Resisting the Best Friend’s Sister

I’m screwed.
Pippa just showed up uninvited with plans of staying the weekend.
I can hardly handle an hour with her, let alone two days.
Despite more than a year of dodging her, nothing has changed.
She’s the only woman I want.
Smart and sexy and bold.
My best friend’s little sister.
Forbidden.
Denying my desire for her is torture.
And she doesn’t make it easy; she wants me too.
The thing is, making her mine will destroy my best friend.
