“Then you’re going to let them watch you fall from grace.” Emma gestured at the window in front of them, guiding Killian’s eyes to gaze out at the possibility of unwitting passersby spotting their activities, before taking him in hand once more. “You’re going to let them see you give all of yourself to a demon.” The guttural groan he made only spurred her on as she continued to pump him. “Unless you can’t handle it.”

Killian’s head fell back when Emma interrupted her stroking to grip his balls with a taunting squeeze, and he muttered under his breath, “God, forgive me,” as his eyes fluttered closed. Bucking his hips, he tried to coax her to go faster, “Yes, Emma, please yes,” but she smiled as she removed her hand and relished the whine that left his lips.

“An angel eager to sin.” She slipped her hands beneath the back of his trousers, kneading his ass for a moment before stripping off the leather, trailing kisses down his spine as she sank to the floor with the material. “Step.” With a tap to the backs of his knees, she removed the trousers completely and tossed them aside.

Emma ducked between Killian’s legs and twisted her body in one fluid motion so that she sat with her back to the window, greeted by his cock pointing right at her face.

“I want to taste you,” she said and lifted his cock so she could lick a slow stripe from base to head, swiping her tongue over the sensitive tip. Looking up at him from beneath her lashes, she cupped his ass and pulled him toward her as she took him into her mouth until he hit the back of her throat. The staccato sounds that left his lips convinced her to hold him there as long as she could, flexing her tongue along the length of him, until she had to lean back to take a breath.

“Delicious,” Emma sighed and took him in again, and again, this time guiding him back and forth, in and out, her tongue darting out to tease his balls with each plunge.

Killian panted her name amidst a slew of encouragements, lost in the way she licked and sucked and consumed him. Her grip on his ass tightened, and he bit back a moan when her finger made its way to the center and circled its find before dipping just barely inside.

“Ooh, sounds like you like that,” she parted from him long enough to tease, continuing her carefully intrigued prodding as she asked, “shall we sodomize an Angel of God?”

“It wouldn’t—” he gritted his teeth as she gave his cock a particularly strong suck, straining against the curtains holding him at her mercy, or lack thereof, “—wouldn’t be the first time, love.”

“Oh?” Emma raised an eyebrow at him, pausing for a moment before bringing him into her mouth once more, staring up into his eyes as he watched her intently.

“Aye. Though I much prefer to give than to receive.”

Of course you would, Emma thought, the pun of angelic nature not lost on her. She hummed her assent around him and sent a ripple of pleasure coursing through his body. 

It was too much and not enough. As Emma relentlessly devoured him, Killian fought against the material holding him back. With one forceful downward motion, he tore the curtains in half and freed himself as he sought his glorious ascension.

His fingers laced into her hair, and for once, he allowed himself to take. His frantic thrusts were met with surprised and hungry moans, the vibrations of which sent him soaring over the edge.

“Ohh fuck. Fuck,” he cried as he spilled himself down her throat. He felt it when she swallowed as he held her still and his cock continued to pulse.

“Such a dirty mouth for such a pure being,” Emma remarked as she caught her breath when he at last let her go. She got to her feet and stood facing him, using her tongue to trace the lines of the cross tattoo on his chest as she rose, and she yelped when he pulled her flush against him, his arms tight around her.

“Oh, it can be much, much dirtier,” he growled, making her gasp as he gave a harsh tug to her hair and attacked the exposed skin of her neck with sloppy kisses and less than gentle nips and searing hot breath. She arched up into him, and it was his turn to pin her against the glass. His hand and hook frantically tore at her blouse while his mouth continued its expert assault as it made its way to hers and along her jaw until he caught her earlobe between his teeth. “Would you like that, demon?” he asked, slipping his hand beneath her waistband and trailing his lips down to the swell of her breasts. “Would you like my mouth on you where you’re warm and wet and wanting for me? Teasing you as you’ve done me, making you long for my cock as much as I long for the feel of you around me?”

Emma suddenly couldn’t find the words, too caught up in the thrill of hearing him, an angel, her angel, talk like that. Hoping to get the point across, she threaded her fingers through the haphazard locks on his head and shoved him to his knees.

