When the fuck was Uncle Frank’s problem

Book is better in fact it describes how overloaded his body became with all the sensation. You don’t really get pleasure part from the movie but it’s kind of hard to display that aspect

his dad joe biden didn't discipline him

so is it actually evil or only evil if you try opening it to coom?

Well, there is that part in Hellbound where they let the Tiffany go because she didn't open it for that reason, but that seems to be the exception.

its not evil. they just deliver maximum experience. they're pretty neutral i think

Neither. In the book they are just beings from another realm all about ultimate pleasure. Basically why do some freaks get pleasure form BDSm, tattoos, body piercings, autoerotique asphyxiation. Second movie and every one after where cenobites turned into just generic demons from Hell

Coomer.

when Chatterer just stuff his fingers into her mouth
