“Merry Christmas!” Jason shouted as he came in the front door. He looked tired after his long drive.

“Merry Christmas, Jason.” Holly greeted him with a hug and a kiss on the cheek. She was dressed in a festive green Christmas dress with white trim, and a matching green Santa hat.

Jason was surprised to see her. He dropped his bag on the floor, glancing past her quickly before meeting her eyes. He smiled. They hadn’t seen much of each other in the past few months. “It’s good to see you, Holly. Are you and Darcy...” he trailed off, again looking around for signs of his fiancé.

She motioned zipping her lips. “I won’t ruin the surprise.”

His smile widened. “Let me hit the bathroom and freshen up real quick.”

“I’ll be by the tree.” She flounced into the living room, her short skirt bouncing with each step. Holly looked over her shoulder, catching him watch her. She winked and disappeared into the other room. The living room was lit only by the Christmas lights on the tree, a multicolored glow illuminating one new, brightly wrapped, large package in the center of the room. A thick green ribbon framed the box, tied off on top in a massive bow. A card hung from the bow, written in large, elegant, cursive script “To: Jason. From: Santa.”

Holly turned the stereo on, softly playing Christmas music in the background. She then plopped down on the couch, stretching out and waiting. She’d been helping Darcy surprise Jason for years, and even though Darcy had been trying to push Holly out of their lives for the past few months, Christmas was a time to put old fights behind them and be together with the ones you loved.

She didn’t have to wait long; Jason came in, having changed into a tight black sweater. He looked around, eyes landing on the present.

“Go ahead and open it,” Holly said.

“Should we wait for Darcy? Or is...” Again he trailed off, looking at the box. It would be cramped, but it could potentially contain his fiancé.

“Don’t ruin the surprise,” Holly said, watching.

He grabbed the ribbon, and with a calculated tug, pulled apart the bow, the ribbon sliding off the package to the floor. He grabbed the lid, pausing as he noticed the air holes on the back side of the package. He glanced at Holly, who was merely watching from where she lounged on the couch, a content smile on her lips. Jason lifted the top of the box off, staring down into his gift.

“Mmmphnnn!” came a muffled cry from the box.

Jason was speechless, staring down into the box. His fiancé was, as he suspected, inside, but this was not what he’d expected.

The box shook as Darcy struggled inside. She was laying on her back on a cushion on the bottom of the package. Her legs were frog tied and her wrists bound to her upper arms with green tape that matched the ribbon wrapping the package. More of the ribbon was tied around her, wrapped tightly over her pert breasts, just covering her nipples, the strands disappearing around her back and crisscrossing across her stomach and a single thread of ribbon going down between her legs, over the thick pink diaper she was wearing. Another bow was tied neatly over the top of her diaper, which was notably the only clothing she was wearing, and certainly not part of her normal attire. Her hands were trapped in thick, padded pink mittens, that matched the pink pacifier strapped in her mouth.

“What do you think?” Holly asked, having sauntered up behind Jason while he was taking in his gift. She looked over his shoulder down at her best friend. Darcy glared back, shaking and struggling, screaming into her gag. Holly was bigger and stronger, and it had been easy to overpower the smaller girl. Darcy fought the entire time, but Holly had managed to strip her naked, tie her up, and put her in a diaper before wrapping her up as an unwilling Christmas present for her own fiancé.

“Mmmmphnnn! Hmmmph mmmph!” she cried around the massive rubber nipple stuffed in her mouth.

“Hang on.” Jason reached in and tried to pull the pacifier out of her mouth for her, but it was strapped in too tightly. “Did you do this?”

“Nnnnph!” She shook her head furiously, the cute pigtails Holly had tied her hair in swishing against the sides of the box.

Jason looked back at Holly. “What’s going on?”

Holly grinned ear to ear. “She told me you wanted this.”

They both glanced back at the helpless girl in the box.

“To try ageplay. To see her in diapers. To be your helpless baby girl.” Holly leaned in closer to Jason.

Jason gulped. He tried to move back, but Holly’s hand found the bulge in the front of his jeans, stroking him.

“I’m guessing she never did do that for you?”

