Sucy watched from her corner of the playpen while Red was busy stacking some large building blocks together haphazardly. The Miqo had just recently been changed into her night time diaper and onesie. The onesie was black and decorated with purple haired witches flying around on brown brooms. A pinkish purple pacifier clip had a black pacifier attached to it that was currently in Red’s mouth. The diaper Red had on underneath couldn’t have been a worse match to her outfit, but it was out of the pack that was already open, and neither Wan nor Red felt like opening a new pack. It was a pink diaper with a white center and probably some kind of decoration going down it. Sucy didn’t get to see as Red’s onesie was snapped shut by the time she had been let in the nursery following Red’s messy diaper change. Thankfully the onesie retained the outfits color theming by covering most of the diaper, only leaving very visible hints of pink through the leg holes and a very knowing shape to Red’s bottom. It was obvious the Miqo was in a diaper, but the diaper itself was covered enough to keep the outfits cohesion.

Red’s red haired cat tail flicked and her cat ears twitched as she did her best to combine the building blocks while her hands were covered with a pair of thick pink mittens that had been locked on her during dinner. The struggle of being able to operate the blocks while her hands were useless was adorable, but also seemed to be adding some stimulation to the otherwise mundane activity of building blocks. The twitching of her ears and flicking of her tail betrayed her investment in the activity.

Sucy was sitting in her own corner of the playpen. She was still wearing her outfit from earlier that day: a pink and purple tye dye crop top decorated with a white ice cream cone, and some very short jean shorts. Sucy, who had the benefit of mittenless hands, had taken to building with a series of magnetic tiles: plastic squares and triangles that attached together with the force of the tiny magnets embedded inside them. Something that required a more delicate touch than the large building blocks Red was entertaining herself with. Sucy had finished constructing a ufo looking shape before speaking up.

“This all ok with you Red?” Sucy said carefully sitting the structure she had made on the floor of the play pen.

“Yeah,” Red said letting the pacifier drop from her mouth. While Red had started the play session deep in little space, she had since fallen back somewhat into her normal head space. “I don’t know why I was so concerned to be honest,” Red admitted. “It’s social circles combining, I guess. You’re a friend but not like a baby friend you know. It’s not like I thought you’d be upset it’s … I dunno.” Red went back to trying to place another block having failed to find the words to say. She had successfully constructed a floating arm, a section of building blocks that supported itself without touching the floor of the play pen. She seemed proud of her feat of engineering.

“I get it,” Sucy crawled over to Red. “You’re good. I’m just happy I get to see you be all baby. You were really cute.” Red blushed and her ears flattened. Her blushing was caught short by Wan, Red’s girlfriend and mommy, opened the nursery door. The Biscotti had gotten dressed in her own pajamas: a white tank top that threatened peeks at her uncovered bosom, and some baggy pink sweat pants. Wan’s tail wagged at seeing Red and Sucy playing, and Red’s ears perked up at the barely hidden bosom of her girlfriend. Red subconsciously put her pacifier back in her mouth and started audibly suckling.

“Ok time for bed,” Wan announced with authority. “It’s getting late.”

“It’s like nine!” Sucy complained.

“That’s late for a baby,” Wan pointed out. Red looked to Sucy and shrugged with a smile. Wan helped Red out of the playpen while Sucy stepped over the short rails on her own. Wan and Red moved to the crib. Wan sat down and Red laid across her lap in a familiar position. Wan produced a large bottle filled with what looked like chocolate milk and Red eagerly put the nipple in her mouth, suckling almost as eagerly as she had suckled from Wan herself earlier that day. “Well now we have to figure out where you’re going to sleep,” Wan said to Sucy.

“You don’t have a guest room?” Sucy asked.

“You’re lookin at it,” Red said the bottle’s nipple escaping her mouth for a moment. Wan pushed Red’s head back into place over the bottle and delivered a quick swat to her thigh.

“She is right though,” Wan adjusted Red slightly as she continued to suckle. “You’re gonna have to sleep in the crib with baby Red here. I hope you don’t mind.” Sucy looked to the crib Wan and Red were currently occupying with a sense of hesitation.

“Oh,” Sucy said and then paused.

“Of course, you understand that I can’t leave the crib open and let Red run around and hurt herself.” Red had suddenly stopped suckling and giggled into Wan’s chest. “And if you’re stuck in the crib with baby Red, well …” There was a pause as Sucy processed what Wan was getting at, suddenly blushing as she did.

“Woah woah woah I’m not a baby.”

“In my experience it takes one to know one,” Wan said smirking. “Red?”

“Das a baaaaaby!” Red pointed at Sucy.

