Ethan's interest in Serafall wasn't purely about her looks. Unlike Sona, who was still in a phase of rapid growth, Serafall was already one of the top powers in the Three Realms. Sirzechs was the strongest of the Four Devil Kings, with hidden power likely rivaling a Chief God or even a Dragon God. Serafall might be a step behind him, but not by much. Anyone who actually believed they were just "Satan-class" was a fool. You don't overthrow the original Devil King bloodlines and their ancient houses with just mid-tier strength.
However, Serafall would be much harder to conquer than Sona. The current Leviathan might look youthful and act a bit childish, but she was sharp as a needle. Ethan wasn't worried about her causing trouble over Sona, though. Sona would take his side, and once a "sister-con" like Serafall saw her sister had already defected to the other side, she would have no choice but to accept it.
To ensure he didn't look like a "hit-and-run" bastard, Ethan stayed at the Sitri estate until the next morning. Only after Serafall returned and spoke with Sona did he head back to the human world. As expected, Serafall saw the change in Sona instantly. Setting aside the physical glow of a girl becoming a woman, Sona's jump through several realms of power was impossible to hide. Serafall, surprisingly, said nothing, merely wearing an expression of "this is for the best."
"Sera-sister, since the President is fine, I'll be heading back," Ethan said.
"Mm, thank you for your hard work." Serafall smiled brilliantly. "Little Sona needs time to stabilize. I'll leave her peerage in your hands for the next few days."
Ethan returned to the human world with Tsubaki. Two days later, Sona returned with the power of a Mid-tier Devil King. While still below the peak-Devil King level of Rias and Akeno, it left the rest of the Student Council speechless.
Sona didn't hide the truth from her peerage. "There's no need to wonder. Ethan and I dual-cultivated. If any of you are willing, you can also..."
"President, really?" Before she could finish, a white-haired girl interrupted with excitement. It was Momo Hanakai. Among the peerage, Momo was one of the most bold and open-minded. She had clearly been waiting for this.
"But will Ethan-kun agree? What if he refuses?" asked Ruruko Nimura. She was the youngest and more timid, but also one of Sona's first servants.
Sona sighed. "Trust me. With your looks, that little pervert won't refuse."
Tsubasa Yura mused, "I usually like wilder guys, but Ethan-kun... yeah, he works."
"Haha, Tsubasa feels that way too?" Tomoe Meguri laughed. "I like younger boys, but for Ethan-kun, I can make an exception."
Basically, their individual types didn't matter when faced with Ethan. It's like a man who loves milfs—if you put a perfect "legal loli" in front of him, is he really going to say no?
Sona decided that for any future Evil Pieces she used, she would add a requirement: they must become Ethan's women. She had already learned from Rias that pieces influenced by Ethan could no longer reincarnate males anyway.
The meeting happened while Ethan was away, but he heard the details that evening. Momo Hanakai didn't waste time. After school, the slender, white-haired beauty grabbed Ethan and pulled him toward her apartment.
"Momo-chan, what's this about?"
"Ethan-kun, I want to dual-cultivate with you," she said bluntly once they were inside. "The President gave her permission."
Ethan chuckled. "Sona gave permission to you, not to me."
Momo arched an eyebrow. "Are you saying you're rejecting me?"
Ethan rubbed his chin, looking her up and down. Just as she was about to snap, he winked. "No, I agree too."
"Hmph—" She tried to look annoyed, but her eyes sparkled with relief.
"Momo, do you live alone?" Ethan asked, dropping his bag. The apartment was small but cozy, smelling of a teenage girl's perfume.
"No, Reya lives here with me," Momo said, her face flushing. "But tonight... it's just the two of us."
No matter how bold she acted, she was still a virgin. Realizing she was about to cross the threshold into adulthood made her shy. Ethan realized the girls had probably talked this over. He didn't hesitate, picking her up in a bridal carry and heading for the bathroom.
"Kyaa!" She squeaked as his hot hands gripped her thighs.
In the bathroom, Momo refused to let him wash her, but she did provide a "tit-push" cleaning service, rubbing her soapy, soft body and small hands all over him before scurrying to the bedroom to finish getting ready.
Ten minutes later, the door opened. Even though Ethan had seen many naked women, a new one always got his blood pumping. Momo walked in wearing only a small towel that barely covered her chest. Her skin was flushed pink from the hot water and embarrassment.
She was stunning—slender waist, firm breasts that were too large to fit in one hand, and a round, perky ass. Ethan's breathing grew heavy as his eyes traveled down. Like her skin, her "garden" was smooth and hairless, a beautiful pale pink. The "flower petals" were a gorgeous rose-pink.
"Mmm..." Momo bit her lip, her legs feeling weak under his intense gaze. She walked toward the bed, subconsciously trying to cover herself while simultaneously wanting him to look at her more.
She looked at Ethan's body—the handsome face, the defined abs, and the massive, veiny, deep-pink rod thumping against his stomach. She stared, wide-eyed. It was her first time seeing the real thing. It was much bigger than in the movies, but the color and scent were surprisingly alluring.
"Momo, come here," Ethan said, pulling her onto the bed. He stripped the towel away and pressed his heat against her. "Momo-chan, since you're so curious, why don't you take a closer look?"
He guided her head toward him. Momo instinctively tried to turn away, but his hand was firm yet gentle on the back of her head. Her lips finally brushed against the dragon-head. The throbbing life force made her resistance melt away. She didn't want to hurt him, having heard that part of a man was fragile, but she also really wanted to taste him.
"How do I do it?" she whispered.
"Like a lollipop. Suck it, lick it," Ethan guided her, stroking her soft white hair. "Just don't use your teeth. Try to take it deep..."
Momo opened her mouth and took the hot, massive head inside. Ethan let out a low growl of pleasure. "Hnnn... that's it, Momo-chan. Slide up and down... like a popsicle."
Momo felt a strange sense of achievement as Ethan praised her. She skipped the dating phase and went straight to the most intimate contact. As she grew more skilled, "Little Ethan" grew harder and larger. She accelerated her pace, her saliva dripping down as she swirled her tongue around the tip.
Ethan was nearing his limit, but he didn't want to end it with a mouth-blast yet. He wanted her first kiss and her first time. He pulled back, ignoring her confused look.
"Momo-chan, you made me feel so good, I have to pay you back. Let's change positions."
He laid her on her back and straddled her. He put his cock near her lips again, but this time he lowered his head toward her "garden." He spread her legs and licked the warm, wet slit.
His tongue flicked over her clitoris and traced her petals. The unprecedented pleasure made Momo's body jerk. "Mmm... ahhh!"
The stimulation was so strong she forgot the cock near her mouth. Ethan rubbed it against her lips to remind her. "Momo-chan, keep doing what you were doing. You can just lie back and save your strength."
"Mmuu..." She tried to speak, but the giant rod entered her mouth again. She rolled her eyes playfully and began to serve him with her tongue and lips. The "69" position allowed her aching garden to be thoroughly serviced by Ethan's tongue.
Momo, who had never been touched by a man before, quickly reached a screaming climax under his tongue. Her juices splashed as her body shook with tremors. In her haze of pleasure, she gripped his shaft and took as much as she could into her mouth, licking him like her most precious treasure.
