Chapter Four

A Fine Line between Love and Hate

Izzie hummed to herself as she opened the fridge, scanning the contents critically. God, but Meredith needed to buy some food….there was nothing but leftover pizza and Chinese takeout…and tequila and beer… She bent over, rummaging for the last eggs that were sitting in their case on the bottom shelf.

"Nice view…" Mark whistled, and she turned around to look at him, where he was leaning against the kitchen doorway, arms crossed, dress slacks slung low on his hips. All of that muscular chest was on display, and her fingers itched to trace that taut definition all over again. She couldn't seem to get enough of touching him.

"Not bad yourself…" she murmured, setting the egg carton on the counter. Her body tingled with anticipation as he stalked across the floor to her. He caught her around the waist, picking her up easily. She made a little squeak of surprise, before he set her onto the island. The kitchen was dimly lit from the light over the stove, and it seemed cozy and warm.

Placing his hands on either side of her, Mark leaned down to kiss her, slowly tracing her bottom lip with his tongue, which set off more little shivers down her spine. When he finally drew back, she was breathless again, having lost track of what she had been doing before he joined her. Nothing else seemed to matter but having those hands on her again, and fitting herself around that erection that was demanding attention again. Damn, but the man had amazing recovery time.

"Didn't you say something about food?" he asked her, running his fingers along the inside of her thighs, coming to rest at her hips.

"Huh?"

"If you're going to seduce me again, woman, I might need something to keep my strength up."

Izzie blinked, "Oh, right, food---"

Mark chuckled softly, tipping her chin up. "You okay, Izzie?"

"I think so…" Izzie leaned back, letting his shirt fall away from her. "There is something else you can have right now…" she murmured suggestively.

"Insatiable little minx, aren't you?" Mark asked, his eyes hot as he contemplated her nearly naked body displayed for him.

"You seem to make me lose all my inhibitions…."

"Well, then, let's see what else I can make you do then…" Mark backed away from her for a moment. "Don't move…I have plans for you…"

Izzie stared at his broad back as he searched through the fridge. "Not much in there, babe…" she calls out, her body humming in anticipation.

"No…but there is this…" He held up a couple of cups of chocolate pudding that she'd overlooked earlier. "I can improvise…" Giving her a wicked look, he scooped out some of the pudding, and smeared it over her breasts, taking time to decorate her nipples with small dabs. From there, he trailed down across her belly, making her gasp from the shock of the chill. He leaned over and began to lick it away from her, over her hard nipples, his tongue stroking and licking, the sweet chocolate melding with the taste of her. He left wet trails along her body, making her moan and giggle alternately.

"Hungry, Mark?" she teased him, arching her back, thrusting her breasts towards him.

"Hmmm…" he paused, considering. "I could eat something…" he said suggestively, rubbing the heel of his hand over her damp pussy. "Something wet and hot…"

"So what's stopping you?" Izzie taunted him.

"Just admiring the view," he murmured, before dipping his head and stroking his tongue over her damp folds, tasting her juice mixed with the chocolate, more wet and creamy than ever. Deeper and deeper, his tongue ravaged her, sucking on her clit, feeling the spasm of her core as she started to climax. Coming hard, bucking and moaning as he kept up the torment, until she was limp with pleasure.

"Oh my god…" Izzie sighed, wondering why he was able to make her lose all of her inhibitions so easily. She was fighting to keep her control, but he was doing things to her she never anticipated.

"Two can play this little game, Mark…" she murmured, moving away from him and grabbing one of the pudding cups.

"What d'you have in mind, babe?"

Izzie just grinned at him, unzipping his pants in a swift motion. "You think you're the only one who can do this?" She smiled sweetly at him, as she spread some of the creamy cold pudding over his cock. Mark flinched at the sensation, but stood still, while she dropped to her knees in front of him. Her warm tongue contrasted with the cold, and his head went back at the feel of it. She swirled around the sensitive head, and back down along the aching length. His hips flexed in response, driving against her, need more and more. Heat and pressure built up, and he groaned and swore, grabbing the edge of the counter to stay upright.

