Passionate

Casey McDonald is a cheating good-for-nothing tramp. Or at least that's what she tells herself when her mouth waters at the sight of Derek after he is done working out. Sweat on Derek is strangely appealing and she wants nothing more than to kiss all the strained muscles and bruises until they stopped hurting.

That had done her in. George had called her away from a date with Truman asking if she could pick Derek up at the gym. She had agreed but of anger. Truman had just added the waitress' phone number in his phone, right in front of her. Casey got to the gym feeling disgruntled with life and more livid when she realized she had to go inside for Derek.

His shirt had been off, wrapped around his head to keep the sweat off and he had stared at her with surprise. The attraction had been so much and she had kissed him in a frenzy, roughly pulling his hair through his shirt. Even now, months later, she can still taste the tang of his sweat.

Kissing Derek was like feeding desperation. She always felt the need to kiss him harder and with more passion. Once or twice, Casey has even pushed him against the stairs at a movie in her overwhelming desire.

She is usually a very good girl. Everyone knows this. Which is why Casey thinks they'd be surprised to know her stepbrother slips into her room at night just to give them both a release. A release she is coming to crave less and less. Casey will not delude herself into thinking it's because she has seen the 'error of her ways' but rather because it is his body she craves most – not the release.

Like the other night, she had unexpectedly found herself touching him as much as she could. Just the feel of him was sometimes enough. The other times when it wasn't enough, she'd give him a look and he'd smirk. Within moments they'd be in his room undressing. His room because no one noticed when his door was shut.

Sex and Derek was like feeding a fire. It never feels enough to her and she longs to keep him in her, even when she's aching and tired. She pleads with him on more than one occasion. More than once, Casey has purposely seduced him to feel his body against her.

Casey loves college. She doesn't have to hide her raw desire for Derek anymore. Her boyfriend was going to, well, somewhere not with her and Emily was at Toronto while her family stayed in London. More than once, she has stayed the night in his dorm room and made out with him at the front of the school. It's liberating and she can tell Derek loves it too from the way he gets more adventurous.

He once went down on her by the reference stacks in the library. The feeling, the gentleness made tears comes to her eyes while she kissed his neck in gratitude afterwards. He loved her. He had said so with his actions and the way he smoothed her dress down.

Being loved by Derek was like eating ice cream on a hot, sweaty day. It was refreshing and just so new. Casey now has a newer appreciation for him. She takes care of him by spoiling him, but also by forcing him to study. She can remember fondly the time she had put Moby Dick trivia on her clothing and when he got it right, the clothing came off. He had aced the test, of course.

Emily calls crying, demanding answers. She tells Casey that she thinks Derek is cheating on her. Casey is surprised when no feeling of guilt springs up. Instead, she calms asks how Emily knows. Emily tells her that Derek never wanted her to visit nor does he ever want to visit.

That strangely enough makes her happy.

And her happiness she was rapidly finding made him happy too.
