Speaking of actual pornstars (i.e. that do mainstream videos):
In no particular order:
Kendra Sunderland. First of I love the way she started (that library vid when she was a camgirl), then after some B/G she did a scene for blacked and was so hooked she cucked her real life BF with black men and eventually dumped him. She now claims she's black exclusive.
Emily Willis: Really beautiful and always has good energy in her scenes but especially IR scenes she seems to enjoy those much more.
Riley Reid: Same energy as Emily Willis.
Jia Lissa: I have a thing for Russian women anyways, so that's a plus...but particularly how she got into the IR scene is quite interesting: She was engaged to her Swedish boyfriend, when she was doing B/G porn already. She then said to him she wanted to do IR and he forbade her. She dumped him and made a video on her twitter looking for a black guy in order to practice with for her first scene. Obviously being in the porn industry finding exactly such a man with more than enough experience is hardly an issue, so I think she deliberately did it to piss off her ex and also entertain her fans.
Liya Silver: Whilst she hasn't really expressed an outright preference for BBC, she's known to have had a huge amount of sexual experiences outside of the porn industry (the details are a little scarce on this, but she was either a sugarbaby or in some sort of cult, she had sex with Asian men, arab, cuckolded many of them doing IR etc). During covid she was stuck with Jia Lissa in Bali (and some others) and obviously didn't make any professional scenes, but a particularly interesting video was when they where filmed talking to some black pornstars and they where begging for them to show them their cocks. A little while after that Liya was partying with an older russian friend of her (not a pornstar) and she had a QOS tattoo on her ass.
Katrina Jade: Did a lot of IR in her private life and even with some members from here. She was actively looking black men up to hook up with an advertise on her twitter.