“Well, you heard her.” Wan laughed. Sucy pouted and blushed, crossing her arms. “It’s how it has to be I’m afraid,” Wan spoke as if the outcome she was fishing for was just awful, though it was clear by the snickering face of both her and Red that it was by far the most desirable outcome. Red crawled off Wan and made her way to Sucy, sitting on the floor in front of her and getting in close.

“You can always say no,” Red whispered in a state between her adult self and her baby self that was oddly seductive. “You can play along too. You got to watch me play. It’s quid pro quo.”

Sucy blushed as she looked at Red. She had a choice here. She could say no. She would probably still have to sleep in the crib, but it would be in underwear, and it would be left open for her to use the bathroom as she wished. She could remain Red’s friend and on her vanilla circle. Or she could take the invitation to play along and cross over into that other circle of Red’s. With that crossing over she would lose something of herself. Innocence wasn’t quite the right word, but it wasn’t far off. She would no longer just be an observer to Red and Wan’s dynamic, but a participant. Additionally, if she played along, she would always be one moment away from being diapered along with Red, and probably be one moment away in the other direction of being Red’s baby sitter.

What Sucy found swaying her decision was what Red had said. “Quid pro quo.” A phrase that seemed much too complex for the Miqo in a onesie and diaper, but a phrase that was ringing true. Sucy had been brought in as an observer to this unique and special dynamic. Now in exchange they wanted her to participate. It seemed only fair. Sucy had been saying to Red all day today, and for several days before, how her diapers and her dynamic didn’t matter. Now that would be put to the test. If it didn’t matter, then surely she wouldn’t mind wearing one as well.

A haunting thought was also echoing all this decision making. She might like it.

“All you gotta do is say no right now,” Red said putting her mittens over Sucy’s hands and speaking seriously. “Say no right now and we stop.” Red and Sucy locked eyes for a long moment, the blush on both their faces growing.

“I’m…” Sucy stopped for a moment, her stomach full of butterflies. “I’m not a baby like Red!” she pouted playfully. “You can’t put me in a diaper like her.” Red smiled big.

“We’ll see about that little lady,” Wan picked up the role play and grabbed Sucy’s hand. “If you’re sleeping in the crib, you need a diaper and that’s final.” Wan gently pushed Sucy toward the crib. Sucy let herself get pushed. She laid down on the bed more than Wan forced her onto it. Just like she only wiggled slightly as Wan pulled down her shorts and her panties.

“You can’t make me I’m not a baby,” Sucy whined while she lifted her bottom for Wan to slide another one of the diapers Red was wearing under her. Now Sucy could see that the middle part of the pink diaper was indeed decorated, with fade when wet picture of bunnies frolicking.

“You look like a baby to me,” Red smirked from the edge of Sucy’s vision as Wan applied baby powder and taped up the diaper with practiced precision. Sucy laid there for a moment, feeling the soft and thick padding between her legs that crinkled as she moved. She did like it. So much that even Red and Wan looked on at her with big grins as they waited for Sucy to continue their role play.

“This is stupid,” Sucy pouted and crossed her arms all while butterflies flew in a frenzy in her tummy.

“Settle down now, it is getting close to bed,” Wan said calmingly. She grabbed Sucy’s shirt and tossed it off her.

“Hey!” Sucy yelled, covering her bare chest. “I don’t normally sleep naked, you know."

“Babies sleep nakey all the time,” Red explained.

“I can get you a onesie to wear if you’d like,” Wan offered. A checkmate. The blush on Sucy’s face was her answer.

“Mommy,” Red said deviously. “I think Sucy might try and get out of the crib. She seems rebellious.”

“You know I think you’re right sweetie,” Wan said with a hand on her hip. “We should make sure she stays safe in the crib.”

In a flash Wan and Red both got to work. Restraints were hidden underneath the mattress of the crib, and attached the top and bottom of the crib. Sucy fake struggled as Wan secured her wrists and Red her ankles into those soft restraints. There was a generous amount of give befitting someone who was being tied to the crib for the first time. Sucy had a great deal of movement, but not quite enough to reach her diaper, and not quite enough to escape the confines of her crib.

“There nice and safe,” Wan smiled as she shut the door of the crib and locked it shut. Sucy was left loosely pinned to the crib by the restraints. Red was gently resting almost on top of her. Their diapers were gently touching. A fluttering smile was on Red's face. Sucy could almost see the butterflies in Red’s stomach threatening to escape. “Try not to have too much fun girls,” Wan said knowingly. She went to the door of the nursery and turned the light off. Before the light was even off, Red was lustfully at work on her friend. Her mittens caressed Sucy’s exposed breasts, and she gently pressed against Sucy’s tummy, right above the waistline of her diaper. Sucy suddenly felt a need to pee that she didn’t know she had been suppressing. Red apparently sensed this.

