Disclaimer: I don't own Castle, nor am I one of the shows writers.
A/N: If you're reading this, it must mean I did a good enough job in my description to catch your attention. Now for the information you should probably know. Yes, I realize Esposito is probably a little OOC. I would picture him being more disgusted than intrigued, but this story doesn't happen without it and I think Espo is more likely than Ryan. Any and all mistakes are my own.
Now that's all out of the way. Enjoy the smut.
Detective Javier Esposito watched through the two way mirror as uniforms escorted Marcos Hernandez out of interrogation room one and his partner Kevin Ryan followed them out before walking across the bullpen to the elevator to get their late lunch. He shook his head, wondering to himself what could drive a young man with everything going for him to throw his life away by murdering his best friend to impress a girl.
Several minutes after the unis had taken the young man back to lock up, Esposito was still standing in the observation room collecting up the case files and putting them into a box for storage until trial.
He jumped in surprise, spinning around to face the window into the interrogation room as the door slammed abruptly open, his eyes widening in shock as Castle pushed Beckett into the room, the man's hands already on her shoulders, pushing her jacket down her arms and letting it drop to the floor, and their lips fused together.
"Castle, we have to make this quick. The boys will be back to question Hernandez any time now." Beckett panted against Castle's lips as she ran her hands up his chest to grab his lapels, pulling him closer to her before her nimble fingers began to work their way quickly through the buttons of his shirt.
"What the…" Esposito mumbled to himself, his eyes widening in shock as he watched his boss work determinedly at the writer's shirt. They must not have realized that we decided to question Hernandez before lunch instead of afterwards. He watched through wide eyes as Castle removed Beckett's shirt and attacked the pulse point on her neck, nipping and sucking, causing her to gasp a small intake of breath.
"I swear I will shoot you if you leave a mark Richard Castle." She warned him breathlessly, causing Castle to chuckle against her heated skin.
Espo shook himself slightly as he forcefully tore his eyes away from the sight of Beckett's chest, covered only by her black lace bra. "Get it together man, she's your boss!" he muttered to himself. But man is she smokin' his subconscious reminded him.
On any normal day Javi saw Beckett as a boss and friend, sometimes even as a sister. While he had always known she was beautiful, he didn't think much of it on an average day. But this, today, wasn't an average day, and watching his half naked boss writhing under her lover's hands was cause for Esposito's blood to run south.
Seeing her now, as Castle reached behind her to unclasp her bra and leaned down to suck a hardened pink nipple into his mouth, rolling it under his lips and nipping lightly with his teeth, Esposito saw his boss in a totally different way. He saw her as a woman with an amazing body who was half naked in front of him, with no idea that he was watching. He couldn't stop is body from reacting, even if he wanted to.
A soft moan from the other side of the glass brought Esposito back out of his head as he watched the couple back away from each other to quickly remove their own pants. Espo was less shocked this time when he felt another jolt in his groin at the sight of Beckett shimmying her skin tight jeans down over her ass.
He groaned in frustration at himself for getting turned on watching his boss and her writer crash back together in a tangle of heated skin and wet seeking mouths, now only in their underwear. He was just about to turn to leave them to it and go take a cold shower when his eyes nearly bugged out of his head as Castle reached out and simply tore the lacy scrap of panties from Beckett's body.
"That was my favorite pair." She growled under her breath at him as Castle looked back at her unapologetically.
"I'll buy you another" he replied, eyeing her body in appreciation and longing.
Kate tried summon her inner Detective Beckett to give Castle a glare that would make him fear for his life, but the way the man gazed hungrily at her body made her go weak in the knees and she knew he wasn't effected the way he should be. With a huff she launched herself at him, shoving his boxers to the floor, where they pooled at his feet, and freeing his impressive length. She palmed him roughly, hearing him groan as she sank her teeth into his shoulder as punishment for destroying her underwear.
Esposito flinched in sympathy for Castle as Beckett bared her teeth, but damn if that boy wasn't impressive. He could see why Beckett couldn't keep her hands off him. I wonder how long this has been going on… Espo thought to himself, the realization hitting him that this isn't their first time.
His attention was once again drawn to the now naked couple in the room as Castle lifted Beckett onto the table and pushed her down onto her back, her hips at the edge and her legs dangling towards the floor. He quickly kneeled and pulled her legs up onto his shoulders on either side of his head, causing Beckett to gasp again as he ran his hands from her ankles up to her thighs, spreading them wide and inadvertently giving Esposito a look at her nether region, already glistening with moisture.
Wow, he hasn't even touched her yet. No wonder they're getting it on in the interrogation room. Esposito finally gave in, unzipping his fly and pulling his semi hardened length out into the cool air as Castle went to work between her legs, pulling sounds from Beckett that quickly had Esposito rock hard and ready to go.
Apparently Espo wasn't the only one ready to go, as Beckett's moans increased in volume steadily and her back began to arch off the table.
