In the days before I became a full-fledged cuck, my wife would tell me about her former lovers during foreplay, going into great detail about their fucking sessions, cock size, with the idea being that her telling me what a dirty little slut she was would turn me on. Ironically, it did, but not because of her necessarily, but because all the talk about her partners (especially their big dicks) would turn me on to no end. Unfortunately, this was in the early years of our marriage, and she had no idea of my bi-curiosity, or my fantasies to see her fucked by other men.
The guy she'd been engaged to for a couple of years before we met was supposedly gifted with a 10-inch, uncut cock, which earned him the nickname "Elephant Man", and she was so infatuated by his dick, she told me she even had polaroids of it next to household objects, coke cans, her little arm, etc.
You wouldn't believe how many times I went through her dresser drawers, hoping that she'd saved those fucking pictures!
