The Boss by S.H. Azanon

Starting over in a new city is hard. Falling for your straight, engaged boss? Disastrous.

Fresh out of college and eager to prove himself, Chris is ready to take on his first real job. But he never expected his boss to be the real challenge. Powerful, brooding, and devastatingly handsome, Zac is completely off-limits—just months away from marrying the perfect woman.
Zac has spent years building the life he always thought he wanted. His business is thriving, his wedding is set, his future secure. But from the moment Chris walks into his office, everything changes. There’s a spark that shouldn’t exist. A chemistry neither of them can ignore.
Desire ignites. Lines blur. Temptation turns reckless. And as the wedding draws closer, both men must make a choice: play it safe and lose the one thing that makes them feel alive… or risk everything for love.

This is the third entry in the Straight Men series, but each story can be read as a stand-alone with no cliffhangers. Themes include age gap, first time, bi awakening, straight-to-gay, and gay-for-you (with plenty of Queen references, hints, and innuendos).
