For a moment Erza thought Kagura was going to resist, which would've made things a lot worse for both of them. Fortunately, she didn't. As the Mermaid Heel mage walked towards her, the redhead tried to decide whether to let the girl keep her pants on or expose her bottom. Given that Kagura was not used to getting spanked, perhaps forcing her to lower her pants on top of that would be a little too much, but Erza decided it would make things easier for the two of them in the long run if they took that out of the way as well.

"I want to make something very clear with you, Kagura" The Fairy Tail mage said sternly in response to what she'd just heard. "I'm never going to threaten you with early bedtimes or spankings. I will spank you and I will ground you if you act up. That's not a threat, and it's not up for negotiation either. And don't think I see you as less of an adult because of that."

"Anyway..." When Kagura got close enough, Erza reached for her waist. It was pretty obvious what she intended to do: her hands raised the hem of Kagura's skirt and grabbed the waistband of the black tights under it, preparing to pull them down. "It's about time to get this over with."

Kagura read a lot of material last night about sisters. One of the books talked a lot about how the older sister usually took charge of discipline and usually dictated obedience most of their life even as adults. Kagura not having a big brother for years had to adapt to someone telling her what to do again. She enjoyed it to some extent because she didn’t have to be completely responsible and someone held her accountable. On the other hand all the rules and threat of punishment made her nervous.

Kagura just groaned loudly when Erza explained how punishments would work. It seemed Erza decided a punishment and when she did Kagura would receive it whether she wanted to or not. “But…. Erza-nee I know I’m your ‘little sister’, but I’m not Wendy’s age,” Kagura said. The girl had no excuse she just didn’t want the embarrassment.

Kagura blushed when Erza went to bare her bottom. Out of instinct Kagura smacked Erza’s hands way or tried to. “W-wait you can’t just take my clothes off. I know you always spank bare, but look I’ll take the early bedtimes choice I don’t want a spanking anymore,” Kagura whined. Erza’s stern attitude really made Kagura want to escape this punishment.

Although she did expect Kagura to try and resist having her bottom bared, it did not make Erza any less angry. When the girl attempted to smack her hands away -- to little avail, might one add --, the redhead glared at her and landed a powerful smack on her left buttock, which sent a thunderous SMACK! echoing through the room. "Listen carefully, Kagura. That choice is no longer available and things will be much worse for you if you keep resisting. You are going to get spanked, and your pants are coming down. That's decided. Now quiet."

When the Fairy Queen resumed taking Kagura's tights down, she did so much more vigorously than before, making sure even her so-called sister could not escape. Angry at the girl's defiance, Erza did not even hesitate as her hands grabbed the waistbands of both Kagura's black tights and the underwear beneath, then tugged them down to her knees in a single motion. It was clear the redhead meant business, there was no convincing her otherwise now.

Erza didn't even give her much time to feel ashamed - as soon as her bottom was exposed, the Fairy Tail mage immediately grabbed Kagura's wrist and flipped the girl face down across her knees. She did not intend to use anything other than her hand for this spanking. It was Kagura's first time and the offense was not that serious either, but from that previous smack alone the Mermaid Heel mage would know she was not going to sit comfortably for a few days.

Kagura didn’t know what to expect from Erza when she attempted to smack her hands. However, she wasn’t surprised by the hard smack, but it still caught her off guard. She knew Erza was strong, but this hurt like hell. Kagura yelled loudly and just stood there in shock. If that was one smack Kagura would certainly sob by the end of this punishment. She had seen Natsu take a belt from Erza how the hell did he handle that if she just used her hand.

Kagura squirmed when her bottom quickly became bare. “Wait, don’t eek,” Kagura said. She tried to move her hands to cover her bottom, but she failed. Erza had pinned them, so she had no choice, but to stand there bare bottomed.

Unfortunately the girl didn’t have time to be embarrassed, which was bad considering embarrassment felt better than pain. The girl would not physically resist anymore, but this would not stop her from whining. She didn’t sign up to be spanked like a little girl just by being a little sister. “Erza I did not agree to be treated like a little girl by becoming your sister. Let me up,” Kagura said.

"Sorry, but I don't think you not agreeing with it is that much of a problem. You see, it wouldn't be a very effective punishment if you could decide whether to take it or not. As my sister, you are under my rules, and I don't really care whatever else you have to say on that subject" Once Kagura was firmly placed over her lap, Erza took her time to address what she'd just said. The Titania did not start immediately. Instead, she let her sister process everything; she was laying face down over Erza's lap, her tights and panties around her knees, bare bottom ready to be punished.

As if to emphasize the situation, the redhead grabbed the hem of Kagura's skirt and flipped it up, exposing every inch of skin on her butt. She then placed one of her hands right on the middle of her bottom and inhaled deeply before speaking again. "Kagura, you already know why you are going to be punished. I don't mind you staying up late at all, but I do mind you staying up late when that results in you showing up late for a mission the next morning, missing a train, then trying to go on said mission without proper rest, and I definitely do mind you showing me attitude when I try to address it! When I tell you to do something, I expect you to obey. Got it? Good"

Erza did not know how Kagura would react to being lectured again, but she did not wait for it either. As soon as she said 'good', the redhead raised her hand and brought it down on the girl's right cheek; not long after a red handprint appeared on the pale flesh, just like the one on the left side. Unlike before, this time Erza did not stop at one, and immediately followed up with two other slaps, all of them aimed for the exact same spot. SMACK! SMACK! SMACK!

