Major Sexual Content Warning
No One's POV
The trio tumbled into bed together, clothes and battle armor trailing a path from the garden to the bedroom, as Michael plastered himself along the lines of Erin's front and Lucifer pressed against Erin's back.
"Erin. Mate. My mate." Michael purrs in affirmation, pressing kisses to Erin's lips insistently as he thrusts against her hips, already steel hard and aching, dripping precum in the anticipation of taking what was his and bonding with Erin.
"Yours, Michael." Erin assures gently, weaving one hand through Michael's hair and scrapping lightly, drawing out a light moan of pleasure from Michael.
Lucifer suddenly growled, nipping at Erin's neck in displeasure at being ignored by his mate.
"Mine. My mate." Lucifer drops his voice into a low content purr like Michael, nipping again at Erin's neck for emphasis.
"Yes, I'm yours too, Lucifer." Erin replies patiently, shifting her neck to allow Lucifer more access as he continued to nip and place warm kisses, finally settling himself between her cheeks, thrusting in lazy contentment.
"Erin. Bond. Now." Michael demands, his grip around her hips tightening fractionally along with his wings.
"Yes, we can bond now, Michael." Erin assures, pressing a kiss to Michael's jaw and brushing light finger tips against the other side of his face.
Michael rumbles his assent at Erin's compliance, pleased that she has agreed to bond with him and submitted to his claim and dominance once more.
Erin was everything to Michael, just as Cassiel had once been. He would do anything for her, cross the parallels of the universes and worlds, fight Heaven's armies and go to the depths of Hell for her.
Her soul shined and burned like a thousand suns and stars in one, and by Father he never wanted to be parted from it in another millenniums. He would rather die or be cast out of Heaven.
"Bond. Erin. Mine." Lucifer whines, his voice becoming a high trill, almost anxious and worried, his wings wrapping around Erin from behind as his grip tightens around her just as Michael's had.
"Shhh, we can bond too, Lucifer." Erin assures Lucifer, one hand stroking a broad white wing to calm the Archangel.
Lucifer snuffles against his mate, rumbling deeply as he calms down, assured now that he can mate and bond too, the ache of the broken bond washing away by the pulsing of Erin's living soul.
"Mine." Lucifer rumbles quietly again.
Erin's soul was a beacon, it called to Lucifer like nothing else on Earth, Heaven, or Hell. It tethered him, guided him, and kept him steady and assured. She was the only reason he lived and fought. He never wanted to live without her again, the Pit would be preferable if so.
Erin smiled softly at her two Archangels, both of them pressed close to her, but not taking as they lay tangled in bed.
It was clear to her they were giving her a choice, even as desperately as they wanted her.
So different than the last time they had fallen into bed to bond, then again it had under different circumstances, and Erin didn't hold that against them. They were considerate, to a fault, not wanting to push her too soon or coerce her falsely. But their actions only made Erin more sure that this was right.
"Michael." Erin says, shifting her hips against Michael and widening her legs, allowing him to settle between her, a clear indication of her acceptance.
Michael growls, eyes darkening even more.
"Erin." Michael growls, sliding his length through the silken folds of her entrance to her core.
"Mmm. Michael." Erin hums, arching against him, enjoying the friction and movement of Michael's hardness against her aching core, though it was hardly an itch compared to what it could be.
"Erin." Michael growls again, thrusting harder, this time sinking his length into his mate's burning warmth, not stopping until he is buried to the hilt.
"Ah- fuck. Michael!" Erin cries, arching more as Michael stretches her with his length, her body clenching around him and accommodating his size.
Lips reconnect with lips Michael presses light kisses to his mate as an apology and distraction, his fiery red wings brushing warmly against her sides.
Lucifer moves next, lips trailing along Erin's neck as he presses deeper against Erin's ass, slipping between her cheeks to quickly find the outer ring of muscle and aligning himself.
"Erin." Lucifer hisses, pushing hard, the swollen head of his cock finally breaching the muscle of Erin's anal passage, the burning heat and tightness of Erin's body around the hardness of his member setting Lucifer's nerves on fire from pleasure.