Castle placed one hand on her stomach, holding her in place as he sank two fingers of his other hand into her while working his tongue expertly over her clit.
Feeling his fingers slip into her core so easily, Castle felt himself harden instantly.
"You're so wet. I love that you get like this for me Beckett."
"Only for you Castle. Only for you." She panted above him.
He continued thrusting his fingers in and out of her, hearing her quiet moans and whimpers. He knew just what he was doing to her and that she was getting close. Knowing just what she liked, he curled his fingers inside her, stroking the rough ridge along the front wall of her wet heat.
"Let go Kate, I've got you." He growled against her as she writhed on the table in front of him.
He pushed a third finger into her molten core and sucked her clit into his mouth, biting it lightly with his front teeth as she ground against him.
"God, Castle…" Kate groaned as he bit down and she couldn't hold off her orgasm any longer. Her back arched off the table as liquid fire raced through her body, the blood in her veins singing, as all sensation focused on that small bundle of nerves in her lover's mouth.
He continued pumping his fingers in and out of her to prolong her orgasm and then to work her down from her high slowly before withdrawing completely, leaving her panting on her back on the table.
Beckett sat up as she caught her breath before eyeing Castle hungrily and stalking across the interrogation room to where he'd relocated near the mirror. He gulped at the look in her nearly black eyes as she reached him and dropped to her knees.
Esposito pumped his cock in his hand as he watched Beckett coming on the table under Castle's skillful ministrations.
His eyes widened as, moments later, his boss sat up and hopped from the table, only to drop to her knees in front of his friend. Just on the other side of the glass, and she took his length in her hand, pumping it once, twice, then rubbing her thumb across the tip to spread the drop of pre-cum that had formed.
Espo watched her in awe, unconsciously repeating her movements on his own cock in his hand. Echoing Castle's moan as she took him into her mouth and swirled her tongue around him, coating his length in moisture as she took more of him into the warm, wet cavern of her mouth.
Esposito imagined it was his own cock that Beckett had her lips wrapped around. Stroking himself faster, he watched her throat convulse as she appeared to swallow the other man whole.
"Kate…" Castle groaned loudly and tangled his hands into her hair, pulling her off his cock with an audible pop. "You're going to be the death of me woman" he growled as he pulled her against him again, fusing his lips to hers.
Beckett felt Castle's hard length pressing urgently against her inner thigh as his tongue slid along the seam of her lips, asking for entrance which she gladly gave. He quickly pushed his tongue into her mouth to duel with her own.
When air became a necessity she pulled away from him, once again gasping for breath.
Grabbing her hips, Castle spun her around and pushed her up against the cool glass of the mirror, planting his thigh between her legs and parting them wider before grabbing his cock in his hand and rubbing it up and down her wet slit.
"Castle, please!" Beckett cried out as he paused at her entrance and placed just enough pressure on it to slip the tiniest amount inside her. She cursed him internally and whimpered as he pulled back away from her and continued rubbing himself through her slick folds.
"Castle! I need you in me… Now!" she begged. Beckett actually begged!?
"As you wish Detective." Castle smirked, leaning his chest against her back and pushing her own into the glass. Her nipples pebbling against the cold, smooth surface. She turned her head to look into his ocean blue eyes, speaking without words, letting him see the need in her own hazel orbs.
Castle leaned forward and pressed his lips to hers tenderly. He felt the puff of hot air on his lips that escaped her mouth as he pressed slightly into her with his movement.
"Ri-ick!" she gasped as he thrust into her in one smooth, swift movement, his lips crashing against hers in a clash of teeth, lips, and tongues.
"God Kate, so wet, so tight." For a bestselling author, Castle couldn't have formed a complete sentence at this time if his life depended on it.
He paused for a moment, allowing her body to adjust to his size, but Beckett had other plans. She opened her eyes that had slammed tightly shut the moment he entered her and smirked as she met his gaze. Baring down, she clenched around him, making him groan and grab her hips.
"You have to stop that or this is going to end before it even begins." He warns her breathlessly. She winks at him and clenches again. "What's the matter Ricky? I thought you liked it when I was in control."
Castle slams his eyes shut and takes a deep breath in and lets it out as he controls the urge to explode inside her then and there. "You are an evil woman Katherine Beckett." He grits out through clenched teeth.
Esposito's hand stills on his cock as he stares at his boss's nipples pressed against the glass in front of him and he wants nothing more than to take one of the hardened nubs into his mouth. As Castle begins moving, thrusting in and out slowly, Javier begins to stroke himself again, matching the rhythm of couple on the other side of the mirror.
He continues to watch them, speeding up as Castle begins to pump in and out of her faster, thrusting harder. The sound of their ragged breathing filling the room. "I'm going to Hell for this." He mumbles to himself under his breath as realization dawns on him that he is actually getting off on watching two of his best friends having sex and they don't even realize that he is there. What do they expect though, doing this in the precinct? His subconscious fills in for him. The same corner of his brain that is still attentively watching as Beckett's body rocks back and forth against the mirror as she counters each and every one of Castle's thrusts, their naked skin slapping together, creating obscene sounds.
