XII. Rules of Play

On Saturday, Celester woke up at dawn. She would have slept in if it were up to her, but unfortunately her bladder had different plans. As she turned over, to get out of bed, the unicorn noticed her waist was snuggly hugged by an overnight diaper. She then remembered Stella had pleaded with her to wear a diaper, "because she likes when Mommy is padded as well".

Celester liked wearing diapers, especially on nights where she could sleep in, but rarely actually wore them. Except for when she was in heat, but that did not count, according to the unicorn. She turned on her back and tried to find a comfortable position to use her diaper. However, she was by far not as experienced in wetting herself while laying down as Stella was. After a few unsuccessful attempts, her tossing and turning woke the pony up.

'Mwommy? Waf you doin'?' she asked sleepily.

'I have to pee, but I can't seem to get started.'

Stella took her pacifier out and scooted closer to Celester.

'Well, I know the perfect solution for that,' she said with a sly grin.

'Wait, why do I feel like-' was all she could utter. In a quick move, Stella had positioned herself on top of Celester and began mercilessly tickling the unicorn. Celester managed to keep the pony at bay just long enough to put a Beacon of Silence in place, so their noise would not wake Rowan up. Despite being both smaller and lighter, Stella had her mate effectively pinned down. The girls could not hear each other laugh, but they could still feel the vibrations in each other's chests.

After a few minutes, Celester's facial expression suddenly changed. A few seconds later, the sound returned.

'What's up?' Stella whispered between huffs.

'What do you think, filly?'

'I just made you wet yourself, like I said I would?'

'Is a certain little pony going to be cheeky?' Celester said, pretending to be mad.

'Phht. It's not as if you hate it. Besides, it'd be a shame to take off a diaper that is still dry.'

'True, but I only like it because it's our special secret. You know what else is a shame?'

'Um, no?'

'Letting the warmth of a freshly wet diaper go to waste.'

Stella felt her heart beat faster, in excitement for what she knew was about to happen.

'It'd be better if you take the wetting alarm out,' Celester instructed as she opened the bottom drawer of her nightstand.

The pony nodded and quickly left for the bathroom. She returned a minute or two later. By now, Celester had folded the covers back. She was sitting on her bottom, in the middle of the mattress. In her hands was a large pink wand vibrator, that was plugged into a nearby outlet. Stella's heart fluttered as she saw her favorite mare holding one of her favorite objects.

'You wet in your sleep again last night,' Celester whispered seductively. 'And you know what little fillies get when they're good.'

'A reward?' Stella answered with feigned ignorance.

'Come over here, you goof,' Celester laughed.

Stella climbed onto the bed. Her heavy overnight diaper crinkled softly as she reached to embrace the unicorn. She felt her onesie press the squishy dampness of her nighttime accident against her princess parts, between her legs, and against her bottom.

'I love you, Cel. All I could wish for.'

'I love you too, dear. My favorite pony.'

Stella giggled shyly.

'I'll put a Beacon of Silence on the wand, so we can do our thing without having to worry about waking Rowan up.'

The pony nodded. Celester concentrated for a few seconds, after which the wand was covered in a faint glow. Stella scooted closer, until the fronts of their diapers almost touched each other. She put her legs over Celester's thighs and crossed them behind the unicorn's back, careful not to pinch her tail.

_ Ready?_ Celester mouthed.

Stella nodded and was handed the wand, which she carefully positioned with the large head between their diapers. Celester embraced her with both arms under her armpits, letting her hands rest in Stella's shoulder blades. The girls could sense each other's arousal even more now their chests were touching and they could feel each other's breathing.

The mares nuzzled as Stella switched the wand on. While the nuzzling turned into kissing, she gradually increased the intensity of the wand. Celester usually had her eyes closed during sex, so she could fully focus on the bodily sensations. Stella, however, loved to watch her beautiful unicorn wife enjoy herself.

Shortly after she had increased the speed of the wand a third time, she noticed Celester's horn lit up in a soft icy blue glow. The girls were lifted up, until they were floating a few inches above the bed. Stella knew this meant Celester was exceptionally aroused, as this only happened when she was enjoying herself even more than she usually did.

The combination of the feeling of weightlessness, the vibrating wand massaging her princess parts through the wet padding of her diaper, and Celester bucking her hips became almost too much for the pony. She then remembered Celester was so attuned to her feelings, having an orgasm of her own usually sent the unicorn over the edge as well.

Moments later, an explosion of pleasure erupted from the most sensitive part of her body, traveling like electric high-speed dominoes through her entire body. As her orgasm began to ebb away, she felt Celester's legs contract and her back arch. If it were not for the Beacon of Silence, the unicorn's cry of pleasure would probably be audible in the entire house. Stella slowly opened her eyes and noticed they were now a foot or two above the bed. She was just in time to see Celester experience the height of her orgasm.

