I could totally be a smart fuckdoll.
Had an ex who was a makeup artist/costume person. Hella smart.
But when she wanted to do "fuckdoll", she could totally transform herself to dial up the ultra-femininity.
She could do the bimbo cleavagey sex bomb or do the latex rubber-doll version (if we were going somewhere that was appropriate) and just kill the room.
But it was a short-term bimbofication. It was a look she put on because getting all dolled up and turning her considerable brainpower and talent to being a fuckdoll for the night was something that turned her on.
When people usually talk about the fetish they mean the full-scale body transformation and very often a turn to deliberately rejecting their smarts.
I'm not into that, but tapping into the ultra-femme because you've got control of it and it is a power you want to play with?
Hot as fuck.
