Drunk on Starlight

Story doesn't belong to me. It's from Ao3 author Teicakes.

At first glance, the Lion's Den is exactly as it appears: a high-end nightclub for top ranking Galran officials to kick back, relax, and watch human companions perform acts from their wildest fantasies. But behind all that lies a deeper purpose, and a resistance hell-bent on using every last vice of the government to bring it down from within.

Shiro, Keith, Lance, and Hunk make up the core of Kolivan's front team, genetically bred companions rescued from being sold and instead working to woo even the deepest of secrets out of lust-crazed officials. Now there's a plot to destroy everything they've worked towards, and the only chance to save themselves is landing one of Zarkon's right hand men in their pocket. But there's also another Galra, one Shiro keeps running into time and time again, one he can't help but feel like there's more there than meets the eye. One who, unlike the others, is one he can't wait to see every time. One who, despite Shiro's best efforts, might be winning his heart.