Jason shook his head. Beneath them Darcy continued to struggle uselessly, screaming for attention.

“I get it,” Holly said. “She can be so immature. And now she’s being such a selfish little brat, trying to keep you all to herself. When we were friends before you and her even met! I miss you.” Her face was inches from his, her lips almost meeting his, but she stopped, looking back down at the furious girl in the box. “I’ve missed her too. The three of us could have so, so much fun together.” She reached down, stroking Darcy’s cheek above her gag.

“Nnnnnmmmph!”

Jason ran his tongue around his suddenly very dry mouth. Darcy looked up at him, staring into his eyes, pleading incoherently into her pacifier. She looked so cute like that, all wrapped up, both in the ribbons and the diaper. She’d been willing to wear a cute schoolgirl uniform, she was happy to let him tie her up from time to time, but she’d balked when he’d asked to put her in a diaper. She didn’t understand the appeal, and he hadn’t pressed it. But to find that she had told Holly about it, and somehow Holly had convinced her to do it...

No, clearly Holly hadn’t convinced her. However she’d managed it, Darcy clearly didn’t want to be tied up in a diaper. Taking one last mental snapshot of his infantilized fiancé, he reached again for the pacifier gag. Darcy moaned gratefully and leaned her head to the side so he could reach around for the clasp behind her head. He froze, feeling the lock. “Holly, where’s the key?”

Holly pouted, pulling a key on a chord around her neck from between her breasts. Jason reached for it, but Holly snatched it back, clutching it in her fist. Her frown turned into a mischievous grin. “Why?”

“Come on Holly. She wants out.”

“I’m sure she does. But what do YOU want?”

Darcy had gone quiet, her eyes darting back and forth between them.

“I want to hear what she has to say?” Jason again held out his hand for the key.

“Do you want to hear her say 'no?' To say that she doesn’t want to indulge in your fantasies? That she doesn’t want to share you with me?”

Jason’s hand slowly lowered.

“Mmmphnnn!” Darcy cried, struggling again, desperate to get his attention.

Holly put the key back between her boobs, thrusting them out provocatively as she did so. “Tomorrow we can all have an adult conversation. Tonight, well tonight you should play with your present.”

Jason’s fingers clenched the edge of the box. Darcy flailed her bound arms and legs, her breasts jiggling under the tight ribbon binding them.

“She just needs to be shown how much fun being your diapered little girl can be. Here, listen close.” Holly pulled out a small remote out of her pocket and clicked a button. Darcy immediately squealed behind her pacifier, squeezing her frog tied legs together as much as the thick padding between her thighs would allow. “Shhhh,” Holly said, leaning in and putting her finger to the pacifier. Jason cocked his head to the side, listening. A faint buzzing could be heard coming from Darcy’s diaper. “I’ve been playing with her all day. You can show her just how good her diapers can feel.”

“Mmmmmph!” Darcy thrashed, the whole box shaking. She was so frustrated. Holly had put the powerful little vibrator in her before sealing her in the diaper, keeping the helpless girl desperate and horny for hours, before shutting it off shortly before Jason arrived. In mere seconds the toy brought her right back up to the brink, her need pushing aside all her thoughts of trying to convince Jason to let her go.

Holly placed the remote in his hand. He didn’t recognize it; it definitely wasn’t one of their toys, but it was intuitive enough. He pressed a button, and the buzzing got louder, as did his fiancé’s desperate moans. “Does that feel good, baby girl?”

Darcy shook her head, screwing her eyes shut, but her moans definitely said yes. Her nipples were plainly visible under the ribbon wrapped over them.

Jason reached in, pressing on the front of her diaper. Darcy spread her legs, thrusting her hips up to meet his touch. “It’s okay, you can admit it.”

Darcy told herself that if she just stopped resisting, he’d make her cum, and then she could think straight, and he’d release her. It wasn’t because the vibrator in her diaper did feel really good, and that in spite of how furious she was that her friend had forced her into this situation, her friend that seemed to want to steal Jason from her, that Jason himself hadn’t immediately released her and was siding with that backstabbing bitch, it was really turning her on how he was treating her. Darcy nodded, rolling her hips, trying to grind her padded pussy against his hand.

