I hope this hasn't been mentioned here yet, especially by me.
The scene is with Adria Rae and Markus Dupree at Tushy Raw called "My Anal Obsession." After Adria has her ass fucked for a bit on her back on a stool, she flips over to give better access. Starting around 19:20 Adria takes an anal pounding in this position for around six minutes straight.
Sarah Banks gets her booty impaled in doggy and missionary on a stool in "Big Wet Butts - Just Jeans". Nice long strokes until he's hammering her balls-deep.
I watched an older scene with a model I still watch regularly. It's Kaylynn. The scene is in Jules Jordan's "Flesh Hunter 7." Kaylynn is paired with Lexington Steele and once the anal starts, there is part of it where Kaylynn is on a raised chair with her ass sticking out as Lexington pummels her bum.
Sheena Rose in "Deep Anal Action" with Mike Adriano. Starting around 30:50 Sheena is backwards on a reddish leather chair and teases the camera before Mike steps in and starts fucking her ass in this position.
I don't have a lot of scenes with Sheena, but I can say that this one is great.
^^ I'll mention that Private's Kick Ass Kitchen DVD series went to four volumes. I'm not sure if every scene in the other three movies featured this as well, but a quick look seems to indicate that at least several scenes did.
This is from the 2019 TushyRaw scene for Gabbie Carter called (appropriately!) Bounce Bounce! Up until this time I'd always been transfixed by Gabbie's amazing boobs. Suddenly I discovered she'd also got an unbelievably gorgeous tight ass! I just love this pic. You get full value for a her boobs at the same time seeing that gorgeous ass getting penetrated! OMFG!!
Similar pose from Gabbie in this pic for a Jules Jordan scene. Not quite as nice a photo but you can still see her gorgeous boobs and that ass. This scene was called: '19 year old teen Gabbie Carter takes it up the ass' in 2020. The main difference from the TushyRaw scene was that this time she had Chris Diamond pounding her ass with a dick around 50% more girthy! In my opinion this was the roughest scene she ever did and got really fucked hard. Gabbie went on to take Anton Harden in an anal scene for Blacked but that was much more sedate!
