I don't like fake tits. But it's all in the mind I guess.
A good looking woman with nice tits that has her clothes on might turn me on. But once she takes her clothes of and I see that she has these plastic tits... cold shower, game over.
Even when it's a job extremely well done where you can't see it and believe they are natural. Can make me horny. But once I know they are fake - could be that I sudenly notice, that she tells it, that I feel it when I touch them, etc - it's over. I don't mind that tits might look 'not perfect', but I like the real deal (or as close as possible).
All these chicks with fake tits, fake lips, fake eyelashes, a fake ass, fake nails, etc, fake moaning, you might as well jerk off looking at a tree.
