“Lexie! Lexie!” Meredith hissed.

Lexie held a single finger up to her lips and continued to tiptoe towards the living room. Meredith fell into step behind her as the two of them edged along the wall. When they reached the doorway, the girls watched the scene before them in confusion.

“What are they doing?” Lexie asked, her voice full of confusion.

“It looks like they are watching the game,” Meredith commented, as if she was witnessing some extinct animal in its natural habitat.

“I don’t get it,” Lexie whispered. “Are they friends again?”

“Looks like,” Meredith said.

“How is that possible? They were at each other’s throats like less than six hours ago!”

Meredith shrugged. “Guess they’re over it.” She moved passed Lexie to walk into the living room.

“Where are you going?” Lexie asked, grabbing her sister’s arm.

“To sit with them,” Meredith said, surprised by Lexie’s reaction.

“Don’t do that!” She commanded.

“Why not?”

“You don’t want to scare them!” Lexie exclaimed. “They are in the male bonding zone. No vaginas allowed.”

“Really, Lexie,” Meredith said, sounding more and more like an older sister, “You are being ridiculous. If I want to go sit with my fiancé, I should be able to.”

Lexie started wringing her hands apprehensively, but she followed Meredith meekly into the room.

“Hi guys,” Meredith said with a smile. “What are you watching?”

“The Knicks,” Derek said, sipping his beer. Neither he nor Mark had looked up at the girls’ entrance into the room. They seemed absorbed by the game and oblivious to the two women standing in the doorway.

“That’s good,” Meredith said with a smile.

Derek grunted in response.

Meredith and Lexie exchanged glances, unsure of what to do next.

Mark then seemed to notice Lexie’s presence for the first time. “Little Grey, would you get us some pretzels from the kitchen?”

“They’re on the top self,” Derek added helpfully.

Lexie looked at Meredith who shrugged. She then left the room.

“Derek,” Meredith said.

When he didn’t look up, Meredith said louder, “Derek!”

“Hmmm?” Derek looked up at her, keeping one eye on the TV.

Meredith tried not to get too annoyed. “I am going to bed.”

“That’s nice,” Derek said, missing the subtle invitation in her voice.

Lexie flounced back into the room then and chucked the pretzels at Mark’s head. He caught them and gave her a smile. “Thanks, Lex.” He seemed to miss the look of annoyance that dominated her face.

Meredith and Lexie exchanged a glance and then both stomped from the room, not stopping until they were all the way upstairs and had collapsed on Meredith’s bed.

“This is bad,” Meredith said, once they were both on their backs and staring at the ceiling.

“So bad,” Lexie echoed. “Why did we not see this coming? This is such a mistake. We never should have encouraged them to make up.”

“When Mark was chasing after bimbos, he was always at the hotel and he and Derek would meet at Joe’s,” Meredith said, picking up where Lexie left off.

“But now,” Lexie said, “He is here with me all the time… which means that he will be with Derek all the time.”

“They will be permanent fixtures on the couch,” Meredith predicted gloomily.

“Never moving except to ask for more beer and pretzels,” Lexie added.

“Or to order pizza,” Meredith said.

“We will never see our boyfriends again,” Lexie whined.

“Not without seeing Mark or Derek too,” Meredith replied.

“The living room will be come a permanent sports center.”

“And they will consider showering a suggestion, rather than a requirement.”

“And they won’t talk to us anymore.”

“And there will be no sex!”

“This is bad,” Lexie said.

“So bad,” Meredith agreed.

“Boys are stupid,” Lexie growled.

“Yes, they are,” Her sister replied.

Lexie rolled onto her side and looked at her sister. “We can’t take this lying down.”

“We are lying down,” Meredith said, stating the obvious.

Lexie seemed unperturbed. “You know what I mean, Mere. We can’t allow them to stay like this for long. A couple more hours and Mark and Derek will be lost,” She said dramatically.

Meredith rolled her eyes. “What do you suggest?”

“We need to strike back,” Lexie said. “Hit them where it hurts.”

“Steal the beer?” Meredith suggested.

“No, but that is a good idea,” Lexie replied. She then offered, “Take the batteries from the remote?”

Meredith looked at Lexie with a new found respect in her eyes. “I like the way you mind works… but we need something bigger.”

Lexie’s face suddenly lit up in a smile. “Don’t worry, leave this to me.”

