"Mashiro, things over there... seem very intense."
Next door.
Mashiro and Nanami's room was directly across from Kaede's. Their rooms were separated by only one window. Although the curtains were drawn, they could still see the overlapping silhouettes of the three people and hear Kaede and Suzu's seductive moans.
"It certainly is intense." Mashiro didn't stop sketching, looking through the curtains at the three figures almost piled on top of each other, imagining their positions and drawing them on paper.
Mashiro could maintain her composure, but Nanami didn't have Mashiro's self-control. Listening to the sounds coming through the window, Nanami felt a tickle of longing, and at the same time, a trace of almost imperceptible bitterness flashed through her heart. Although Nanami understood that her relationship with him was, at best, a 'fuck-buddy' arrangement, and Kaede was his girlfriend, listening to this still made her a little jealous... She truly didn't understand why Kaede had such a strange fetish.
"Should we... should we go sleep in the living room tonight?"
"Can't you handle it, Nanami?" Mashiro turned her face and glanced at Nanami. Her clear eyes seemed to pierce Nanami's thoughts. Mashiro paused, then took a reference material from her drawer and handed it to Nanami.
"...I don't want that! I have school tomorrow! I can't stay up late! Shower! Mashiro, go take a shower right now!"
"Such a hassle..." Although she said that, Mashiro still got up, casually stripping off her clothes and tossing them aside. Nanami immediately grabbed a set of pajamas and a bath towel and hurried after her, like a mother caring for her young daughter.
After a while, the physically and mentally exhausted Nanami returned to the room, and then... Overwhelmed by curiosity, Nanami cautiously climbed onto the windowsill and gently lifted a corner of Kaede's curtain...
This... this looks quite intense.
In Nanami's view, Suzu's face was buried in the chest of Kaede, who was tied to the chair, lightly biting the soft flesh, while Rin Ito was behind Suzu, grabbing her hands and thrusting deeply. Their tightly pressed chests rose and fell with their breaths, squeezing together. They could practically feel the echo of each other's heartbeats as they climaxed.
After a while, Suzu stood up, supported by Kaede's shoulder. The mixture of their bodily fluids dripped down Suzu's thigh... No, it would be more accurate to say it was a mixture of three. Kaede had also sprayed quite a bit onto Suzu's stomach, and now that Suzu stood up, it slid down with the rest.
Rin Ito gently wiped Suzu's sticky abdomen. The slick fluid stretched into a short silver thread on Rin Ito's fingertip, all while he pretended to be completely unaware of the Empathy Potion.
In reality, the System Daughter reported to Rin Ito every time Kaede climaxed. Due to the sensitivity buff, even though she received the same stimulation as Suzu, Kaede had climaxed many more times than Suzu, and... not only was she synchronized with Suzu's pleasure, but Suzu, to ensure Kaede didn't feel left out, was also gently nibbling and licking the soft flesh on Kaede's chest and teasing her sensitive spots with her fingertips. But this made things worse for Kaede. The two types of pleasure from Rin Ito and Suzu overlapped, combined with her existing sensitivity buff... Tsk, tsk, tsk.
Although Rin Ito knew the truth, he couldn't resist teasing her. "You climaxed so many times just watching me with Suzu?"
"Ugh..." Kaede had nothing to say. At this point, pretending the fluid was Suzu's sweat wouldn't work. "Fine, fine, fine, I'm a pervert who climaxed multiple times just watching her boyfriend and sister go at it in front of her, and sprayed all over her sister's stomach. Is that what you want?"
Teary eyes averted, refusing to meet Rin Ito's gaze. Rin Ito squatted down and untied the thigh-highs binding Kaede's calves to the chair legs. Suzu went behind Kaede and unlocked her handcuffs.
Rin Ito and Suzu exchanged glances. Suzu had long wanted Kaede to tell Rin Ito that she was still a virgin, and Rin Ito also wanted to expose the secret. But with Kaede's tsundere personality, she didn't want Rin Ito to think she had used Suzu to substitute for her during their "sweet first time."
"Yah~" Rin Ito picked up Kaede from the chair and threw her onto the bed... then immediately turned and embraced Suzu, pushing her down and pinning her on top of Kaede. The last time he caught them, Kaede still hadn't told Rin Ito she was a virgin... Rin Ito wanted to see how long Kaede could hold out. Before, it was only through the camera system. Now it was happening right in front of her... Is she a Ninja Turtle? Rin Ito didn't believe she could keep enduring this!
"So... so deep... you're hitting... ugh... hitting all the way inside!!!" Pinning Kaede down, Suzu continuously whispered explicit things into Kaede's ear while simultaneously gripping Kaede's wrists with both hands and forcing Kaede's legs apart with her knees, preventing her from rubbing her thighs together.