Holly stepped back and dropped silently to her knees. Jason at first tried to push her away when she went for his belt, but she persisted. “Keep going,” she told him as she unzipped his fly.

He turned the vibrator up again and traced the ribbon bound around her body. “What if I unwrapped my present?” His fingertips glided across her sensitive skin, following the ribbon across her boobs, down over her stomach, to the top of her diaper. “If I unwrapped you, what would I find?” He gasped, but Darcy was too distracted to notice. Holly ran her tongue along the length of penis. She was very good with her mouth. Darcy was no slouch in that department either, but he had missed Holly’s talents. Just like the ageplay, Darcy had shot down the three-way that Holly had proposed, and Jason had assumed that would be the end of it. And now here he was, celebrating Christmas with his fiancé utterly helpless, tied up and diapered for him to play with, while his ex was giving him a blowjob.

“Would I find my baby girl wet?” he asked. He squeezed the crotch of her diaper, unable to tell if it was wet or dry, but the action made Darcy moan deeply. He stuck a finger in through the leg band, feeling around. The vibrator was nestled in place right over her clit, humming away. He stroked her opening; she was dripping. “It’s a good thing Holly put you in diapers.” Upon hearing her name, Holly wrapped her lips around the head of his cock, slowly taking the whole thing into her mouth, deep throating him. “You’re soaked,” he told Darcy, slipping his finger inside her. The helpless girl threw her head back, her arms and legs straining against the tight tape securing them. Jason grabbed the ring on the front of her pacifier, and with a firm tug, forced her to look up at him.

Darcy opened her eyes, staring up at her fiancé. She could hear the slurping noise on the other side of the thin cardboard walls of her prison. She knew what they meant. She couldn’t see it, but she could imagine Holly there, on her knees, sucking her man’s dick while Darcy was reduced to a helpless baby, sucking on a pacifier. She’d been so threatened by Holly and Jason’s history, so furious at the idea that Holly might try to steal him from her. It wasn’t just the vibrator buzzing away at her pussy. She found her situation strangely arousing.

“Do you want to cum?” he asked her.

She needed it so badly. Darcy nodded, moaning into her pacifier.

“Do you want me to make you cum in your diaper?”

Her diaper. It was hers. Darcy nodded again, biting hard into the rubber nipple stuffed in her mouth.

“Are you going to be a good girl for me?”

What if after he was done with her tonight, he didn’t let her go? She nodded, her pigtails flapping beside her head.

“Are you going to be a good girl for us?” His breathing was getting faster.

What if he decided to make Holly his wife instead of her, and they kept her as their baby, their toy to humiliate and play with? “Mmmhmm,” she moaned, nodding rapidly.

He grabbed the crotch of her diaper, pressing the vibrator harder against her even as he turned it up. He dropped the remote and grabbed Holly by the hair with his other hand, partly to guide her, partly just to steady himself. “Cum for me, baby girl.”

“MMMMGGGGGG!” Darcy threw her head back and screamed in her pacifier gag. Jason’s grip tightened as he came, shooting his load into Holly’s mouth. Orgasms quaked through Darcy’s helpless body. It was too much; she thrashed and flailed, but she couldn’t escape. Jason kept his grip on her crotch while he shot his seed down Holly’s throat.

Finally he emptied his balls, leaning on the edge of the box, panting. Holly looked up at him, thick white strands of his jizz dripping down her chin, and she handed him the remote for the vibrator. “Thank you,” he said, taking the remote and turning the toy off. In the box, Darcy was limp in her bonds, panting around her pacifier gag. Jason reached in and scooped her into his arms. She’d always liked how much bigger and stronger than her he was, how he could pick her up with ease, but now she felt especially small, held securely in his strong arms. He held her close, one arm around her back, sticky with sweat from her intense orgasms, and the other hand cupped under her diapered butt, the padding now noticeably wetter. She could see Holly over his shoulder, still on her knees, smiling up at her, her fiancé’s cum still dripping from her lips.