Putting the morality of what he is doing out of his mind once again, Esposito watches his friend grab his girlfriend's left breast in one hand, pinching and rolling the nipple between his fingers. The other hand slithers down her body, pausing over her stomach to circle her navel, before continuing down, down, down. Past her neatly trimmed mound and between her drenched lips to find the small nub of her clit.
Beckett cries out as his fingers find her pleasure center and press against it urgently. He's not taking any prisoners as he pushes into her harder, clearly beginning to have trouble holding himself back.
At her cry, Esposito takes a step closer to the window and fondles his balls in his left hand, his right still stroking himself in time with the thrusts of the couple on the other side of the glass. Groaning as he feels himself getting close to his own release and reaching quickly for a tissue on the table next to him so he doesn't create a mess that he would never be able to explain.
"Don't stop Castle! I- I'm getting close."
He watches as Kate's eyes slam shut and her entire body tenses.
Castle pushes his thumb down on her clit rhythmically and changes the angle of his thrust slightly to graze against her G-spot.
"Come for me Kate." He whispers in her ear, his hot breath tickling the skin on her neck and his words enough to send her over the edge.
Castle reaches up to clamp his hand over his girlfriend's mouth to stifle her gasps and moans as her inner muscles clench and flutter powerfully around him, pulling his own release from his body. He continues to thrust as he empties himself into her, helping prolong both of their orgasms until he collapses against her back, spent. Neither of them realizing their friend, Javier Esposito just came, right along with them, mere feet away, on the other side of the mirror.
Esposito finished cleaning up and tucked himself away back into his boxers, zipping up his pants. He looked up as the writer pulled out and away from Beckett. A whimper escaped her mouth at the his retreat from her body and he turned her around, kissing her softly and pulling her close to him before both separated and began to redress themselves.
During this time, Espo realized he needed to get back to his desk so as not to get caught and he turned to grab the box of files from the table. He stopped mid-turn, gasping as he saw the small red light blinking on the equipment against the wall. The camera in the corner of the interrogation room was still recording.
"Shit" he grumbled to himself before turning the camera off and hurrying back to his desk, not looking up from the paperwork that he had quickly pulled out when Castle and Beckett emerged from interrogation one, looking much more put together than they had moments before.

"Bro, I need you to do something for me." Esposito told Ryan later that afternoon once the Irish detective had returned from lunch and the dynamic duo had gone out to follow up with the dead girlfriend's parents and let them know the bastard that killed their daughter had been caught.
"What is it?" Ryan asked, suspicious of the tone in Esposito's voice.
"I need you to go back to the video from our interrogation earlier and delete part of it."
"What? Why would you need me to do that?" Ryan asked, confusion clouding his normally clear blue eyes.
"After you left, Mom and Dad used it for a little alone time and the camera was still rolling." Esposito said, even quieter than before giving Ryan a suggestive look, hoping he understood what he meant while leaving out his own part in what had happened.
"They were- you don't mean… They were getting it on?" Ryan nearly squealed in surprise.
"That's exactly what I mean, bro. I don't think Beckett would appreciate that being played when this thing goes to court. She'd skin someone alive." They both cringed at the thought of what their boss would do if this thing ever saw the light of day.
"Alright, I'll take care of it. How long do you think they've been together? Man, how could they keep something this big from us?" Ryan asked trying to pinpoint a time in recent history that they had seemed different.
"I don't know, but we need to find out. I want to know who won that pool." Esposito murmured thoughtfully.
"I think I have an idea. I'll take care of everything." Ryan replied before turning to his computer to get to work on removing the video.
When Castle and Beckett returned from visiting the Vic's family the boys were already gone for the night. Beckett walked to her desk and collapsed into her chair with a sigh, glad the long day was finally coming to an end. She just had to finish up some paperwork and she could go home and relax with her boyfriend and a nice glass of wine.
"Beckett, what's this?" Castle asked picking up a cd in a thin plastic case off the edge of her desk. On the case was a note that read, 'This is the only copy in existence. You can thank us by letting us know when this started. Everyone has a lot of money riding on you two.'
Taking the cd from his hand, she read the note and shrugged. "I have no idea and I'm too tired to deal with their little games right now, we can check it out later once I'm curled up in front of a nice warm fire for the night with my man." Beckett replied, placing it in her bag and giving Castle a warm smile.
"Besides… the sooner we get out of here, the sooner we can have a repeat of this afternoon." She grinned at him impishly before turning to finish her paperwork, leaving Castle staring at her slack-jawed.
Little did they know just how accurate that statement was.
A/N: I hope you enjoyed the story and would like to hear what you thought. As it stands, this story is completed as a one-shot. I have some ideas floating around in my head of possible other chapters with Ryan's reaction as well as Castle and Beckett's but I'll wait to see how my first story is received before deciding whether or not to write more.