“Shall I take that as a yes?” he grinned, holding her gaze as he lifted her incredibly short skirt and ran his thumb along the already soaked strip of lace she considered panties before pulling it down to her knees.

Emma leaned forward to allow the remnants of her blouse to fall to the floor before reaching for the support of the window once more as he canted her hips toward himself with the curve of his hook pressed to the small of her back.

Killian’s wing curled forward to assist with holding up the material of her skirt, the feathers tickling the top of her thigh, so he could focus his efforts on her aching core. Too eager to taste her, he wasted no time, choosing instead to start right with his mouth at her clit. She jumped at the unexpected jolt of pleasure, and he steadied her with his hand splayed against her inner thigh, inching his fingers toward her center.

“How can you be from Hell when you taste so divine, Emma?” he praised. “I could spend eternity quenching my deepest thirst between your legs.”

“Then shut up and quench it,” Emma barked. She didn’t really mean it, not completely. She loved his silver tongue, especially when he used it to talk dirty, but right now she craved him putting it to a different use.

“Ask and ye shall receive.” As he gave one more suck on her clit, Killian plunged two fingers inside her, soon increasing it to three as he stretched her and coaxed out more of her arousal onto his expertly explorative tongue.

“God, you’re so fucking good at that,” Emma sighed, tugging his hair as she rode his tongue and fingers, relishing the warm vibrations his pained groans and hungry moans ghosted over her sensitive skin.

“Oh no, love,” Killian said without relenting, looking up at her as he continued working her between words. “Don’t blaspheme. I’m not Him. I worship at your altar, Emma, and there’s no better place to be on my knees.”

“I like your Word better, anyway.” Emma’s head tipped back as her hips began to buck, but her moment of near bliss quickly turned into one of frustration. “No,” she gasped, shocked and almost offended as he pulled away with a smirk and stood to his feet, leaving her clenching on nothing and far from sated. “Come on, Killian, please! I thought you were all about giving! And how is this worship?”

“I meant what I said, love. I adore you, I do. But I am an angel, after all.” Killian chuckled. “We tend to enjoy when someone is brought to the edge before they’re granted their salvation. I need you begging for it.”

“Fucking tease,” Emma huffed, turning away from him with her arms crossed in front of her.

“Mmm,” Killian mused, “perhaps you are ready to receive more.” He nudged her legs apart with his own, a soft blow with the side of his foot kicking one out to the side, and Emma scrambled to reach her arms out in front of her for balance, her hands slipping on the window as her legs spread. Snaking his arms around her, he set his chin on her shoulder as he held her in his embrace and mused, “What do you think, love? Shall we bare you to them as I take you and show them what they can’t have, or should we keep this sinful skirt on and show them how eager you are to be ravished by an angel?”

“On, off, I don’t care which you’re into, just fuck me!”

“A bit of both then.” Killian pressed the side of his hook to her stomach and pulled her to him, holding her so that her back pressed against his chest. Lifting the front of her skirt, he handed her the bottom hem. “Hold this up for me, love.”

With a smirk, she took it between her teeth, stretching the waistband higher and pulling the material taut between her breasts as she leaned her head back onto his shoulder and winked at him.

“There’s a good girl.” He smiled and raised the bit between them with the tip of his hook, taking himself in hand. “You pretend you like to rebel, but you behave so well for me. Now, tell me what you want.”

“I said, I want you to fuck me,” Emma answered, slightly muffled by her skirt, frustratedly trying to swivel her hips in the hopes of getting him inside her.

He draped her skirt over his hand and wrapped his hooked arm around her once more to still her. Her annoyance encouraged him to tease her all the more, and he brushed the tip of his cock between her folds agonizingly slowly as he said, “I need you to be more specific, love. What do you want?”

“Fuck, Killian, I want your cock inside me.” Emma almost dropped her skirt when he filled her in one smooth slide, her jaw instinctively ready to fall open, but she caught herself and clenched it instead, biting down hard on the material with a groan at the sudden stretch.

