Patrick Jane felt jealousy sizzle up inside of him as he watched his little minx of a boss and girlfriend outwardly flirt with Haffner, flashing that cute smile that's supposed to be reserved only for him and flipping her ebony hair back to reveal the pale column of her neck.

It sparked him with rage. He wasn't typically a man of anger, but seeing Teresa Lisbon with another man brought it out of him. He was holding onto his tea cup so tight as his eyes narrowed at the two standing in her office, forcing himself not to barge right in there and escort Haffner out.

Thankfully, Haffner exited her office a minute later, leaving Lisbon alone at her desk, unaware of her consultant's blazing jealousy. She dove into a pile of paperwork and Jane stood up from his couch, clearing his throat before heading towards her office, making sure to shoot Haffner a glare on the way.

He pushed the door of her office open and let himself inside, shutting the door softly behind him. Lisbon's head snapped up at the sudden sound, her eyes locking with Jane's.

"Hey Jane," she greeted, not having the slightest idea of how angry he was. "What's up?"

He didn't respond for a moment, just let his eyes ravage her face. Big, emerald eyes that always managed to tug on his heartstrings. Freckles dotting across her small nose and cheeks, forming a path along her throat until they disappeared underneath her blouse. Small, pink lips that were begging to be swallowed by his own. God, she was the most beautiful thing he'd ever seen.

"Jane?" She repeated, snapping him out of his trance. "You okay?"

He blinked twice before coming up with the words to speak. "Actually, I'm not okay."

Her eyes immediately grew concerned. "Why? What's wrong?"

He almost let a chuckle slip. Naive she was, his little Teresa. She truly had no idea what she'd done.

With a neutral expression, he walked around her desk and spun her chair around to face him. Luckily for him it was late and nobody else was in the building, so he was allowed to do whatever he wanted with his little princess. She just didn't know it yet.

"What's going on with you and Haffner?" He asked, keeping an innocent tone. His eyes lashes fluttered as her brows furrowed in confusion.

"Haffner? There's nothing going on between me and him."

"Really?" He scoffed. "Because if I recall correctly, you had just been flirting with him."

"What?" She spluttered. "No I wasn't."

"Don't lie to me, Teresa. You were all over him. A little minx you are. You're very good, I'll give you that."

Her lips were slightly parted, looking like she wanted to say something else, but she didn't have the words. She just stared at him with those doe-like eyes, slowly being swallowed by blackness. He was sure his pupils were dilated now as well.

He bent down to her level, his lips so close to hers his breath fanned her face. He smelled like tea, mint, and Jane, and she almost sighed in happiness, but stopped herself.

"I wasn't flirting with him," she finally managed to get out, her voice hoarse. She wanted to reach out and touch his face, particular his blonde stubble or his luscious lips. "I was just being friendly to get information in a case."

He hummed, wrapping a dark curl of hers around his finger. His lips ached to kiss her, but he held himself back. He would kiss her soon, but for now, he needed to prolong the foreplay.

"Well, my dear," he started, his voice dark and full of lust, "he really bought it. I could see him undressing you with his eyes. He was practically eye-fucking you, and I must admit, I wanted to punch him in the face."

"He was not," she deflected, but her voice was small and he could tell by the look in her eyes that she didn't believe her own words.

"He was," he murmured, resting a hand against her cheek and brushing his thumb along the satiny skin. "Sucks for him, because you are and will always be mine."

With that, he smashed his lips against hers, knocking the breath out of her lungs instantly. A groan escaped his throat as her soft lips danced with his, so delicious and perfect. His tongue pressed against the seam of her lips, begging for entrance, and she opened for him eagerly, allowing his tongue to sweep in and claim her mouth.

His fingers delved into her hair, massaging her scalp as he deepened the fevered kiss. A tiny moan flitted into his mouth and his entire body perked, some parts more excited than others.

Their lungs burned for air, the only reason why they pulled apart, their lips red swollen, their eyes hazy with lust. Lisbon's head was spinning and she could hardly think straight while Jane just stared at her in a daze.

"Wow," he breathed, his eyes half-lidded. "Every time I kiss you I become addicted all over again. You're like a drug."

