My sexy-ass stepbrother is going to be the death of me.
When my mom decided to marry his hillbilly dad, I was pissed.
I mean, their woodsy cabin doesn’t even have Wi-Fi. Not kidding.
But then I actually met my new stepbrother, Sam. And fuck… He’s totally hot. And into me.
Which is totally gross. Even if his abs are to die for. And his smile is amazing. And he’s good with his hands. And who am I kidding? He’s an adonis.
It’s no surprise that, after our parents’ wedding, we slipped up and ended up making out on the living room floor. Now I’m screwed. I’m addicted to his sculpted body.
And that was before I learned his furry secret.
Who would have known the beast between his legs wasn’t the only surprise in store?

I obey as if I’m under a spell. It doesn’t take long for him to figure out one of my secrets.
