"Decency woman!"

Naruto was shouting loud enough to wake up other people in the building, the apartment building that everyone in Rias' peerage lived at, other than Issei and Asia. Naruto was staying there as well, because while he was not part of the peerage, he and Rias were dating. He was pretty sure they were dating, but that didn't excuse the fact that Rias had stepped over the line.

"... surprise?"

"Surprise, I almost had a damn heart attack when I woke up!"

"I like to sleep naked though."

"IN MY BED!?"

The root of the issue was that Rias had snuck into his bed, completely and utterly without a shred of clothes on her body. Naruto didn't wake up when she got into his bed since there was no danger, and he didn't wake up when she pressed herself up against him and hugged him all night. He didn't wake up through any of it, he woke up in the morning feeling surprisingly refreshed. It was a great night of sleep, and he was sure having a woman by his side helped his sleep.

Waking UP to a woman by his side didn't help his heart.

*THUMP*

"Ow..." Rias held the top of her head where he popped her with his knuckles. Her eyes watered from the hit, even if it wasn't hard enough to really hurt her. She hadn't expected him to be angry when he woke up. She wanted to be seductive, she had hoped to give him a shock.

Rias' Imagination

"Hello love, lets stay in bed."

She had hoped to wake up before him, and she did wake up before him, but the second his eyes opened he launched her across the room like a spring. He screamed in shock and grabbed a knife under his pillow, something she didn't know was there. She was glad that he didn't accidentally stab her in his sleep, she would need to take extra care to get rid of the knife next time. Of course, he calmed down a lot when he realized that it was her that snuck into his bed, naked.

"Naked Rias!? You can show a little seductive cleavage, after 3 dates you can kiss, and then after 5 or 6 dates you can go further with petting. There is an order to these things, you don't go for the bedroom until like the 8th date... unless you plan to make it a one night stand... are you stupid in the head." Naruto pushed the top of his finger into the spot on her head that he knocked. He had forced her to sit on her knees to repent for her giving him a heart attack.

He could have killed her for scaring him like that.

"I wanted to give you a pleasant surprise... and maybe we could have-"

"My feelings Rias! You have to consider how your partner will feel about you sneaking into their bed, stripping yourself butt naked, and hugging them. That is literally sexual assault what you did!" Naruto reminded her just how serious what she did was. If he had been most people, maybe not most guys, but Rias would have been in a lot of trouble. Rias was hot so she could get away with a lot, but if nearly anyone else had done what she had done, they would be punished for it.

Either by the law, or by a beating.

"Ah... if it makes you feel better, you can do something naughty to me-" Rias started to get super seductive, her body language changed.

*BONK*

"OW!?"

"I'm not done shouting at you for what you did yet, so don't try to seduce your way out of this!"

"Ow!?" Rias got another bonk, and she held her head with both hands, looking up at Naruto with confused eyes. When she revivied Issei as a devil he was super excited when he woke up next to her naked, she needed to be nude to best heal his injuries at the time. She would have expected Naruto to have a similar reaction, seeing as he was a pervert like Issei to some degree. She was surprised when it seemed that Naruto's strong sense of moral fiber seemed to be a stronger defining character trait.

Then again, she did sneak into his bed naked, but Issei was weird in that his reaction to waking up next to a naked stranger was different than the should-be reaction. Maybe it was Naruto that was having the normal reaction.

"Hey Naruto, I've got something you might like to see-"

Sirzechs stopped what he was doing when he walked into Naruto's bedroom and saw Rias butt naked, on the floor, with her head in front of where Naruto's crotch was. He raised an eyebrow and looked carefully to see that Rias was not giving Naruto a blowjob.

He did send Naruto a thumbs up.

"Nice-"

"Rias snuck into my bed butt naked, and now I'm lecturing her about proper scaring me." Naruto deadpanned when he saw that expression of approval.

"Ah... sleeping naked is a bad habit she got from mother."

*BONK*

"Have a normal reaction to hearing that your sister was caught butt naked in a man's bed!" Naruto bonked Sirzechs on the head, and put him right next to his sister on the floor. "You're suppose to be furious and protective."

Rias and Sirzechs were right next to each other, and they exchanged glances.

"Aren't ninja... masters of seduction."

"You're a good guy, I'm sure you would take care of Rias if anything happened, and she's a big girl who can make her own choices about men." Sirzechs pointed out. He was old enough to know that getting overprotective of Rias when it came to sexual matters was just stupid. They were devils, they were a sexually open people.

Rias was just shocked a ninja was giving devils lectures about morals.

Naruto sighed.

