The lady: Autumn Haze (bears a passing resemblance to Gina Davis with an unfortunate grill)
The "theme": Gangbang
The title: Don't remember

The anal moment in question iccurs near the end. Gina is atop a man on a couch, his dick in her cunt. Another male mounts her from behind and pushes his dick into her butthole. This is a common enough pornagraphic act widely known rather unimaginatively as "douple penetration" or "DP" to save time. Autumn Davis's reaction is immediate and clearly genuine: She cries out in pain and distress and her eyes widen in fear. By all appearances this seems to have been sprung opun her perhaps. Anyway, this is the only anal pornography I ever used the A-B function on my remote on. Looping well into the shitbox promised land of deviant margerine.

Little overbite. I liked her work.

Not just a simple overbite. It was more akin to John Tuturo jaw misalignment.