Rin Ito, meanwhile, thrust deep into Suzu every time, making her gasps and moans even more alluring.
"Ugh..." Kaede, subdued by Suzu, squirmed her body. Although the synchronized pleasure from Suzu could also make her climax, the more she climaxed, the emptier she felt. It was like a man who had been castrated one day: he could feel something, but in reality, he was empty. Suzu had been helping her with her fingers before, but now there was nothing.
Feeling the heat that Suzu felt, the fullness that Suzu felt, and the repeated penetration Suzu felt, Kaede's heart grew more and more anxious, despite climaxing repeatedly onto Suzu's leg.
"Mnh~~~" As Suzu reached her peak again, Kaede's sense of emptiness reached its limit.
"I... I want some too... Give... give it to me..." Kaede turned her face away, her voice fragmented.
Suzu glanced at Rin Ito, and their eyes met. They shared a knowing understanding. That's the same look we had when we used to tease and bully Kaede as kids!
The two instantly reached a consensus.
"Hmm? Give you what?" Rin Ito pretended to look confused, suppressing a laugh. "It's too quiet; I can't hear you."
Kaede dared not meet Rin Ito's gaze, but her voice was louder than before. "Treat... treat me the same way you treat Suzu."
"Treat you the same way I treat Suzu, huh..." Rin Ito smiled and nodded, gently patting Suzu's butt, handing the baton for teasing Kaede over to Suzu.
Suzu, pinning Kaede down, supported herself on her hands and stared at her older sister with moist eyes. Although Suzu didn't know about the sensory synchronization, she could tell Kaede couldn't take it anymore. But seeing Kaede's cute expression, she couldn't resist severely teasing her.
"No... this is today's punishment."
"Don't hold a grudge at a time like this!" Kaede was on the verge of tears... I wish I hadn't insisted on saving face in front of Eiri and the others. Now look at me...
"You have to wait until the punishment is over."
"No!!! Please don't do this!!!"
Ignoring Kaede's pleas, Suzu continued to hold down Kaede's wrists and looked at Rin Ito. Rin Ito, understanding, continued to thrust hard into Suzu. The sounds of flesh colliding and fluids splashing, the moans of her sister right next to her ear, and the empty climax that felt rootless—everything made Kaede desperate.
"Eeek!!!" Kaede didn't know how long it lasted before the exhausted Suzu collapsed onto Kaede's body.
"Now... now, can we stop?" Suzu propped herself up and looked at Kaede's tear-filled eyes. "Are you very upset?"
"Mhm..." Kaede sniffled. "He's my boyfriend..."
"It's okay." Suzu leaned down and kissed the tears near Kaede's eyes, then looked straight into Kaede's eyes with a serious expression. "We're sisters... I won't take him away. I promise."
"Suzu..." Kaede looked at her sister with a complicated expression.
However, her moment of gratitude didn't last long. A moment later, Suzu straightened up and shifted her knees, clamping Kaede's face with her thighs. As Suzu's muscles contracted, a white, sticky fluid dripped onto Kaede's lips. The mixture of male and female fluids made Kaede's mind go blank.
"Suzu!? W-W-W-What are you doing!?"
"Sharing half with you." Suzu said faintly, then changed her position.
"Sharing half with me? Mnh....!???" Before Kaede could finish, Suzu, having changed position, sat on Kaede's face, while simultaneously leaning down and burying her face between Kaede's legs, cleaning up the mess between Kaede's thighs without any sign of disgust. The warm, moist, sticky, peculiar sensation of Suzu's tongue sent a shiver down Kaede's spine... This was the first time she had been licked like this.
Seeing Suzu so dedicated, Kaede also stuck out her tongue and drew the fluid, mixed with the scents of her sister and her boyfriend, into her mouth.
"Mnh!?" Kaede seemed to have forgotten one thing: she was still under the effects of the Empathy Potion. While she was cleaning up for Suzu, she could also feel the sensation of her own tongue. It was like being licked by two people at once... a strange feeling.
Suzu also felt a unique sensation... the feeling from her sister was completely different from the feeling from Rin Ito. Rin Ito's tongue was more aggressive, while Kaede's was gentler.
However, Suzu didn't lick for long before lifting her head and yielding the position to Rin Ito.
"Mnh, mnh, mnh!!!" The moment Rin Ito touched her, Kaede quickly propped herself up on Suzu's butt to create space to speak. After licking the corner of her mouth clean, Kaede quickly said, "Wait, wait, wait, wait, wait a minute!!!!"
"Didn't Kaede say she really wanted it?" Suzu looked down at Kaede confusedly. Why the sudden stop?
"I do want it, but... First, put on a condom, or what if I get pregnant?"
