A/N: This is addicting! I'm loving seeing how many people read and enjoy my one shots. So here's another one for you. Watch out, this one definitely earns the M rating of this story ;)

"Come after me one more time, I'm coming back for the rest of this tree. Because sister, you have no idea what I'm capable of," Emma declared, levelling the Mayor with a challenging gaze.

Regina stood fuming. Not just at the vandalism but at the nerve of this woman to dare stand up to her. Everything about Miss Swan infuriated Regina: her abrupt manner, her disregard for rules, her insistence that she knew what was right for her son, the son she discarded as if he were trash as soon as he was born. And yet … and yet there was another feeling the blonde caused, low in her belly. A familiar tightening she had not felt in years, not even on the nights when Sheriff Graham kept her company.

Regina hesitated for a moment, looking intently into the striking green eyes before her. She was trying to read the younger woman's emotions. She saw anger, determination, challenging, and something else. Something the Mayor couldn't quite place.

A second later Emma gasped as her back made abrupt contact with the bark of the damaged tree behind her. Regina's hands landed either side of her head as she pinned the blonde to the trunk with her hips. Lips hovering millimetres away, Regina paused, offering the briefest moment for the blonde's protest. When none came, Emma found her mouth assaulted by the softest, fullest lips she had ever felt. The younger woman gasped, providing Regina with the opportunity to slip her tongue into Emma's open mouth. Caressing the other woman's tongue demandingly, an almost imperceptible moan left Regina's mouth as the heat between her legs increased.

Recovering from the shock of the situation after a few seconds, Emma brought one hand to rest on Regina's hip, the other fisting in short, thick locks pulling the brunette closer to her. She was not quite sure how chainsawing Regina's childhood tree had led to this but she was not about to complain as the older woman's hands moved to the bottom of her white tank top, slid underneath and moved up her taut stomach. Fingernails scratched at the pale skin before Regina's hand reached Emma's breasts and squeezed, then forced one cup down and pinched the nipple. Emma gasped and reached down to grab a handful of the Mayor's tight, round ass. Regina growled into Emma's mouth as she palmed her breasts roughly.

Dissatisfied with her limited access, Regina quickly pulled off the white tank top, reached behind Emma and released her bra clasp. Allowing herself a moment to stare at the small yet perfect breasts before her, Regina lowered her mouth to Emma's right breast, lightly nibbling the nipple before closing her mouth around it.

"Oh God," Emma moaned as she felt the Mayor's teeth graze her sensitive peak. She grasped harder at Regina's rear before sliding her own hands up to palm the older woman's fuller breasts. The bark scratching at her exposed back as she moved against the tree only fuelled the coiling sensation between her legs. Fumbling at the back of Regina's dress, Emma couldn't find the zipper. Huffing with frustration, the blonde gave up and reached for the hem instead. Pulling the material up to bunch around Regina's waist, Emma moved to cup the woman's sex. Through the lace panties, damp heat radiated against her palm, making the blonde smirk as she applied pressure to the area where she knew the Mayor wanted her.

Against the smooth skin of Emma's thoroughly licked, bitten, and sucked breasts, Regina moaned at the contact. Abandoning her pleasurable task, she stood straight and re-assaulted Emma's mouth, moving her hands down to fumble with the belt of the blonde's insanely tight jeans. Undoing the button and sliding down the zipper, Regina struggled to squeeze her hand down between the denim and cotton briefs. The wetness from the younger woman's sex could be felt through her panties, and Regina wasted no time pulling her hand back out and lowering it, inside the thin material. As her hands passed over soft curls, she felt Emma's own fingers pull the lace of her panties aside. Gasping as she felt the blonde's fingers pressing tentatively against her entrance, she slid her hand further down and flicked Emma's clit with the tip of her finger. Emma's head fell back against the tree as she moaned in pleasure, widening her stance to allow Regina further access.

Regina's fingers gathered more of the moisture from Emma's sex and began rubbing her hardened nub furiously. Emma leant against the tree, gasping as the rough ministrations between her legs sparked powerful waves of pleasure. Never before had she been so close to orgasm so quickly. Whether it was their exposed location, the crazy situation, or the infuriating woman whose fingers continued to skate quickly over her sensitive clit, Emma didn't know. All she knew was that she hadn't felt this good in a long time and she wanted to feel this every day of her life.

She felt the crest of her orgasm approaching embarrassingly quickly. Regina had reattached herself to Emma's nipples and was alternating between sucking and licking each breast. Remembering that her hand was still inside the Mayor's underwear, she attempted to distract herself by plunging first one, then two, fingers into Regina's opening. The older woman gasped, faltered momentarily, but then looked up at the blonde. Smirking as she saw undisguised lust in the green eyes looking down at her, Regina returned to laving the woman's nipple, redoubling her efforts to stimulate the blonde's clit. Tight, fast, hard circles over and over Emma's clit was too much for her and she cried out as her orgasm hit her. Slowing her fingers, Regina allowed Emma to come down gently from her high, smiling satisfactorily at the thoroughly fucked woman before her.

After a minute or so, Emma slowly began to remember where she was, who she was with, and where her fingers were. Quickly, she spun Regina around, the Mayor gasping as her back suddenly became the one scratched by the apple tree bark. Emma's fingers started pumping in and out of her at a blisteringly fast pace, angling inside Regina to hit a particularly sweet spot which caused a loud moan to fall from plump lips every time Emma hit it. Adding a third finger was all it took for Regina to come, her knees almost buckling as her body wracked with tremors. Emma moved her free arm to wrap around the older woman to keep her from falling to the floor. She slowed her fingers and finally pulled them gently from Regina's opening.

Stepping back when Regina was steady once more, Emma looked at the woman before her. Regina's hair was tangled and had bits of tree bark in it, her makeup was smudged and worn off. Emma doubted she looked any better. The Mayor looked sated, satisfied, and … something else.

"Erm, Regina?" Emma started, unsure quite what had just transpired and how to proceed.

Emma's words seemed to bring Regina back to herself. Standing a little straighter, she pulled her dress back down and ran a hand through her dishevelled hair. "You should leave Miss Swan," she said, a little shakily. "Yes, I think it would be best if you go now. Certainly from my garden, and preferably from Storybrooke."

"Are you kidding me?" asked Emma, incredulously, as she reached down to retrieve her bra and tank top. "You fuck me against a tree and then tell me to get out?"

"Momentary lapse in judgement, dear, nothing more. Now, if you'll excuse me, I have work to do." Regina pushed past Emma and headed back to her house, trying desperately to maintain her composure.

Dumfounded, Emma watched her go before she pulled her top over her head. Bending down to pick up the chainsaw, and an apple for good measure, she couldn't help herself but call after the retreating form of the Mayor.

"Regina?" Emma waited for the brunette to stop walking away before continuing. "You were right, I had no idea what you were capable of."
