A/N: summary of the chapter at the bottom.

His eye fell on the handcuffs. Rias had used them to handcuff him to the bed and ride his face. Afterwards, she had left them in his room.

Hm. Maybe he could use them for something fun after all? Then they would serve their initial purpose.

Issei picked them up and put them in his bag.

I think I've got everything.

[I think so too.]

Our plan is decent, right?

[Our plan?]

We're a team, Ddraig. You need me just as much as I need you. Without me you're just a voice in a Sacred Gear.

[Hm. I guess you have a point there.]

Issei took the elevator down.

During their house renovation, Sirzechs had created a hidden basement filled with a few cars and a tunnel leading out. It was there in case of emergency. Only Issei and Rias knew about it. But Rias was asleep now since it was the middle of the night.

Issei met Asia in the basement. It had been very simple to get her out. Rias left the key on the door when she locked her up at night.

"This is the last one," Issei said. "Do you have everything you need?"

"Yes."

"Okay."

Issei put the bag on the backseat. Their trunk was already filled.

They had enough supplies to survive for a few weeks.

"Okay," he said. "Only one thing left to do. The most important bit actually."

Asia nodded. "I know."

"I'll wait here."

"Can't you-"

"This was your idea," he reminded her. "You said you'd steal the key for me."

"Yes, but… please?"

"Okay then."

They both took the elevator up and went to her room.

Asia slowly opened the door and went inside, followed by Issei

Their devil eyes could see well enough in the darkness.

Rias was sleeping softly. He could hear her breathing slowly.

They approached her carefully.

She was pretty cute like this. Naked, only partly covered by the blanket.

But there was no time for that now.

Asia took out a wire cutter from her pocket.

Here goes nothing.

Very slowly, she took the chain and cut it. The key slipped down and fell on the mattress.

Just as she reached for it, Rias rolled over.

Fuck. It's all over now. I'm-

[She's still asleep,] Ddraig said. [You just need to roll her over.]

She's gonna wake up if I do that.

[You could also go back to bed and give up.]

No. You can forget that. We've come this far already.

[In that case, I've got an idea.]

Issei took out his phone.

Asia mouthed something.

Trust me, he mouthed back.

She nodded.

Issei stood a bit away so the light wouldn't wake her up. He turned on his phone and navigated to the internet.

A soft noise came out a bit later.

Asia frowned. A mosquito?

Issei turned off the light of his phone, but the noise kept going. He held it over Rias face.

She mumbled something in her sleep.

He kept hovering it around her head.

She waved with her hand, mumbling a complaint.

After a few more attempts, Rias finally rolled over.

Asia quickly took the key.

Issei turned off his phone again.

They both sneaked back outside.

"That was close," he whispered.

"Yeah. But it worked."

They went to the basement with the elevator.

"Why aren't we teleporting away?" Asia asked.

"Magic leaves traces. We need to get out of reach first. And our supplies are in the car."

They arrived in the basement.

Issei got into the car and started.

He drove through the tunnel. This tunnel emerged at the edge of town, near the highway. It didn't take them long to reach it since there was no speed limit here.

Issei emerged from the tunnel. It closed after them.

Issei turned onto the highway.

"I didn't know you could drive a car," Asia said.

[He can't,] Ddraig said out loud. [I'm driving.]

"I'm the one with the physical body," Issei argued.

[Well-]

"Anyway," Asia said. "We managed to get out"

"Yeah." Issei shifted uncomfortably. "But we should keep going. We're not yet safe."

"Let's first take off that thing." She unclicked her seatbelt. There was a warning beep from the car.

"You shouldn't-"

"Shh."

Asia leaned over and took his waistband. Issei had put on loose pants because tight ones were very uncomfortable to wear with that thing on. He didn't have boxers on either.

Issei momentarily lifted his legs so she could pull his pants down to his thighs.

Asia took the lock and inserted the key.

With a click, it opened. She carefully removed the device.

Issei let out his breath. That was much better.

Asia threw the cage on the backseat along with the key.

"Does it hurt?" she asked.

"A bit."

"I'll make it all better. Don't worry." She leaned down and gave his cock a kiss.

"Asia?"

Asia shushed him again. She stuck out her tongue and…

"Fuck." Issei shivered. The car swerved dangerously. "Don't do that. I'm driving."

"No you're not. Ddraig is driving."

"Yes, but I'm the one holding the wheel."

"Sorry." She sat back on her seat and closed her seatbelt again. "You're right. It can wait."

He moved his pants back to normal.

[Why don't you press that blue button on the dashboard?] Ddraig suggested.

Button?

Issei clicked.

