Chapter 56: The Milkman's Ascent

Takumi felt a shiver of ice go down his spine as Serafall breathed heavily, it felt like the room got several degrees colder just by his statement. At that moment he felt like what it felt like to be a sexual prey.

"Mou~ what am I going to do with you Taku-tan~? If you wanted to touch your big sis' breasts you could have just asked me you know~? No need to hide behind Alchemy."

"N-no, I mean it is for alchemy, breast milk is actually one of the most potent alchemic catalysts and one from an Ultimate Class Devil like you would aid in my research tremendously, alongside some blood, spit and similar materials." That seemed to dim Serafall's mood ever so slightly, to a minuscule extent even. But she perked right up.

"But you still need to milk me! Come on what are you waiting for!? Let's do lewd things together Taku-tan!"

Takumi's eyes twitched.

'Taku...tan?'

'Well, it's better to have a closer relationship with a Satan than not. Right, pal?' Chimed in Ddraig from Takumi's subconscious seeing his abnormal mental distress.

'Yeah but... Taku-tan? I got demoted from the Dragon Alchemist overlord that can change the tide of history to an adorable little brother just by jokingly referring to her as Sera-nee? What the fuck is wrong with this world?'

Ddraig mentally shook their head in understanding.

'Pal, throughout my long existence I have learned a lesson. For most beings, how big of a nutcase they are is proportional to how strong they are. Coincidentally this applies to you as well.'

'Hey I am n-' Ddraig cut him off, already prepared for the response.

'Pal, there is a reason why self-mind control was not created. You have stuffed 3 sacred gears inside yourself, one of them a Longinus inside of you while you were still human. You asked for the strongest Satan in history for his wife. Now you are asking the strongest female devil to milk her breasts. In comparison, an older sister fetish pales in comparison.'

Takumi chose not to respond, just cutting off the connection while Ddraig smirked internally and brought up the mental scoreboard.

|Takumi | Ddraig|

|----------------|

| I | III |

Sighing mentally in exasperation Takumi felt a hint of kinship with Sona forming at that moment.

"Okay, Sera-nee, whatever you say. Let's go to my workshop." Well, at least he would get to milk Serafall who is hotter than the sun. But why did he feel like he had lost as Serafall followed him intently?

✧—•✦•—✧—•✦•—✧—•✦•—✧

Serafall burst into the room with a haughty smile. Wearing a white and pink cow print micro bikini with matching stockings and even gloves, she really liked the design and she definitely enjoyed it and was anticipating what was to come.

Although it shamed her a little to admit Serafall was still a virgin, she was raised as the heiress of the Sitri clan and before she got to marry she was fighting in the civil war and by the time the war was over she was one of the rulers of her race. When she held a position as important as hers she couldn't find anyone to do it with, especially no one belonging to the noble houses, their positions were below hers and it would become a pain to deal with. Technically she could have slept with her fellow satans but...

She genuinely didn't know if Ajuka actually had a sexual drive, he hadn't once seen him express any interest in any female of any race. Falbium was a no without question. And Sirzechs, somehow as the strongest devil in history was monogamous.

Plus she preferred Takumi's type much more.

Seeing Takumi's heavy gaze laced with lust she felt her panties get damper while Takumi nodded and fished out a white potion in an ornate bottle.

"Woah, Takumi what is that potion? Ooh~ is it a naughty one?" Hearing her words Takumi simply shrugged his shoulders.

"It's the Boosted Advanced Temporary Lactation Potion X. I had to put a LOT of elbow grease into this to get it to work on someone as strong as you are but it should still work for at least an hour." Serfall grinned, lactation? How kinky, big sis likes. Maybe she would even be able to convince Taku-tan to let her give him a breastfeeding handjob.

Serafall crossed, she was getting a bit too excited too early.

She was also impressed at how he managed to create a potion that managed to apply its effects on Ultimate Class devil's but she was off the clock right now. She quickly grabbed the bottle and downed it in one go, feeling the thick viscous liquid rush down her throat as she felt a heat settle within herself and her breasts feel heavier.

