^lol you're obviously a noob who has never felt fake tits before.
The majority of fake tits aren't hard. They're just firmer and less squishy than real tits. It's like comparing regular spaghetti to al dente. There are some hack jobs out there and what you pay for is definately what you get but all in all there's nothing better than reaching up and grabbing a nice big fake tit while you're eating a girl out.
I think all women should go and get fake tits. They're the best!