"So are you," she said breathlessly, her chest heaving. His eyes peeked down her blouse and he immediately had to look away before the lower half of him became more painful to keep in his pants.

He wasn't done with her. He couldn't be. She was right there in front of him, looking so small and beautiful, there was just no way he could walk away and act like nothing had happened. He needed to finish what he'd started.

"Teresa," he whispered sensually, looking deep into her green eyes, practically pouring his soul into them. "I need you."

The confession made her blink, and he found her bewilderment adorable. He honestly had no idea how he lasted so long without touching her, kissing her. Now that he knew the way she tasted, he was never going back.

A few seconds tick by, then, softly, she asked, "are you sure?"

"I've never been more sure of anything in my life."

The sincerity in his sea-green eyes was enough to convince her. She quickly stood up, grabbed his hand and escorted them both out of her office and up the staircase, taking them to the basement where he practically lived.

They stumbled inside and Jane was quick to shut and lock the door, just in case someone tried to get in, albeit there being no one at the CBI. He fumbled with his clothes, shredding his vest and shirt while Lisbon discarded her blouse and pants with such agility and confidence.

When he looked up, his mouth fell dry.

There in front of him was his Lisbon, clad in nothing but a black lace bra and matching underwear, the perfect contract to her pale white skin. Her breasts were small, just big enough to fill his hands, and he could see her nipples poking through the fabric of her bra, eager to be touched and played with. Her legs went on for ages, freshly shaven and looking as soft as silk.

Fuck, she was going to be the death of him.

"Teresa..." He trailed off, his eyes still taking her in with awe. He was shirtless now, wearing only his boxers, and he could see the hunger in her eyes, like a predator waiting to catch its prey. It turned him on almost painfully.

"Patrick," she echoed his seductive tone and made a hook with her finger, beckoning him forward like the authoritive figure she was. She called the shots like always, and he was perfectly okay with that.

He stepped closer towards her, greedily sucking air into his lungs so he didn't forget to breathe. Reaching out like a little boy, he embraced her, her head fitting perfectly beneath his chin, his fingers caressing the small of her back until a dreamy sigh escaped her lips.

"You are so beautiful," he murmured into her hair, his fingers brushing over the clasp of her bra. It took him less than a second to undo it, the straps falling off her shoulders and exposing her small yet firm breasts.

He pulled back and feasted on them with his eyes. Her tiny nipples were rock-hard, and his lower half stirred again.

He couldn't hold back any longer. He greedily lunged forward, ducking his head to her breasts and sucking one of the pink nubs into his mouth, earning a moan of approval from her. The sound only egged him on, and his tongue flicked over her nipple, savoring the way her skin tasted.

"Please," she whispered, and the word was his undoing.

He hoisted her into his arms abruptly, grinning when a surprised shriek left her throat. He carried her over to his desk and made room before setting her down, her enticing legs dangling over the edge, her lips pouting as a silent plea to be kissed.

He happily obliged her, dipping his head to connect their lips in a passionate kiss. He couldn't remember the last time he'd felt like this, his head clouded with lust and thoughts of her, his woman, his life, his everything. He would do anything for her, he knew that for sure. He would do whatever it took to make the love of his life happy.

Their tongues battled but neither of them won, and even while they were kissing it was clear they didn't leave competitiveness behind. But Lisbon had forgotten that he had tricks up his sleeve, and he could make her come undone with just a touch.

He decided to prove his point. One of his hands began travelling down her body, caressing her breasts, her navel, and then the skin just above her underwear. He smirked when he felt her shiver beneath his gentle touch. Oh yeah, he was going to have fun playing with her.

His fingers dipped just slightly beneath the band of her underwear, brushing along her soft mound. She started to squirm on the desk, shaky breaths leaving her parted lips.

He smiled lovingly at her. "You're a beautiful mess, Lisbon. You look so perfect like this, perched on my desk, silently begging to be fucked mercifully...we both know you won't beg with words, you're too stubborn for that, but I'm sure I can make you writhe and squirm until you're crying, begging me to take you. Do you want that, my love?"

