Machines have instincts

Kata may have thought she was made for modeling more than for sex, but she also thought she didn't really like anal until she slid this pliable rubber dick comfortably up her ass. It was such a perfect fit that there was nothing but a pure instinct in the match... And if it were possible to say that machines have instincts, then we would have to say that the Sybian in our studios does pretty well in fulfilling its own. If natural selection had enough to do with it, then we have a feeling we would all be half-machines by now!