The telepathic attunement worked in both ways, however. The sensation of Celester's orgasm overflowed to Stella, both physically and emotionally. Realizing she had made her wife cum so intensely they were still floating quickly brought Stella close to orgasm again. She increased the intensity of the wand one more time, which almost immediately made her orgasm for the second time that morning.

Once both mares had finished their orgasms, they gently landed in the bed. Celester felt her back touch the mattress, and Stella ended up laying on top of her, hugging and kissing her. Just as Stella wanted to sit up to switch the wand off, Celester grabbed her by the bottom and firmly pushed the pony's hips down. This of course increased the intensity and the depth of the vibration they both felt, which soon pushed Celester over the edge a second time.

When she estimated the unicorn had rode out her orgasm, Stella switched the wand off. She laid down on her back, as close to Celester as possible, and gently stroked her hooves with her own. She grabbed Annie and absentmindedly petted the soft plush. Suddenly, she heard herself breathe heavily. It took a moment before she realized Celester had deactivated her Beacon of Silence.

'Thanks for the stellar time, dear. You're my beautiful pony.'

'You're welcome, princess.'

Stella tried to suppress a giggle, but with little success.

'What's so funny?' Celester laughed.

'I told you I'd get away with making you wet yourself.'

'So that's why you insisted on diapering me last night.'

'May-be,' Stella said innocently, drawing out the syllables.

Celester playfully elbowed the pony. 'If I get to have two amazing orgasms in return, so be it.'

Stella shyly hid the bottom half of her face behind Annie.

'Aww, you're so cute. Do you want me to change you already?'

The pony shook her head. 'I have to pee, but I need a minute.'

'That's okay. I'm going to take a shower. I'll put you in a clean diaper when I get back, okay?'

Stella put her pacifier back in her mouth.

'Ish okay's, mwommy.'

When Celester returned from her shower, brushing her still-damp mane, her attention was caught in the hallway. She heard the familiar noise of a crinkling diaper, but it sounded way too... rhythmical. Her first thought was that Stella was getting carried away with enjoying the feeling of her wet diaper, but then she realized they had just had sex. And they had both had not one, but two powerful orgasms.

No, it would be strange if Stella would still have any energy left to play with herself. Furthermore, if she still desired more playtime, she would have asked for it before Celester went to take a shower. That left only one other option. She perked up her ears and listened closely, which soon confirmed her second guess. The sounds were coming from a different bedroom.

Rowan had woken up from the sounds of the water hitting the shower floor. His attention was quickly caught by the feeling of his morning erection straining against the squishy padding of his diaper. He then remembered he had woken up in the middle of the night, disoriented, with a strong urge to pee. He had gotten up, out of bed, only to feel the thick padding of his new overnight diaper between his thighs.

It did not take long for him to get back in bed, under the covers, and snuggling up to his polar bear friend. Actually getting the flow going and wetting his diaper while laying on his back proved a lot harder, but eventually, he managed to relieve himself. With his diaper freshly warmed up and thicker than before, he fell asleep, feeling utterly safe and content.

Now, still warm under the covers, he idly stroked the soft plastic exterior of his diaper. He searched for his pacifier for a few seconds, then remembered he had taken it out and put it on his nightstand before he fell asleep. He did not dislike the pacifier, but it was a new experience for him. One that drew too much attention to fall asleep to.

On the topic of drawing attention, the straining feeling in his diaper slowly increased. Without fully realizing, he had begun to rub ever more intensely. He was so focused on the feeling of the soft squishy padding against his bits, that he did not notice the rather loud crinkling the rubbing produced.

Man, this feels good, he thought. I wish I had known about this years ago.

Not having touched himself for two years had increased both his sensitivity and eagerness. He rubbed the smooth plastic outside of the diaper, feeling the warmth of his morning wetting. As the tension built, he quickly neared his orgasm. When he was only a few strokes away from the edge, Rowan was suddenly startled by the sound of someone clearing his throat behind him. He yelped and pulled his hands off his diaper, keeping them close to his chest.

'Enjoying yourself?' Celester's voice sounded.

He slowly turned around and saw the unicorn standing in the middle of his room, with one hand in her side.

'You do know it's naughty to play with yourself, don't you?' she said in a not-so-serious tone.

'How... how did you know I was... y'know...'

'Playing with yourself? Your diaper was crinkling so loudly I could hear you from the hallway.'

'Oh...' he responded softly, pausing for a few seconds. 'A-are you angry w-with me?'

'Angry? Nah, that would be unfair.'

Rowan sighed with relief.

'I _am_somewhat disappointed, however.'

'Huh? Why is that?'