“Lexie…” Meredith trailed off. “What are you going to do?”

“You’ll see,” Lexie said, standing up. “You’ll have your boyfriend back in no time.” With that she left the room, and Meredith felt compelled to follow her.

Once Lexie was down the stairs, she strode confidently into the living room with Meredith trailing meekly behind her, a turnaround from their earlier foray into the room.

Lexie stopped at the edge of the couch, and looked down at Mark. “Enjoying the game?”

Mark looked up at her and smiled lazily. “Yes.”

“Good,” Lexie said. “I guess you will be down here for a while then.”

“Maybe,” Mark said, shrugging.

“That’s fine,” Lexie replied, a small smile playing about her lips. Her voice grew husky, “But as for me, well, I am going to go upstairs, strip off all my clothes, and get naked.”

Mark’s pupils dilated, and he swallowed in a reflexive movement.

“You still staying down here?” Lexie asked.

Mark shook his head dumbly, stood up quickly, and followed Lexie silently from the room with nothing more but a sheepish smile in Derek’s direction.

Derek stared after them with his mouth hanging open. Once they were gone, he shook his head, and turned off the TV. “I guess that is the end of the game.”

Meredith smiled. “It looked like your team was getting spanked anyway.”

Derek laughed. “True.”

Meredith walked across the room towards him.

“I think we made a big mistake,” Derek said thoughtfully.

“What’s that?” Meredith asked, settling next to him on the couch.

“We should have been trying to keep them apart… we should have tried to hook them up from the beginning!”

Meredith laughed. “Mark and Lexie, you mean?”

Derek nodded. “They are perfect for each other in a weird way. She obviously gets how to deal with him.”

“I can hardly believe that Lexie, my sister with the smiley face posters, brought him to his knees.”

“She really did, didn’t she?” He commented idly, lacing his fingers through Meredith’s.

“Derek?”

“Yeah?”

“My sister is kind of cool. You know, when she is not being neurotic and cleaning out the pantry. She is kind of cool, isn’t she?” Meredith asked, a rueful smile on her face.

He laughed. “Yeah, I think she is.”

Meredith smile, basking in the success of her sister’s diabolical plan. She would have to make sure Izzie didn’t dress her in anything too horrendous for the wedding, Meredith thought. She and Lexie had to watch each other’s backs.

They were family, after all.

* * *

Once Lexie had Mark safely upstairs and in her attic room, he turned to her with a lecherous grin and said, “I believe there was nudity promised.”

She laughed. “Really? I seem to remember it too.” With a wicked smiled upon her face, Lexie began to shrug out of her starred sweater. Her shirt was quick to follow, leaving her in her jeans and bra. “Why is it I always seem to be stripping naked in front of you while you are fully clothed?”

Mark, who was now lying on the bed, propped up on one of his elbows, smirked and said, “I am sure I have no idea, Little Grey.”

Lexie grinned back at him and shimmied out of her jeans, until she was standing before him in her underwear. “Here we are…” She said, her voice becoming low with desire. Lexie tried not to squeeze her legs together, it only made the desire she felt for him more acute. “Back at the beginning.”

Mark rose then, stalking over her. He yanked her head back, pressing passionate kisses to her lips. His tongue was seeking entrance to her mouth, yearning for an entrance that he would soon seek from her body as well. Mark eased her bra straps down her arms, gently dragging the pads of his fingers and thumbs along the smooth expanse of her skin. He then applied his fingers to the clasp of her bra, undoing the hooks that contained her. Once he freed her from the garment, Mark allowed his hands to roam to the front of her body and gently cup her breasts. Breaking the kiss, he lowered his mouth to the rosy tip of her right breast and took the nipple into his mouth.

Mark knew all the places to touch her; all the places to caress her skin which elicited moans from her mouth. They had been well learned in endless nights of drugged passion which left them both panting and yearning for more. He knew that if he pressed the indentations behind her knees that she would laugh and pull away, ticklish. He knew that if he sucked on the forefinger of her right hand that her eyes would grow dark and wetness would begin to pool between her thighs. He knew that if he dragged his teeth across her nipple that she would cry out…much the way she was doing right now.

Lexie was never an inactive participant though. As he preformed his gentle torture on her breasts, she kissed the flesh where is shoulder met his neck and then began to suck. When she felt the growing hardness against her stomach, Lexie smiled.

