This is the way it starts, one step in the process. Watch BBC porn, get the wife the BBC toy, have her talk dirty but its that comment from her "I want you to fuck me hard" that turns the tables. You can get in bed and fuck her, but shes now scene and felt what BBC is, when she says fuck me hard, she wants what you've shown her in the videos, not what you can provide. And thats when the next request comes to try for real.