"Take it all, babe…you do that so good…" he muttered, before the climax started to take over, his blood pounding through his veins, as he lost himself against her lips. His legs shook from the effort of standing, and he sucked his breath in hard, trying to regain some control.

Izzie let him go, slumping to the floor, half laughing, half gasping. Mark looked down at her, a smile on his lips. "You look good," he said, grabbing the bottle of tequila from the counter. He sank down beside her, offering her a drink. He couldn't believe just how much she was willing to go along with him. Her smile was warm, as he surveyed her appearance. Hair in a tangle, smears of chocolate over her skin, her lips swollen from his hard kisses.

"Now, this is what I call having fun in the kitchen," she giggled, taking the bottle from him. "I'm not going to be able to look at this counter quite the same way again…"

"Just think of me…" he smirked, running a hand over his hair. "Hey, did you like the roses?"

"Oh yes…sorry…" she giggled, the tequila starting to hit her. "They were lovely!"

'Too much tequila for you," he said, taking the bottle away from her. "And we still need some real food." He rested his head against the cupboard. Somehow in his experience with women, this was the first time he had been naked in the kitchen, sharing a bottle of tequila, with chocolate pudding the only sustenance available. Then he grinned, unable to keep from laughing at the situation.

"What?"

"This is just amazing…you are an incredible woman, Izzie Stevens…" he finally said, controlling the laughter.

"Yeah, that's me…" she agreed, with a little hiccup. "Don't you forget that either…"

"Oh I don't intend to," he assured her. "Definitely not…"

^-^-^

Two weeks later….

"So you're still having sex with that lawyer?" Cristina asked Izzie as they sat at the bar in Joe's. "You really need to give me details, Iz…"

"What kind of details?"

"Well…he's got such a reputation around Seattle…he must be pretty well endowed…" Cristina smirked over the rim of her glass.

"Cristina!" Izzie protested, but then she giggled. "I won't say I'm complaining, that's for sure…"

Cristina raised one expressive eyebrow. "Really? That must be why he has so many women falling over him…"

"Are you trying to piss me off? Cuz I really don't care…we aren't exclusive, he can date anyone he wants to." Izzie tossed her hair over her shoulder, trying to portray her utter disinterest in any of Mark's women. "I know what he's like."

"Oh good, because I saw him on TV the other night, escorting some rich socialite to that big charity dinner. I'm surprised you didn't see that."

"She's probably a client."

"Probably, sure…"

"I don't care, anyway. Just because he's good in bed, and can make me scream in more ways than any other guy doesn't mean I care about him…" But Izzie felt a little twinge of jealousy at the thought of Mark doing all those decadent sexy things to someone else.

"Good…then you won't yell at him when he sits down beside you," Cristina smirked, looking over her shoulder.

"What? He's here?"

"Looking for me?" Mark asked easily, sliding onto the stool beside Izzie.

"No…not at all…" Izzie was determined not to act needy, not to give him the pleasure of knowing she cared if he was there or not. Sex without strings was getting to be tricky, she acknowledged. "If you're here, then drink. That's what people do in bars – they drink!" She raised her glass towards Joe for a refill. "More tequila!"

Joe brought the bottle over and poured another shot for her. He glanced at Mark, who shrugged resignedly. "Just bring me a Scotch, a double…" He sipped it slowly, wondering what happened to make her upset. The alcohol soon burnt away any reluctance on his part to pressure her, and he touched her arm. "Izzie…just what the hell is wrong?"

"No talking...." she murmured, still not looking at him, "you're ruining my perfect drunk."

Mark frowned and made eye contact with Cristina behind Izzie's back. She just shrugged, unable to provide any help. He returned his gaze to his glass and downed a few more drinks, as Izzie continued with the tequila. Nobody spoke.

