[Now rated M]

The two women were in Regina's room in a matter of seconds after Emma practically carried Regina up the stairs. They were careful not to make too much noise as they ran past Henry's bedroom, giggling like two sneaky teenagers.

Just as they closed the door Emma attacked Regina's mouth hungrily, using her hands to unzip her blue dress and pull it over her head. The brunette didn't stay behind and started working the buttons of Emma's jeans with shaky hands, feeling the adrenaline taking over her.

"Nervous, Madame Mayor?" Emma mocked as she lowered herself to suck on Regina's pulse point, earning a loud moan from the brunette, who grabbed Emma by the back of her neck, encouraging her to kiss.

"This isn't the best time for, ugh, small talk, Ms. Swan!" Regina hissed as she arched her neck to give the blonde more space.

"I'll take that as a yes, then." Emma smirked as she kissed the brunette's lips once again and started unclasping her bra, taking it off and tossing it away next to the dress.

The blonde let go of Regina for a second to pull her own shirt over her head and struggled to kick off her boots and jeans, damning herself for choosing skinnies tonight of all nights.

Emma grabbed Regina by the waist and turned her around, leading her to the mattress and pushing her on top of it, their mouths never separating. She ran her hands over Regina's bare stomach, sending a shiver down the older woman's spine as she squeezed one of her breasts, taking her nipple between her fingers and pinching it gently

Regina arched into Emma's touch, encouraging her to pinch, to touch, to squeeze. She buried her hand in blonde locks as the other woman started placing wet kisses on her pulse point. The pool between Regina's legs was growing by the second, but one thing Regina Mills didn't do was beg, and she wasn't going to beg Emma Swan of all people.

Damn that blonde and her mind reading abilities. Just as Regina felt her arousal growing, Emma let go of her breast and used her now free hand to cup the brunette through her soaked underwear without warning, making her open her mouth in a silent moan and instinctively thrust her front into Emma's hand.

Emma smirked to herself when she noticed the effect she was having on the brunette. She decided to tease her for a while, make her pay for all the times she had pissed her off in the past. She didn't know what Regina would do to her later, but she decided she was going to take the risk anyway. Emma slowly rubbed her middle finger against Regina's throbbing clit, making the older woman bite her lip almost drawing blood. Regina just kept arching her back into Emma's touch, trying to give her the sign, and growing frustrated when the blonde didn't comply with her wishes.

The brunette had enough and grabbed a handful of Emma's hair, pulling it slightly in protest. Her action earned an annoyed 'ouch!' from the blonde, who grabbed the hand that was pulling at her hair and pinned it next to Regina's head, looking down at the other woman warningly. The brunette managed to give Emma a defiant glare despite the teasing finger that was rubbing at her clit just a few floors down. Their mouths collided almost instantly, both of them turned on by the other's challenging gaze. Emma let go of Regina's wrist to bring her hand to the brunette's cheek, stroking it tenderly. Regina whimpered quietly against the kiss as she put a hand on Emma's lower back and buried her face on the blonde's neck.

Emma knew that she couldn't keep teasing Regina for much longer if she wanted payback, so she yanked the brunette's panties down her legs and entered her with one finger, her thumb pressing against the other woman's clit as she rocked herself into Emma's hand.

"Ugh…" was all Regina managed to say as she held onto the headboard of the bed.

Emma watched in awe as Regina's features changed every time she slipped another finger inside her. The brunette's walls slowly started clenching around Emma's fingers, and Emma knew she was close. Regina buried her hand deep into Emma's hair as she felt her orgasm approaching.

"Emma, p-please…" Regina muttered against Emma's ear, her tone begging for release.

The blonde pressed a kiss to Regina's hair before nodding and thrusting hard and deep one last time. Regina moaned a little too loudly as she arched her body frantically into Emma's hand. She came undone with a quiet cry, her body falling onto the mattress as she panted heavily.

Emma waited until Regina came down from the high of her orgasm, brushing some of the brunette's locks away from her face and tucking them behind her ear. She removed her fingers, still buried deep inside the other woman, and directed them to her mouth, sucking them clean. Regina watched as she did so with hungry eyes, totally turned on by the action. Emma leaned down and thrust her tongue into Regina's mouth without permission, exploring the corners of the older woman's mouth.

Regina moaned against the kiss as she tasted herself in Emma's mouth. She dragged her nails down Emma's back and moved her hands to the blonde's upper front, using them to massage Emma's breasts, which were still covered by her bra. She received a moan from the blonde in response, who deepened the kiss and brought a hand up to caress Regina's cheek lovingly. The older woman shoved Emma gently, making her fall back on the pillow. She crawled to straddle her hips and leant down to whisper in her ear, sending a shiver down Emma's spine.

"My turn."

