Name of that vintage pornstar

I saw a movie where a mommy go to a party, but she discovered that it was an orgy. She looks what happen, but didn't participate.
After that, while sleeping in her bed, she gets horny and goes to see her son in her room to suck him then fuck him.

She has wavy hair and a nice pair of big natural breasts.

I thought it was Kay Parker because the actress looks like her, but either I can't find the movie or it's not her.

Can you tell me the name of the actress or the name of the movie?

If necessary, here is a link to view it :

thanks !