“Did you enjoy that, baby girl?” Jason asked, bouncing her a little, patting her diapered butt.

Darcy was still in the afterglow, but the reality of what had just happened was setting in.

Holly stood up, wiping her mouth. “Did you enjoy your diapers?”

Her already flushed cheeks turned redder, and she tried in vain to wrap her arms around Jason.

“You made me very happy, baby girl.” He turned to face Holly. “You both did.”

“It was my pleasure. I’ve missed you both.”

“Do you want to apologize to Holly and thank her?” Jason asked.

Darcy went stiff in his arms. Holly pulled the key out from around her neck and dangled it in front of Darcy’s face. “Do you want your paci out?”

Darcy had hated the thing from the second Holly had forced it into her mouth and locked it around her head, how it robbed her of the ability to reason with the two of them, how it was a pacifier of all things, such a babyish gag. But now, if they took it out, what would she say? What could she say, after Holly had already sucked Jason’s dick while he made her cum in a diaper. What could she say, to try and roll that back?

Jason pulled her back so he could look at her. All the tentativeness that had been in his face when he’d first found her like this was gone, and with it she suspected the window of opportunity for her to try to assert any control. She’d said no to the diapers, she’d said no to letting Holly into their relationship. But Holly had said yes, and now Darcy was in diapers, and Holly was very much in their relationship.

Darcy felt Holly’s fingers on the back of her neck, and with a click, the lock was open, and the pacifier gag was pulled from her mouth.

“Did you have something you wanted to say?” Jason asked, holding her to face Holly.

“I’m sorry...” she mumbled quietly.

“What was that?” Holly asked.

“I’m sorry,” she repeated, slightly louder, her eyes downcast.

“Sorry for what, baby?” Holly asked, lifting her chin so their eyes met.

“I’m sorry I tried to push you out of our lives.”

Holly beamed. It had been coerced, but that’s what she really wanted. “It’s okay, little girl. You’re my best friend, and always will be, even if you can be a little immature and need to be taught how to share every now and again. That’s what I’m here for.” She patted Darcy on the head, making the infantilized girl blush harder. And then she surprised her by grabbing her and kissing her.

Darcy spluttered in shock as she found Holly’s tongue in her mouth. She could taste Jason’s cum in her friend's saliva.

Holly pulled back, staring deeply into Darcy’s eyes. “Did you have something else you wanted to say to Holly?” Jason asked. He squeezed Darcy’s butt through her diaper, and he could feel himself getting hard again already.

Darcy just stared at Holly, still too stunned to remember what they had wanted her to say.

“Do you need a reminder?” Holly asked, gently stroking the side of her face.

Darcy nodded, squirming slightly as Jason played with her butt.

Holly leaned in close, their noses touching. “You wanted to thank me,” she whispered.

“Thank you,” Darcy repeated.

“For tying you up,” she continued.

“For tying me up.” Darcy wiggled her bound arms and legs, reminded of her helpless state.

“And putting you in a diaper,” Holly said, her lips just brushing Darcy’s as she spoke.

“For putting me in a- in a diaper.”

“And making you try new things. Fun things.”

“And making me try new and fun things.”

Holly put her lips to Darcy’s ear. “Show me how appreciative you are.” She gave Darcy a quick peck on the lips and then flopped back on the couch. She leaned against the arm and threw one leg up over the back, her fingers slowly peeling back the hem of her dress.

Darcy quickly glanced at Jason. He too kissed her. “Thank her,” he told her, and then set the diapered girl on the couch on her knees and elbows in front of Holly.

Darcy could see from this angle that Holly wasn’t wearing any panties under her short skirt. Her naked pussy was glistening wet, sparkling almost magically in the multicolored blinking Christmas lights from the tree.

“Come here, baby.”

Darcy crawled tentatively forward, her diaper crinkling with each movement. Holly grabbed her pigtails and guided her in between her legs. Darcy froze, poised with her face above Holly’s pussy.

“Come on, you know what to do.”

Holly pulled her forward until her lips met Holly’s. Darcy stuck her tongue out, tasting her best friend.

“Good girl,” Holly praised, petting her hair.

