Slave FGO

looking for a very strict, merciless Dom/Domme who enjoys intense, ongoing torture and total control.
I want to serve as a permanent, always-available sex toy and hole only. I crave being treated like a cheap whore, forced to stretch and ruin my own holes, punished severely for any complaint, hesitation, or safeword. I want to be used whenever and however my Owner desires, with no mercy, no limits, and no stopping even if I’m crying or begging.
I’m searching for daily brutal commands, extreme stretching sessions, self-inflicted torture, and constant power exchange through text chat only. I cannot do any video, pictures, or voice — text chat only.
Are you the cruel Owner who will take full ownership of me, expand my holes beyond their limits through text commands only, and never show any pity no matter how much I suffer?
I’m completely ready to submit fully and obey every single order without question.
