Chapter 449 Perseverance*


Edited by: Kanaa-senpai


 Aki lowered his head and took Seris’s sweat-dampened ear between his lips, his tongue slipping inside to trace and nibble.


 ”Seris,” he said quietly, “the cultivation’s almost done. Get ready…”


 ”Mmgh…”


 Seris shook her head wildly. She’d been fully taken by Little Aki, and now—to be struck again by the burning heat of Life Essence at the very peak of cultivation—she knew the last shred of her fight wouldn’t survive.


 But Aki gave her no chance to say no. His hips moved faster, each thrust driving deep into her core, and Seris’s mind melted into joy within seconds. She could do nothing but gasp.


 At this moment, Aki could have asked her for anything, and she would have agreed.


 Instead, he slowed down. He pulled his swollen, hard Little Aki out inch by inch, then sank it back in just as slowly.


 The maddening pace made the golden-haired Hero schoolgirl curl up completely. She grabbed his arm, desperate. “Aki…-sama… please, faster… don’t go so slow, it hurts… please…”


 Aki didn’t listen. He drew out her suffering on purpose.


 He wouldn’t use this moment to get promises from her. Even if she agreed now, once she came to her senses, she’d hold it against him. And even if her strict sense of justice forced her to keep the deal, it would leave a thorn in her heart.


 Unless Aki planned to break Seris down into nothing but a pleasure-seeking husk—useless for anything but the bedroom—this wasn’t the time for that kind of training.


 He looked down at the pink, soft flesh clinging so eagerly to Little Aki, the soft petals turned inside out from the Great Dragon’s ravaging. The huge, veined shaft grew even harder.


 ”My dear Hero-sama,” he said, “didn’t you just say you couldn’t take it? Maybe I shouldn’t complete the final step of your cultivation. The results are already several times better than your usual training anyway.”


 Even as he spoke, he began a slow, lazy rhythm again, his pace gradually quickening.


 Seris was going crazy. Half-conscious, she reached for Aki’s abs, rocking her hips to meet his thrusts faster. Her long legs, clad in torn black silk stockings, wrapped around his back, instinct teaching her how to seduce.


 ”Aki… haaah… Aki-sama… cultivation can’t be left halfway… wuu… you’re the one who said you’d help me… Aki-sama, give me your strength one last time…”


 Hearing those words from the girl beneath him, Aki stopped teasing. He pulled her full, pale body tight against him, his tongue slipping into her reddened lips.


 As they kissed, he pounded into her over a hundred times, until he could hold back no longer.


 Under the wet, watery gazes of Ravel and the other three women, Aki held Seris’s moans with his mouth, kissing her with fevered heat, while the Great Dragon shot deep inside her womb—pumping Life Essence into the pure, untouched Flower Palace.


 Seris’s flat, smooth belly swelled slowly. Vast Life Energy spread from the Flower Palace, rushing through her body.


 The Life Essence filled with Aki’s presence turned into the purest Spiritual Power, raising Seris’s strength continuously. Its overwhelming quality even made her own cultivation energy into something thicker, smoother than before.


 Seris was drowning in double pleasure—physical and spiritual. The joy of her first Dual Cultivation took her, so completely that she didn’t notice Little Aki inside her stayed fully hard.


 Aki pulled his tongue from her lips, and the freshly satisfied Little Aki began moving within her passage again.


 Feeling the movement inside her, Seris blinked dazedly. Before she could react, Ravel spoke up from the side.


 ”Aki-sama, she’s been enjoying herself forever, and she already got a Life Essence shower. Time to switch~”


 The golden-haired Devils noble wrapped her arms around Aki from behind, pouting as she whined.


 Xue and Isabella said nothing, but the thought was clearly there. Though with their position, they couldn’t be as forward as Ravel.


 ”Sorry, sorry… I got carried away…”


 Aki grinned sheepishly, unable to resist one last squeeze of Seris’s black-stockinged thighs. He rolled over, pinning Ravel beneath him and parting her long, snowy legs to begin a fresh round of cultivation.


 Aki’s likes were no secret, but the scene only showed Ravel and the others that they’d need to stock more black silk stockings for next time.


 As Aki and Ravel began Dual Cultivation, Seris slowly came back to herself.


 Feeling the strange feeling between her legs, the color that had just returned to her face flushed bright red again.


 But she realized with surprise that she felt no regret, no fight. The Life Energy spreading through her belly made her feel warm, safe, and deeply happy.


 Mm. It’s definitely because of the fast improvement in strength. It has nothing to do with pleasure or comfort!


 After this inside justification, Seris quietly joined the watchers, waiting for her next turn.


 Time flew when you were having fun. Even with Seris added to the mix, Aki stayed firmly on top in the five-person battle—one man against four women.


 In terms of cultivation level and experience, Ravel and the others together were no match for him.


 Several rounds later—after Seris had been filled in all three openings, upper lip included—the cultivation session finally wound down.