Finally, unable to stand it any longer, Mark rose to his feet a little unsteadily, and grabbed her shoulder so she had to turn to look at him. "Iz, whatever has you pissed at me I would like to know. I thought we had something between us." He took her face and kissed her lips hard, forcing her mouth open. The sudden attack took her by surprise and she responded involuntarily at first, then with increasing passion. She rose off the barstool to put her arms around his neck and pull him closer. Mark pushed her back against the bar, bending her backwards while grinding his hips into her.

Coming up for air, she glanced down at his crotch, while the other bar patrons clapped and whistled. "Satisfied?" she smirked, tequila and lust fogging her thoughts equally at that point.

"Not now," Mark retorted angrily, not caring how it sounded.

Izzie gasped, and raised her arm to slap his face, but he caught her hand, and they stared at each other, chests heaving and breathing hot and ragged.

Cristina jumped up and tried to break them apart. "Maybe you two should just go home, separately. I can drive you."

"NO!" both Mark and Izzie said simultaneously.

"We're going," Mark finally said, pulling Izzie with him, tossing some cash on the bar for the drinks. They stumbled outside, Izzie half giggling, half indignant. He found his keys and opened the car door. "You make me crazy, Izzie," he told her, pushing her backwards against it.

"You think you're so hot!" she retorted, eyes flashing.

"You seemed to think so!" he countered, holding her hands tightly.

"You're just a manwhore!"

"You didn't complain before!"

"You have morning breath!"

"You hog all sheets!"

"Fuck me!"

Mark stared at her, surprised by the unexpected end to the arugument. With a low growl, he pushed her further back and into the backseat, and fell onto her. Izzie pulled her shirt over her head, and put her hands on her breasts, offering them up to him. "Is this what you want?" she taunted, her bottom lip in her teeth. She pinched her nipples and watched his reaction. "Fuck me, Mark," she implored. She raised her hips and pulled the zipper of her jeans down, wiggling them off her hips, taking the panties with them. Her hand went to her pussy, parting the swollen lips and thrusting her fingers in, as her other hand massaged her breasts.

"You want me, Mark, you want all of this," she moaned, playing with herself, rolling her hips and closing her eyes. Mark watched, mesmerized as she brought herself to a small climax, so dazed that he forgot to join her. Watching her fingers slide in and out, wetter and wetter each time they came out of her. "Are you just going to watch me, or get down here and fuck me?" she demanded.

Mark threw off his clothes in one swift motion, falling onto her in a fever. He put his mouth on her breast, and bit her nipple hard. "You can be SUCH a bitch," he growled against her skin. "I don't know why I put up with you." He kissed her belly, and flicked his tongue across the wet lips of her pussy.

"Because you like me," she purred, arching up to meet him. "And I fuck you like nobody else!" she hiccupped.

Mark parted her knees, and slid in between her legs. "You think so?" he asked. "So have your fun with me now…isn't that all we are...just in this for the sex?" And he pushed up and into her, enveloped in her tight pussy, his eyes hot on her in the darkness.

"Fine!" she said, squeezing around him.

"Fine!" he muttered, thrusting into her, then holding himself up over her. His arms shook and he lowered down slowly, capturing her mouth. Izzie whimpered and met his thrusts, spreading wider and wider for him. Sweat covered them both, and the windows of the car slowly fogged over. She pulled him closer, raking her nails down his back, scratching his ass.

Little cries and whimpers escaped her as they pounded together, his cock large and filling her completely. "Mark, god, don't stop…" she cried out, as her orgasm started to peak, taking her away. He lost himself in her, swallowed up in her tight pussy. Screaming and gasping, they fell together. He pushed the hair out of her eyes. "I hate you," she said finally, "why do you keep being so perfect?"

"I don't know, it's a gift," he replied. "I hate you too," whispering, kissing her softly.
