Eliza Moira and Devon have been claimed but this is an addition to what has been suggested. It's a believable way to get one of the girls involved on the torture and killing and even eating another girl without making her become weird or sadistic. Sorry if this is long. It needs three people and works best with Eliza Moira and Devon because they are all close family. You will see why. The men set a mini game show for the three girls. They explain to the girls this is an elimination round and at least one of them must be "elimited" for any of them to move on to the next round. The girls have no idea what that means and thinks it will be a fun elimination round of the contest. The men explain to the girls that because Eliza is the oldest she will move onto the next round while Moira and Devon will be put through a series of trials and it will be up to Eliza to choose which one to save as the trials get more difficult. Eliza starts off saying she can't choose between her sisters but thinks this is all part of the game. Then the men gradually do worse things to Moira and Devon until Eliza cracks and makes a choice to save one of them.

The men strap the Eliza into a chair and tie her arms tied to the armrests so she can't move. There are two buzzers close to her hands that she will use to select which sister to "save". The men strap Moira and Devon upright into holding structers with a light above them that will turn on when one is selected. The men start off soft by tickling Moira and Devon and other light things that do not let the girls know their intentions. After some light foreplay the men begin to fondle Moira and Devon over their clothes. The girls attitudes change. Eliza yells at the men to stop. The men remind her she must choose which one to save. The men get worse by lifting Moira's and Devon's shirts, pulling thier pants down, rubing them, kissing them, licking them making Eliza more upset. The men remove Moira's and Devon's clothes all the way cutting them off with a knife, insert fingers, other objects and rape them making Eliza even more upset. The men bring in devices to begin torturing Moira and Devon gradually increasing pain on them. Moira and Devon are begging Eliza to save them. Eliza finally cracks and presses the buzzer to save the youngest Devon. Eliza protects her baby sister. The men escort the sobbing Devon off the rack and tie her in a chair next to Eliza for them to watch Moira get tortured. The men increase torture on Moira who knows her sister chose her for this. Eliza is appologizing to Moira the whole time. Before the execution Eliza is given a chance to change her mind like in game shows. The men announce the sudden death round and grab Devon from the chair. They lower the back curtain revealing the cooking and boiling devices mentioned before. The men put both Moira and Devon into the devices and give Eliza the chance to change her mind. The men tell her that both Moira and Devon will be killed if she doesn't decide before the count down timer reaches zero. After agonizing her decision with moments to spare Eliza buzzes to save the yongest Devon again and while sobbing appologizes to Moira who realizes her fate is sealed. The men release Devon from the device and tie her back up in the chair next to Eliza to watch Moira get executed. Cook or boil Moira. She dies knowing Eliza didn't choose to save her. After Moira is done the not shocking twist is Devon is going to suffer the same fate next. The men grab Devon and torture her then cook or boil her while Eliza watches. An optional plot is to force Eliza to eat Moira's cooked or boiled body in order to save Devon from torture and execution. The men lied and execute Devon anyway. Last Eliza suffers the same fate as the other two. None of them move on to the next round. Is this ok?
