Mess With My Stepbrother

"I'm gonna burn in hell for all the filthy things I'm thinking about doing to my innocent little stepsister, but I can't help it. Haven't been able to for the last couple of years and constantly pushing her away is wearing on my last nerve. Claiming her might tear our family apart, but she's always been my Bookworm, ever since my dad started dating her mom and they finally decided to get married. I've always been protective of Lily. Years ago, she was a cute kid who needed a big brother to look out for her. Now, she's not so little, but just as adorable, and I still want to look out for her. Want to do a whole lot more than that. I came home from college the Thanksgiving right after she turned eighteen and spent the whole week hiding an inconvenient boner. I should be ashamed of my feelings, but it's not like we're really related. God, I wish I didn't feel this way. But it's too late now. Those long, long legs haunt my dreams. I want to feel them wrapped around my waist while she reads to me from one of those filthy books she reads on the sly. My little Bookworm has her secrets, just like I have mine."