"Yes, but most ninja don't live their lives always being seductive or sexual. What we do for missions and what we do at home aren't the same thing... and usually people don't survive having sex with a ninja." Naruto walked over to the bed, and he lifted up his pillow to show several more knives were laying there.

Sirzechs looked at Rias.

"... Next time you do this, make sure to get rid of those."

"I plan to."

"Don't agree with each other!?"

*DOUBLE BONK*

"OW!?" Sirzechs and Rias shouted when they both got chakra enhanced bonks to their heads, and this time it was hard enough to form lumps where his fists connected. Rias raised her hand up, as if she were going to ask a question.

"... So this would be okay if I didn't start out naked, and I didn't sneak into your bed?"

"Yeah, that would be fine." Naruto relented that what she asked was acceptable. As long as she wasn't naked, and didn't give him a heart attack when he woke up by surprising him, then he would be fine with her in his head. It was the sneaky act of slyly slipping into his bed that he found heart pounding.

'Then I'll just wait for him to fall asleep before stripping-'

*BONK*

"I can't read minds, but I can read faces and guess what you're thinking. I bet you were thinking you would wait for me to fall asleep, before stripping... if you ever come into my bed dressed, and I wake up to you naked... I'm spanking you." Naruto said with complete seriousness.

'Sounds sexy.' Sirzechs thought.

'Sounds sexy, I want it.' Rias thought as she made plans to do that very thing the next chance that she got. 'I can use this to seduce him into ravishing my body.'

*DOUBLE BONK*

-Next Day-

"OW!"

Rias didn't like getting spanked when Naruto covered his hands in chakra, it hurt a lot more than she thought it would, and he didn't pull her panties down to make it sexier. Instead he made her wear pants while he spanked her.

"934"

"OW!" Rias shouted, at first her moans at getting spanked sounded sexual, but now they were just filled with pain and regret. She had thought, assumed, that Naruto would be perverted about her spanking. No, instead he was making sure every smack to her buttcheeks caused as much pain as he could cause. He made sure to avoid going near her vagina like the plague when he did it, he got her at the most painful and least pleasurable parts of her ass with each and every spank.

Apparently Grayia had told Naruto about the Gremory family 1000 spanking policy, about how when a servant would act up they would get magically spanked 1000 times.

So this was how that felt.

Why make her wear pants though?

Rias learned why Naruto made her wear pants very soon.

"Ow... ow... ow..." Rias, when she got all 100 spanks, learned that her butt was red and swollen. Removing the tight pants from her bottom was painful, and it rubbed up against her swollen booty. "This wasn't sexy..."

"I don't know, it was sexy for me... maybe we should do this every morning."

"Lets not." Rias was not going to be taking her clothes off in his bed while he was asleep. She would wait until the day that Naruto said she could sleep naked in his bed, and until then she would be satisfied with that.

"Oh, what's wrong Rias, those pants are coming off pretty slow, let me help you."

"EEEEEP!" Rias jumped and put her hands on her butt in pain when he just quickly pulled the pants she was wearing down.

Akeno walked into the room.

'... I want that...' Akeno licked her lips when she saw Rias rolling across the floor, making sure to never let her butt touched the carpet when she did so. She could see just how red and swollen those cheeks were, and she wanted to experience that for herself. "... breakfast and tea are ready." Akeno passed the message along.

She had cooked it herself.

*BONK*

"You're the Queen of her peerage, it's your job to keep your Master from doing this. Do you job Queen girl, and make sure that Rias stops acting like a cheap whore-"

"I'm your cheap whore though."

"THAT ISN'T A COMPLIMENT!"

"I'll do anything you want though, you just have to ask." Rias knew that made her seem like a whore, but this was her happy ending. She didn't mind if Naruto ravished her body or unleashed his desires. She was perfectly fine with it, she encouraged it even.

Akeno pushed herself up against Naruto.

"HEY!"

"If she won't do, then maybe-eh?" Akeno realized moments later that Naruto wrapped his arms around her, and lifted her off of the ground. Her back started to bend as he twisted her body using his own. "Ow... ow... owowowowowow... this hurts... hehehhe... OW...!"

"Ah..." Rias watched as Akeno's seductive nature turned his wrath towards her.

Good, gave her ass a chance to not get spanked.

"Are you... getting wet from this...?" Naruto looked at the wetness that dripped down Akeno's thighs, and he released his hold on her. He stepped away from her, but she turned around and sent him a seductive look.

"Why did you stop, I was just getting into it."

"She's a Sadist AND a Masochist." Rias informed Naruto of Akeno's unique situation. She enjoyed pain and other's pain equally. Naruto looked at Akeno with deadpan eyes, before stepped backyards from Akeno.

"What... is wrong with women in this era?"

Seriously.

Was there a non-perverted girl he could hang out with!?
