You were partners. Partners. And he was married. Married. There were so many fucking ethical reasons why you shouldn’t but damn it all, you did.
“I need your wire,” Agent Lenny Miller said over his shoulder as he sorted the equipment back into their cases. Your heart was still racing from the conclusion of your mission, your body was thrumming with adrenaline. You turned to face the hotel mirror and unzipped the back of your dress. When he was done with his brief task, Miller turned and after a moment of hesitation, approached you slowly. He clenched his jaw as he brushed the zipper away so that he could reach the mic-pack secured to the band of your bra. His pale fingers lingered an extra moment longer on the bare skin above and below the clasp as he pulled the pack off. He blinked his heavy eyelashes slowly, wetting his lips as he followed the wire up your back to your ear. His finger trailed over your skin, pretending to hold to the wire as his eyes glanced up to meet yours in the mirror. You removed the mic from your ear and turned back slowly to hand it to him. Miller looked down at you, still holding the pack, his heart racing too but his eyes deadly calm, keeping a level head just like a good agent would. Staring for a moment at the mic-pack, Miller finally exhaled slowly and nodded, taking the mic pack and wire. He switched the device off and looked back down at you again, face-to-face.
You were a young agent, fresh out of training with an expertise in languages. Agent Lenny Miller was a senior agent, a typical dark, brooding type with attitude issues and a soft-spot for intelligent women. He was always arrogant, but it was because he was always right. God, it was so fucking infuriating. When he wasn’t smiling (which was most of the time), you could barely make out the beginnings of crows’ feet at each outside corner of his eyes. He was in his mid-forties, married with a son. He wasn’t technically your boss but that didn’t make it any more ethical. These were just the things you told yourself as he continued to look down at you with his pale blue eyes.
He was standing with his feet shoulder-length apart and his jaw still painfully clenched. You reached around to the back of your dress and unzipped it all the way, your chest rising and falling quickly. Miller inhaled deeply as he saw what you were doing. Your black dress slowly slipped down your body to pool at your feet. He let himself look down at your body, covered only by your underwear. He stepped closer, just half a step, his lips falling open as he looked down at your lips. You rose onto the balls of your feet, offering your mouth but he inhaled sharply again and ran his hand over his mouth.
Miller stepped back and turned. He walked to an armchair in the hotel room and sat down on the edge of the seat, his hands steepled.
“Len-” you started but he held up a hand to stop you.
“Shhh, don’t ruin it, don’t ruin it” he whispered gently and looked you over again from the chair across the room. You stood silently in your underwear for a moment until you felt brave enough to move your arms to undo your hair. Your hair fell around your shoulders and you ran your fingers through it, picking out the knots quickly. Once that was done, you looked back at the man and asked him point-blank.
“Is it your wife?”
“Don’t ask me about her, Y/N.” He responded calmly, his hand still resting against his lips as he stared at you. You raise your chin slightly and inch closer until you're right in front of him. He looks up at you in appreciative silence, like he’s at an art gallery or the symphony. He lets you step between his knees and run your hands down the back of his head starting from the crown. His eyes close slowly and he sighs as your hands stroke his dark hair.
“If only you knew…” you whispered as your other hand slid down his cheek. Agent Miller’s eyes opened and he smiled softly, leaning into your hand.
“Know what?”
“How much I want you,” you answered breathlessly, your heart fluttering beyond beating. Miller chuckled in discomfort and inner turmoil. He shook his head and leaned back in the chair, out of reach of your hand.
“You know as well as I do that we can’t do this, Y/L/N.”
“Don’t talk like that.” You responded cooly, taking a step back as he watched you, his eyes helplessly trailing over your body. Miller leaned his chin against his closed hand, wetting his lips again as you put more distance between you. You could make out the half-hard bulge in his trousers that he tried to ignore. You two stared at each other for a minute on end, neither speaking as your eyes spoke to your individual desires. Finally, Miller sighed and reached out his hand, palm up and beckoning.
“C’mere.”
His voice was gentle but sure, as if there were absolutely no hesitation behind his request. You waited another moment before finally stepping back between his legs. His arms opened, inviting you to sit on his lap. You sat on his upper thigh, within the cage of his arms. Miller used his other hand to pull your legs across his lap, so that you were sitting completely across his legs like a child. His open hand rubbed up and down your thigh furthest away from his chest, slipping all the way down to your calf. You looked down at him and exhaled shakily.
“I-” he started but you pressed a finger against his lips, shushing him gently but firmly.
“Don’t ruin it.”
He smirked softly behind your finger and looked at your lips as you moved your head close to his. You dropped your finger and held the curve of his jaw instead, brushing your lips against his. The short stubble on his jaw tickled your fingers as you pushed them down his throat. His hand moved to hook around your waist and his lips fell open, responding to your tease. You exhaled shakily again, this time against his lips before finally kissing him. The kiss was so soft that your lips barely touched, barely moved. He looked up into your face, exhaling tightly before pulling you closer once again. You kissed again and just as softly as before. When you pulled away, you stared at each other in tense silence, the world around you was shrill like a static that separated you two from the rest of the world.