Kagura didn’t like this one bit. She didn’t expect the sister relationship to end with her having to follow Erza’s rules. It didn’t matter what she thought apparently though at least when she acted naughty. The young woman just had to deal with the consequences of her actions when she acted up losing all day. It felt strange she had never been spanked well not since her bother a long time ago. The sensation was nice despite the embarrassment. It showed how much Erza cared about her after all she only did this with her Fairy Tail members, which she considered family.

Kagura wanted to argue, but she couldn’t really. Everything Erza said was true about her being late. She deserved a punishment for wasting Erza’s time and putting her self at risk by going on an S class mission without enough rest. However, she didn’t think that obeying was something she had to do if she didn’t want to. “Wait….. I shouldn’t have to obey. What if it’s owwww un… ekkkkk owww. Shit owww Erza-neee,” Kagura whined.

Kagura kicked her legs in pain as her bottom was assaulted. The fact that the same spot got hit increased the pain a lot. “Owwww it hurts,” Kagura whined. “Spank somewhere else,” The girl added. She wanted to have some say in this still. Being the leader of her own guild made her want to be in charge.

"As I said, you don't really have much of a say on that. You can either be a good girl and obey or get your butt spanked by me every time you don't" As before, Erza went for a very direct approach. She was not hiding anything from Kagura, and hoped the girl would eventually realise who was in charge there. If not, that wouldn't be the last spanking she received from her big sister. Unbothered by Kagura's request, the redhead kept smacking the same spot repeatedly. SMACK! SMACK! SMACK! SMACK!... four more landed on the right cheek, for a total sum of seven, when Erza finally changed her target.

Now was time for the left buttock to suffer under her palm. There was no warning before it landed on the exact same place she'd smacked Kagura when the girl was still standing. Before the sting could fully sink, a second one came down, then a third, and a fourth, all rapidly landing on the trail of the first one. As the spanking progressed, the gap between each slap became much shorter.

Of course, there was a reason for Erza to be doing that. By now she had enough experience spanking her colleagues to understand it was better to warm each cheek up individually before starting to alternate between them, although it didn't make things any easier for Kagura considering it was her backside getting slapped. When the seventh smack landed on the left side of her bottom, Erza alternated again - and seven more would soon be targetting the right cheek again. "Am I getting through to you now?"

Kagura knew this was about her staying up late and missing the train, but this also involved a power struggle. Kagura had to admit to herself Erza now had power over her at least when it came to her behavior and the consequences. Kagura could make her own choices, but now they had consequences. The master of Mermaid Heel over Erza Scarlet’s knee felt pathetic, but also Erza was the strongest woman in Fairy Tail. Kagura said nothing this time as she had no time.

Kagura couldn’t speak between the swats now. She had not been spanked in a long time, so she had no tolerance for it. The girl could take pain in battle, but this was different. Her bottom was vulnerable to Erza and she couldn’t stop it no matter what well… unless she used magic. However, Kagura knew that would be stupid. Erza would be pissed if she tried that.

The girl just laid there letting out yelps. “Yes I get it Erza-née. You’re in charge of me,” Kagura finally said giving up her power.

Although she was satisfied to hear Kagura had finally given up, Erza did not stop or slow down at all. This was still punishment! Her firm palm continued to rise and fall in rapid succession, and every time it did, another loud SMACK! echoed throughout the room. However, now she finally decided to start alternating. Perhaps Kagura would think of that as a relief at first, but by now her buttocks had been punished enough that every smack would leave a sharp sting and a horrible burn afterwards.

"That's more like it. Keep that in mind, behave and I'm sure you will not be over my knee that often. At least not nearly as often as my teammates. Unfortunately, right now we still have some talking to do here" As it went on, for the first time Erza aimed for the lower curve of Kagura's behind, right at the sitting spot. SMACK! It was a single slap, but the strength applied and the sensitiveness of the targeted area probably would be enough to deliver the right message. Luckily for Kagura, the Fairy Tail mage went back to targetting the upper cheeks afterwards.

... SMACK! SMACK! SMACK! SMACK!... With little time between every slap, they landed very quickly. Erza's hand alternated between the left and right sides, and sometimes the center, making sure no inch of her flesh was spared. Every now and then Erza would slow down just a bit to look at her work. She didn't want to overdo it, of course.

Kagura had given in, but it didn’t make the punishment any easier to take. It only made things harder because all she could do now was with stand. It was hard for Kagura to understand she had no say on how hard this went or for how long. Erza controlled this completely and it seemed like Erza planned to make this a memorable one. At least she would sleep on the train because all she wanted was to be back in bed. She certainly wanted to be anywhere, but getting her fanny whooped.

Kagura thought it would take quite a while after all. She wasn’t a weak mage by any sense. She wasn’t too far behind Erza, but this spanking and the way she punished. Kagura already had a tear or two running down. Her lack of spanking endurance and Erza’s expertise had the girl in tears. The alternation felt much worse now that both of her cheeks were sore. It may not have been the same spot each time, but now that they were sore it certainly hurt.

“Owwww. Owwww I’m s-sorry Erza. I’ll behave I promise,” Kagura said. She certainly would think twice about messing around with her older sister the whole train ride to the S class. The girl would probably try to stand the whole way.