Emma swallowed nervously and she watched Regina kiss down her neck until she reached the middle section of her bra. The brunette dragged her hands across Emma's stomach to her back where she unclasped it, tossing it aside and releasing, the blonde's perfect rounded breasts. Her mouth was now dangerously close to Emma's nipples; pink, swollen and begging for attention.

"Regina…" Emma breathed, looking down at the brunette with half open eyes.

Regina understood immediately and wrapped her mouth around one of Emma's nipples and sucked gently, using her other hand to pinch the unattended one. She lowered her free hand down Emma's stomach and she reached the thin lace fabric of her panties, pulling them down the blonde's legs. She kept a hand on Emma's breast as she started lowering herself until her mouth was just above the other woman's heated center. Emma automatically lifted her legs and placed them above the brunette's shoulders, preventing her from moving. Regina held onto her legs as she started kissing the inside of her thighs, placing soft, wet kisses on the delicate skin.

Emma shook in anticipation as Regina started getting closer to her throbbing center, making the brunette smirk against her skin. She wanted to tease the blonde, just like she did just a couple of minutes ago, so she made sure to make the voyage through Emma's thighs painfully slow.

"Regina." Emma repeated firmly as she gripped the sheets tightly, sensing the other woman's intentions.

Emma sounded serious this time. Regina knew the blonde wouldn't be able to hold on for much longer, so she made one last act of teasing and blew softly against Emma's bundle of nerves before taking it fully into her mouth. She started sucking gently, sending vibrations through her body when she moaned at the blonde's taste. Emma tried her best not to scream as her eyes went over the back of her head, the pleasure Regina was giving her taking over her whole body. The older woman kept sending vibrations through Emma's center, making it even harder for the blonde to remain silent. She continued sucking on Emma's clit as she slowly lifted a hand to slide two fingers inside her all at once.

"Fuck, Regina." Emma panted with her eyes shut as she gripped the back of the brunette's head to keep her in place.

"You already did that, dear." Regina smirked as she placed a soft kiss on the blonde's inner thigh before dedicating her attention back to her clit, maintaining a steady rhythm as she thrust her fingers deeper inside her. Emma let out a breathy laugh despite the feeling of her orgasm approaching.

Regina felt Emma's walls clenching around her fingers after she slid a third one and started thrusting energetically. She continued spoiling Emma's heated center with her tongue at the same time, making the blonde see stars.

"'Gina…" Emma muttered breathlessly. "So close…"

Regina increased the speed on her hand as she pushed herself up until she was face to face with Emma. She used her thumb to press on her clit, thrusting her fingers in and out in a fast pace. She could hear Emma's quiet whimpers beneath her, and she watched the blonde as her orgasm approached, lowering herself to whisper in her ear.

"Come for me."

Just as Regina spoke, Emma's body shivered violently against her hand and she arched her back into the brunette's body. Emma almost let out a loud cry, but the brunette caught her mouth in hers just in time to stop her from screaming. The blonde kissed her back eagerly as she rocked herself against Regina's fingers, her walls closing tightly against them.

The brunette held Emma while she slowly came down from the high of her orgasm. The blonde laid back down on the pillow panting heavily, her hair plastered against her forehead, damp with sweat.

"Jesus Christ, woman." Was all Emma managed to say when she finally opened her eyes to look up at the brunette beauty staring down at her. "That was hell of a payback."

Regina smiled softly as she leaned down to press a sweet kiss to the blonde's temple, making Emma shut her tired eyes and sigh contentedly. Regina didn't say a word as she placed herself behind Emma, pulling the sheets over them and wrapping her arms firmly around the blonde's waist. She rested her chin on the blonde's shoulder as she traced lazy circles on her stomach and kissed her shoulder blade.

Emma smiled to herself when she felt the brunette spooning her from behind. She grabbed the hand that was caressing her stomach and brought her up to her lips, kissing it softly before wrapping it in her own and pulling it against her chest, just where her heart was.

"I don't want this to be a one night stand." Emma said quietly, afraid that if she said it too loud it would ruin the sweet moment between the two of them. "I don't want us to just forget this in the morning and go on with our lives like nothing happened between us."

Regina didn't seem like she regretted this, but Emma wasn't able to tell what would happen the next morning. She hadn't forgotten the heart to heart conversation they had earlier that night, but they also had had a few drinks and she knew Regina's mood swings all too well. She didn't want to wake up to someone who would look at her like a stranger.

"I don't want that either." Regina whispered, squeezing Emma's hand gently in reassurance.

Emma turned around in Regina's arms until she was facing her.

"Are you serious?" Emma whispered against the brunette's lips in disbelief.

"Emma, I told you that I had feelings for you." Regina rolled her eyes, letting out a soft smile. "I wasn't drunk. I wasn't just trying to get into your pants. I was being honest, and you know that's not something I usually do. So yes, I am serious."

