Could someone really feel good from being punished?
Kei was a bit skeptical.
If being punished felt good, then punishment wasn't punishment at all, but a reward.
But Rin Ito was right; the proof of a girl feeling good was very obvious. If she got it wrong, she could just apologize to Chika-san after it was over.
Kei hadn't been with Rin Ito very many times.
Rin Ito had only had one party with her, the one where Moeha tied Rin Ito up and made Kei take the initiative. Other than that, it was just Kei trying to explore where Rin Ito's limit was... and the conclusion she reached was that Rin Ito's limit was completely bottomless!
Rin Ito and Kei had only been together those two times. After she moved into Baumkuchen Studio, although Rin Ito had opened small parties here, Kei hadn't participated in them.
Although Kei had already been completely developed by Rin Ito, she hadn't had much contact with anything related to training and discipline.
"Mmh... try this one first. Doesn't it look familiar?"
"This is... a pointer?"
"Exactly."
The first tool Rin Ito let the novice trainer experience was the pointer she had seen all her life growing up.
The stiff crop with a square tip would make one feel pain when it struck, yet because the square end dispersed the impact, it wouldn't cause any real injury.
Kei had often seen teachers tap the blackboard with a pointer to get the students to focus, and she had also seen teachers strike palms with it to punish students.
However, having been a good girl with excellent grades all her life, Kei had never experienced the sensation of a pointer herself.
Holding the pointer in her hand, Kei tapped her own palm lightly with a curious expression.
Thwack!
The loud sound startled Kei herself, and the struck palm turned slightly red, though it didn't really hurt that much.
"Moeha first." Rin Ito gently embraced Kei from behind, leading her to stand in front of Moeha, pointing at the tip of Moeha's slightly swollen mounds which had just been milked dry.
"Try striking right here."
"Is it really okay?" Kei hesitated. When she tested it on herself just now, it didn't hurt much, but she had struck her palm; the sensitivity of the two crimson peaks on the chest obviously couldn't compare to a palm.
"And didn't you say just now, Ito-kun, that Chika-san is the one with a punishment fetish?"
"Chika definitely has a fetish for being punished, but since both sisters of the Fujiwara family can lactate, maybe they share the same taste for punishment."
"It's best if Moeha has this fetish; if not, just treat it as punishing her."
"This... alright, I'll give it a try."
Kei took a deep breath, and then... Spank!
"Ugh!!!"
A sharp cry escaped Moeha's lips as the tip of her breast, which hadn't yet recovered from being milked, was struck. The sharp sting made Moeha furrow her brows.
However, the force Kei used was lighter than when she hit her own palm, so instead of true pain, it felt more like a jolt of stimulating electricity.
"Look... it definitely made her feel good."
Rin Ito reached out his hand and wiped between Moeha's legs, then waved his glistening, wet fingertip in front of Kei. The feminine scent belonging to Moeha let Kei know that single strike had turned the girl on.
"I didn't expect someone to actually have this kind of fetish..." Kei muttered to herself, then raised her hand and struck the other side with slightly more force than before.
"Guh-uuu!!!"
Moeha's mouth was gagged, but a clear note of pleasure was mixed into her muffled whimpers.
It wasn't that Moeha had a masochistic fetish, but rather that the sight of the pure Kei 'corrupted' turned her on immensely; the psychological stimulation far outweighed the physical sensation.
But Moeha was definitely enjoying it.
Thwack!
Spank.
Thwack!
Kei experimentally increased her force bit by bit. Several red welts appeared across Moeha's soft, white breasts, while a stream of juices ran down her thighs.
"Next is right here." Rin Ito pointed to the delicate spot beneath Moeha's lower abdomen... As a girl herself, Kei knew exactly how sensitive that area was; it was far more sensitive than the chest.
Would it really be okay to strike her there?
"Don't worry, it won't break Moeha."
"Mmmph! Mmmph!!!" Although Moeha was gagged, her neck could still move freely, and she nodded frantically, signaling Kei that she could continue.
Although Moeha anticipated that it would indeed hurt quite a bit, as long as she could witness the sight of Kei becoming corrupted, the pain was absolutely worth it.
Having received Moeha's consent, Kei took a deep breath.
Thwack!
"Ohohohohoho!!!!"
The exact moment it struck, Moeha's body convulsed violently as if she had turned into a literal fountain, squirting a torrent of juices and fluid straight out.
Kei, who had never experienced such hardcore play, was visibly startled, whereas Kaguya and Hayasaka, with their vast party experience, were entirely unfazed.
"See? Moeha clearly felt amazing. Next up is her older sister, Chika."
Compared to Moeha, Chika—who possessed a genuine masochistic streak—stared at Kei with pure anticipation. With her previous experience, Kei was much bolder this time.
With every crack of the pointer against her nipples, streams of breast milk sprayed outwards alongside the sound.
Moeha's breast milk had been milked dry before she came down, but Chika had only just returned, and her swollen chest was packed full of milk!
Kei continuously struck Chika's body with the pointer, sweet milk squirting out with every single lash.
Chika, who had a real masochistic fetish, was even more extreme than Moeha, various bodily fluids spraying everywhere.
"Guh-eee!!!!"
Chika's body went entirely limp and sagged downwards. If her limbs hadn't been cuffed, she would have collapsed onto the floor.
Meanwhile, Kei was also panting heavily, her cheeks flushed with an unnatural crimson glow.
"How was it?" Rin Ito asked with a smile. "Felt pretty good, right?"
"Uh... it was alright, I guess."
Kei guiltily looked away. Although she didn't enjoy punishing others, she had indeed fully vented her irritation at being repeatedly interrupted earlier.
Though Kei didn't like striking people with a pointer, a win-win situation where she got to vent while they felt pleasure was something she could handle once in a while.
"Let's let them go now."
"Wait a moment." Kaguya stopped Kei, her crimson eyes gleaming with a dangerous light. "Since they have a fetish for being punished, how about letting Hayasaka and me discipline them instead?"
"Mmmph! Mmmph!!!!"
Hearing Kaguya's voice, the Fujiwara sisters struggled frantically... Even though Chika had a genuine masochistic streak, she was only a light masochist. The gentle striking force used by Kei was just right, but Kaguya...
Looking at Kaguya's terrifying expression, it wasn't hard for Chika to imagine just how much force she would use.
Although Kaguya and Chika were best friends, the longer they spent together, the more hidden resentment accumulated... especially toward Chika's massive breasts!!!
Both Kaguya and Hayasaka were flat-chested, and they harbored a deep-seated grievance toward Chika, who constantly puffed out her chest as if showing off her massive tits.
Raising her chin, Kaguya looked with total mockery at the frantically struggling Chika.
"Look, Kei, see how excited Chika gets the moment she hears I'm going to punish her."
Chika: "???"
