Ah, yes. Another story. This time it's Miley and Demi. Am I writing too much?
Btw, I wrote this on fanfiction.net first :)
----------------------------------------
Miley and Demi were sitting on Miley's bed in her bedroom. Her parents were out for dinner, and wouldn't be home before late at night. Braison was sleeping over at a friend's house, Brandi was at a party with some friends, Trace was on tour with his band, Metro Station, and Noah was sleeping in her room downstairs. They were more or less alone.
Miley was reading a book while Demi was trying to write a song. However, that was quite difficult because of her gorgeous best friend sitting so close to her, and she kept glancing at Miley's beautiful features. She stared at her silky chestnut brown hair, she just wanted to reach out her hand and slide her fingers through it. She kept her self from doing it though, because Miley would probably think that would be weird. Her eyes went to Miley's ocean blue orbs, currently too busy reading the pages in her book to be aware of Demi's admiring gaze.
And then there was her face. Her beautiful, flawless face with the softest skin in the world, and the most kissable lips in the universe. Demi couldn't count the times she had fantasized about kissing those lips, tasting her.
Her gaze wandered down her body. She was wearing a white see-through tank top with a black lacy bra underneath, and blue pyjama pants. She bit her lip.

'God, I want her so much,' Demi thought. 'Look at those perfect round breasts, I bet my hands would cup them perfectly. If I could just touch her like that once, I would definitely die a happy girl.'

She continued admiring her friend's sexy curves; her flat belly which she always have had a thing for, her tiny waist and her long, elegant legs.

'I wonder what she'd do if I just kissed her, right now. Maybe she'd like it. Maybe she'd let me touch her the way I so desperately want to touch her. Damn, it's so hard having all these feelings for someone who doesn't feel it back. To never get to show her exactly how much she means to me.'

She continued looking up and down Miley's body, not noticing that her friend had closed the book she was reading.
"Demi?"
She practically jumped out of bed at the mentioning of her name.
"Y-yeah?"

'My voice is trembling, great.'

Miley smiled softly to her friend. "Why are you staring at me?"

'Oh God, she noticed! What to do, what to do? Think of something!'

"Because I think you're beautiful."

'Nice save Lovato..'

She blushed. "You really think I'm beautiful?"
"Of course I do! Everyone with eyes do!"
"You don't mean that, you're just saying that because you're my best friend."

'I can't believe how low self-esteem this girl has. Has she not looked into a mirror lately?'

"How can you even think that's the reason I'm saying that?! Don't you dare think that you're not beautiful. Believe me, if I thought you were ugly or something crazy like that, we would most definitely not be on this topic right now!"
She giggled shyly. "I don't believe you though."
"Are you just fishing for compliments?" Demi asked, giving her a slick smile.
"No, that is not what I'm doing!" she protested. Demi just chuckled at her.
"That's OK, I'll play along with you."
"But I'm not.."
"Let's start with your amazingly hot body, shall we?"
She sighed.
"First of all, your legs.." She nodded towards them, slowly stroking her hand up and down the left one, causing Miley to inhale sharply.
"..is the legs of a super model. You look incredibly amazing wearing a short skirt or dress."

'Where does all this sudden confidence come from?'

"And your ass.." Demi grabbed her friend's hands and pulled her up so she was on her knees right in front of her, then slowly moved her left hand back to her ass and squeezed it lightly.
"... is oh, so sexy, especially in tight jeans."

'Oh my God, what am I doing? She's gonna stop me any minute now. Yell at me, hit me, smack the shit out of me or throw me on my ass out of the house. Something!'

Miley bit her lower lip. "Demi..."
"Shush, I'm not done yet." Her hands went under her tank-top and moved up to her stomach.
"I've always had a thing for your belly. It's so tanned, and you kinda have a girl sixpack."
"No I don't." Miley smiled weakly at her, shaking her head.
"Yes you do." She bent down, placing little butterfly kisses on her stomach before her hands trailed further up her tank-top 'till she finally cupped Miley's two breasts, making Miley suppress a moan. "We should stop this now..." It just came out as a mere whisper.

'I know I should stop, but this has gone too far. I just can't. God, they fit perfectly in my hands, just like I imagined they would.'

The chapter i wrote on fanfiction.net was too long to post as one chapter here, so I'm leaving you there. ;p
FYI, when I write like this: 'My voice is trembling, great.'
That's their thoughts in case you wondered. (less info)
