Rachel, the local librarian, had a student at her house for tutoring. He was studying anatomy with her. He had a lot of questions about nerve endings, so she agreed for him to test different sensations on her body. He suggested tying her up, she reluctantly agreed. He then told her the test would be a tickle test. Rachel jumped at the first touch of his hand on her foot. He went up and down her body exposing her panties as she squirmed. She began cussing and told him he was turning her into a trash talking librarian. He pinched her knees, tickled her thighs, the soles of her feet and in between her toes. Rachel was screaming and laughing at the same time, she even let out a snort. He kept tickling her until the next student arrived. That was the most laughter Rachel had since she could remember!
