed the heat and moisture, accurately pinching Marin's most sensitive spot.
"Nngh..." No matter how hard Marin tried to maintain her "Ice Queen" facade, she couldn't stop a low whimper from leaking out. However, Rin didn't pleasue her further or send her over the edge. He teased her with a light, intermittent touch.
After a while, Rin wiped his wet fingers across the tip of Marin's nose, forcing her to smell her own musk. Then, at his command, Marin lifted her skirt and bit the hem in her mouth.
Rin toyed with her, smirking. "Do you want it? Beg me if you do."
"..."
Marin soon collapsed into Rin's arms. She was enduring it well, only letting out soft hums without begging for mercy.
Rin said nothing, focusing entirely on the edging training. He was wearing an earpiece; System-Daughter could clearly relay Marin's progress to him, telling him exactly when to stop.
Marin wasn't faking her resistance either. Some things feel much better the longer you hold them in. Every time she neared her limit, Rin stopped. Even without the system's help, he could feel the rapid, forceful contractions of her pussy walls against his fingertips.
And then... Stop!
Over and over. Each time, Rin toyed with her until she was on the brink. After three cycles...
"Please..."
The voice begging for mercy finally reached Rin's ears.
But it wasn't Marin. It was Sajuna.
"Please... just give it to her already."
Rin looked over. At some point, Sajuna had approached them, her legs clamped tightly together.
Kaede had now linked Sajuna's senses to Marin's. Since Rin wasn't being overly aggressive, Kaede had set the link at 50%. Rin edging Marin was effectively edging Sajuna at the same time.
The phantom, itchy sensation from her crotch made Sajuna's knees weak. Fortunately, it wasn't strong enough to make her collapse entirely. She stumbled closer to them. I still feel this way because I haven't watched enough! I haven't built up an immunity! Once I see it all, I won't feel anything next time!
So... it definitely wasn't because she wanted it!
But...
"I can't do that. Marin hasn't begged yet."
Rin looked at Sajuna with wicked amusement. No one else knew her secret, but he was fully aware. Even through the black fabric of her butler pants, he could see a faint, darkening wet spot.
"W-why not? She... she looks so pitiful. Just... just give it to her."
"I'm fine," Marin added, panting. She was also feeling mischievous. She didn't know the specifics of Sajuna's condition, but she could tell the girl was in a state of high arousal.
"Putting aside whether Marin begged or not... Sajuna, in what capacity are you saying this? This is a Baumkuchen gathering, after all."
"Besides... isn't it actually you who wants it, Sajuna?"
Sajuna was right next to them. Within reach.
Rin reached out and placed his hand directly between Sajuna's thighs. The moment he touched her, his other hand pinched Marin's clit.
"Eeeeeiii!!!!"
Rin's edging had already pushed Marin to the breaking point. Combined with Sajuna's first time being touched by a man after a lifetime in an all-girls school...
Sajuna's legs turned to jelly instantly. She threw her arms around Rin's arm, pressing her entire weight into his palm.
"Mmmgh—!!!!!"
She couldn't escape even if she wanted to; she couldn't even stand up. Her fingers dug into Rin's arm, leaving marks, but she couldn't stop the flood gushing from her.
Haa... haa...
As her breathing slowed, Rin whispered in her ear.
"You really wanted to see it, didn't you? To see Marin lose her purity while in cosplay... Even though this is a circle meeting, as the President, I can satisfy a newcomer's little whim."
The release wasn't as intense as the one in the parking lot, but the edging had left Sajuna in a daze. Rin's hand never left Marin, and the constant stimulation kept Sajuna's desires simmering.
Sajuna's lips trembled for a long time. "I... I'll join."
Haa...
"So... please..."
Haa...
"Give it to her... Eeeeiii!!!!"
