Chapter 126 Ultra-thin Black Silk


Edited by: Kanaa-senpai


 Now that he understood the full picture of the situation, a general plan had already formed in Aki’s mind.


 The only thing he was missing now was the right opportunity.


 He let out a sudden shudder as his Great Dragon spat out a milky-white, scorching hot dragon’s breath, filling Mittelt’s small mouth until her cheeks were completely distended.


 ”Yuuma-chan¹ mentioned earlier that the higher-ups wanted you all to investigate a dangerous Sacred Gear… how is the progress on that?” Aki asked.


 ”The new mission we received this time is-“


 ”Wait a second,” the tiger-toothed loli interrupted, swallowing the last of the Essence and rubbing her jaw.


 ”Let me be the one to talk. Vana, you come over here. My mouth is already sore.”


 Aki couldn’t help but mock her.


 ”You’re already A-rank, yet your mouth gets sore after just this much? Who are you trying to kid?”


 Mittelt stopped rubbing her cheeks and flashed a dangerous smile, her sharp little tiger teeth glinting coldly under the bathroom lights.


 She glanced down at the still-erect Little Aki, looking like she was ready to pounce.


 (Although I’m confident Little Aki wouldn’t be harmed as long as Mittelt didn’t use her Mana, looking at those razor-sharp teeth makes me think it’s better not to test his luck.)


 He stood up straight, grabbing the tsundere loli’s slender waist and pulling her into his chest.


 ”Vana, I’ll leave the rest of the cleaning to you,” said Aki.


 ”Mhm,” Kalawarner replied.


 Kalawarner didn’t let herself get greedy for a taste.


 Amano Yuuma was still waiting outside, and they couldn’t afford to waste any more time.


 The blue-haired, busty beauty maintained a cold, serious expression as she washed Aki’s back.


 However, the deep flush spreading across her fair skin revealed that her heart was far from the calm she projected.


 As Aki held Mittelt, the two of them discussed the details of the mission while scrubbing each other down.


 ”Uesugi, you seem to be very focused on this ‘dangerous Sacred Gear’ lately,” Mittelt asked.


 ”Call me Master,” Aki said.


 Aki delivered a sharp smack to her perky, rounded buttocks, the sound echoing clearly in the room.


 Although he had grown used to the name Uesugi Aki, when he was with those close to him, he preferred them to use his title or his first name rather than his family name.


 ”Ooh… fine, Master~” Mittelt replied.


 The blonde tsundere loli had been thoroughly broken in by now.


 Her sensitive rear having been toyed with, she let out a soft moan and obediently slumped into Aki’s embrace.


 ”The reason I’m watching that Sacred Gear, of course, is because I want it for myself,” said Aki.


 Aki caressed the girl’s delicate skin, speaking slowly.


 ”A so-called ‘dangerous’ Sacred Gear is only a threat to me as long as it’s in someone else’s hands. If it’s mine, the danger belongs to everyone else.”


 ”Is that ritual you’re preparing meant to be used for seizing this Sacred Gear?” Mittelt asked.


 (I can’t be entirely sure if this specific item is the Boosted Gear yet, and I don’t know how to explain my knowledge anyway, so a convenient excuse will have to do.)


 ”Initially, I just wanted to find a powerful Sacred Gear that suited me, but I didn’t have a reliable way to track one down. Since you happened to have intel on a powerful one, I figured I’d just settle on that,” Aki explained.


 ”Mm… ah…” Mittelt moaned.


 With her curiosity satisfied, Mittelt spoke through her heavy breathing.


 ”Then your luck is actually pretty good. After we turned in the previous mission items, the new orders from above were specifically about intel regarding that dangerous Sacred Gear.”


 ”What kind of intel?” Aki asked.


 In his excitement, Aki’s hands gripped her a bit too firmly, making the tsundere loli moan and gasp uncontrollably.


 ”Ooh… mm… Master, be gentler~” Mittelt cooed.


 ”Only Lady Raynare knows the specific details. If you want to find out, you’ll have to ask her yourself.”


 ”After all that fuss, it turns out you don’t actually know anything,” Aki said.


 Aki gave the blonde loli’s n**ple a forceful pinch, speaking with a hint of annoyance.


 ”Fine, get down. Remember to wash your mouth out properly, otherwise, I’m not kissing you later.”


 Mittelt turned on the showerhead, grumbling playfully.


