So I was a little reluctant to post this, but here goes. Hope it's ok..
Emma and Regina had dozed off in a tangle of arms and legs. It was around three in the morning when Regina's eyes shot open in panic. She could sense something wasn't quite right. Blinking a few times, she accustomed to the darkness and saw a shadowy figure sat in the armchair at the foot of the bed, watching them. She sat up, trying not to disturb the sleeping blonde.
"Love is weakness Regina. You of all people should know that by now."
"But I killed you! I watched you crumble in a pile of ashes! How are you here?" Regina asked with trepidation. She tried to summon a fireball but the Evil Queen extinguished it and restrained her hands in a similar fashion Emma had done to her in New York.
The Queen spoke. "Now, now dear. I'm not here to fight! I have to say, I'm quite awed that you finally followed through on those dark thoughts we had about the Savior. Tell me, is she as delicious as we imagined?"
Regina struggled against her constraints, feeling the anger rise, she spat, "You leave her alone! Her heart belongs to me!"
The Queen laughed as she stood up and walked across the room and stood over the naked Savior. "I know Regina! That's why I'm here." She flipped the still dozing blonde onto her back and took in the sight of her perfect form briefly before plunging her hand in and ripping out her heart. "I wouldn't be able to take this if she didn't!"
Emma woke up with a jolt and looked confused between the two Reginas. "Wh-what's happening? She's back?"
Regina shouted, "put it back before you break it! Please, don't do this!"
Emma looked up noticing her beating heart was in the Queen's hands and she felt a strange mix of desire and hatred as the regal woman carressed it gently.
"Oh don't worry dear, I'm quite fond of the Savior, as you are well aware. It's not her heart that I intend to break." She bit her lip and Regina could do nothing but bow her head in shame as she knew exactly what her evil half intended to do. It was certainly one of her darker fantasies and suddenly she was conflicted with wanting and shame.
"Regina, you might think you destroyed the darkness when you split us, but it's still there. Deep down, you know the truth! I intend to simply bring it back to the surface." The queen whispered into Emma's heart and she instantly stood from the bed. She could feel the shame on her cheeks as her center melted. The Queen may have been holding her heart, but Emma quite honestly would have given it to her willingly and was ashamed at how turned on she was getting. This is still Regina. She is a part of her and I love all parts of her.
The Queen smirked as she used her free hand to grip Emma's sex and licked her lips.
"Oh Regina, she isn't as pure as we imagined. I think she is enjoying this, aren't you Savior? Answer me!"
Emma spoke and a tear trickled down her cheek as she looked at Regina who was still cuffed to the bed. "Yes."
"Yes, what?"
"Yes, your majesty."
Regina avoided Emma's gaze, ashamed of how wet she was becoming herself and how laboured her breath was.
The Queen stripped down to her undergarments with a flick of her wrist and Emma groaned at the ensemble.
"I'm glad you like what you see, Miss Swan. Now then. You know what to do. Kneel." The Queen placed one foot on the bed and looked over at her weaker counterpart to make sure she was observing as Emma did what she was told. Regina couldn't look away no matter how hard she tried. Her chest heaved as she watched the blonde lick and suck her evil half.
"More, Savior. Fill me."
Emma obliged, increasing her pressure and inserting three fingers into the Queen's dripping cunt.
"Not like that! Put that magic of yours to good use and give me what I want!" The Queen barked.
Emma blushed unsure of what exactly the Queen wanted from her. She looked to Regina for help.
"Tell her what she should do, Regina. You know!"
Regina sighed and visibly shuddered. She closed her eyes and spoke in almost a whisper. "She wants you to.. to.. grow a penis."
Emma's eyes widened and the Queen laughed evilly as the blonde stared at Regina for confirmation. "How do I do that Regina? I wouldn't even know how to begin."
"Oh use your magic, dear. Focus on what you want and make it so." The Queen drawled.
Emma concentrated on the space between her legs and was surprised and fascinated when her genitalia began to transform into what she imagined. She tingled with the magic and smiled in triumph at the Queen.
The Queen crawled onto the bed and hovered over Regina's restrained body. The sheets had long since fallen to the floor and she was completely exposed. The Queen flicked her wrist and Regina's legs were tied and pulled apart by magical chains. Emma gasped at the sight and saw the telltale glimmer of wanting in Regina's eyes.
"You are going to watch the Savior fuck me and you're going to enjoy it." The Queen taunted a helpless Regina.
Emma got on the bed and straddled the Evil Queen who had lain horizontally between Regina's legs. As she entered and began pumping rhythmically inside the Queen, she felt the magic and new sensations doing things to her body that she never thought possible. Regina watched her evil self getting fucked by a well endowed Savior and gushed endlessly at the sight.
The Evil Queen laughed and flipped herself onto all fours so that she could tease Regina. "See! It isn't that easy to snuff out the darkness. It's who we are Regina. You need me!" She was hovering so close to her sex and with every thrust from the Savior, she moved closer.
"Tell me Regina!"
"Yes! I need you! I like the darkness. I want you back inside me!" She sobbed at her pathetic weakness.
"See! That wasn't so hard was it!" The Queen sassed and rewarded her weaker self with the touch she so desperately needed. Emma could feel her own orgasm building intensely as the Queen fucked Regina with her hand the way she liked. It was rough, hard and messy. Emma made mental notes for future reference as the Queen slipped her pinkie into the brunette's ass and she moaned loudly in response.
Emma felt the surge of magic building between all three bodies. She concentrated on pleasing the Queen instead of her own pleasure but it was too late. Her magic shot out of her wand, forcing the Queen forward, flat on top of her weaker counterpart and Emma shuddered and trembled as she realised the Queen had vanished and she was lying on top of her Regina. She quickly magicked away the shackles and pulled the trembling brunette into her arms.
"Hey, it's okay. She's gone."
Regina stopped shaking and sighed as she looked into her true love's eyes and shook her head.
"No, she hasn't, Emma. She's back where she always should have been." And she smiled wickedly.
