Feels scary how it would be possible to break a person with a perfect VR prison. Put them in a VR room, all senses are under control, create a sexual partner (human/monster) that will fuck them until they break. Costant stimulation, hitting just the right spots, maybe even change the smells and taste of semen into something they would like, even more in a accelerated time prison with nothing to do or eat aside getting fucked. Then when they are broken you lower the stimulation slowly and change the taste and smell to the real ones, release the victim from the prison and have a "voluntary" cumdump that will seek out sex.
