Even though it was early spring and the night air held a biting chill, under the warm amber glow of the lights, Tomoko felt as though her entire body were on fire. She didn't have a single stitch of clothing left on her, and her curvaceous, pale body was flushed with patches of deep pink.
The contrast of alabaster skin and rosy heat made Tomoko, her hair tied back in a high ponytail, look even more intoxicating. Unfortunately, there was no one to admire this exquisite sight—yet.
Watching the two silhouettes entwined in the bathroom, Tomoko instinctively moved her hands, placing one over her breast and the other over her lap. Unlike Serena, she was quiet by nature and had spent most of her life barely considering the affairs of men and women. Aside from the diagrams she'd seen in health class, she was a complete novice.
"That kind of thing... really seems to feel incredible..." Tomoko whispered to herself. As the rhythmic, muffled moans drifted from the bathroom, her slender fingers began to move in sync with her sister's cries, sliding and stroking with an instinct she didn't know she possessed.
Inside the bathroom, Yuu had no idea there was another beauty waiting in the wings. His attention was entirely focused on Serena, the "pure-yet-filthy" little bitch who couldn't get enough. After a few rounds in the classic missionary position, Yuu decided it wasn't stimulating enough. He scooped up the limp, sweaty girl and pressed her firmly against the smooth white tiles of the wall.
Serena's back was slick with soap and sweat, and the high-quality tiles were covered in condensation; there was zero friction. To keep her from sliding down, Yuu had to lunge forward, pinning her between the wall and his own body. His "anchor"—Little Yuu—was buried almost entirely within her tender passage.
Serena was pinned high against the shower wall, standing on one leg while the other—pale, slender, and showing hints of athletic tone—was hooked over Yuu's arm. Yuu showed no mercy, his movements wide and powerful, his large hands gripping her narrow waist to brace himself for each heavy thrust of his hips.
The girl's fair skin turned a deep peach blossom pink under his assault. Though Serena craved the pleasure, her stamina was reaching its limit. She couldn't handle the relentless pounding of the dragon. Every time he bottomed out against her soft womb, the sensation of overwhelming fullness and sparks of electricity was almost too much to bear. She bit her lip, gasping weakly, her arms wrapped tightly around Yuu's neck as if terrified of falling.
"Ah... nh... mmm..."
After a series of short, sharp gasps, Serena's mind went blank. When she finally came to, she couldn't take it anymore and began to beg for mercy.
"Hoshimiya-sensei... I'm sorry... I was wrong. I shouldn't have broken it myself... I should have saved it for you..." As she apologized, she caught a glimpse of a familiar silhouette standing by the frosted glass door. Relieved, her mind whirred, and she continued, "Hoshimiya-sensei, please... spare me... I really can't go on..."
"No doesn't mean no tonight. I'm going to punish my naughty, lustful student properly!" Yuu was partly 'retaliating' for her breaking her own seal, but mostly he was just reveling in the ecstasy of ravaging a billionaire heiress.
"Wooo... I really know I was wrong..." Serena leaned into his ear, panting heavily. "How about this? To make it up to you, I'll let Big Sis Tomoko give her 'first time' to you instead~ My seal wasn't saved for you, but hers is still intact. You can use her as a substitute... okay?"
"A sister paying a sister's debt?" Yuu thought she was joking, but he couldn't help but picture Tomoko—the elegant, squinty-eyed beauty with the long hair. The thought of taking that gentle, submissive Yamato Nadeshiko and turning her into a shivering mess like Serena made him surge with a new wave of excitement. He delivered a few more heavy thrusts before an even more scandalous idea struck him.
"If we're talking about debts, one sister isn't enough. We need interest!" Yuu nipped at Serena's rounded earlobe, whispering hungrily, "If you can get Auntie Ayako to join in, I'll let you off the hook tonight."
Hearing her mother's name, Serena's body shuddered. She hadn't expected Yuu to be even bolder than her. After the initial shock, a wave of intense pleasure hit her. True to her deviant nature, she didn't find the idea wrong—she found it incredibly thrilling. Her slender body convulsed as she imagined the three of them—mother and daughters—serving Yuu together, and the fantasy alone sent her over the edge one more time.
After this climax, she was completely spent. She gave Yuu a flirtatious, lingering look and said lazily, "Hoshimiya-sensei, you're so greedy... you won't even spare my mother."
"What? Are you jealous?" Yuu slowed his pace. The night was still young, and he didn't want to spend it holding an unconscious Serena; that would be boring.
"Not at all," Serena said candidly. "As long as you have the skill to do it, I'm perfectly fine with it. I'm actually quite curious to see what my strict, serious mother would look like in bed."
Yuu couldn't agree more. He wanted to see the "gap moe" of the powerful Ayako Suzuki in bed, and he definitely wanted to see how the serene Tomoko would perform. But for now, those were just fantasies; the only one he had was Serena.
Just as Yuu was about to use Serena to work off the heat of his fantasies, she sensed another grueling round was coming and quickly said, "Sensei, I'm really done. Let Big Sis Tomoko pay the debt for me."
"Hmm?" Yuu paused, looking at her with confusion. "You're serious?"
Serena giggled. "I'm serious. Your charm is too much, Sensei—Big Sis Tomoko fell for you at first sight."
At that moment, Tomoko—who had been eavesdropping outside—knew it was time. She moved her bare feet across the floor and slowly slid open the bathroom door.
Slide—
Yuu instinctively turned his head. His eyes were met with Tomoko's mature, flawlessly developed body. She was luminous, alabaster skin shimmering in the light, with curves in all the right places. Heavy breasts, a tiny waist, rounded hips, and long legs. Seeing the beauty he had just met that afternoon standing stark naked before him made Yuu daze for a split second.
Seeing Serena and Yuu physically joined together gave Tomoko a massive shock. It was one thing to fantasize about silhouettes; seeing the "high-definition, uncensored 3D" reality up close was an indescribable impact. Every word she had prepared to say vanished. She could only stare blankly at Yuu's powerful, well-built physique.
So this is what a man looks like...
Tomoko's gaze drifted to the junction where Yuu and Serena were connected, wanting to witness the truth of the union of Yin and Yang. Yuu didn't disappoint her. He decisively pulled the roaring dragon out of Serena's body. The beast, glistening with moisture, swayed as it moved toward the new enemy.
"Ah!"
Before she knew it, Yuu was in front of her. The massive dragon pressed against her cute navel. The long-haired beauty finally snapped out of her trance and let out a small cry. She cried out, but she didn't move away. Instead, her eyes—finally opened wide—were filled with curiosity and longing.
When the "squinty-eyed" beauty opened her eyes, she was unexpectedly stunning; beneath her gentle exterior lay a soul full of life. If Serena's beauty was "sealed" by her headband, Tomoko's was sealed by her closed eyes. Both sisters were top-tier beauties, but their quirks made them surprisingly overlooked in daily life.
Yuu didn't understand why Tomoko was offering herself so readily, but he wasn't about to waste time investigating. He'd just take Serena's word for it: love at first sight!
Tomoko, who was busy observing "Little Yuu," suddenly felt herself pulled into a powerful embrace. A tingling sensation she had never felt before traveled through her delicate skin, like an electric current surging from her toes to her brain. Before she could process the feeling of skin-on-skin contact, her lips were invaded.
Yuu captured Tomoko's cherry-blossom lips, prying past her pearly teeth to catch her shy, flickering tongue in a deep, hungry swirl.
