Hows your relationship with your girlfriend? Not going so well? Didn't think so. She had to go out and buy an array of dildos just to please herself because you weren't cutting it anymore were you? Then one day... she came home with a giant BLACK dildo. You couldn't take your eyes off it, could you? You were drawn to that giant BBC! No wonder you couldn't get it up for your girlfriend anymore, you want the BBC!
