Two Billionaires Next Door

Ethan
I'm a pompous, entitled, prick who happens to be a billionaire. I keep women at a safe distance.
Except for the ones my best friend, Zack, and I hook up with.
Yeah, we like to share one woman at a time.
Zack's father dies, and as he closes out his father's affairs, Mindy shows up and upsets the balance.
Mindy is not like any woman I've ever met before. I can't trust women to begin with and am even more suspicious of one who wants nothing from me.
Until I begin to need more of her.

Mindy
I haven't seen my old next door neighbor, Zack, in over seven years. His dad dies, and he shows up to tie up loose ends. Except he's now a billionaire. His proposal of a no-strings-attached hookup with him and his best friend, Ethan, is right up my alley.
Until I do what all single women looking for love do at one point in their lives...I fall hard.
Twice.

Zack
Mindy is the one who got away. I see her near my late father's house as I'm taking care of his affairs, and I'm hooked again. Except now, I'm different. My best friend, Ethan, and I like to share one woman.
Mindy likes the idea of a casual thing with both of us.
Until I decide it's no longer enough.