"Shi- Lucifer!" Erin cries out, body arching almost unnaturally between Michael and Lucifer.
"I'm sorry, gorgeous. Did I hurt you?" Lucifer worries anxiously, nuzzling her apologetically, his lips pressing kisses to her neck and shoulder, and wings brushing against her comfortingly.
"Shh. I'm okay. Only startled me. Nothing to worry, Lucifer." Erin calms, managing to pull Lucifer's face from her neck to brush a hand along his jaw.
Lucifer purrs, pressing a kiss to Erin's lips before licking at her jaw and nuzzling her again.
Michael and Lucifer both stretch against Erin languidly, giving Erin time to adjust to their lengths and intrusion to their thrusts, content to remain settled in her body and feel the pulsing of her soul between them, their own graces humming with energy at the closeness of their mate.
"Michael, Lucifer." Erin hums, rolling her hips.
"Erin." Michael groans, voice dropping with lust and hips jerking against his mate.
"Gorgeous." Lucifer moans, digging his face into the crook of Erin's neck, breathe hot and needy as he presses closer to Erin's back, as if he could physically fuse himself to his mate forever, his member twitching and thickening with even more interest.
"It's okay, Michael, Lucifer." Erin promises, running fingers through Michael and Lucifer's feathers.
Erin's words were all Michael and Lucifer needed to hear in order to begin thrusting in earnest, falling into a firm rhythm with one another.
"Mmm. Lucifer! Michael!" Erin moans encouragingly, feeling both Lucifer and Michael press into her, filling her and stretching her to the hilt, bringing her pleasure and hitting nerves that had her seeing stars.
"Mine. My mate." Michael all but snarls, nipping at Erin's neck for emphasis as he presses into Erin's clenching, all-encompassing heat, thrusts becoming uncontrolled as his release swells and grace demands to re-bond with his mate.
"Yours, Michael." Erin chokes out, her voice thick with lust as her own climax mounts, pushed by Michael's surging, well aimed thrusts and body moving against hers.
"ERIN!" Michael finally shouts, giving one last punctuated thrust, filling his mate completely and sheathing himself in his mate's welcoming tightness, the head of his cock slamming into her cervix as he releases, flooding his mate with his own warmth, pulsing in hot, thick, reliving waves.
"MICHAEL!" Erin cries out, feeling her body tighten around Michael in reaction and release, nerves firing in pleasure as Michael's release crashes through her like a tidal wave, mixing with her own.
Blinding blue-white light suddenly fills the room, Michael's grace, illuminating Michael's wings as they flare wide, expanding to their full expanse.
"Erin." Michael says breathlessly, wings shuddering both with pleasure and this time hesitancy.
Unlike before, when Michael, Lucifer, and Cassiel bonded, because Erin was human (though admittedly they were bonding in Heaven), Michael or Lucifer's grace couldn't just automatically bond with Erin's soul even with the mating in place.
"Yes. It's okay. Bond us, Michael." Erin agrees, eyes lifting to look Michael's now blue glowing eyes, filled with his power.
Leaning to press a kiss to his mate's lips, Michael rumbles low in his chest, pleased with his mate's agreement as he pushes his grace towards Erin's soul, binding them together, a bond that would last for eternity.
Satisfied, Michael allows Lucifer to finish, rocking Erin back into Lucifer.
"ERIN!" Lucifer growls, pushing himself into Erin's passage one last time, seating himself fully and filling her with his own release, and feeling inexplicitly satisfied with himself for being the first to mark her this way as his wings flex broadly and shuddering in pleasure.
"LUCIFER!" Erin moans arching against him, body trembling slightly from Lucifer's thrusts and motion.
Fiery red and pure white wings settle around Erin once more, Michael and Lucifer easing out of Erin as soft feathers, caressing touches and warm, and affectionate kisses are pressed to her skin.
"Your turn, Lucifer." Erin murmurs, twisting to press a kiss to Lucifer's jawline.
