Something my girlfriend caught on late night TV ~15 years ago

[ids]

My girlfriend saw this years and years ago on some late
night tv channel. Her birthday is coming up so I am trying to hunt it
down for her. Below are the only details that she remembers -

-a glowing rock that makes people have orgasms then explodes when touched
-possessive pillow who gets jealous of it's owner having other people in bed

I have googled every thing I can think of and asked around. People
claim that it sounds familiar but no one can name it. Any
ideas?

The Fear Chamber has a glowing, mind-controlling rock in it, which explodes at the end.  Don't recall a jealous pillow.

What immediately comes to mind with your first clue is Sleeper, starring Woody Allen.

Don't know about the pillow, but the rock brings Killer Tongue to mind.
