Slippery when wet

Jo's fingers slipped across my ass, baby oil catching the sunlight as she worked the oil deep between the cheeks. Her hand moved slow, almost reverent, cupping and parting. Then a finger found the tight ring and pressed, slick and certain, sliding inside with a quiet ease that made my breath catch. She fucked me like that, one slow stroke after another, and the lube dripped warm, running down until everything glistened. I knew the other side of the phrase had never felt so literal: slippery when wet.
