huh?? what "kind" of girl are you referring to?
Alexis does both vaginal and anal scenes, so what's the difference between a scene with two guys performing either vaginal or anal sex on her whilst the other receives a blowjob/handjob (spitroasting) and a scene where two guys simultaneously perform vaginal/anal sex on her (DP)?
it's not a massive leap to a DP scene, but I don't see how it only takes a certain kind of girl, considering she's done pretty much everything else going (apart from IR, which she's said she won't do)
