The Stepbrother Distraction by Jenny Pineapple

Playing wingman to my gay stepbrother is not how I imagined spending my summer in Italy.
But Gabriel needs a distraction after a bad breakup, and I offer to step up.
Simple, right?
Except every man who looks at him irritates me.
Every smile he gives someone else feels wrong.
And the more time we spend together, the harder it becomes to ignore what’s happening to me.
Which is impossible.
Because I’m straight.
And wanting my stepbrother?
That sure as hell wasn’t part of the plan.