"Bond now?" Lucifer murmurs back, his tone questioning as he gazes back at his mate, eyes dark with lust and mind only half rational.
"Yes, we can bond now." Erin reiterates, turning around fully to face Lucifer, and hands sliding over shoulders and through feathers comfortingly.
Lucifer groans, pressing himself closer to his mate, and length pushing at the slick opening of her folds, clearly seeking her warmth and tightness beyond.
"Erin. Mine." Lucifer growls, thrusting deeper, sinking himself into his mate's core without warning, stretching her around him as he sheaths himself completely and fully.
"Yours, Lucifer." Erin calms, widening her legs, allowing Lucifer to press deeper, the head of his cock hitting her cervix a moment later having her seeing stars and scrambling to find a hold.
Behind Erin, Michael purrs, thrusting his steel hardness against his mate, head catching the outer ring of muscle of her other opening.
"Erin. Mate. My mate." Michael purrs again, pressing harder, feeling the tightness and heat of Erin's passage consume him as he sinks in easily.
"Oh- Michael." Erin gasps out, rocking back into Michael's hips as Michael settles, bottoming out, hips flush against Erin's ass.
"Erin." Michael moans heatedly, lips pressing warm kisses to every patch of skin he could reach, practically mauling Erin's neck and shoulders.
This time, neither Lucifer nor Michael wait for Erin to grow accustom to their lengths, instead pulling out and all but slamming back in, setting an immediate rhythm.
"Fuck, Lucifer!" Erin cries out in pleasure, Lucifer setting a relenting pace.
"Almost there, gorgeous." Lucifer promises, panting hard and pressing a kiss to Erin's forehead, every nerve ending in Lucifer's body feeling like fireworks were being set off. Lucifer never wanted to stop, he never felt so alive like he did now.
"ERIN!" Lucifer practically howls, pushing harder with a thrust, his hands angling Erin's hips in a way that drives him deeper yet, pushing both himself and Erin to their climax, his own spilling out in strong, tidal waves of relief.
"LUCIFER!" Erin keens loudly, feeling her release swell and trigger, overwhelming her as it sweeps through her, Lucifer's member pressed tightly within her, head firmly to the opening of her cervix forcing her to take every bit of his own release.
Like his brother, the blinding blue-white light of his grace illuminated the room and highlighted his now fully expanded wings, as it sought out Erin's soul to bond with, Lucifer's broad wings trembling subtly from pleasure and nerves.
"Bond?" Lucifer asks again, nuzzling Erin gently.
"Yes, Lucifer. It's okay. Bond us." Erin agrees, looking Lucifer in the face, his eyes, though they were blue originally, equally lit up from his grace's power.
Rumbling lowly, the sound settles into a purr, Lucifer's wings flaring out wider as if he was presenting to his mate, Lucifer happily nuzzling against his mate's neck as he pushes his grace towards Erin's soul, his grace blinding as he binds them in a bond once more.
Lucifer's grace barely settled into the new bond, Michael pushes back, impatient for Erin to pay attention to him again.
"ERIN!" Michael growls, sinking deep into his mate's passage as his release crashes through him.
"MICHAEL!" Erin cries out, feeling Michael's release fill her in spurts and her own muscles contracting around him instinctively.
Shifting between Lucifer and Michael, exhaustion hitting full force, before Erin could actually express her exhaustion, both Lucifer and Michael ease out of her tired body, another moment later a flurry of action occurring; wings being swept around her, pillows being fluffed, blankets being drawn up, and bodies re-positioning as Lucifer and Michael settle around her, curling her between them protectively, encasing her in a protective nest of their bed.
"Sleep, gorgeous. You're exhausted." Lucifer hushes, his white wings resting over her and a kiss pressed to her cheek. "I love you, Erin."
"We'll protect you. Do not worry, love." Michael promises, brushing fingers lovingly down her spine, his red wings also resting over his mate. "I love you, Erin. Always."
"Hmm. Love you too, Michael, Lucifer." Erin hums contently, already half unconscious, another moment later letting sleep claim her.
