The one man I can't seem to get out of my head, I'm not allowed to have in it.

Felix. The alpha-male billionaire. He didn't pay any attention to me, but why would he? The prom king. The captain of the football team. A girl like me? I wasn't even on his radar...not until he knew he couldn't have me.

When our parents got married, everything changed. Felix and I moved in together. We became step siblings. My secret desire became my forbidden taboo. I hid it away, denied it existed, and tried to ignore my feelings and move on, but I couldn't.

I couldn't avoid him. Those eyes, those abs, that smile. No matter how wrong, I couldn't stop thinking about him. No matter how forbidden, I just couldn't say no. My skin ached at his touch, pleasure coursing through my body in pulses. My knees weak, just to be in the same room.

Then Felix told me how he felt, and my whole world crumbled around me.

No matter how much we wanted it, no matter how much our hearts and our bodies ached with desire, we couldn't, could we? Not as step siblings. Not like that. There were rules weren't there? Rules you just didn't break.