Slowly, Darcy started to lick.

Jason watched, gently stroking his now fully erect penis. He stepped up behind Darcy and tugged her diaper to the side, exposing her pussy. Darcy tried to look up, but Holly held her in place. “Just keep going, baby. You’re doing great.”

Darcy kept licking, wiggling her hips and raising her ass up into the air. Jason didn’t make her wait long, thrusting into her wet pussy. She moaned loudly into Holly’s crotch, licking deeper.

Holly gasped. She met Jason’s eyes, smiling at him while he fucked the bound and diapered girl eating her out. In the cold light of day tomorrow things might be different. She’d had a moment of doubt when Darcy had fought to keep her from stripping and restraining her. She might have gone too far, and the possibility that Darcy would never forgive her crossed her mind more than once. She’d powered through though; it wasn’t like Darcy was exactly forgiving her for suggesting joining their relationship. But now that she had Darcy in between her legs, even if tomorrow Darcy decided that, with the benefit of experience, she truly wasn’t interested in an open relationship, then she’d have to accept that. For now, her best friend was sucking her clit with genuine enthusiasm while she was getting railed in a diaper by her fiancé, and that was a Christmas miracle. Darcy might find she quite liked this new dynamic. Or she might want revenge. She could decide to punish Holly. Jason certainly would be on board, and Holly definitely wouldn’t mind some punishment and discipline doled out to her. For the moment though, she was on top, and she was going to make the most of it. She tightened her grip on Darcy’s pigtails, guiding her plaything to the perfect spot. “Good baby,” she said, her voice breathy and husky. She was getting close.

Darcy kept licking. She’d never done this before, but Holly wasn’t shy about guiding her, using her hair like reigns. She found she was fixated on making Holly cum. She wanted to do a good job, to please her. They’d forced her to apologize and then thank them for doing this to her, and to her surprise, when the words had come out of her mouth, she hadn’t been lying. She was sorry she had been threatened by Holly. She was grateful that Holly had ignored her attempts to push her away, had forced her into this position. She was happy to be between Holly’s legs, servicing her, showing her gratitude. Jason wasn’t going to choose Holly over her. His dick inside her had never felt as good as it did right then. She wanted to make him happy too. She wanted both of them. She needed both of them. Darcy carried the momentum of his powerful thrusts into her through her gift-wrapped body and plunged her tongue deep into Holly’s snatch.

“Oh yes!” Holly cried, pulling Darcy hair.

Darcy wrapped her lips around Holly’s clit, sucking the sensitive cluster of nerve endings into her mouth and flicked her tongue over her button.

Holly’s legs wrapped around the back of Darcy’s head, locking her in place. “Yes! Yes!” she cried.

Jason pumped faster, and turned the vibrator back on against Darcy’s pussy. She squealed, but Holly held her in place, and she kept licking and sucking.

“There’s a my good baby girl!” Jason said. He threw his head back, his whole body tensing and releasing as he came hard inside Darcy. Her vaginal walls clenched tightly around his pulsing member as she came with him.

“Oh fuck!” Holly cried out, her fingers clenched deep into the couch cushions to hold on as she rode the wave of the most powerful orgasm of her life, her juices gushing into Darcy’s mouth.

Breathless, Jason pulled out of Darcy and pulled the diaper back over her dripping pussy. Slowly Holly’s legs unfurled and she let Darcy up for air. Darcy gasped, her body limp on the couch in between them as she tried to catch her breath.

“You still haven’t unwrapped your present,” Holly said.

Jason wasn’t sure if she was referring to the diaper or the ribbon and tape still wrapped around Darcy. She managed to lift her head to look up at Holly.

Jason lifted her up and sat down on the couch, laying Darcy back down on her back, her head in his lap. The ribbons were all eschew, and he tugged them back up into place, covering her nipples. She wiggled and moaned when he touched the still hypersensitive nubs. “It can wait until morning,” he said. He looked down at Darcy, stroking her hair. She nodded, still too spent to speak.

Holly smiled, running her fingers along Darcy’s thigh, making her best friend squirm. “Merry Christmas.”
