As much as I love Mandy's anal scenes (especially when she's at her thickest), this is the one thing I wish was different - I do like to see a girl getting genuinely fucked (or fucking the guy) hard enough that you can tell she's pushing her own limits, especially when it's an anal scene. Mandy has a couple of these where she actually seems like she's getting pushed hard, but I really wish she had more such scenes.
She could definitely be doing harder 1-on-1 anal scenes. More scenes with guys like Richard Mann, Chris Diamond (back when he did US porn for a year or two), Brickzilla or even Dredd (despite me not liking his filming style most of the time), where we're talking balls-deep, maximum intensity anal.
It's interesting that in the intro to her ItsAnal scene 'PAWG Mandy Muse Comes By For Hard Anal Fucking' she categorically says she prefers dicks that aren't too long for anal, because when they're too long, they get too deep and says something along the lines of the dick getting into her colon, which she's not a fan of. Now that's the kind of thing I actually would like to see Mandy do more, not less of.
