Saki is owned by Tryst, but not in the way that a BDSM slave is. Instead, Saki is Tryst's pet, which means that he is under Tryst's protection, is played with by Tryst, and is supported as he grows as a person. Saki enjoys the kind of bondage and extended scenes that Tryst likes to mete out, and is happy to be wrapped in rubber, casts or foam for many hours.
To symbolise Tryst's ownership, Saki has an NFC chip implanted in his left hand, programmed with the URL of this website, which Tryst controls. Tryst has set a password on the NFC chip so that nobody else, Saki included, can change it.
Please treat Saki with love and care. He is a good possum.
