I don't know why u brought lima into it, but since u did yes she was, she even spoke in english on the phone about her price for "deepthroat" and "bdsm" ...
But i don't think irma is like lima, at least more "soft" before alex only watched he couldn't touch anyone ... now things have evovled i'd say ...
And i'd like also to remind you that the first time that stella met alex, he told her about "prices" like iphone against naughty pictures (like irma already does with him)