"Yes," she breathed, her back arching into his touch. His fingers remained in place, unmoving, leaving the most sensitive part of her untouched, much to her displeasure.

"Hmm..." His thumb suddenly flicked over her clit, making her jolt with need. "On second thought, I'm not sure if I want to fuck you after all. You've been a very naughty girl, and you know what happens to naughty girls, don't you?"

Her mind was on overload. She barely had the strength to talk, too focused on his hand in her underwear, but she managed to get out, "no, I don't."

"Well, allow me to enlighten you." He leaned forward, brushing his lips against the shell of her ear. He lowered his voice to a particularly husky tone. "Naughty girls don't get rewarded. They get punished."

His words sent her body on overdrive. A spark of excitement seared through her and she tried to hide it, but Jane could see right through her.

A smirk settled itself on his lips. "Oh my. You're a dirty girl, aren't you? I should've known my Lisbon liked to get nasty."

"You think you know everything about me," she chided, mimicking the same words she'd used just months ago when he hid her car keys in a puzzle box that was impossible to figure out. She'd ended up smashing the box with a hammer she kept in her desk drawer, something he hadn't saw coming.

"Well, I definitely like these new relevations," he said huskily, and just before he took her lips in another kiss, he slipped two fingers inside of her.

Her body arched, a moan ripping from her lips. His fingers were inside of her. Patrick Jane's fingers were inside of her. Oh god, she was going to cum by his fingers alone.

He thrusted them in and out slowly, taking pride in the way she whimpered and threw her head back in pleasure. The little noises she made sounded like music to his ears, and he was eager to hear more, so he added another finger to the mix.

"J-Jane," she whimpered, gasping when he curled his fingers inside of her, hitting a seemingly pleasurable spot that made her eyes roll back into her head. "Oh god."

"Look at that," he whispered, marvelling the clenching of her slick walls around his fingers. She was so soft, so tight. "A little Catholic school girl, being finger-fucked by her colleague. I wonder what people would think...fortunately, I don't care."

"Patrick," she bit down on her lower lip to suppress a scream threatening to escape her. His fingers felt so good inside of her, too good, and he kept thrusting them, harder, deeper, as deep as they would go. But she wanted more. She wanted all of him.

"Tell me what you want, love," he commanded gently, still moving his fingers inside of her.

"I want you," she admitted. "All of you. Please."

"If I fucked you now, that wouldn't be much of a punishment, now would it?" He quirked an eyebrow. "Good girls get fucked. Bad girls get pounded until they beg for mercy. They get their walls stretched out, they get fucked until they sob, begging to cum. But bad girls never get to cum. You get the same treatment, princess."

"Jane," she started to plead, but he merely shushed her and pushed his boxers down his legs, revealing his hard length that was already leaking with pre-cum. It was huge, so huge she didn't believe it was going to fit.

As if reading her mind, he chuckled and said, "don't worry, precious. I'll make it fit, I promise."

She didn't doubt him for a second.

"Now, let's lose these, shall we?" He slowly tugged her underwear down her shapely legs, tossing them somewhere in the room without care. She was fully naked in front of him now, and she wanted him so bad she could hardly breathe.

He nudged her legs apart with a hand, growling low in his throat as he took sight of the glistening treasure between them. She was so breathtaking, so perfect, and if he didn't get inside her right now he was sure he would explode.

His hands grabbed her hips and in seconds he was deep inside of her, thrusting fast and hard, showing just how eager he was. He couldn't help himself. His body ached for her, and he could tell hers did as well.

"Oh god," she whimpered as he pushed himself deeper into her, forcing himself as far as he'd go, stretching her until she was a moaning mess. "Patrick— Jane— oh my god."

Sweat beaded on his brow, yet he managed to cast her a boyish grin. "Don't summon god now, my dear. Let's keep this between us, yes?"

She couldn't even reply to that. She was too far gone. He felt amazing inside of her, hitting all the right places and filling her up completely, like he was the missing piece to her puzzle. Soon her lower body clenched after a particularly rough thrust, ready to cum, but Jane sensed her need and immediately pulled out of her.

