Chapter Five The musty smell of stale air filled Meredith's nostrils as she entered the foyer of her mother's house. It had been years since she had ventured inside, even longer since she had called it home. Home; that was what it was about to become again. Her home. Letting her arms fall to her sides, Meredith stared at the empty living room, with its dust covered fireplace and dull wooden floors. Her fingers relaxed, the keys that had been grasped in her fist falling with a tinkling thump. The memory of waking up to a naked Derek floated before her. She hadn't known the effect he would have on her life, how much he would come to mean. She can't help but wonder, if she had known then what she knew now would she have still picked him up that night in the bar?"How could you?" She whispered to the ghost of the man she had loved. "How could you betray me like that?" It would have been less painful if he had cheated. Sex was purely physical. What he had done with Addison, making the conscience decision to father her baby, had been emotional. Emotion trumped physical every time. He couldn't have chosen a more perfect way to hurt her. Meredith closed her eyes, silently begging that the memories, that the pain, would disappear. Her lips started to tremble violently as the tears started to trickle down her ashen cheeks. Choking back a scream, she pulled her flat cell phone from her back pocket just as it started to ring. Through tear blurred eyes she made out the name on the caller I.D. Mark. "I'm at my mom's house," she sobbed, unable to keep it all in any longer. "Please, please. Please." She didn't even know what she was begging for, just that she had this need to see him, this desperate thought that he could make the world right again. Her phone slipped from her fingers, landing on top of her forgotten keys. Clutching her arms around her waist, she leaned forward, her hair falling around her face like a blonde curtain. She didn't notice she was falling until her knees hit the floor. A jarring pain rattled through her body, but she paid it no mind. Nothing compared to the ache in her heart. She didn't know how long she sat there, balled up and sobbing, only that one moment she was alone and the next Mark's strong arms were wrapped around her. "She's having a baby…" she sobbed, "she's having his baby." "Shh," Mark soothed, pressing her face into his shoulder. His fingers stroked her hair back, while he made comforting noises deep within his chest. She curled her fists into the soft fabric of his shirt, desperately clinging to him as though he was the physical embodiment of her sanity. "Calm down, Mer. Calm down and tell me what's going on." "Addison," Meredith spit out, bitterness dripping from her tongue like acid. "Addison is pregnant and the baby belongs to Derek." Each word felt wrong, like a slap to the face, and once she had said it aloud she let out another sob. Addison was giving Derek what she hadn't been willing to give. Mark's body tensed, his fingers tangling and pulling her hair. She barely noticed. Using her hold on his shirt for leverage, Meredith twisted her body until her face was even with his. She didn't stop to think about the repercussions, or that he was married to her best friend. There was no room for thinking, not anymore. She wanted to react, to feel. She needed those things; needed them desperately. There was nothing hesitant about her lips meeting his. This time she wouldn't let him pull back. Derek had broken the trust that had been between them, and she owed him nothing. She clung to that thought as she slid her tongue past Mark's lips, tracing the soft skin of the recess of his mouth. He seemed uncertain at first, holding back and letting her kiss him. His uncertainty slowly caved to the same sort of uncontrollable need that coursed through Meredith. He took control, grasping her slender hips and yanking her lower body out from under her. She fell back against the dusty floor, not carrying that the wood was cold and hard. With wide eyes, Meredith stared up at Mark's face, his expression difficult to make out in the dark. She wondered what he was thinking. Was he thinking about the fact that he was unbuttoning the pants of his wife's best friend? Or was he thinking about the fact that the woman beneath him was lifting her hips, inviting him to remove her yellow lace panties? Perhaps he was thinking about both. It didn't really matter. They beyond the point of anything really mattering. Biting her lip, Meredith closed her eyes. It had been so long since she had felt anyone but Derek touch her, and the feel of Mark's finger tips tracing her lower abdomen was like feeling a man touch her for the first time. Senses she had long forgotten were reawakened and craving more of the magic that trailed after Mark's fingers. She needed to feel more, to see more. She reached for the hem of his shirt and tugged it up, over his head, and tossed it to the side. Her greedy eyes took in the golden expanse of muscle that was now on display, just for her. In slight awe, she grazes the tips of her fingers across the warm flesh, needing to be sure he was real. Slowly, she lets her fingers inch toward the snap of his jeans, once there she paused. If they did this, there would be no going back. Derek and she might be able to recover the Addison debacle, but this, this would destroy her marriage. Without a second thought, Meredith undid his jeans, her hand slipping inside to cradle his long, hard cock. She could see why Cristina had stayed in a loveless marriage for so long. Mark's large cock alone would be worth it. She shook of thoughts of Cristina, as she didn't want to face the fact that she was shoving faded blue jeans down the hips of her best friend's husband. There would be plenty of time to dwell on that later. "Meredith," Mark murmured, his face looming over her's. He was having second thoughts, she could feel him retreating. Under normal circumstances she would understand, these were not normal circumstances and she needed what only he could give. She needed to feel close to another human being, even if it was a mistake. "Please," Meredith whispered, her green eyes pleading. Didn't he understand? She had gone so long with out feeling another human being touch her, hold her, that she had forgotten how detrimental it was. It wasn't a feeling she enjoyed. He visibly swallowed a lump in his throat and then positioned himself between her thighs. "No turning back," he murmured. She echoed his sentiments in a throaty voice. She kept her eyes on his as he started to enter her, stretching her, filling her. The wonderment she was feeling seemed to be mirrored in his gaze and only grew as he withdrew and then thrust again. Over and over, slow at first and then turning desperate, he thrust. It wasn't making love, but nor was it fucking. Meredith couldn't put a name on it. It just…was. And, no matter how wrong it was, it felt so very, very right. Our hearts beating fast And my body cries I want it to last It's burning inside Britney Spears-And Then We Kissed
