Sue McBain what a wonderfully submissive slut she was. Never saw a cock she wouldn't take in any or all three holes. One of my all time favorite vintage porn scenes. Number one is the three way lesbian campfire scene in Dorothy LeMay's Nightdreams https://xhamster.com/videos/nightdreams-1981-8869195
that was the best blow job ever no hands just her mouth sucking off his big hard cock and his creamy hod cum in her mouth you can tell by the way she sucked his cock and ate his cum she was very satisfied with his cum.hell i would suck his cock and rat his cum and i am a guy.
I saw that in a theater with my future (and current) wife back in mid 80s. I think New Wave Hookers was other half of double feature. I got a handjob during an Annette Haven scene in Broadcast.