Her eyebrows shot up at the sudden loss of contact. "What the hell are you doing?!"

He smirked devilishly. "I told you, princess— bad girls don't get to cum. It's your punishment for flirting with Haffner right in front of me."

"Jane!" She whined, "I wasn't flirting! God, I never took you for the jealous type."

His eyes glazed over with a deeper shade of lust. "I get jealous when I see my girl flirting with other men, even if it's just to receive information in a case. I get jealous when every man at CBI stare at your ass as you walk back to your office. I can't help it, Lisbon. Jealousy is human nature."

"Well, there's nothing to be jealous of," she promised, cupping his face in her small hands. "I'm yours and only yours, just like you're mine."

"Damn right," he growled before kissing her hard, devouring her lips with such hunger and intensity that came out of nowhere. But she wasn't complaining. She loved possessive Jane.

When he slipped inside her again, they moved together, slowly at first until his jealousy reappeared as he thought about another man touching her, hands that weren't his caressing her body, bringing her to ecstasy. He released a deep growl and gripped her tiny hips before pounding into her, relishing the way she cried out his name.

"It's me, Teresa," he said, his voice low and guttural. He held her eyes, green swallowed by blackness, with his own. "It's me who's fucking you, it's my name you're screaming. It's me who makes you cum so hard you see stars. It's all me. Not Haffner, not anyone else."

She couldn't speak with the way he was slamming into her, knocking the breath out of her lungs delightfully. She was holding onto his bare shoulders, nails digging into his skin hard enough to leave little crescent shaped marks. He didn't even flinch at the pain.

"You're mine," he breathed into her ear, pulling out and ramming into her again, slipping a hand between them to rub her throbbing clit. "Say it."

"I'm yours," she croaked, her eyes rolling to the back of her head as she felt her orgasm approach, threatening to take over. "Oh, fuck."

"Don't cum." He pressed hard on her clit, sending her into a frenzy of whines and whimpers.

"Jane...Jane, please."

"No cumming," he murmured, one of his hands now lifting to cup her breast. "Be a good girl and wait until I say you can."

As his thumb slid over her erect nipple, she bucked into him, feeling so ready her eyes began to brim with tears. "Jane, please. Let me cum. I need to— p-please."

"Just a little longer." He toyed with her swollen clit some more, and just before she sobbed he pressed a kiss to her cheek and nodded. "Okay, love. come for me."

With a relieved cry, she went over the edge, Jane soon following her. He embraced the shaking body that fell against him in exhaustion, murmuring, "good girl."

With his breathing heavy, he began running his fingers through her locks which were damp with sweat. They stayed there for a moment, basking in the sound of each other's breathing until he felt the strong urge to look at her face. He lifted her chin up with a finger, grinning at the dazed look in her eyes.

"Are you alright, my love?"

Swallowing, she managed a hoarse "never better."

He chuckled and planted a sweet kiss on her lips, planning for it to last only a second but getting lost in the taste of her instead. Just as his tongue started to explore her mouth her phone rang, jolting them out of their blissful moment.

Pulling away from him, Lisbon hopped off the desk and searched for her phone, still gloriously naked to his eyes. They roamed her hungrily as she found her phone and answered it professionally. "Lisbon."

He couldn't tell who she was talking to or what the other person was saying, but he got a clue when Lisbon glanced at him and smirked. "I'm sorry, Ray, but I don't think my boyfriend would like that very much."

Two seconds later she hung up, bending down to retrieve her clothes like nothing happened. But he felt the embers of jealousy sparking inside of him once again and he grabbed her by the waist, yanking her towards him until her body was flesh against his.

"What did he want?" He growled in her ear.

"He wanted to take me out for lunch," she responded nonchalantly, looking up at him through her long lashes. "But I figured you wouldn't want that. Would you?"

He shot her a glare, more towards Haffner than her. "Did you forget what happened before you answered the phone? Shall I have to make you remember?"

She pretended to think, leaning close so that her lips were only centimeters away from his. "Hm. It must've slipped my mind. I guess you should remind me."

Despite himself, he laughed, the sound lively and cheerful. He kissed her again, long and hard, planning to do just that.
