A/N: Hi everybody! Thank you so much for all of your wonderful comments! I know I've said this before, but they really help me keep writing. Sorry I've been gone for a while; this chapter gave me lots of trouble. I wrote out about three drafts and couldn't decide which one was the best. I think it's this one. (I hope you think so too!) I also want to put out a warning: Most of this chapter is very M rated. You have been warned. Oh, one more thing. The flashbacks from the previous week are in italics. I hope it's not too confusing. As always, please review!

Rrrring. Rrrring. Rrrring.

Derek flipped open his phone. "Meredith? Is that you?" he asked hurriedly. He hadn't seen her or heard from her in a week.

"Derek, I - I'm sorry. I just…we…can't do this. Not tonight, please." Meredith pleaded as a single tear ran down her cheek.

"Why are you crying? I didn't say something, did I?"

"No! I mean, of course not. You're perfect."

"Then why are you crying?"

"Because once we…then you'll leave."

"What? What makes you think that?"

"They all do. That's all I'm good for. You've had your little fling, and then you're done."

"Uh, yeah. Yeah, I'm here," Meredith responded softly.

"God, Mer. I was worried. Search and rescue party worried. Are you okay?"

"Yeah, I'm fine."

"Is that why you think I'm here?"

"Um, no. You're too perfect."

"Why do you think I'm here?"

"I don't know, Derek. I just know that this feels wrong right now. I'm not, you know, ready for someone like you."

"You're a breath of fresh air. You're different from everyone I've ever met."

"So are you. And right now, that scares the crap out of me. Can we just…not do this tonight?"

"Of course, Mer. Whatever you want."

"About last week -" Derek started.

"No, let me talk. I know you're not, you know, that guy. You're prince charming on a white freaking stallion. I was just scared, okay? But I'm better now. Really, I am. So, can I come over when you're done work?"

"Are you sure you want to?"

"I'm sure." Meredith smiled. She knew Derek couldn't see, but she couldn't help it. No guy had ever asked her that before. It felt good.

Meredith knocked on the door of Derek's apartment. He had spent half an hour on the phone with her, trying to give her directions. She sincerely hoped she'd gotten to the right place. She was elated to see Derek open the door.

"Hi," he said awkwardly.

"Uh, hi. Can I come in?"

"Sure." Derek held the door open for Meredith as she walked in.

"Are you ready? I spent all week thinking this one up."

Derek nodded eagerly.

"I dare you to make me scream your name without touching me."

"The first part I've wanted to do forever. The second – not at all? Really?"

"I gave you a dare. Accept it first, and then I'll decide. You don't have to accept, though. You could back out, if it's too hard for you. We both know that I would've won anyway."

"It's not too hard," Derek said, a smile tugging at the corners of his mouth. "But I can't touch you? At all?"

"Fine," Meredith sighed. "You can touch me. But you can't use your hands, arms, legs, feet, toes, or fingers."

"What about -"

"No," Meredith laughed. "You can't use that either."

"That? You refer to my penis as that?"

Meredith giggled. "Would you rather it had a pet name? Derek Jr.? Little Derek? Itty-bitty Derek? Tiny?"

"What's with all the littles? And itty-bitties? Tiny?!"

Meredith collapsed in a fit of laughter. "T – T – Tiny!" she laughed.

"That's not what they usually call me," Derek said smugly.

"I'll be the judge of that." Meredith was still giggling.

"Well, since I can't use that, you have to find out later. Right now I need you to lie down."

Meredith nodded. She had been thinking about this dare the whole week. If Derek were actually able to do this, she'd be amazed. Derek smirked as he watched Meredith lie down on his bed, her silky hair creating a halo around her head. He bent down slowly so his mouth was right next to Meredith's ear. He lightly nipped her earlobe, sending shivers down her spine.

"No teeth!" she protested.

"That wasn't part of the deal."

"Well, now it is."

"Too bad."

Derek's hot breath on her neck gave Meredith goosebumps. She squirmed as he moved towards her collarbone, letting his stubble tease her skin. Finally, he arrived at the first button on her shirt. Skillfully, he took the button in his mouth and undid it using only his teeth.

"I'm impressed," Meredith whispered.

"You should be."

"Whatever."

"It won't be 'whatever' from you much longer," Derek said in a husky whisper. When he had undone all of the buttons, he pulled Meredith's shirt off entirely. Underneath, she was wearing a tiny lilac bra with a little rose sewed to the center. He traced the outline of her bra with his tongue, following an imaginary line over her breasts and between them.

"Hey, no tongue!" Meredith squeaked.

"You didn't say that either."

"Well, whatever. But no tongue below the waist – that would be cheating."

