The Sister’s Ordeal 1-2 (Etta)

In the extreme horror story "The Sister's Ordeal," sisters Etta and her two younger siblings have been sold into sadistic sexual slavery, with Etta broken after hours bound atop a wooden horse. The Slave Master forces her to accept a cruel bargain of more torture in exchange for oral servitude, while her horrified new sisters are taken on a facility tour and recount past terrifying encounters with the sadistic Morgana, including being locked in a pillory and forced onto a crushing plank. The livestream of Etta's ongoing submission plays in the background as a grim warning of total obedience.