“Do you want to stop?” You whispered, looking between his blue eyes and his button nose. He briefly pressed a finger against your lips, dismissing your question, before kissing you again. His kiss was harder, stronger, as if he’d finally made up his mind without saying so: he was going to fuck you because damn it, he wanted you so badly. His teeth caught your bottom lip and you moaned against him as your fingers found the buttons of his collared shirt. The process was slow but expertly coordinated as if you already knew each other’s bodies as well as your own. You unbuttoned his shirt, slowly revealing his undershirt once each button slipped out of its eyelet hold. He wore the same undershirts that your dad used to wear beneath his dress shirts, the ones he wore to work, the similarity brought a strange sense of comfort as your hands felt the fabric beneath your hands.
Miller pulled you to straddle his lap so that you were completely facing him on your knees. You rested your butt on his legs, waiting patiently until his shirt and undershirt were completely removed. He held his arms over his head so that you could pull the shirt away from his bare skin. Agent Lenny Miller was by no means a largely muscular man, he’d left his field days behind him, but he was still fit, still lean and handsome. His arms were still muscular and you could feel the tension of his muscles every time he moved them around you. You sat back, ending your kiss for a moment so that you could look down at his bare chest. His pectoral muscles were tight and defined, his stomach shallow and taught. There was a dusting of freckles across his pale chest and a thin line of dark hair beneath his bellybutton. You pressed your hand against his lower stomach and felt the muscle meet your hand as it tensed. He laid his hands on the chair’s armrests and watched you with a calm expression on his face.
You slipped off his lap and opened his legs so that you could kneel between them. He ran his hand over his lips as he watched you, his eyes glued to you. You placed your hands on his knees and rose for a moment longer so that you could run your tongue across his collarbones. You dragged your tongue up his sternum, up to his throat, and ended at his jaw with a gentle nip. He shook once beneath you and groaned softly, so quietly that you barely heard it. When you returned to the place between his knees, his lips fell open in a helpless way, as if he were stuck in a trance. When his pants were undone, you ran your hand over his now-very-hard-cock and looked up into his eyes.
“Go on then,” he whispered, smirking softly as if he were joking. You smiled and pulled down his boxers just enough to find his erection. When it sprang free, he groaned audibly and leaned his head back for a moment. You rolled your tongue around the head slowly, relishing the taste of his precum, showing you just how much he wanted you too. Your hand gripped his shaft and squeezed gently, making him jerk his hips. He cursed beneath his breath as you moved your mouth farther onto his cock. You sucked softly, just wanting to prep him, not to make him cum. His hands tightened on the armrests, his nails digging into the red leather upholstery. You took his cock as far as you could without gagging and rolled your tongue before bobbing up and down.
“Ah fuck, girl. Slow, slow” he praised gently and closed his eyes as you sucked. When you could hear the distinct sounds of masculine whimpers, you stopped and looked back up at him. Miller exhaled tightly and ran his hand over your hair, fixing how it fell at the side of your face. His hand dropped to your shoulder and played with the soft skin there before pulling one of your bra straps off of your shoulder. You waited as he did the same to the other strap. He sighed as you stood slowly and stepped backwards towards the hotel bed, never used. Miller removed the last of his clothes and followed you slowly, his hand reaching out for your body. You let him pull you closer and kissed him as he felt for the clasp of your bra. He undid it easily and pulled it off of your arms so that he could feel your breasts. He nearly growled as he squeezed your breasts, feeling the hard nipple between his fingers. Miller picked you up easily and laid you back on the bed. He took your knees and pulled them apart so that he could stand between them. Still kissing you, he fit his hands beneath the bands of your thongs on your hips. His hands rubbed back and forth on your love-handles, in no rush to take off your underwear.
“Turn over, agent Y/L/N,” he muttered against your lips.
You nodded slowly, your lips starting to feel swollen and hot. You flipped over onto your stomach and felt his hands cup your butt before pulling down your underwear. He pulled them down your knees, over your calves, and off your ankles.
“Look at you. Good girl…” he whispered and tossed the underwear to the side. You pushed your butt up, signaling your need for him. Miller chuckled briefly in understanding and spread your knees again with his hands. With one of his hands, he feels over your wet cunt and leans over you to nip your shoulder.
When you moan he nods, “I know, I know. Me too.”
His long, rough fingers teased you cruelly as you bit your lip to keep from whining.
“Miller…” you whispered after a while of waiting and teasing. The senior agent smiled and leaned closer to your ear.
“Patience, girl. It’s an agent’s best virtue.”
You rolled your eyes and started to respond snippily before you felt him press against you, groaning. He pumped into you, hitting your ass with each quick gentle stroke. His hand that wasn’t being used to support his body went to your chin and pulled your head to lie flat on the side.
“How does it feel?” He asked.
“Hhha,” you tried to speak in a small breathless voice. He moved his hand back to your hip so that he could thrust deeper.
“Mmm fuck, you’re tight,” he panted and moved faster, harder. You cried out in pleasure and arched your back as much as you can beneath his body. “Tell me when you’re close.”
