If this is not porn, I do not know what is.
This film is explicit, to say the least. It includes more than a few full-frontal shots of the fella. Basically it is about what used to be called a sex maniac (but female: she cannot get enough of it) who gradually realises that sex can actually be enjoyed between two people in love (remarkable!).
They certainly enjoyed every moment, and if you like watching this sort of thing, so will you.
But kids, do not let mom and pop catch you watching it. And mom and pop, do not let your kids know you watch films like this.