She knew things too.

She knew that if she laced her fingers through his hair, Mark’s eyes would roll back in his head. She knew that if she kissed her way down his body he liked it when she circled his belly button with her tongue. She knew that his sighs of pleasure sounded like growls, that he loved to kiss her as he thrust into her body, that his eyes would look almost black in that split second before he came, and she knew that in the aftermath he would hold her through the night because he couldn’t sleep without her.

And just like with her, he never had to tell her what he needed.

Lexie began to push the fabric of his black sweater up over the flat planes of his stomach. Mark soon lifted his arms and allowed her to draw it over his head, as if he was a little boy incapable of doing the task himself. Lexie had quickly learned that though Mark was fiercely independent in public, when they were alone, he liked needing her. The domestic qualities she had, which she had hidden from him in the beginning of their relationship, delighted him. Lexie had always wanted someone to share everything with and it had shocked her to hell to discover that Mark wanted the same thing.

Once his shirt was off, Mark took off his pants and pressed their bare chests together, allowing the fabric of her boy shorts to rub against his boxer briefs. Lexie teased her fingers along the dips and curves of muscles in his chest, letting her tongue follow. He smiled and cupped her face in his hands, forcing her to stop her torment and look at him.

“It was important to you that Derek and I make up,” Mark said, moving his hands down her back to gently cup her bottom. His voice was rough, but Lexie knew that when his voice was like that, he was at his most caring. “You were making yourself sick because of it…why?”

“I know you said it didn’t matter…but I knew you missed him,” Lexie said, her brown eyes wide and full of an emotion that he could not identify. “And I didn’t want you to…I didn’t want you to feel like you had given up anything to be with me.”

“Oh, Lexie,” Mark said hoarsely. “What the hell did I ever do to deserve you?”

Lexie giggled. “Usually when people say that, they don’t mean it in a good way.”

“I do,” Mark whispered. “I mean it in the best way possible.”

Lexie smiled, wiggling even closer to him. “Mark…”

“Yeah?”

“I really want you to fuck me now,” Lexie said, her eyes bright.

Mark felt himself grow even harder than he already was. “Yes ma’am.”

Lifting her in his arms, he carried her over to the queen bed in the corner and set her down on top of comforter. He quickly stripped off her underwear and his own, and fitted himself against her. Parting the soft skin of her thighs, Mark teased the slick skin between her legs until his fingers felt sufficient wetness. Then, without anymore delay, he settled himself on top of her and thrust forward into her tight heat.

Lexie tried to contain the gasp that always rose in the back of her throat when she felt Mark enter her. No matter how many times they did this, no matter how many times she felt him inside her…the newness, the rightness of it all…never faded.

She was sure that she would remember what this felt like until the day she died.

Lifting her knee and tucking it against his chest, Mark began to move. The sweet sensations caused them to squeeze their eyes tightly shut as they both began to build towards their mutual peak. Setting himself to the angle he knew she liked, Mark pressed forward with the express purpose of bringing Lexie to orgasm.

He didn’t know when it all had changed for him. He couldn’t pinpoint the exact moment, but he knew it had indeed changed. Somewhere along the way, it had ceased being about the sex and had become about something more. It was no longer just about him…he thought about her first.

Perhaps this was what love was supposed to be like.

The pitch of Lexie’s moans began to alter, and Mark knew that she was close. With his right hand, he reached between their bodies and rubbed her in a precise spot. She bucked off the bed and began to clench around him in a delicious way that hastened him towards his own orgasm. He groaned out her name and shuddered against her as she sighed his name into his ear.

“Mark!”

“Lexie,” was the only reply he could manage.

Afterward, when they were lying in each other’s arms, Mark savored the weight of her body where it touched his own. They were both slick with sweat and heat, but neither made an attempt to move away.

“I want to stay like this forever,” Lexie whispered.

Moving his hand off of his stomach, Mark entwined his fingers with Lexie’s and lifted their joined hands to his lips. He pressed a gentle kiss to her knuckles and watched as a soft smile lit her face. “Sleep, Little Grey.”

She closed her eyes and shifted closer to him. “Will you stay for breakfast in the morning?”

“Yes,” Mark breathed, closing his own eyes. “Any morning…as long as it’s with you.”

The End