[Advanced cruise control activated,] a female computer voice announced.

[The computer will keep the car between the lines and at this speed,] Ddraig said. [So you can focus on your slave.]

Oh, right. Asia had agreed to be his slave. That was their deal.

"Cruise control?" Asia asked.

"It can drive on its own," Issei explained. "Apparently."

"Oh. So can I continue then?" Asia asked. "Master."

"Not like that."

"Hm?"

"You shouldn't worship my cock with so many clothes on."

"Ah. You're right, I'm sorry. But… uhm… can anyone see us?"

"Special windows. They can't see us."

"Okay."

She got undressed. Which wasn't easy to do while sitting in a driving car.

With some effort, Asia stripped down to her underwear. Then, she hooked her thumbs in her panties.

"What are you doing?"

"Getting undressed?"

"Bra first."

"Oh. Of course, sorry."

She reached back and unhooked her bra. Then she rolled down her panties and got out of them. She was completely naked now.

"Asia," he said.

"Yes, Master?"

"Are you sure about this? You don't have to be my slave. I know you only said that so I would agree to-"

"No. I do want this. This is what I've always wanted. I want to please you, Ise-san."

"You don't have to-"

"I want to."

Their eyes locked.

"Okay. But if you change your mind, you have to tell me."

"I will," she assured him.

Asia got on her knees on her seat. "Can I do it now?"

"Do what?"

She blushed. "Can I please suck your cock?"

"Y-"

[If I may.]

Ddraig. I'm in the middle of something.

[You should act like a real Master. That is what Asia wants.]

What am I doing wrong then?

[Let me give you some pointers.]

"No," Issei said. "You can't."

Asia frowned. "Ise-san?"

"I don't want you to suck it. I want you to worship it. I want you to choke on it. I want you to show me how much you want to please me. I want you to make me cum over and over and over, and I want you to swallow everything. I want you to remember the taste and learn to love it. Learn to crave it."

She fidgeted in her seat. "Master."

"What's wrong?" he reached out and touched her pussy. "Oh my, someone is getting in the mood."

"Please," she begged. "May I worship your cock?"

"Now you can."

She leaned down and licked his cock slowly.

Issei reached over and rubbed her pussy. She moaned around his cock.

Asia wrapped her lips around his cock and pushed it in slowly.

She could take it down about halfway before she started gagging.

Asia came up to breathe. "I'm sorry. I'm terrible at this. I shouldn't even be allowed to do this. You deserve way better."

"You can practice," he said. "Every day, until you do it better."

"You should let me practice on a toy until I do well enough to graduate to your cock."

"You're trying hard, that's good enough for me. Keep going."

"Yes, Sir." She took him back in and bobbed her head up and down.

He wasn't going to last very long.

"Fuck, go faster."

She did as he said.

Issei pushed two fingers inside her pussy. She sucked him even harder.

"Ah, fuck. I'm gonna cum."

"Inside," she begged. "Please."

Asia sucked him as fast as she could.

Issei orgasmed. She had a small orgasm herself when he came into her mouth. He could feel her pussy weakly contract. It wasn't a full orgasm though. He had seen Asia orgasm before, and this wasn't powerful enough.

Issei stopped rubbing her. He was really tired all of a sudden.

Asia gently coaxed out the last drops of cum with her hands.

Suddenly, Issei's left arm started glowing white.

What the hell?

[Your magic is restoring to its full power.]

Spikes appeared on his arm.

Ddraig, this isn't normal.

[Hm. That's weird.]

You think!?

"Ishe-san?" Asia looked confused. Her mouth was full of cum.

[You're evolving.]

"I'm what?"

[This happened before. You don't remember the Awakening of your gear? The Second Liberation during the Rating Game?]

Why now?

[Dragon are made to dominate. You've dominated Asia so you're dragonifying more.]

Is that a good thing?

[It is.]

But I've dominated Rias before, he argued. Why didn't this happen before?

[You felt some guilt about it. That held you back. This time it was consensual so there is no guilt.]

The glow subsided.

There were three red spikes on his arm now. When he focused, they retracted into his arm.

Issei tried a few times and found he could pull them out and retract them at will.

Asia hummed something. She looked at him with her big green eyes.

"Oh, sorry. You can go ahead and swallow."

She did as he asked. "Thank you, Master. What happened?"

"You don't need to worry. I just became stronger."

"Oh. Because of me?"

"Yes. Because you did so well." He patted her head.

Asia beamed at him. "Shall I do it again?"

[We're almost there.]

"Later."

He looked at the road. They had gone off the highway and were now driving on a dirt road in a dark forest.

"You better get dressed," he said. "We've arrived."