 ”I know, I know~ Honestly, it’s Master’s own ‘stuff,’ yet you’re acting like it’s gross.”


 Aki turned around to help Kalawarner wash her body, ignoring the loli’s complaints.


 (Next time we do some Dual Cultivation, I’ll make sure this little tsundere gets a taste of her own nectar to see if she finds that gross.)

 After washing away the sweat and grime of battle, Aki led Kalawarner and Mittelt into the bedroom of Amano Yuuma.


 When the three of them entered, Yuuma was already waiting on the bed.


 She had changed into a set of translucent lace lingerie designed to boost the efficiency of Dual Cultivation, paired with ultra-thin Black Silk stockings.


 Her massive breasts rose high, forming a stunning curve, the fair flesh appearing even more seductive through the black, see-through lace.


 Moving down past her ribs, her waist was so slender it could be held in one hand, her belly flat and toned.


 But as the lines of her body reached her hips, they expanded beautifully into two plump, delicate butt cheeks that stretched her transparent panties to their absolute limit.


 Her already perfect, long legs looked incredibly soft and supple wrapped in the Black Silk.


 Her small, dainty feet moved playfully, her pearl-like pink toes occasionally snagging the fabric of the stockings, making it impossible for Aki to look away.


 It seemed that not only the blue-haired girl, but even Yuuma had firmly memorized the fetish Aki had confessed to last time.


 ”Yuuma-chan, you really know what you’re doing. I love this,” Aki said.


 Aki couldn’t wait a second longer, pouncing onto her alluring body and capturing her pink lips, sucking on them with total abandon.


 A moment later, breathless from the kiss, Yuuma pushed him back slightly.


 ”Don’t… don’t get the wrong idea,” Yuuma said.


 Aki caressed the smooth, delicate texture of the Black Silk.


 ”The wrong idea about what?”


 Yuuma turned her head away, unable to withstand his burning gaze, trying to sound composed.


 ”I didn’t put these on for you. I… I just wanted the Cultivation efficiency to be a bit higher, that’s all.”


 ”Yuuma-chan, one Mittelt is enough for the tsundere act. That style doesn’t really fit you,” said Aki.


 Looking at the black-haired, big-breasted beauty before him, Aki decided to put the Sacred Gear talk on hold.


 Without giving her a chance to respond, he kissed her inviting red lips again.


 He then directly lifted Yuuma’s long, shapely legs, pressing them together, and shoved Little Aki right between those soft, plump thighs.


 Feeling the Great Dragon surrounded by the elastic, soft flesh of Yuuma’s silk-clad legs, Aki let out a groan of pure pleasure.


 He propped her silk-covered legs up and knelt on the bed, his hips beginning to thrust rhythmically.


 He used the girl’s pressed-together thighs as a surrogate honey hole, thrusting into them with all his might.


 Compared to the tight, wet Flower Valley, the sensation of the Black Silk legs was just as incredible-rounded, long, and firm yet bouncy.


 With the addition of the high-end, ultra-thin silk, the physical pleasure and the visual shock sent Aki’s excitement through the roof.


 The act of purely pleasuring Aki made Yuuma feel a bit shy, causing her silk-clad legs to squirm occasionally.


 This, however, gave the Great Dragon an even tighter, shifting grip, as if she were indirectly helping him by stroking it.


 Aki gave in to his instincts, hugging Yuuma’s Black Silk legs while thrusting his waist and stroking her beautiful feet.


 The Great Dragon slid in and out between those soft, full thighs.


 The massive, purple-red head would occasionally peek out from between her legs, coating Yuuma’s pink Flower Valley and fair belly with the pre-c*m secreted from his intense arousal.


 The smooth texture of the high-end silk, the softness of the girl’s flesh, and the psychological thrill caused Aki’s lower back to go numb with pleasure very quickly.


 ”Yuuma-chan… I’m going to come… I want to do it just like this…” Aki groaned.


 Looking at the scorching Great Dragon friction-burning her thighs, Yuuma’s face was beet-red.


 ”You pervert… do you really love my legs that much…?”


 After teasing him, she let out a low whimper of agreement and squeezed her legs together even tighter.


 ”Since you like it so much… I’ll allow you to finish like this, just this once…”


 With Yuuma’s active cooperation, Aki finally lost control.


 With a low roar, he erupted, spraying his thick, scalding Essence deep within the thigh-tunnel.


