My life as a slave

My Master is 67 years old, I am 28; he is my owner, proprietor, he assumes power, controls absolutely everything in my life, administers absolutely everything, decides absolutely everything. I signed a slave contract with witnesses in front of other people, naked with a collar, wristband, ankle cuffs, chastity belt, in a country house, and the following week I was already prepared to sign legal documents before a notary. During the week I was already prepared to live in an apartment where Master decided, naked with a collar, wristband, ankle cuffs, chastity belt, where Master would have the account, cards, keys to where I live; there Master would have the main room and I a room for slave, mattress on the floor. He also made clear to me that whoever Master wanted would come, they would have keys to the apartment, I would serve, obey, be treated absolutely like garbage, shit, contempt, degraded, absolutely thank him for being treated that way. He left me there, took my bank account, bank card, key, password, saying I don't need them. He told me: I want you from work to home, because I work in a dried fruit factory on shifts. When I arrived from work there was a man about 65 years old sitting in an armchair; he starts insults, humiliations, tells me eat my cock, swallow everything while he hits me; I start eating cock; then he puts me on the table, whips me with the belt and fucked me; when he finishes he sends me to prepare food for him. When I prepare the food for him, he is eating, he tells me: imbecile, shit, come because I told you your owner put cameras all over the house and that you serve me, have you understood, imbecile.
