DxD: Milking System

To begin, Jin activated the Lactation Fog once again to ensure that Aika could produce milk.

As far as his knowledge went, Aika was still a virgin; certainly, she had never gotten pregnant or lactating. Jin himself didn't really know how women produced their milk, so he used his Lactation Fog to the fullest, filling the room with pink fog.

Aika looked at Jin feverishly, her braided hair was let loose, and she looked more beautiful compared to when she tied her hair. Her glasses were also off as Jin erased them alongside her clothes when he changed the room.

Maybe the pheromone was at work, but Jin didn't believe that. Aika was always beautiful if she didn't say anything. Jin always believed that.

So he leaned his face closer to Aika and whispered to her ear.

"Are you ready for the milking session?"

"Ugh, p-please don't tease me. Even I am also a girl, you know."

"I know," Jin answered, pulling his face a bit away, then looking at Aika straight to her eyes.

She was panting in expectation, and Jin's switch had been flipped.

Even though he was a cool guy on the outside, he was still a man. His goal was to drink milk, but who said he wasn't allowed to do something else?

Though he wanted to keep his goal as his priority for now. 30 minutes were far from enough, so he wanted to extend the duration of the room first by increasing his System's level before he did something more than milking the girl.

And to do that, he needed milk.

Jin's hand moved to Aika's breast, squeezing it.

"Kya!"

She moaned in surprise, but she didn't seem to hate it. Instead, she pushed her chest forward, urging Jin to continue squeezing it.

Jin didn't shy away. He squeezed even harder the twin mountain of Aika with both hands. It fit perfectly in his hands, and Aika moaned in pleasure as he played with her breasts.

"Hnn, there. You can be rougher, Jin."

"You don't need to say that."

He started to explore Aika's body, caressing her with his left hand while his right hand kept squeezing her breast, stimulating her to be able to lactate.

Even with the effect of the fog, lactation didn't happen so suddenly. Jin needed to stimulate Aika's breast at least to gush out the first milk, and that was what he did. He also used the Golden Hand to send more pleasure to Aika.

He kept fondling her breasts for more than a minute. Aika pleasured moans and pants filled the room.

Jin grinned as he kept doing what he did, but he was somehow unsatisfied and was carving some milk. Was it the influence of the System? But he wanted to drink milk as fast as he could.

So, he moved to Aika's breast and sucked her nipple.

"Ahn! S-So sudden!" Aika protested, but Jin ignored her.

Her hands were tied, so she couldn't do anything to Jin no matter what he did. The Milking room was designed for Milking, and Jin was the owner of it.

For Jin, Aika was now just a cattle ready to be milked.

'How much longer do I have to play with her breast until she lactates?' Jin thought.

As he thought that, he squeezed Aika's breast even harder, which made her yell.

"AH! It hurts!"

Even so, Jin kept playing with it, and finally, a white liquid began to drip slightly from the tip of her nipple.

"Huh? W-What is this? Ahn, t-this is!"

Jin pulled his face away and grinned.

"Oh? It seems that you have lactated." Jin said, squeezing Aika's breasts with both hands, which made the white liquid, milk, squirt out from her nipple.

It was an amazing spectacle for Jin, and he didn't wait for something else as he said, "Thanks for the drink."

He sucked her nipple to get the milk that she squirted.

'It's sweet.' He thought as he kept drinking the milk. A gulping sound was heard alongside the moan inside the pink room.

[You drink a mouthful of milk. As a result, your lifespan increased by 3 Days. You gained 3 EXP]

[You drink a mouthful of milk. As a result, your lifespan increased by 3 Days. You gained 3 EXP]

[You drink a mouthful of milk. As a result, your lifespan increased by 3 Days. You gained 3 EXP]

[You have gained skill: Basic Mathematics from Kiryuu Aika.]

[You have gained skill: Size Scouter (Breasts) from Kiryuu Aika.]

The notification appeared beside him in the form of a long blue panel, creating a log.

He somehow got two skills, which were useless for fighting but useful for judging which breasts were ideal to be milked. He remembered Aika boasted that she could calculate a male's dick size, but it seemed like he got her skill, but the System changed it to calculate breast size instead of dick size.

'It's useful.' Jin thought to himself as he continued drinking Aika's delicious milk.

Aika kept moaning in pleasure, her legs were kicking around, but she kept squirting the love juice from her crotch and milk from her nipple. Her eyes were blurred. All she could think of was the pleasure of getting milked.

"I-I feel strange! I-It's too good! I am cumming cumming!"

Aika squirted a lot of love juices from her crotch as her body arched. Jin pulled away from her nipple, creating a saliva trail connecting his mouth with her nipples.

The milk seemed to have stopped gushing out; it seemed like it was already stopped. Jin was satisfied as one mouthful had extended his life for 3 days, and he drank a lot of milk.

At that moment, a notification popped up in front of his eyes. This time with a sound to get his attention.

[Ding! The Milking Room will disappear in 30 seconds! Finish your business before it disappears!]

'Huh?! I already spent 30 minutes drinking from Aika?' Jin thought, surprised.

He then looked at Aika's figure. Her body was filled with a mixture of breast milk and sweat as she panted hard, while her crotch was wet from her love juices. The bed was also wet from the mixture of the three, and Jin just realized that after he snapped out.

"Haa… T-That was amazing…" Aika muttered, looking at Jin with a gaze full of love.

Jin smiled in response without saying anything. She would forget about all things that happened in this room; he had set it to be like that. He didn't want his System to be known before he had the power to protect himself.

So he whispered as the clock in the blue panel slowly went down. 25, 24, 23...

"Did you have fun, Aika?"

"Yes… That was amazing, Jin. But, where are we?" She looked around, still panting, but she had regained some of her senses.

"It doesn't matter anymore." Jin replied, looking at the countdown that had hit 3. "As you will forget everything. Good night, Aika."

"Huh?"

As Aika let out a confused sound, the room disappeared, and they were back in the park; Aika sat on the bench while Jin stood behind her.

She looked at Jin with a blank gaze before she snapped out.

"Huh? What am I doing?" She asked, confused.

Jin smiled at her and said, "You just had a dream, maybe? You suddenly closed your eyes and fell asleep. Why don't we end today and let us go home?"

"Good idea." She answered before letting out a yawn. "It seems that I am also tired."

"Then, let's go home, shall we? I will escort you."

"Sure. Thank you, Jin."

"You're welcome." He answered with his brightest smile.

Secretly, he glanced at his left, which showed his lifespan.

---

Lifespan Left: 0Y 9M 5D

---

His lifespan had increased by 3M and 3D, meaning he had drunk 31 mouthfuls of milk. His EXP also progressed smoothly, which made him happy.

'I think I can get addicted to this.'
