"Quantifying Sensory Response to Familiar vs. Unfamiliar Stimuli in Safeword-Free Tickling: A Case Study on Brianna Olivia"
Abstract
This study examines the physiological and behavioral responses of a restrained, gagged subject (Brianna Olivia, 23, UK) to tickling stimuli from two distinct sources: an unfamiliar lab director and her pre-acquainted friend (Kacie). Conducted at Fettishlabs under the "No Safeword" protocol, the experiment tested Brianna’s self-selected 10-minute tolerance while immobilized on the Tickle Table® and sealed within the Immobilizer™ body sheath.

Conclusion: Safeword removal intensifies vulnerability, but tickler familiarity significantly alters pain-pleasure dynamics. Skill amplifies physical reactions, while familiarity heightens emotional surrender.
