I glanced down at my lap, twiddling my thumbs. “Y-yes, Doctor Aiden, I was meditating and I-I focused on my breath like you taught me—” “Why are you lying to me, Ivy?” My head snapped at him. “I-I am not lying.” Aiden tilted his head and my throat went dry when he said, “Then why did I hear your voice moaning my name when you orgasmed with your fingers inside you?"

I shouldn't want him. Not only is he cocky, arrogant — he's the bane of my existence. Yet when he touches me, it feels like I'm the most precious thing in his life.
