I Like the feel of fingernails tickling my bare skin

I played doctor, which was commonplace in my day, with many boys ai girls. Besides the usual facets of the exam, my patients lived having me run my fingernails up and down their backs, bottoms and Thurs. Many would break out in goose bumps and shivers as I tickled.
Very few of my games were in a group. Being in private, I had more freedom and both my patients and myself were more relaxed during the exam.
