You mean, never talking, even before you have sex? As in, just seeing a hottie, nodding at each other, and getting freaky?
I don't see this as a possibility for myself. I mean, yes, I could absolutely do it, say I go to an open minded club, the music is all loud, I start dancing with this smoking hot chick, she's all grinding her ass into my crotch, I get hard, she starts feeling on my package, her facial expression is saying "Feels like you've got a nice dick in those jeans!" She unzips me, pulls my dick out, drops down and starts blowing me on the dance floor, I pull her up, spin her around, lift up her skirt, rip her panties off, and just start railing her from behind...,
Then, her boyfriend comes back from the bar and clocks me in the face, leaving me knocked out on the dance floor with my hard cock laying across my stomach. Fantasy over!
So, yeah, I would do that shit in a heartbeat, but realistically, I don't see it ever happening. I just don't go to those types of places.
