Say You Want It by Jenika Snow

Piper: It was supposed to be a summer job, something to help me transition from graduating high school to starting college. But to me, this wasn’t just some office cleaning position.
I’d be working for Zane, the one man I’d loved for longer than I even wanted to admit.
The one person who could make me weak in the knees with just a glance.
My father’s friend who was far too old for me, but sexier than sin.

Zane: I hired Piper to keep her close, to help appease my need for her. But I played it off like I was helping her earn some money before starting college.
I was too old for her.
She was too innocent for me.
She was my friend’s daughter.
Off limits.
But I’d wanted her since she turned legal last summer. I saw the way she watched me, the way she bit her lip, the fact that her pulse jumped at the base of her throat when I was near. Did she know how obsessed I was with her, how I’d go to any means to keep other men away from her?
I could see how much she wanted me and that was dangerous.
Because her need for me made me territorial, desperate.
Everything I was, everything I had, belonged to Piper.
All she had to do was ask and it was hers.
