Some ladies are a bit held back with prostate stimulation, especially on a first visit. Recently a new adventure at the Green Condo found me in a situation where the new Japanese lady was massaging my balls and continued to slide her fingers across my ass.
I lifted and enjoyed her teasing, but it wasn't until I verbally gave her the go ahead before she slipped on a condom over her finger and administered a solid prostate work over.
She seemed relaxed and experienced with the task and completed her services with a smile.
