After rewarding Karen, Rin Ito watched as she began to clean him up while he turned his focus back to Mutsumi.
To maintain their symbolic performance, Mutsumi and Mortis resumed their rhythmic spanking of Sakiko's rear.
"I didn't expect Mutsumi to start slacking. Didn't I tell you how I wanted Miss Toyokawa's ass to look? If you won't do it, don't blame me when I hit 'send' on those photos."
"No! Stop!"
Rin shot Sakiko a look. She instinctively tried to open her mouth to play along, but the collar she was biting slid out and clattered onto the floor.
"Dropping your collar? Disobedient kittens need to be disciplined properly... Roll over and lie on your back!" Rin barked.
Even though Sakiko was in on the plan, the authority in his voice made her flinch. She submissively rolled over and squeezed her eyes shut.
When she was on all fours, Rin's view had been limited.
But now... everything was on display. Her petite, firm breasts—perfectly sized to be cupped by a hand—and her wet, glistening junction were laid bare before him.
Mutsumi was slightly thinner, likely due to her internal stress. Sakiko, by comparison, looked a bit more succulent and soft.
"Is this how a kitten lies down? Karen, teach her the proper form."
"Raise your arms and legs. Curl your wrists like paws... your legs, too."
Karen physically adjusted Sakiko's limbs. Rin and Mortis watched as Sakiko lay there, four legs in the air, curled up like a helpless newborn kitten. They both struggled to keep a straight face.
No, I can't laugh. It'll ruin the mood!
"Ahem... Cough." Rin suppressed his laughter with a fake cough.
Sakiko felt ten times more humiliated than she had during the spanking. This "kitten" pose offered zero protection; she couldn't hide her expression or her body.
Her amber eyes were swimming with tears of shame, and she bit down on the retrieved collar to endure the embarrassment.
But she didn't have much time for shame. With her legs up, her most delicate area was wide open. It was time to make her surrender everything.
As the Toyokawa heiress, she had spent her life in all-girls schools. Her experience with pleasure was limited to clamping her legs together or squeezing a pillow.
To Rin, a girl who had never explored her own body was a literal gold mine.
He had promised not to take her virginity today, but there were countless other ways to "develop" a girl.
His left fingertips traced the valley between her breasts before sliding down to her stomach. His right hand reached around her raised thigh to firmly pinch her most sensitive nub.
His left hand applied heavy pressure, sinking into her soft abdomen, while his right used the slightly rough pads of his fingers to grind against her.
For a girl like Sakiko, this was an overload. Her entire body went rigid the moment he started.
"I told Mutsumi to spank you until you squirted. Since she failed and you don't want those photos leaked..."
"I'll just have to double the penalty by turning you into a literal 'pump' manually."
A pump?
Before Sakiko could process the meaning, Rin's fingers—previously massaging gently—suddenly applied a violent, focused force.
"GUH-WOOO!!!!"
A surge of intense stimulation, the likes of which she had never imagined, raced from her core up her spine and exploded in her brain.
Her slender waist arched by reflex, but that only pushed her deeper into his hand. She tried to squirm away, but Karen's hands pinned her shoulders to the bed.
"EEEEE-IIIIII!!!!"
With no escape, Sakiko could only let the tidal waves of pleasure ravage her mind. Her brain felt like it was being scrambled into a white void.
The band, her father, her poverty—every worry was incinerated by the raw, physical ecstasy.
And then...
She blacked out.
As her body gave a final, violent convulsion and a flood of warm, golden heat erupted from her, Sakiko's consciousness hit its limit. Her limbs went limp and fell like a kite with its string cut.
A strange ceiling...
When Sakiko opened her eyes again, she found herself staring at an unfamiliar ceiling. Her neck felt heavy, constricted by something.
She sat up, her body aching, and looked into the full-length mirror near the wall.
The blue-haired girl sat naked on the disheveled bed. The only thing she was wearing was a black collar adorned with a single crystal.
Unlike the deep red "pet" collar from earlier, this one looked less like a mark of slavery and more like a high-end accessory.
Is it over?
As the fog cleared, she felt a heavy, dull ache in her muscles.
Thud.
Sakiko fell back onto the pillows, breathing deeply with her eyes closed. She curled into a ball, the memories of her blackout returning in flashes.
Forget everything... In that peak moment, it really felt like Karen was right. It was as if every worry in her life had been flushed out of her body along with that flood of fluid.
Wait... before I passed out, did I... did I actually piss myself?
He had been pressing and massaging her stomach so hard... she had turned into a literal fountain.
She stood up and looked around. Her uniform was gone. Walking on slightly shaky, aching legs, she pushed open the bedroom door and entered the living room.
Karen and Mutsumi were gone. Only Rin Ito sat on the sofa, scrolling through his phone.
"Awake?" Rin looked up with a playful grin at the naked girl in the collar. "How are you feeling?"
"Wh... Where are my clothes?"
Sakiko covered her chest with one hand and her crotch with the other. Even though he had already seen every inch of her, she couldn't face him with stoic nudity.
Rin pointed to a pile of neatly folded clothes. Sakiko snatched them and ran back into the bedroom to dress.
Wait... why are my panties missing!?
No underwear, but at least she had her shirt and skirt.
When she returned to the living room, her face was still red, but she tried her best to look stern.
"Mutsumi... how is Mutsumi doing?"
Sakiko cared more about her friend's mental state than the fact that she had just been turned into a "pump."
"Mutsumi... well, she's better. But she says it isn't enough."
Rin opened his chat with Mutsumi and handed the phone to Sakiko. The exchange was blunt.
Rin Ito: [Well? Do we keep going?]
Mutsumi: [Keep going.]
Mutsumi: [Eat Saki.]
On this, Mutsumi and Mortis were in total agreement. Mutsumi wanted Sakiko to be free of her stress; Mortis wanted cold revenge. Simply making her leak wasn't enough for them.
She had to be "devoured" completely.
"The next step depends on you."
Rin tossed the ball into Sakiko's court. Hehe... I want to hear those words come out of your own mouth, Saki-chan!
"No rush. Mutsumi can wait," Rin smiled. "Before you decide on being 'eaten', think about the band. Are you joining Mutsumi?"
Sakiko didn't hesitate. The "breeding" might require thought, but the music didn't.
"I'll join."