Emma grinned widely as she grabbed Regina's face with both hands and placed a long, loving kiss on her lips. The brunette smiled against Emma's mouth and buried her hand in her blonde locks, pulling the other woman even closer to her.

"So... you could say I'm your girlfriend now?" Emma said when she pulled away, looking at the brunette expectantly.

"I guess you could say so." Regina said, her cheeks turning a pale shade of pink that didn't go unnoticed by Emma.

"Well then if I'm gonna be your girlfriend you'll have to be the little spoon." Emma stated with a serious look on her face.

"What?" Regina frowned.

"You're tinier than me. I feel like I'm being held by a chihuahua."

"I beg your pardon?" The brunette raised a skeptical eyebrow.

"Just turn around, Regina. It will be comfier for both of us."

"I might be your girlfriend now, Ms. Swan, but if you honestly think—"

Before Regina could protest again Emma caught her mouth in a kiss and shoved the brunette until she was giving her back to her. Emma took the chance to wrap her arms firmly around Regina's torso, making the brunette huff, but she didn't protest.

"Much better." Emma said before pressing a kiss to Regina's hair.

"You're unbelievable." Regina sighed as she settled herself against the blonde's front and shut her eyes.

"And you like me just that way." Emma smiled and rested her chin on Regina's shoulder comfortably before shutting her eyes. "Goodnight, 'Gina."

The two women started drifting off to sleep, closely snuggled against each other. The warmth of Emma's body lulled Regina to sleep, reminding her of the first night they had slept together in her office.

Just before Regina was completely out, Emma's sleepy voice broke the silence again.

"By the way, you're a lovely chihuahua."

.-.-.-.-.-

The next morning Henry practically threw himself at Emma when he saw her having breakfast in the kitchen with his brunette mom.

The two women had woken up an hour ago tangled in each other's embrace. It was the best sleep they had had in a while. It took Regina a good 10 minutes to get Emma out of bed, the blonde insisting on sleeping 'five more minutes, 'Ginaaa' with her face buried deep into Regina's neck. After taking a shower together –one that obviously involved some sexy times— Regina lent Emma the blue shirt Henry had sneaked for her some time ago, in hopes for her son not finding out his blonde mom had spent the night at their house. Regina knew Henry already suspected about their relationship, but she didn't want to make it even more obvious for the boy, trying to avoid questions and awkward moments between them.

Despite Regina's efforts, the shirt didn't fool him for a second. Henry was young, but he wasn't stupid. Again, he decided not to comment on it, but he wanted to play with them for a bit, so he asked Emma about it:

"Did you spend the night here?" Henry inquired as he sat next to her and poured some cereal into his bowl.

Regina sent Emma a warning look as she quietly sipped on her coffee.

"Uh, no, kid. I got here just a bit ago." Emma nodded.

"What for? Did you forget something?" Henry asked again, playing the innocent-ten-year-old-boy part perfectly.

"I, er…"

"She came to take you to school." Regina stepped in, seeing Emma struggling to find a good excuse.

"Oh… really?" Henry looked up at his brunette mother curiously. He actually hadn't been expecting that answer. "Why?"

"I'm running a little late for work and Em— Ms. Swan was available." Regina smiled. "So hurry up and finish your breakfast so you can go get your things and she'll drop you on her way to work."

Henry nodded energetically and dipped the last spoonful of cereal into his mouth before heading upstairs to get his backpack, completely oblivious to his previous truth game. He knew his time with Emma was always limited, and he didn't want to miss any second of it, especially when his mother seemed to be in a good mood.

Emma chuckled as she watched him leave so quickly. She walked over to Regina, who was leaning over the counter, and wrapped her arms around her waist, leaning closer to place a soft kiss behind her ear.

"Thank you for saving me there." Emma said quietly.

"You're welcome." Regina smiled, turning her head to peck the blonde's cheek. "We can't keep it from him forever, though. He'll have to know at some point."

"He probably knows already. " Emma shrugged, resting her chin on Regina's shoulder.

"He suspects, he doesn't know." Regina clarified.

"Whatever. We already acted like a divorced couple, I don't think he'll oppose to us being an actual couple." Emma grinned as she poked Regina's sides, making the brunette chuckle and try to wriggle away from her grasp. Emma made a quick move and turned Regina around, placing her hands on her hips to keep her in place.

"I'll see you later, Madame Mayor?" Emma smiled as she pressed herself to the brunette's front.

"I'll be waiting." Regina smiled before she circled the blonde's neck and pressed a soft, loving kiss to her lips.

Henry grinned from his hiding spot in the foyer where he had been watching his moms the whole time since he came down from his bedroom. Maybe Regina wouldn't need to plan a special explanation to tell him about her relationship with Emma; the boy was young, but he knew what love looked like, and his moms seemed like they were very much in it.

Fin.