 Ravel, Xue, and Isabella fared slightly better than Seris, but not by much.


 Aki had paid special attention to Seris, focusing on the newcomer schoolgirl and those sexy black-stockinged legs, but personal body also played a part.


 Xue and Isabella were lower in cultivation, but their taking in ability was exceptional. They’d used the energy first to fix their bodies, then to get back their strength, and only afterward began storing Aki’s Life Energy, letting them take more.


 Ravel, meanwhile, was purely strong—and her Phoenix Clan flame ability gave her a natural edge in making Life Energy better. Otherwise, with her small frame, she’d have fallen first.


 The half-day of continuous cultivation, together with four girls’ Primal Yin, pushed Aki’s strength further. He reached the peak of High God.


 One more break—one more forced push—and he’d hit Sub-Dragon God level.


 Though not as big as a life change, it was still a major turning point. Following normal cultivation methods, even with Dual Cultivation’s boost, he’d need another eight to ten years to reach it.


 ”…Hm. Guess I really do need stronger beauties to cultivate with, huh…”


 Amount could make up for quality—but the numbers needed would be crazy. And each Dual Cultivation session took roughly the same amount of time. Mass-production simply wasn’t good.


 Still, winning over powerful women wasn’t easy either.


 ”Yeah, better to focus on training Rias and Mio and the others. With their main character-level talent and luck, they’ll improve quickly. And I get to enjoy the process of raising them while I’m at it.”


 Aki looked at the four beautiful schoolgirls lying before him, his thoughts moving.


 Raising them while cultivating—and looking for new female powerhouses—didn’t clash. If the chance came, he’d do both at the same time.


 Just then, a knock came at the door.


 Aki’s attention snapped back instantly.


 Through the curtain gap, he saw the moon was already high. He’d warned everyone not to bother him, but tonight had an unexpected addition.


 As he’d thought, Nonaka Yuki was at the door.


 ”Aki… how’s Seris?”


 The girl’s cool voice carried a faint hesitation. Seris had been in Aki’s room for hours. Yuki couldn’t be sure what had happened.


 For any other beauty in the mansion—even Sephie—Yuki would have thought they’d ended up together. But this was a Hero schoolgirl from Vatican, meeting Aki for the first time.


 She couldn’t quite believe it.


 Anyone who didn’t know Seris couldn’t imagine the straight-laced, serious girl would give in so easily.


 On the other hand, Yuki didn’t think Aki would be in a hurry to make a move on Seris either.


 That part, she’d guessed right. If Seris hadn’t started it, Aki would have held back despite his want for those black-stockinged legs.


 But spending hours in that situation—Yuki couldn’t imagine any woman holding out.


 So, as dinnertime came near, she’d decided to knock and test the waters.


 Hearing a familiar voice outside, Ravel and the others simply lowered their volume, careful not to break Aki’s conversation.


 Seris, however—as the subject in question—panicked at Yuki’s meaning. She held back her moans, even holding her breath.


 After the cultivation ended, she knew exactly how wild she’d been.


 Before coming, Seris had looked down on the Nonaka sisters, thinking they’d disgraced the Heroes. But her own behavior was even worse than theirs.


 The Nonaka sisters had fallen slowly over nearly a month. Meanwhile, Seris—full stop—had completely given in under twelve hours.


 But unlike the Nonaka sisters, Seris still hadn’t given up on her mission from the Hero Clan. She hadn’t given up her Hero identity.


 Otherwise, she wouldn’t have felt the deep need to hide her fall from Nonaka Yuki.


 Aki saw through her instantly. The truth was, half of Seris’s quick giving in was to better do her watching mission.


 Better to join in than to watch Aki’s Dual Cultivation sessions get tormented day after day. Under the cover of watching, she wouldn’t even need to switch out—she could cultivate daily, pushing her power fast.


 As for the pleasure…


 It wasn’t giving in if it was part of the mission, right?


 ”Seris, huh…”


 Aki looked at the blond Hero schoolgirl, who was covering her mouth and shaking her head wildly at him. He smiled. “She’s doing great. Not only did she finish her mission, but her strength improved too.”


 Nonaka Yuki blinked, then understood.


 She knew about Seris’s mission. With Aki’s suggestive words, the result was clear.


 The girl’s cheeks flushed slightly, her cool tone softening.


 ”Then Seris-san probably doesn’t need dinner either, right?”


 Though said as a question, Yuki’s tone was sure. From experience, after Dual Cultivation with Aki, there was no room in her stomach for food.


 Aki looked at Seris’s swollen belly and grinned. “Of course. Eat without us. And could you prepare a room for Seris?”


 Seris had said she’d watch Aki 24/7, but she’d still need privacy for showers and changing. Aki didn’t mind her following him, but he wouldn’t make room for her.


 If her watching slipped due to personal matters, that was her problem, not his. Not stopping her was already kind.


