It's only a matter of time, now that she's had a taste of just how good a big cock (be it only a fake one) can feel inside her little married pussy. As time goes on her craving for a big cock will increase to the point where she will have to sample a real one, but rest assured that once she does it's not going to be a one-night stand, she's going to want it on a regular basis, so prepare yourself for a massive sexual change to come over her in the not to distant future.