Celester crouched down near his bed, so they were at eye level.

'In this house, little fillies aren't allowed to play with themselves.'

Rowan looked away.

'Given, example A,' Celester continued, gesturing at his diaper. 'That rule should probably be applied to little bunnies as well.'

'B-but... I didn't know! I mean, I didn't know you girls have a rule about that.'

'That's why I'm not angry.'

'Oh. You are disappointed, though. Why?'

'Because you didn't tell me about your needs...'

He cocked his head.

'... and you didn't ask for help?'

'Wait, what?'

'You're a member of our household, dear. Stella and I have each other when it comes to sexuality, but that doesn't mean your needs should be denied or ignored.'

'I'm so confused right now. Is this an invitation to a trio? Didn't we already agree that none of us even want that?'

Celester chuckled. 'No, of course not. It's just that you're an adult, you have a certain sexual need, and I happen to know more than one way to make someone orgasm.'

'Does any of those methods involve a strap-on, or anything else inserted in the butt?' Rowan blurted out, then quickly covered his mouth with both of his hands.

'Heavens, no,' Celester laughed. 'We don't like that either. Don't worry.'

She suddenly stopped laughing when she noticed Rowan was tightly clutching Nanuq to his stomach, staring at his paws. He was trembling, and breathing shakingly.

'Rowan? Are you okay?'

He shook his head, almost unnoticeably.

'Did I scare you?'

No response came. Celester calmly put her brush down on the nightstand and embraced him, gently caressing his back. She blinked her horn, hoping it would tell her more about what was going through his head.

'Did the mentioning of sex remind you of Azalea? I'm sorry, Rowan. I didn't mean to upset you.'

'It's not your fault,' he whispered. 'I mentioned the strap-on myself. She had one that was intimidatingly large. I had the feeling I would be walking awkwardly for a week should she ever have decided to put it up my butt.'

'But she never did, did she?' Celester asked, trying to remain calm.

'No, fortunately not. She did threaten to do so, more than once. Especially in the first few months. And then she began bringing other guys home, almost every week. Sometimes several guys over the course of the weekend.'

'That sounds horrible, dear. Nothing about that is okay. Stella and I will never threaten to do anything to you that you're not comfortable with, especially when it comes to sex.'

'But what about you girls? You do punish Stella when she is disobedient. How does that work?'

Celester let go of Rowan and sat down on the bed, next to him.

'Well, we have agreed upon rules, but also discussed punishments. She doesn't want me to spank her, and I'm not keen on doing that to her either, so that's never an option. We usually try to pick a punishment that fits the crime.'

'And if that's not possible?'

'Then I resort to my favorite punishment.'

She paused for a moment, during which Rowan tried to keep himself from cringing. He did not know what to expect, but he felt his heart beat in his chest. What secret did these girls have? Were they into some extreme form of bondage? Was that what Celester meant when she said Stella had tried to "get out of corner time"?

'Writing lines,' Celester said with a grin.

Rowan sighed in relief, then realized what he had just heard.

'Wait, lines? As in, with a pen, on paper, like teachers do?'

Celester nodded with a smile. 'It's quite a harmless punishment, but it's annoying as hell. I can make her write down whatever she shouldn't do and what I expect of a good filly. That, and she has to write the lines with her non-dominant hand. There's no room for rushing that way, because I'm allowed to disapprove of any lines that are written too poorly. A good filly is careful with her handwriting.'

'That makes sense. And I agree writing lines doesn't really hurt anyone, but it _is_time consuming.'

'Which is exactly what a little filly doesn't want when she's busy playing. As in actual playing, not playing with herself.'

Rowan grimaced.

'We do need to have a serious conversation, however,' Celester continued. 'Now that you're an official member of our household, we should discuss what rules apply to you.'

He tilted his head.

'Stella has to ask me for permission to play with herself. Even then, she doesn't get to touch her princess parts. Only I get to do that. She prefers it that way, even though she might not admit it.'

'B-but she's a filly. Isn't that, y'know... Wrong?'

'Having sex, you mean? Well, here's the thing. Stella plays filly. She still has the body of an adult, with the grown-up needs that come with it. For instance, there are slightly different rules when she's on her period, because that sometimes makes her not want to play filly. I enjoy our dynamic, but it's not why I married Stella. I'm madly in love with her because she's not a boring person, and mostly because she dares to be vulnerable around me, a black unicorn. I can feel her intense desire for giving and receiving love, specifically from me. I don't need my horn to tell me that.'

'S-so you still do, y'know...'

'We do sexual stuff regardless of whether she's playing filly at that moment. She's just not allowed to play with herself.'

'Oh... B-but I didn't know!' he repeated.