 Seris realized she’d been found out, dropping her hand from her mouth and glaring at Aki with a mix of shame and anger.


 After dealing with Yuki, Aki was wondering how to pass the time. The night was long, and waiting for them to recover sounded boring.


 But Seris’s flustered, angry look lit his interest again.


 ”Oh? Seems like our Hero-sama isn’t happy with my answer?”


 Aki grabbed Seris’s smooth, black-stockinged feet and pulled her toward him. The proud, hard Great Dragon found its way into her Secret Garden with practiced ease, drawing a low gasp from her lips.


 ”If you’re that unhappy, Seris, why not go explain it to Yuki yourself?”


 He made a show of reaching for the door.


 Nonaka Yuki hadn’t walked far. If he opened it, Seris’s wild state would be on full display.


 ”Mmgh… don’t…”


 Seris started to speak, but Aki drove into her twice, then dipped his head to kiss her—loud, wet sounds filling the room. She tried to push his tongue out with hers, but his own wrapped around it strongly.


 ”Mmhn…”


 Seris accidentally let out a sound, immediately holding Aki’s arm in panic.


 She was terrified Yuki would hear, or that Aki would actually open the door.


 For Aki, sharing a bed and cultivating together was old news. Besides Sephie, almost all the mansion’s beauties had seen each other bare.


 If today hadn’t been Ravel’s big occasion, peaceful “alone time” would have been impossible.


 But for Seris? It was too much.


 Ravel and the others had no choice, but being shown in such a state before Nonaka Yuki—a former fellow Hero—would shame her beyond what she could take.


 Aki laughed, lifting his hips to pound into Seris’s soft garden.


 With each thrust, Life Essence and her own honey leaked out, dripping down between them.


 Ravel and the others watched Seris getting Aki’s attention with a touch of envy, but this time they didn’t ask for fairness. They were more than happy for him to spend time and energy on Seris—it gave them longer to recover.


 At this stage, the newly taken girls were deeply impressed. There was still a whole night ahead—plenty to go around.


 Watching Seris twist beneath Aki, the three women actually felt a bit sorry for her.


 Poor thing—her legs can’t even close, and he’s still going…


 Seris might have been suffering, but she was enjoying it just as much.


 Aki kissed her deeply, speaking between breaths: “I agreed to help with your watching mission, but I’m not required to help with anything else. If you change your mind, speak up anytime.”


 At this moment, Seris didn’t have the mental room for any of that—let alone notice the slight mockery in his words.


 And Aki was right. Watching wasn’t alliance—it wasn’t even working together.


 Once Nonaka Yuki left, Aki carried Seris around the room, still inside her, cultivating as he walked.


 He was too deep in pleasure to stop. He wanted to keep Dual Cultivating day and night without pause.


 But Seris was fading.


 She was exhausted—too tired to lift a finger, her voice raw from screaming.


 ”Aki… Aki-sama… wuu… I can’t…”


 ”I really can’t…”


 The feeling of the burning-hot, thick Little Aki rubbing inside her soft garden was almost too good to bear, but Seris simply couldn’t go on.


 Aki slowed down, lowering his head to kiss her gently.


 ”Ravel’s bedroom has its own bathroom. I’ll help you wash up.”


 Carrying her with him—still inside her—he took her into the connecting bathroom.


 He turned on the shower, and the two of them stood under the water together, bare. The ultra-thin black silk stockings that had lasted through the afternoon were now torn beyond repair. At some point during Aki’s handling, they’d been taken off completely.


 ”Just rest. I’ll take it from here.”


 Aki held Seris under the spray, holding her bottom as he drove up into her.


 ”I haven’t had my fill yet—you just relax while I get mine…”


 The cultivation benefits for Seris had maxed out. For Aki, there was still some effect, but not much. So he didn’t need to think about anything else—just pleasure.


 Pure enjoyment was actually more satisfying.


 Ignoring the Hero schoolgirl’s weak protests, Aki lifted her left leg over his shoulder, his eyes fixed on the pink, swollen flesh at the top of her thighs, turned inside out by his nonstop pounding.


 ”So beautiful… so good…”


 Seris’s energy was spent. She couldn’t fight however he placed her.


 In the warm bath, she drifted in and out of sleep—and eventually fell asleep.


 When she woke, she was lying in bed. Both her thighs were hooked over Aki’s shoulders, and the hard, swollen Great Dragon inside her belly was still thrusting wildly, in and out.


 ”Ah… Aki…”


 Aki smiled and rubbed her cheek. “Good morning, Seris-chan. Hold on a sec—after morning practice, I’ll introduce you to everyone else.”


 The night before, after Seris passed out, Aki had taken one last pleasure-filled release, cleaned her up, and then gone to battle with Ravel and the other three.


 Even with Devils’ bodies and all their edges, Ravel and the group couldn’t hold out until sunrise.