“Very good.” The tip of his hook dimpled her flesh, dangerously close to piercing her, as he held her against himself and slammed into her from behind. His fingers laced themselves between hers and he caressed up the side of her body as he brought her hand to rest on the back of his neck. Emma raised her other hand in kind, and Killian moved his to her breast, kneading and squeezing it as he lost himself in the feel of her.

“Fuck, you feel fucking amazing around me, Emma. Not even heaven compares to the feel of you.” Killian licked a stripe along Emma’s collarbone and clamped his mouth over the spot, digging his teeth into her flesh. She moaned at the thought of the mark she’d wear tomorrow.

Bringing his arm back, Killian pressed it across Emma’s shoulder blades, pinning her chest to the glass in front of them with an arch in her back that jutted her ass out at him, and this time Emma did drop her skirt as her mouth opened on a loud moan at the forceful change of angles. Killian grunted and tucked his hook beneath the waistband, ripping it apart with the sharp tip and watching it fall as he pounded into her.

“I told you to hold that,” he growled against the shell of her ear. “Perhaps you are a naughty little minx after all.” Killian swatted Emma’s ass with an open palm before grabbing the reddening flesh and massaging it, in theory to soothe the sting but so roughly that she thought he might leave a bruise if he continued, one she’d be more than willing to bear as a reminder of their time for several days to come.

“Forgive me?” she teased in a mocking tone as she met his thrusts with each backward roll of her hips, almost inclined to make prayer hands at him if moving them wouldn’t risk her falling.

“Not exactly a sincere repentance, is it, love?” Killian struck her ass once more before grabbing a fistful of her hair and tugging her head backward. “But it is rather tempting to grant you reprieve nonetheless.”

“Ah, so why don’t you give into that temptation, angel?” Emma gritted.

“Don’t try to persuade. Ask me for it.”

“Please, Killian, I’m so close.” Emma couldn’t take it anymore. “Make me come, angel. Please!” Emma sighed through a string of curses as Killian moved the curve of his hook to her clit, pressing the brace against her flesh just above it as he rubbed quick circles over the swollen nub.

“What say you, demon?” he asked, breathless himself as he brought them both to the brink. “Shall we chance our own breed of Nephilim?”

“Yes please,” she panted desperately. “I’ve already tasted you. I want to feel you. I want to feel you come inside me.”

“I’ll give you what you want, demon, but I want to hear you scream my name when I do, not God’s.” Killian’s mouth travelled from Emma’s neck to her shoulder and back as he pistoned his hips with abandon. His teeth scraped her flesh before he moaned against her cheek as he found his release, “Emma, fuck yes, Emma,” filling her with it and pushing it deeper as it dripped down the length of his cock.

With his brutal thrusts and relentless teasing, Emma granted his request soon after, crying out, “Killian!” at the top of her lungs as her knees buckled beneath her.

He practically lifted her off the ground when he caught her with his arm wrapped around her middle, holding her tightly as he drew every last drop of ecstasy from within her before he slipped from her core and spun her into a lightheaded kiss, caging her against the window with his arms once more.

“Well, that was fucking hot.” Emma smiled against his lips as she pulled one into her mouth to bite it playfully, her chest heaving as she struggled to catch her breath. “Who knew you had it in you, angel?” One hand anchored in his hair as the other clutched at his ass, and she pulled him closer to her so she could rut against his leg, letting their releases spill down her thigh onto his and making him groan.

“It was the other way around, love,” he joked with a certainly devilish smirk, “but I concur, it was fucking hot.” Tucking his arms beneath her legs, Killian hoisted Emma into them and carried her to the bed, tossing her not so gently onto the mattress.

Emma giggled as she taunted him with one curled finger, beckoning him to her as she spread her legs wide, an invitation he happily accepted as he knelt between them and crawled above her body with a guttural growl.

“You might just convince me of the divine benefits of your side,” Emma purred, running her hands down his sides to grip his waist, “but I think I need to witness a bit more firsthand to make sure I believe, if you’ve got another miracle in you.”

“Angels are eternal, darling,” he said. “I’ll never leave you if that’s what it takes to really fill you with the spirit.”

“Promise?”

“Promise.”
