Baby with my Brother's Best Friend: A Forced Proximity Enemies to Lovers Romance (Babies with Billionaires)

I absolutely despise my older brother's best friend but that didn't stop me from sleeping with him. I spent ten years avoiding this jerk and then he shows up to my brother's engagement party. I never expected an explosive argument between us to lead to his tongue in my mouth, but those ocean blue eyes melt me like butter and his chiseled muscles make him impossible to resist. A drink spilled on my dress becomes the perfect excuse to remove it and do something totally reckless. What the heck am I doing? He's so much older than me and I'm supposed to hate him, so why do I love it so much when he touches me? I guess there's a thin line between love and hate and now two little pink lines could determine our fate.
