bondage slut
Someone who enjoys or engages in sexual activities involving bondage. It typically refers to a person who willingly and enthusiastically takes on the submissive or bottom role in BDSM scenes or relationships.
A bondage slut derives pleasure and fulfillment from being restrained, tied up, or otherwise immobilized during sexual play. The term "slut" is often used playfully and consensually within the BDSM community to signify a person's enjoyment of and willingness to explore their sexuality without shame or judgment. It is important to note that any sexual activity, including bondage, should be practiced responsibly, safely, and consensually between informed, consenting adults.
