The objective of Paul's depraved experiment? He was simply insatiably curious as to how an unwilling, heterosexual male would cope – psychologically and physically – with such a relentless sexual onslaught. How long exactly? Neither Paul nor Rick could decide, but in the end they agreed to leave their victim to be perpetually ‘spit-roasted’ overnight and decide in the morning whether to let the experiment continue or not. A sort-of ‘sexual experiment’, if you like: kidnap a random straight guy, secure him in place between two fucking machines, front and rear, and leave him to be orally and anally violated by two large dildos mounted on the machines, without respite, for as long as possible. Of course, he couldn't have pulled it off without Rick's help, though it was Paul's idea in the first place.