"???" Suzu was even more confused, a hint of bewilderment in her eyes. "Didn't you buy that birth control pill with no side effects?" When I was filled up like a cream puff and even the 'baby's room' was filled, didn't you give me birth control pills? So why a condom when it's your turn?
"No, I..." Kaede was at a loss for words... It's because that cursed System's anti-cuckold item can only be redeemed for other cuckolding girls! They can all be filled up freely, but I, the heroine, have to use a condom with my boyfriend! What kind of world is this!
But she couldn't tell them about the System, and she also had to tell them she was still a virgin... Whatever, since it's come to this, I might as well tell them everything.
After a long internal struggle, Kaede finally spoke slowly, her voice trembling. Kaede grabbed Suzu's thighs and made her sit directly on her forehead, blocking her eyes and only leaving her nose and mouth exposed. An ostrich burying its head in the sand? You're burying your face in your sister's butt, huh?
"I... I'm actually still a virgin. I was very happy when I heard you wanted to have our first time together, but I have a cuckold fetish, so... ugh... so... I covered my eyes and had Suzu substitute for me, and I narrated for Suzu on the side!!!!"
Although he already knew, Rin Ito couldn't help but want to laugh, seeing Kaede self-destruct with her face buried in Suzu's butt... Fortunately, Kaede had covered her eyes. Rin Ito only had to cover his mouth to keep from laughing out loud.
"So... wearing a condom makes me feel better because other women can be filled up freely, but I can't!!!!"
Rin Ito's stomach was cramping. After taking a few deep breaths, he managed to stabilize his voice temporarily. "I-Is that so... Nanami, help me grab a few condoms from the second drawer of Mashiro's desk." Rin Ito said toward the window. "You were peeking, weren't you?"
Nanami lifted the curtain and gave an embarrassed laugh. "Sorry!!! I didn't mean to!!!! I-I-I'll go get them now!!!"
"Eh? Nanami!? Peeking!?" Kaede's body froze... Nanami peeking means she heard everything just now!???
It's over. It would have been fine if only the person closest to her knew, but now... Nanami and probably Mashiro, too, had heard everything. Kaede's only thought now was to squeeze through the gap in front of her, crawl into Suzu's baby's room, and start her life over!
A moment later, Nanami's hand, holding a box of condoms, reached through the window curtain. Rin Ito took the condoms. "If you two want to watch, Nanami, you can just come over."
"No, no, no, no need!!!!" Nanami pressed her hand over Mashiro's mouth. If they went over now, they would definitely become part of their play! They would have to do many embarrassing things! For example... sitting on Kaede's face after being filled up? Although she hadn't sat on Mashiro's face, Mashiro had licked her before. But Mashiro was Mashiro, and Kaede was Kaede. Kaede was a good friend, and Mashiro was like a daughter to her, and she was already used to playing with Mashiro... she was clearly more shy in front of Kaede.
Rin Ito didn't mind if Nanami and Mashiro didn't come. Today's main course was Kaede. Suzu took the condom from Rin Ito's hand, then shifted her butt slightly. "Hurry up and continue, or I won't put it on him."
"..." Kaede was speechless... Who asked her to be my sister?
Holding Suzu's thighs and adjusting her position, Kaede continued to clean up her boyfriend's fluids from her sister's body. Although Kaede had never tried this before, the Empathy Potion allowed Kaede to precisely understand Suzu's feelings, knowing whether Suzu was comfortable or in pain.
"Kaede... you're so... amazing?... " Suzu clamped Kaede's face tightly with her thighs, and her ten toes curled up tightly to endure the pleasure.
Feeling Suzu's sensation, and knowing Suzu was struggling, Kaede's playful side emerged. She had always been teased by her sister before, but now...
"Kaede... slow down?... !!!!" Suzu quickly used her trembling hands to put the condom on Rin Ito. If this continued, she would really expose a shameful side in front of Kaede!!!!
"We're starting now," Rin Ito said, patting Kaede's thigh to warn her.
"Mnh... ugh..." Although Kaede couldn't see, she could feel Rin Ito was ready, and Suzu, bracing her weakened body, wrapped her arms around Rin Ito's shoulder and offered her lips to his.
The moment he stabilized Suzu, Rin Ito thrust his hips slightly. Kaede's body was already perfectly ready, so lubricated that it could not be any more so. There was barely any resistance, only a slight hesitation before he fully entered Kaede.
"Ugh!!!" Trying to stifle a cry of pain, Kaede instinctively sucked on the full nipple in front of her. The stimulated Suzu tightly kissed Rin Ito's lips.
The three formed an isosceles triangle. Kaede was on the bottom, sandwiched between Rin Ito and Suzu, forming the base of the isosceles triangle. Suzu, sitting on Kaede's face and kissing Rin Ito, formed the two sides of the isosceles triangle with Rin Ito.
As is well known, the triangle is the most stable shape.
