Mutual Desire by Insyndia Strike

He was supposed to be off-limits. But some temptations refuse to be ignored.

When Damien gets roped into helping his best friend with an important work project, the last thing he expects is to collide—literally—with Russian billionaire Alexander Nabokov. Cold, magnetic, and devastatingly handsome, Nabokov is the kind of man Damien knows better than to get involved with—especially when Damien already has someone waiting at home.
But Nabokov isn’t used to hearing “no.” And what begins as sharp-tongued banter quickly spirals into a dangerous game of seduction. A game that threatens not only Damien’s heart, but his best friend’s future.

As the lines between desire and reason blur, Damien must face the one truth he’s terrified to admit: resisting Nabokov might be impossible.
A slow-burn, forbidden attraction romance filled with tension, emotional depth, and undeniable chemistry.
