mine fit into three categories (though if i thought about it for longer i could probably come up with more)
1. softcore models i have been obssessed with who never went hardcore, and certainly not the kind of hardcore that appears here. an obvious example of that is Caprice (and i suspect many members here will read that and sigh and say 'ahhhhh yes, i remember Caprice'), but there are lots of others
i suspect fans here who always wanted softcore models they followed to shoot hardcore is not an uncommon desire that falls under the thread title here
2. bondage models i have been obssessed with who never shot hardcore is another of mine. Nyxon is my favourite bondage model of all time (closely followed by Emily Addison). to have seen either of them tied and fucking hardcore would have been a dream come true for me, but there are depressingly few bondage models who ever cross over. they are two entirely different dosciplines, and models attracted to shooting one rarely move into the other (though kink com did superb work in shooting the few who did)
3. (related to 2) being a bondage fan and a latina fan, i've always wanted to see my favourite Natasha and Lancelot models mixing serious bondage (not play bondage with furry handcuffs) with the maximum hardcore performances the models from the studio deliver so well. i still secretly (ok well it's no secret anymore now i'm writing it on the forum!) want to see it but i think it highly unlikely, so am not expecting to ever see such a thing
but i suspect some future colombian studio will notice that there is a bondage and hardcore crossover niche that no one is catering to at the moment, and move in to make it their own (a latin=american kink com), so i remain ever-hopeful (even if not genuinely optimistic)
my first thoughts on the topic anyway