That was so hot.

~~~~~~r18 Start~~~~~~

Then Takumi led her to the milking station and gently undid her top, making her large breasts, Takumi felt his divine dragon rebelling against its restraints, her breasts were large, almost as large as Rias' with blossom pink nipples that looked like they were begging for relief.

"Mmh~"

Serafall felt like she was melting like putty in Takumi's skilled hands as they gently caressed her breasts, making her core feel even warmer as she rubbed her things together. As he lightly squeezed her breasts she felt a unique pleasure as milk slowly dribbled out of the ends of her nipples.

"Mou~! You are too gentle Takumi-kun!" She liked to do the teasing not be teased herself!

In response Takumi lightly flicked one of her nipples, making her arch her back as pleasure ran down her spine like lightning

"Patience Sera-nee. I need to work my magic carefully." Takumi said with a sly smirk that sent even more shivers down her spine. He gently tweaked her nipples, rolling her pink buds firm from arousal around his fingers, enjoying his power over her.

"Hnnnh~~" Sera moaned involuntarily as Takumi firmly yet gently pinched her nipples and drew milk from her breasts, the sensation was very pleasant, at this rate Sera would cum just from her breasts alone which her pride refused to let her as she gritted her teeth and tried to endure the onslaught of pleasure.

Takumi's hands moved upward to her breasts and firmly yet gently squeezed her breasts, drawing even more milk into the bucket under there. At the same time as he squeezed her breasts his pinkies tickled her nipples sending shivery down her spine and into her core, drenching her panties even further.

She watched in amazement as the bucket filled up more and more with her very own breast milk.

"H-hey~ Taku-tan, you are looking pretty pent up there. Plan on doing something about it~?" Hearing her words Takumi weighed his options. He felt like getting completely swept up in this mood was a bad idea but at the same time, the smug Serafall was right in front of him.

Take it slow, slow and steady won the race, he bargained with himself. He would not be led around with her.

Smirking he suddenly squeezed her nipples and tugged on them way harder than before, aware that he physically couldn't hurt Serafall. And the effect was instant as the expression on Serafall's face was instantly wiped as her eyes crossed and mouth hung open.

"Hnnnngh~~~!"

Takumi grinned as he saw a lot of liquid seep out of Serafall's already-drenched panties, feeling no need to waste he subtly used Dominator's Touch to collect it into a separate container. Not letting up he still played with Serafall's nipples as she came, taking advantage of her being sensitive to milk her even more as milk sprayed out wildly.

"Were you saying something? S-e-r-a--n-e-e?"

"Taku-tan, you really are ruthless ~ You wanted to punish Nee-san that badly huh? You even made me run out of breath. You are such a bad boy~ Nee-san will have to return the favour later." Serafall said while basking in the afterglow of the best orgasm of her life, at first it was somewhat of a joke but now she felt like she genuinely couldn't let go of Takumi, there was just something about him.

~~~~~~~r18 end~~~~~~

Takumi smiled back at her, guiding his face down to her leaking breasts and giving a gentle teasing lick that made her insides clench but suddenly his face went intense, prompting Serafall to tilt her head in worry and question as Takumi started intently staring at the bucket of milk.

"Taku-tan? You good?"

While in Takumi's view...

"Unholy shit."

Her breast milk... had the aspect of the Sitri bloodline inside of it.

He could make an elixir that gives himself the Sitri bloodline with it.

He could make fertility potions that worked as basically guaranteed pregnancy with it.

He could make advanced Ice and Water potions with it.

Thoughts raced through Takumi's mind at the speed of light, theory and plan after plan forming, being detailed and shut down by the second. This was revolutionary, if he managed to process materials like this his Alchemy could reach a level beyond the baby shit he was currently doing.

"Taku-tan?" Serafall was honestly feeling a little left out with Takumi staring into a bucket for 3 minutes now.

The power of Milk, it was... immense, it was almost the core of Alchemy, he was reaching something, but he knew, it was just out of reach.

He clicked his teeth internally, not enough milk huh? He couldn't get any more Ultimate Class Milk from Serafall anytime soon, high-quality stuff needed to be built up, he only got around 600ml this time. But there would be repeats. For now, he needed to experiment. Now.

"Hell to Taku? Are you there?"

"Sera, it's revolutionary. I have just found numerous uses for your breast milk that I have to test. This could change everything." Serafall was a bit taken aback by the light in Takumi's eyes, that glint felt almost dangerous to her. But that was offset instantly by Takumi grabbing her chin and giving her a hot and passionate but quick kiss making her flustered.

"Thank you Sera, I couldn't have gotten any other better gifts. Now I gotta go, if you need anything in the house ask the maids. You can keep the costume" Takumi said, speedwalking away with his milk, no literally skipping like an excited child while Serafall touched her lips.

"Geez, I made a dangerous one my little brother."

But Serfall couldn't feel any regret.

Getting up from her station Serafall stretched while smiling. She had a lot of work to do to set her new adorable brother up properly.

A/N: Serafall is a bit of a freak and it's making the freaker himself, Takumi self-conscious. They are made for each other.

And Takumi has started cracking the code, in a world like DxD where breasts rule, and Milk is King. And he just gained the cheat code to the Devil bloodlines. The Underworld is going to be turned upside down when he makes his proper debut.
