Real real real, any size, A through DD.
I knew a girl who had one breast augmented because she had a significant size difference. I'm in favour of reduction to deal with back problems and such. But all other things considered, I'd prefer real.
Seeing a porn flick where the woman has huge hemispheres sliding back and forth on her chest as she gets fucked is sooooo unappealing.
Yea if it's medically needed like reduction I'm OK with that. Don't need someone having severe back issues.