He groaned in pleasure as he found a good rhythm, your cunt gripping his cock better than his wife ever could. You moaned loudly, nearing yelling as he held you down and subjected you to the brutal honestly of his fucking.
He leaned down over you to rub his lips against your smooth upper back. He kissed your shoulder blade and slowed his thrusts, savoring the intimacy of your bodies. He moved his hips forward in a slow and flexed manner, straddling the line between climax and continuity.
“Good girl. Good. fucking. girl.” He muttered, his lips still barely touching your back.
“Shit I’m close,” you whined, your thighs shaking out of your control. As soon as the words left your mouth, Miller pulled out and picked you up by your hips. Nearly cradling you in his arms, he swapped places with you and placed you on top of his freckled upper chest.
“Sit,” he instructed calmly, “I’ll finish you off,” he gripped your thighs, waiting for you to move onto his face. You were panting and red in the face and it took a moment for you to realize what he was asking. With another reassuring nod from him, you shifted your body up and slowly lowered yourself down onto his face. You were skeptical and awkward until you felt his tongue glide over the lips of your sex. His nose rubbed against your clit as he sucked and lapped at your cunt. Your mouth fell open and your thighs immediately reacted by quivering. You placed your hands over his, still on your thighs, and cried out.
“That’s it,” his voice was muffled but still clear as he felt your orgasm building again, “I won’t stop you this time.”
Your body tried to jerk away from his mouth as your climax came on fast and strong but Miller kept you close to his lips. His arms didn’t let you leave even as you writhed from pleasure. You panted loudly, whining, until you finally orgasmed. Miller felt you orgasm against his mouth and waited until you had ridden it out before letting you pull away. You moved back enough for him to sit up. You were both panting and high on pleasure which made it impossible to speak. Miller looked you up and down, his way of asking if you were ok. You nodded softly and he nodded in return.
“You didn’t finish,” you observed breathlessly, straddling his lap as he leaned against the headboard.
“No?” He raised a brow, pretending to be ignorant.
“No, you didn’t.”
“You’re observant, good for you agent Y/L/N,” he responded evenly, raising both of his brows so that his forehead creased into that judgmental look he did so well.
“Fuck you.”
“Already did. Try again,” he tilted his head to the side slightly and nearly smirked. His biceps curled as he ran his hands up and down your arms. When you cocked your eyebrow back, calling him out on his bullshit, he sighed and resigned.
“That was for you, not for me,” he explained calmly, his eyes meeting yours.
“Making me finish, you mean?” You asked slowly, your brows furrowed more.
“Yes,” he nodded slowly and pursed his lips, “that was for you. I wanted to make you come.”
“And now what?”
“What do you mean?” Miller asked, confused.
“What do we do now?”
“We put on our clothes and go back to doing our jobs,” he answered with a half-hearted shrug. You scowled and shook your head.
“No.”
“No?” He repeated.
“You want this too, as much as you try to deny it and shame me for it. I’m not just a pity-fuck. Look me in the fucking eyes and say that you didn’t want me,” your voice dropped and you grabbed his shoulders, your fingers digging into his muscles. He held your gaze calmly but his heart beat faster. His jaw clenched and unclenched as he considered his response. Deciding against words, Miller grabbed the back of your neck and forced you into a hard kiss. You were caught by surprise and moaned tightly as he pulled you close and found your tongue to suck on, delirious with passion. His hands wrapped around you and flipped you over where you were then lying on your back beneath him.
“Fine, how’s this? I’ll look you in the eyes while I fuck you,” he growled and helped himself inside you. Like this, you could see his bright blue eyes as he held himself up over your body. He was already grunting and panting as he started to move back and forth. Both of your mouths fell open and you cried out in more pain than pleasure at this overstimulation. One of his hands wrapped around your throat, his thumb playing with the ridges of flexed muscles as you panted beneath him. His eyes only left you once when he dropped his head to your breasts to take one of your nipples between his teeth. He didn’t press hard, just enough to make you whimper. He flicked his large tongue over your breast, teasing the nipple with quick aggressive flicks. Your back arched and he growled in pleasure against your chest as he allowed himself to feel his orgasm. He returned his head to its original position so that he could watch your facial expression as he came. His mouth was open, his lips wet and pink. His cheeks hollowed everytime he panted, hitting your hips hard with his at the same time. He said nothing as he came, just slowed his thrusts, focusing instead on going as deeply as he could. His eyes closed and he shuttered, cumming inside you.
When it was over, Miller remained fixed above you, his grip loosened around your neck. He traced his finger up and down your throat in a strange show of affection.
“Alright?” Miller asked in a deep, heavy voice. You nodded and ran your hand over his chest.
“You?”
“Alright.” He nodded once. You stared into each others’ eyes, panting and exchanging hot breath.
“Alright,” you whispered.
Another moment of silence passed.
“Alright,” he repeated, staring now at your lips. Slowly, Miller inched closer. Slowly, your lips touched once more.
Alright.
