When I Kissed the Teacher

Seattle Grace Hospital, Seattle, WA 2008 - S5E10

"Teach me," she's standing in front of him saying. He's explaining all the ways in which this is a terrible idea. He promised he wouldn't. And yet here she is and it's kind of not his fault. She showed up on his doorstep and walked right in. What else was he supposed to do but surrender? Really if Derek asked he could blame her. But he wouldn't. It was his fault for leading her on. "Come on, am I really so bad?" How on earth could she think she's bad, she's perfect. She's looking at him with fierce desperation. If he told her he didn't want her, it would break her heart.

He paused for a long time before saying, "no." It was blunt and to the point, it wasn't breaking his promise but it wasn't breaking her either. He had to decide, but in so many other ways he already knew what he was about to do. Perhaps he needed those few seconds to apologise to the universe for breaking his promise. A few seconds of calm before the storm. "I am."

It all came crashing down around him, high waves of adrenaline pumping through him in those tiny, determined steps between them. She still looked scared of rejection as he took her cheek in his palm and tilting her chin up. He put his mouth on her. He threaded his lips through hers and he felt her hand cupping the back of his head.

Why was he so good at this? Lexie thought, her tongue tangled in his. Because he's Mark Sloan, that's why, he has a reputation for a reason. He wrapped her in his embrace, getting in a good couple rounds of kissing before he pulled off his shirt. What a reason! She felt her way over his body, trying not to fumble in awe. She could easily stop and panic if she took a minute to appreciate just how hot he really was. But she didn't, she couldn't even open her eyes because he was touching her. She'd already taken off most of her clothes so his fingers were slowly rising over her stomach. Skin on skin was already too intense. Little sparks rose through her, with each small touch, she felt more and more turned on.

She'd been imagining this for weeks now. How he would feel on her, against her, inside her. How his hands would graze over her back, how his lips would move down to her neck and seemingly devour the skin he found there. She hesitated for a moment to let his gentle lappings take effect. He pulled softly enough not to leave a mark, he didn't want the interns gossiping the morning. He didn't want her to get judged for this, he couldn't let this ruin her reputation.

He had to get out of those pants, and fast. Her fingers started grappling with her zipper, he chuckled against her when he realised what she was trying to do. Leaning back from her, he undid her jeans quickly and dropped his sweatpants to his ankles. He pushed her towards the bed, they had to break contact for a few painful seconds so she could make her way to the headboard. He crawled over her small form and put his lips on hers again. She wriggled out of her jeans then scooted under the covers, she wanted this to be normal, to be somewhat like she'd imagined. But she was also letting him take the lead.

He slipped her out of her underwear. Throwing it somewhere across the room. He kissed over her chest and her stomach, down past her naval until he reached the gap between her thighs. His tongue nipped at her more delicate skin until she was moaning. With her head back against the pillows, her eyes tight shut and her hand on her forehead, she looked like she'd totally let go. He'd never seen her that unhinged before. Always so professional, always the top student. Now she was unravelling in his bed as he got to pleasure her.

He paused his ministrations to look at her for a moment. "Mark, please..." She begged, biting her lip slowly and threading her fingers through his hair. She tugged lightly and urged him on.

"What do you want?" He asked seductively, his tongue flicking over his lower lip in suggestion as he began to play with her. She groaned and stared down at him. She sat up on her elbows and gave him a full-on passive aggressive glare before he gave in and dove into her. Her head rolled back almost instantly as she let out a strained moan. It was the perfect sound. The noise of pure rapture, she was enthralled by the magic of his tongue.

He let his fingers trail over her legs, lightly stroking her while he massaged her clit in circles. Shortly after came the pleas of his name, over and over again like a prayer. He stopped just before she was about to explode. He pulled himself away and let his mouth explain her taste to her. She fiddled with his underwear until it was off. She stroked him until he couldn't help but break their kiss. "Lexie-" he mumbled against her, it could've been a warning but she took it as a sign to pull him closer to her.

"I want you." She replied, then she leaned up and whispered in his ear. "I want you to take me."

So he did. In and out of her like a well-oiled steam train. She moaned into his neck and as she took all of him inside her. Her breath was hot and tickled his skin, her kisses peppering him as she struggled to keep up with him. She flipped them over so she could sit on his hips, his length still inside her she bent over and reattached her lips to his. Sharing tongues and moan for moan after each straining breath they worked up to joint climax.

He brushed her with his lips and then reached behind her and unhooked her bra. Lexie tried to hold in her gasp, but it was bubbling up in her throat and she had to let it out. Mark let each strap fall down her arms until the garment dropped away from her all together. Then he ravaged her breasts. His tongue wrapped around each nipple in turn, the lands few coils of her energy collapsing as his spare hand came down to rub over her clit.

Her small bundle of nerves vibrated happily as she came around him. She shuddered slightly under his expert hand, letting him turn her back onto the bed as he finished himself. The last few strokes were almost exhausting but when climax came it was heavy and electric. The static energy of his orgasm rocked him back to the room and he gazed at her. Lexie was panting with her eyes closed but her face was flushed. He'd done that. He'd put her into a total state of ecstasy. How could he go back now that he had seen this? He had partially promised himself that if this happened it would only be the once and that Derek would never know. But how could he keep that? Not when she was lying underneath him in utter perfection, in her own spinning world.

Her eyes fluttered open for only a few moments to look up at him and laugh. A tiny release of laughter that warmed him. He leaned down and kissed her delicately, almost merging his face into hers. He melted them into the bed and continued to kiss her. It was like a teenage make out, even if this was all they did now, that would be fine because her lips on his was enough. Or at least his post-sex brain thought it was. He would find the next day when she walked in front of him down the hallway he had to resist all urges to pin her against the wall.

When she fell asleep in his bed, he kissed her forehead and watched her sleep for an hour before finally putting his head down. He would tell no one about this, and he definitely had no intention of doing this again. Well he had the intention but his willpower was refusing to give in. He could have her now and then he would have to give her up because she was Derek's little sister now too.