"Okay."

Issei put his cock away and helped Asia get dressed.

A bit later, the car parked itself.

They both got out. Their devil eyes quickly adjusted to the darkness.

Asia's mouth fell open.

They stood in front of a large stone building erected seemingly in the middle of the forest. It looked like a small caste.

A black steel fence surrounded it with a gate in front of them. The gate was closed with chains. Runes were engraved in them and they glowed faintly red.

"Where are we?" she asked.

"Red Dragon Emperor base," Issei said.

"What?"

"The previous wielders of the Boosted Gear build countless bases around the world. This is the closest one."

"How did you know where it was?" she asked.

"Ddraig was there when this was build."

Issei summoned his Boosted Gear and touched the chains.

The chains unwrapped themselves and the gate swung open. They recognised his Boosted Gear and responded to it.

"No one else should be able to enter," he explained. Unless they broke through the barriers.

"And the road here?" she asked.

"Invisible for anyone else."

"So we're safe here?"

"We should be. Come on."

Issei got back in the car with her.

They drove through the gate. Once they were through, it swung close again and the chains locked it in place.

Issei parked the car. They got out and went inside the house.

He turned on the lights in the hallway.

"There is electricity here?" Asia asked.

"Apparently they use some kind of solar panels. Advanced technology from Heaven."

"How did they get that?"

"Long story."

They walked through the hallway and went into the living room.

"Not bad," Asia said. "A bit dusty though."

"It's been out of use for a while."

They continued to the kitchen.

Issei opened the fridge. The light didn't go on. "Hm."

"Maybe you should put in the plug?" Asia suggested.

"Great idea."

He plugged it in. The light turned on.

"There we go." It was still working even though it was quite old.

He closed the fridge again.

They continued exploring. The castle was pretty big, so they didn't go through all of it right away. But they found the bathroom and…

"This must be the master bedroom," Asia said.

There was a large four-poster bed that could fit at least ten people. It had red drapes around it. Above the bedhead was a wall painting of two fighting dragons, a red one and a white one. The red one was clearly winning.

She sat down on the large bed. A cloud of dust rose.

"This house needs a proper cleaning," Asia said.

"That can wait until tomorrow. I've got some sleep to catch up on."

"True. Let's unpack and go to bed."

"Yeah."

They unloaded the car. He put the food away in the kitchen and brought his clothes up to the bedroom.

"Uhm, Master?" Asia asked. She fidgeted.

"You can just call me Ise like before," he said.

"No, no, I should address you properly."

"Your call."

"Anyway, what should I do with this?" She held up the cage.

"Give me that."

She handed it to him.

Issei held it in his left hand and made a fist. The spikes appeared.

With a crunching sound, the cage was reduced to a ball of metal.

Interesting.

[Like I said, dragon powers.]

He dropped it on the floor. "Let's go to bed."

"Hold on one sec."

Asia opened a window and fanned their blankets outside to get rid of some dust.

Issei stripped down to his underwear. He didn't bother with his clothes and just threw them on the floor.

Asia finished with the blankets. She left the window open and returned to him.

"Uhm. Should I sleep here? It's no so appropriate for-"

"Asia, you're sleeping with me, obviously."

"Okay. I'll get changed then."

He looked away while she changed. Not to give her privacy, but because she clearly wanted to surprise him.

"What do you think?" Asia asked.

He looked up. She wore a very translucent green nightgown without a bra and delicate lace panties in the same color.

"You look good."

"Thanks. I picked it out just for you."

"When did you do that?"

"A while ago," she said. "But I never dared to actually put it on. But now, well…"

"I see. Come here."

She came in bed with him.

Asia put her head down on his chest and he wrapped his arm around her.

It was silent for a while. Issei was drifting off to sleep when she suddenly spoke.

"I uhm… I'll start tomorrow on my chest, if that's okay with you."

"Huh?"

"I wasn't kidding before," Asia said. "I'm gonna use magic to make my chest grow."

"You really don't have to do that for me. You're fine the way you are."

"I want to do this," she said. "I really do."

"It will hurt," he warned her.

"That's just proof of how much I love you. I can handle pain, Master. Please let me do this for you."

"Can you relieve some pain using your Twilight Healing?" he asked.

"I think I can," she said.

"Alright. Then you can do it. If you help yourself with your Sacred Gear."

"That's really not nec-"

"I'm sorry did I make myself unclear?" he said. "That was an order, Asia, not a question. You're gonna relief the pain, whether you like it or not."

"Yes, Master."

It was silent for a while.

"Thanks," Asia said.

Issei didn't reply. He had already fallen asleep.
