Suggestions: sneaking around but for grown ups

I'm looking for recommendations for tropes and books that fit the theme of, "having to sneak around in order to be passionate." I loved this trope in YA fiction and I'm struggling to find adult equivalents to it. I absolutely loved the chemistry from {Love and Other words by Christina Lauren}. The feeling of exhilaration when the dad is gone and the teens in love are left to steal the few moments of passion that they can take 🥵🥵🥵. Maybe they're camp counselors at a Christian summer camp, maybe it's the best friend brother at the family reunion. I'm open to all genres as long as there's smut. I also listen to books on audio. Thank you for your suggestions!