Splirt-


 Perhaps because he was so overstimulated, the Great Dragon’s breath lasted an exceptionally long time.


 Huge amounts of milky-white Essence splashed out, leaving white streaks all over Yuuma’s body.


 Because the head was aimed upward, her pure yet seductive face, her full breasts, her smooth stomach, and her pink Flower Valley were the primary targets.


 Feeling her entire body covered in the hot Essence, Yuuma trembled slightly.


 Her exquisite face turned so red it looked like it might bleed.


 She slowly peeled off the lingerie and stockings now soaked in white liquid.


 ”Alright, that’s enough. Now we need to start the Cultivation properly,” Yuuma said.


 (That’s basically her admitting that the previous act was pure lust, but since I already enjoyed myself, I’m not about to call her out on it.)


 ”Sure. I just hit S-Rank a few days ago. During this Cultivation, you all should see a massive jump in your power,” Aki replied.

Notes:


• Aki – A handsome, tall, and muscular sixteen-year-old freshman at Kuoh Private Academy, adopted son of the Takamine household, with sharp features, broad black bat wings, a barbed tail, and crimson-flecked eyes—once timid, now radiating dominant, predatory confidence. Master of Dual Cultivation, he channels immense stamina and life-energy transfer, mentoring Mittelt and Kalawarner while restoring the latter and plotting to steal Issei’s Boosted Gear. Romantically entangled with both of Kasumi’s daughters and Kasumi herself, he exudes a calm, weary sophistication amid family drama, admiring legs and feet, his “Great Dragon” symbolizing his physical and sexual dominance.

• Mittelt – Blonde, petite Fallen Angel with twin tails, tiger‑tooth grin and black‑and‑white maid uniform, jade‑white‑red aura. A‑rank, tsundere servant of Raynare and Kalawarner, trapped in Mount Mitsu’s barrier. She serves Aki as maid, digests life energy to boost Mana, and playfully vies for his attention.

• Yuuma – Amano Yuuma, the fallen angel Raynare, is a striking, curvaceous beauty with long black hair and violet eyes. A former Grigori operative, she is a petite, tsundere warrior who wields light magic. After defecting to become a Pawn in Rias Gremory’s peerage, she now serves Aki with obsessive, yielding devotion, sharing a deep physical and spiritual bond through their frequent dual cultivation.

• Y – The first initial/part of the name Y Ddraig Goch.

• Vana – An alias used by Kalawarner, a fallen angel subordinate to Raynare. She often wears a mature, seductive outfit or standard human disguises.

• Kalawarner – Tall, curvaceous fallen angel with fair skin, long blue hair, emerald eyes and a large, round bust. Associate of Raynare, subordinate to Aki, weakened and needing mana infusions. Loyal older‑sister‑type to Aki, recently A‑Rank, grateful yet insecure. Cold‑serious, internally aroused, she rides Aki to speed his cultivation.

• Amano Yuuma – Yuuma Amano, also known as Raynare, is a fallen angel disguised as a high‑school girl to observe Aki. She has long black hair, white skin, slender waist, crystalline earlobes, and pitch‑black feathered wings. She wears a revealing black leather outfit covering only vital spots, black leather boots, and exudes a glamorous, provocative aura.

• Amano – Raynare, a fallen angel, masquerades as schoolgirl Yuma Amano in Kuoh Town. She has long black hair, a striking figure, and adopts the Amano surname to hide her true self. After reaching A-Rank with Aki she gains a black-belly nature and can instantly change clothes. The Amano name links her to the Fallen Angel faction and to Yuuma.

• Uesugi – Aki is slender, silver‑haired with calm, resolute eyes. He bears the Uesugi name, an A‑rank Stray Devil whose pragmatic, occasionally ruthless nature Kalawarner notes, linking his lineage to the Kurogane line and the Takamine family’s household dynamics.

• Uesugi Aki – Family name of Aki.

• Raynare – A black‑haired, voluptuous A‑rank Fallen Angel, known as Lady Raynare and alias Amano Yuuma, sports obsidian wings and light spears. She shifts between an innocent schoolgirl guise and a lecherous cultivation form, leads a small cadre, and mentors Aki—her master‑disciple bond turning predatory. Irked by Mittelt’s sloth, she holds intel on a dangerous Sacred Gear and participates in a high‑stakes ritual to strip it.
