Susan was facing a metal post, her clamped nipples chained around it. Across the room was Christina, similarly chained to another pole. Each girl's long hair had been tied into a ponytail and threaded with rope. The ropes had been stretched across the room so the two ponytails were tied together, pulling the girls' heads backwards, increasing the pain in their nipples.
Rough hemp rope circled each girl's waist and passed down between their legs, spreading their pussy lips wide and digging into their tender flesh. These ropes, too, had been pulled across the room and tied together. This meant that in order to relieve the pain in her nipples, Susan had to move herself closer to the metal pole, which meant leaning her head back to relieve the pain in her scalp. It also meant pulling on the rough rope between her legs and inflicting pain on Christina, pulling her away from her pole.
The other woman, of course, was trying to do the same, looking for the most comfortable position she could find with little regard to what it was doing to her counterpart. That was the game and after two days of punishment, both girls knew they had to play it. Susan, at the moment, had the upper hand. She had grabbed the pole with her handcuffed wrists and pulled herself close to it before Christina had fully realized what was happening. It came at the price of straining her neck backwards. Once Christina had realized what Susan was doing, she had pulled her head down to eliminate the slack in the rope tying the two girls' heads together, despite the pain it caused in her own scalp. But as long as Susan was able to keep her grip on the pole, she was able to keep some slack in the chain tying her nipples to the pole.
Christina had spread her legs slightly, as much as she could with a chain tied around her ankles, and tilted her hips inward, using the crotch rope as a weapon against Susan, trying to get the girl to back up slightly. The woman didn't know how much more pain she could endure in her nipples as they were pulled to the maximum by the chain. She knew soon she would have to give in and let Susan have the victory.
Jacoby had grown bored of watching the girls. He had hoped for a struggle and had been surprised that Susan had moved so quickly to protect her own tits at Christina's expense. He walked over and tied a metal bucket to the rope tying the girls' hair together. They both groaned at this extra weight. He tied the rope for their crotches to the bucket as well and then slowly began filling it with water from a garden hose.
Each girl's head was now bent backwards behind them and Susan had to step back from the pole as the bucket pulled down on her hair and dug into her crotch. She let go of the pole and backed up, taking up the slack in her chained nipples until both she and Christina were as far away from the poles as they could get, their bare asses and pussies on display. It was the only position that relieved the incredible pain in their scalps.
Still neither girl submitted, the memories of the whippings still fresh in their young minds. Jacoby uncuffed each girl's hands from their respective pole and cuffed them again behind their backs. This let him add another bucket to the ropes tying the girls, causing them to step even further back and bend over even further.
