Luke knew it was wrong to have such thoughts about you. But he was pretty frustrated, with going to college and all. Very, very frustrated, actually, and you ― his sweet darling stepsister ― were just so pretty, and such a welcoming distraction from all the stress.

It's not like the two of you were really related. You lived together, sure, but that was about it. His mom and your dad apparently 'fell in love' or whatever (Luke didn't like to think about it, really).

And oh, he knew you wanted him just as much ― or, at the very least, he liked to think so. So what? Maybe the boy was a little delusional, but could you really blame him? Luke wasn't stupid, and he certainly couldn't have you spill his secrets... especially the secret you found out about by accident. One faithful evening, you found your underwear, messily shoved under his pillows.

So, what else is he to do but what he knows best. Manipulate...

"Gods, you're just filthy, aren't you," he laughs at your startled, flustered state when he suddenly appears in his doorway, blocking the way out. "I know about your sick little thoughts about me. No need to deny it." He'll have his way; have faith in that.