“Let it out little baby girl,” Red bit her lip. “Then I can show you how good these can feel.” Sucy acted almost immediately, finding herself caught up in the moment. She sat up as much as her restraints would allow, which was a fair bit. With the aid of gravity, Sucy pushed urine into her diaper, and it grew warm as it dutifully absorbed all the escaping liquid. The weight of the diaper increased and the softness changed into a squishiness that was not at all unpleasant. Sucy laid back down and Red took the same position she had earlier. Lightly straddling over Sucy with her diaper now more deliberately touching Sucy’s. Sucy could tell by the added weight that Red’s diaper was as wet as her own. There was no telling when she had wet it.

Silently Red fished out a magic wand from a pocket on one of the crib walls. Even with mittened hands she was able to operate the device. Red pressed the vibrator in between her and Sucy’s wet diaper and they both felt the pleasant sensation permeate through their soaked padding. Sucy found herself involuntarily grinding against the vibrator in a matching rhythm to Red. She felt the vibrations move through the warm, wet, and squishy padding that was pressed against her privates. She felt the gentle resistance of her restrains keeping her secured. She reached out and grabbed the bars of the crib. She met eyes with Red, the similarly diapered Miqo working the magic want with mittened hands.

The wet diaper. The Restraints. The crib bars. Red. All sensations melded into one overwhelming sensation of helplessness that then transformed into a burst of excitement. Sucy let out a moan as she came in her diaper, the new liquid spasming out of her in bursts being absorbed just as easily as the urine. Red laughed as she kept working the wand on her own diaper before making a less dramatic, but no less definitive, sigh.

With some shallow breathing, post nut clarity washed over the two girls in the crib and they both suddenly grew embarrassed.

“Oh gosh Sucy I’m sorry,” Red stammered. “I got carried away there.”

“It’s fine,” Sucy stopped Red from spiraling. “I could have stopped you if I wanted to.” she laid down on her back. “I think maybe I got caught up in it a bit too.”

“Ugh we should have talked about this more,” Red used her mouth to help free herself from her mittens. “I just sprang all this on you,” with her hands free, Red moved to free Sucy’s hands and ankles as well.

“It’s fine Red seriously,” Sucy sat up once she was freed and the two girls in diapers sat across from each other locked in the crib. “That was a little sudden but …” Sucy blushed. “I really liked it.” Red blushed as well and looked away. “Don’t think too much about it ok. It was fun. Come on let’s lay down.” Sucy did and gently pulled Red with her. The two now lay next to each other, forced close by the confines of the crib though they weren’t quite cuddling. “We should get to bed. It is bed time for us babies right?”

“Right?” Red smiled. Red put her pacifier back in her mouth and brought the covers over the both of them.

*****

Wan, Red, and Sucy were walking along the path to Sucy’s apartment. This time Red’s short pink sundress was not afforded the protection of a petticoat, meaning her diaper was constantly peeking out as the dress swayed with her walking. Wan had adopted a look that was similar to Sucy’s the day before. A plain white short sleeve t-shirt with more modest jean shorts. Finally, there was Sucy, wearing a white band t-shirt with the band logo on the front in a colorful spray paint like pattern of purple, pink, and green and a plaid purple and black skirt.

“Looks like I’m good,” Sucy said noting the lack of a protective tarp of her apartment meaning the fumigating was done. “Thanks for letting me stay the night,” Sucy said knowingly.

“Any time sweetie,” Wan answered with a smile.

“It was nice having you over,” Red said, her ears flattening with a blush. “we’ll have to do it again some time.”

“For sure,” Sucy answered eagerly. “I’d love to do that again,” Sucy started to walk back to her apartment but Wan gently stopped her by grabbing Sucy by her skirt.

“Not yet,” Wan said in a stern tone. She placed Sucy in front of her and spun her around so they were facing each other. In a quick movement Wan’s hand pressed underneath Sucy’s skirt. Sucy felt the diaper press against her, and felt the cold dampness that indicated it was wet and had been for a while. Wan could tell as well judging by her smirk. The diaper was dry when Wan had changed her into it that morning. “Good girl,” Wan cooed. Sucy blushed and Red giggled. “Now turn around,” Wan said even though she was spinning the girl around herself not waiting on her to respond.

“What?” Sucy’s blush grew with her confusion, but things were made clear as Wan pulled back both the waistband of Sucy’s skirt and her diaper with the same hand. She looked down into the diaper before letting the waistbands fall back into place.

“Well, we’re not there yet,” Wan smiled. “We’ll get there soon I bet.” Sucy’s blushed reached it’s peak. “Run back home little girl.” Wan patted Sucy on her bottom and Sucy felt her diaper press against her. Too blushy to respond, she simply made her way back to her apartment.