"Fine," Derek sighed. He leaned in and flicked his tongue under Meredith's bra, making her squirm. He smiled to himself as he saw her frustration build with every lick, every nibble, and every breath.

"Ahh…fine! If you won't take it off, I will!" Meredith reached to her back and unhooked, her bra, letting her breasts spill out. "Somebody had to," she murmured.

"Derek? Is that you?" someone yelled from the front of the apartment.

"Shit! Mark," Derek muttered.

"Who?" Meredith asked.

"My roommate. But he's practically my brother; we've been best friends as long as I can remember."

"Derek?" Mark yelled again.

"What is it, Mark?" Derek yelled back.

"Am I interrupting something?" Mark asked slyly. "Is that girl here? The one you always talk about…Marybeth!"

"It's Meredith!" Derek and Meredith yelled in unison.

Mark laughed when he heard two voices coming from Derek's bedroom. "Sorry to interrupt, kids. Don't mind me; just keep doing what," he chuckled, "or who you're doing."

"Derek!" Meredith yelled, a little too loudly.

"What?"

"Why didn't you tell me you had a roommate?" she hissed. "We could have gone to my place."

"He wasn't supposed to be back for another hour. Oh, by the way, you just screamed my name. And I didn't touch you," Derek whispered smugly.

"You ass!" Meredith yelled.

"At least I'm a sexy ass."

"Arrogant."

"Sexy."

"Arrogant."

"Sexy."

"Fine," Meredith sighed. "How about arrogant and sexy?"

"I think I can deal with that. By the way, it's my turn now."

"Whatever. But you owe me, you cheater."

"I can make it up to you," Derek said mischievously. "But it'll be hard to wait until tomorrow; you already have your shirt off. Maybe I could just…"

"Nope. You cheated, you pay the price. I'll meet you at my apartment in an hour."

x.x.x.x.x

Ding, dong.

Meredith slowly opened her apartment door. "You're early," she said.

"I couldn't wait. You're so irresistible."

"Come in," Meredith giggled. "Are you ready for your dare?"

"But it's my turn," Derek whined. He crossed his arms and pretended to pout.

"You'll get your turn."

"Fine," Derek sighed.

A wicked smile flashed across Meredith's face. "I dare you to watch me touch myself. You're not allowed to speak, touch, or intervene in any way. And you're not allowed to touch yourself either," Meredith said as she led Derek by the hand into her bedroom. Derek's body tensed at the thought of watching Meredith touch herself for him.

"Where should I sit?" he managed to ask.

"Anywhere you like," Meredith said coyly.

Derek sat on the chair that faced Meredith's king-sized bed. He watched her undress herself, wishing he could be the one taking her shirt off or pulling down her skirt.

"Oh, I forgot. You're allowed to do two things. You can take off my bra and my panties," Meredith giggled. She knew this was going to be the hardest dare for Derek yet.

Derek gulped as he stood up and walked over to Meredith. He savored the feeling of her creamy skin against his hands as he smoothly unhooked her bra. As he reached around to remove it, he cupped her breasts in his hands.

"What did I say about no touching?" Meredith asked as she playfully batted his hands away. Derek groaned as he moved to remove her lacy panties. He slipped his fingers under the bands and gently pulled them down her hips and legs. He ached to grab Meredith and ravish every inch her, but he resisted. He had to hold out to the end of the contest, no matter what.

Meredith slowly lay down on her bed ran her hands across her body, caressing and squeezing her breasts. She softly licked her fingers and moaned as she traced them in circles around her rosy nipples. She smiled to herself when she saw the look of utter frustration growing on Derek's face. Gradually, Meredith's hands worked their way down between the valley of her breasts. Shivers shot down her spine as she brushed her hands against her inner thighs, imagining Derek's hands where hers where. Licking the tip of her finger again, she gasped as she began to stroke herself. She steadily increased the pace of her fingers, slipping one inside. She slipped another in and slowly pumped them in and out, her breathing becoming deeper and more erratic. "Ahhh….ahhh," Meredith panted as she closed her eyes. "D – Derek!" she exclaimed as a powerful orgasm shook her body. She could feel herself clenching and unclenching around her fingers; she wished it was Derek that she was clenching around, not her own fingers.

Derek almost went over the edge when he heard Meredith scream his name. "You screamed my name," he murmured, "and I never touched you." A smug smile of satisfaction spread across his face.

"You ass," Meredith panted. She was still recovering from her display moments earlier.

"Is the dare over yet?"

"I think so."

"Are you sure you're okay with this?"

"I'm sure," Meredith said quietly.

"Thank God," Derek groaned. "I'm going to make you scream my name for real. But only if you're sure."

"I'm sure," she repeated.

Meredith reached up to kiss Derek, lightly running her fingers through his hair. "I'm really sure."
