I like chicks who eat ass

[Ms Remy M]

I know in tgirl porn I usually see more top girls eating ass...idk why

well, watching brazilian porn where most of the girls are tops, seems more or less the girl eating the guy ass before penetration is a form of dominance

Porn is hardly the barometer for reality. It's all just about selling a fantasy, the closest exception I'd acknowledge is with solo site girls who tend to film what they actually like. So if anything that is what you should base it off of from porn.
