In a post-apocalyptic world, Lorelei and Felony are nurses of a special kind. The duo find weakened males and bring them to their underground lair, where these latex nurses use their charms to perform experiments on their “patients”.
These twisted nurses test their subject’s reaction to changes between pleasure and pain. To perform their experiments Lorelei and Felony first give their patient pleasure, with blowjobs, handjobs, and anal sex. But then the nurses change tactics, with CBT and using their coffin dildo machine to subject their patient to anal sex. Their results are again inconclusive, so the search for another patient will be necessary.