'That's true, and that's why I'm in a bit of a dilemma. I feel like punishing you would be unfair, because you didn't know about the rule and it strictly doesn't apply to you. On the other hand, it would also be kind of unfair to Stella if there was no consequence at all. Do you understand my position?'

'I guess. What punishment are we talking about?'

It was Celester's turn to frown. 'Why did you ask?'

'Well, if your rules are that fillies are not allowed to play with themselves, and we forget the fact I'm a rabbit for a moment... Even though I think I shouldn't be punished for breaking a rule I didn't know existed, I guess I want to show Stella, um, what do you call that?'

'Solidarity?'

'Yeah.'

'That's very kind and humble of you, but it feels wrong making you suffer the consequences for breaking a rule you didn't agree upon following.'

Rowan pondered for a while.

'Well, you already said you don't spank her, so how bad could those consequences be? It's about roleplaying, right?'

Celester nodded.

'So what's it going to be? Corner time? Writing lines?'

'Neither. Like I said, the punishment should fit the crime.'

One of his ears flopped as he gave her a confused look.

'If Stella has played with herself without my permission, I lock the door of my nightstand for a few days. That's where I keep our wand vibrator.'

'So, no orgasms for a while?'

Celester nodded again.

'And what about me?'

'Can you guess?' she asked, sounding almost guilty.

Suddenly, it dawned on Rowan.

'No... not chastity, right?'

Slowly, Celester nodded a third time. She gently caressed his back, mostly to feel if he was getting upset.

'B-but... but how? We gave my cage to those detectives, and-'

She did not respond.

'Did you buy me a new one?' he asked indignantly.

Celester sighed, then turned to Rowan and looked him in the eyes. Her horn began to glow softly, and her eyes dimly shone. An alien feeling manifested in Rowan's mind, as if the house of his emotional state suddenly had a guest over.

'Don't be afraid, Rowan,' she spoke quickly, but decidedly. 'I'm sharing my emotional state with you. That means you get to experience some of what I feel right now. I'm doing this so you know I'm sincere. Please let me talk and don't interrupt, because this is a difficult spell and I want to be able to keep it up long enough.'

'O-okay.'

'The night when I unlocked your cage and collar, I took photos of both of them. Mostly out of curiosity. I don't know exactly why, they intrigued me and it was a heat of the moment thing. Later on, I went looking online for a place where people might recognize it, because it by far doesn't seem like something you can just buy anywhere. Maybe I wanted to understand a little bit of how Azalea got her head where it is right now.'

Rowan listened attentively. Through Celester's telepathy, he could indeed feel she meant every word she was saying.

'It wasn't planning to use it already. I just wanted to have it ready for whenever a good moment did come up. Don't get me wrong, I wasn't waiting for you to misbehave. I just thought this would be a coincidence we could make use of. I understand it doesn't exactly remind you of pleasant times, but would be doing this to teach you something. I figured I might be able to help you in a way a therapist won't. Both your parents and Azalea have treated you like something less than a person. They didn't take your needs or feelings into account. It didn't even matter to them. I want to show you that we're different, and that you can trust us.'

'But how? And what does that have to do with me, y'know...' he said, ending with an unconfident hand gesture, somewhat akin to masturbating.

Suddenly, the glow disappeared, and Rowan no longer felt Celester's emotions. She took a few deep breaths before she continued.

'I'm sorry, Rowan. I should've put some more thought into this, instead of going by impulses. I thought I could teach you something about trust, by showing you that I will let you out.'

He slowly turned his head. 'Huh?'

'What? Did you really think I'd lock you up permanently?'

'Y-yeah... why not?'

'Because it's only a punishment. A temporary denial of access to your private parts. If I won't let you out, how can you prove that you're a good bunny that doesn't touch himself?'

'Dunno... but how does that work? I don't want you to lock me up at all, if I'm honest.'

Celester sighed. 'I understand. I'm sorry, Rowan. I shouldn't have done this. It's way too early for you to say "yes" to a dynamic like this, if ever.'

She slowly got back on her hooves. It took until she reached for the door handle before Rowan spoke up.

'Wait, please don't go,' he said hesitantly.

Before Celester could say anything, he continued.

'I still think punishing me would be unfair, but I'd also feel guilty towards Stella if you have let this slide. I don't want to be locked up either, so... I just don't know.'

She nodded. 'I think I understand how you feel. What if I just explain what I was thinking of, and you tell me if you'd be up for it, okay?'

'Can I still say "no" if I don't want to be locked up?'

'I'm only putting that cage on you if you genuinely agree to it. Let's go downstairs. We can discuss this further during breakfast.'

'Yeah, that's probably best,' he said, getting up carefully to not strain his paw. 'That way Stella is in on this as well.'

'Come,' Celester said, extending her empty hand. 'I'll help you down the stairs.'
