Probably one of the "Devil in Miss Jones" sequels, for the Devil's cum shot he pulled out & away & shot fire out of his cock like a flamethrower...

Yeh, it was obviously a fake dick, they didn't exactly break the bank on sp fx, but still a definate "WTF" moment in porn...

There was also a cheesy "Star Wars" porn parody involving a woman sucking off a C3PO unit, but not quite so much as the "DMJ" scene...
