Issei woke up with a crushing headache.

What the hell happened last night?

[I'm not sure,] Ddraig said.

What do you mean 'you're not sure'?

[My consciousness is tied to yours. If you black out, so do I.]

Black out?

Oh wait, I drank alcohol last night, didn't I? With Akeno. Wait, where is she?

[I would guess at school. Given the hour.]

Crap, I'm late.

Issei quickly ate breakfast. He brought some up for Rias as well.

"Master." Her eyes lit up.

"Sorry. No time now. I'll play with you tonight, okay?"

"Okay." She mumbled.

He put her food down and hurried to school.

Issei texted Akeno.

[My memories of last night are a bit vague.]

[You drank way too much for your first time,] Akeno texted back.

[Do you remember what happened?]

[Why don't you come to the clubroom after school? I'll tell you in great detail. Maybe we can do some things over?]

[Okay.]

Why couldn't he remember these wonderful memories?

When school was finally over, he went to the clubroom. He had a vague feeling something was off.

Shrugging, he opened the door.

"Hey, Ake-"

What the hell?

The door slammed close behind him and a barrier went up.

He looked at the desk. "R-Rias. You're back?"

"Hey, Issei." She smiled. Her eyes were back to normal and her collar was nowhere to be seen. Akeno stood next to her in a leather outfit and, Issei swallowed hard, a whip.

[This doesn't look good,] Ddraig commented.

"That's impossible," he said. "This morning I-"

"Illusion spell," Rias said calmly. "You'd have noticed if you actually paid attention to your slave."

"B-But…"

Just what had happened last night?

[I think they found out,] Ddraig said. [Akeno must have put something in your drink.]

You think!?

"H-How did you…"

"I spied on you," Akeno explained. "I didn't want to miss Rias losing her virginity."

"Y-You-"

"I didn't expect something like that. You were amazing, Issei. I came three times watching you."

"But, you-" if she had enjoyed it so much, then why…

"If you had willingly enslaved her I would have been fine with it," Akeno said. "But you didn't. So I had to free her."

"How did you know how to free her?" he asked.

"Asia spilled the beans on your little spell."

"She betrayed me?" He couldn't believe that. Asia would never betray him.

"I had to give her a little… encouragement ." Akeno played with her whip.

"You little-"

The whip hit his face. An angry red welt appeared on his cheek. It hurt badly. That wasn't a normal whip.

"Fuck."

"Enough talking," Rias said. "Get on with it, Akeno."

His eyes darted around the room. There were no escape routes. There was a strong barrier on both the door and the windows.

Maybe he could overwhelm them?

However, Akeno seemed to have sensed his intentions. She aimed her free hand at him and fired a lightning beam.

Issei was thrown backward and hit the back wall hard.

Stars danced in front of his vision.

He vaguely sensed Akeno forcing him up.

Then, he felt cold steel on his wrists. Handcuffs.

"Take a guess which handcuffs these are," Akeno teased him.

"You bitch."

He was slapped across his face.

Akeno calmly shackled both his hands together and attached a rope to the cuffs.

The rope went up to a hook in the ceiling.

She pulled hard. Issei was forced on his tiptoes.

[I don't think you'll get a normal spanking this time.]

Shut up. This is all your fault.

[ My fault? I warned you. I fucking warned you. But did you listen? No, because Harem King Issei knows better. How could you not notice Akeno was spying on you?]

I was rather busy. You-

"Let's begin," Akeno said. "Be a good boy and count them for me, will you?"

"What?"

The whip hit his chest.

Issei screamed. "Fuck. One."

She hit him again.

"Argh, two."

His shirt was quickly torn to shreds by her whip.

While she didn't whip him hard enough to draw blood, he was certain she used magic to increase the pain. His devil body should be sturdier than this.

"Twenty," he grunted. By now, his legs had given way and his wrists held his full weight.

"Hm, you think he has learned his lesson?" Akeno asked Rias.

"Please, no more," Issei pleaded. "I'm sorry."

He'd need his strength in case there came an opportunity to escape.

"Hm. I think this is enough," Rias said. "For now."

Issei let out his breath.

Akeno released the rope. He dropped down on his knees right away.

"Get up," Akeno ordered.

He stood up on shaking legs. He considered attacking her, but that would probably feel. He needed a better opportunity than this. Maybe if they were satisfied he could-

"Now," Rias said. "To make sure you behave yourself in the future, I got you a little present."

She took something from her drawer. It was some kind of metal…

His breath stopped.

"What the hell is that?" That thing frightened him way more than Akeno's whip.

[Looks like a cock cage to me,] Ddraig said calmly.

I know what it is!

[Then why did you ask?]

Any hope of getting out of this quickly sank.

"Kiba has one too," Rias said with a smile. "Why do you think he turns down all those girls? He's our chaste little Knight-boy."

"Well he did ask for it himself," Akeno pointed out. "Eventually."

"That's true. But I think Issei wants it as well. Isn't that right?"

"What?"

He didn't even want to be in the same room as that thing.

"I think he needs another taste of your whip," Rias said to Akeno.

The Queen raised her whip again.

"No, no," he quickly said. "I want it."

They were gonna put it on him anyway, so he better play along.

"Well beg for it then," Rias ordered him.

"Uhm…"

How the fuck do I do that?

[Repeat after me,] Ddraig assisted him.

"W-Will you please put that thing on me?" Issei asked.

"That's not begging," Rias said. "Akeno."

"Wait-"

He got three hard lashes on his chest.

"Beg for it properly," Rias told him.

Issei knelt down in front of her. "Please Mistress. L-Lock up my worthless cock."

Luckily, she didn't know he was just repeating what Ddraig told him.

"Now we're getting somewhere," Rias said. She reached out with her foot and rubbed his cock. Her socks felt really weird. "You want the cage?"

"Yes please. I need to be locked up. I can't be trusted."

"But then how will you please us?"

"I-I don't know."

"Guess we'll have to teach you to use your tongue," Rias suggested.

"Yes, Mistress. Please teach me."

"Stand up."

He did as she said.

She rubbed his cock. "Oh my, you're getting hard. Is this so exciting to you?"

Issei said nothing. His body was responding involuntarily.

"We can't put it on when it's hard."

"If I cum it will-"

Rias laughed. "Don't be silly. I'll get it down." She slapped his cock.

"Argh… fuck."

"You need to learn how to control yourself," she said. "I didn't give you permission to get hard." She slapped his cock again.

"I can't help it," he said between gritted teeth.

"Oh, you'll learn."

Another slap.

His erection went down.

"There we go."

Rias carefully put on the metal cock cage. The set of metal rings fit snugly around him. She attached a small padlock at the base.

Please don't.

The lock closed.

He was helpless now. The cage wouldn't even allow him to get hard.

His King put the small key around her neck, right between her breasts.

The cage glowed purple for a moment.

Magic. It wouldn't come off without the key, no matter how much he tried forcing it.

Maybe he could use-

[Forget it. Don't you sense it?]

Sense what?

[If you use magic to force it open, the spell will activate and… well, I'll spare you the details.]

What?

"Back on your knees, bitch-boy," Rias ordered. "Time for your oral training."
