Rachel and Ken in Hell m/f, eternal torment

Rachel woke up in a room, at leas she thought it was a room. It was dark, small and dirty, something like a small basement room in a rundown building.
She clearly remember her torture from earlier and was fearful of what would come next. Then she noticed another figure in the room. It was her brother. She looked into his eyes only to see actual human eyes, he was not another demon. Both of them were naked, and they rushed to embrace each other, but unseen forces siezed them and moved them into position. They bent Rachel over and placed her on all fours, her ass in the air. They moved Ken behind her on his knees. This sight caused Ken to get hard, desiring his sisters pussy, even though they were both dead and in hell.

He was moved forward by the forces and his cockhead touched his sisters pussy. Her pussy lips opened to accept his cock, and he was pushed forward by the forces and into his sisters pussy. It felt wonderful and he fucked her with wild abandon. She pushed back with all the excitement he had. Both hoping their torment was over. His climax caused her to cum all over his spurting cock. Normally he would go soft and they would cuddle, but he was unable to move from that pose, his erection still strong, and was forced to keep thrusting inside his sister.

She was simalarly unable to dislodge him and kept pushing back. Again and again the siblings were forced to cum. Each time it was less pleasant than the last. Eventually they grew to hate it, yet they could not stop. A demon laughed as he laid bricks to wall off their prison. They were left to an eternity in a windowless, doorless, dirty cell were they were forced to fuck, constantly, having long moved past hating it. Both of them prayed for death, darkness, an end to the torment. But they had been damned by God, and their prayers would go unanswered.
