She had no intention of keeping its existence from me. It’s just that wearing it as an outer garment would never have occurred to her. I was standin...g in her closet looking at what she has to wear. It’s a pretty disappointing selection. I gave up and turned to go back out into the bedroom and saw the slip hanging on a peg. I picked it up, went out, handed it to her and told her to put it on.I stood back and smiled as I watched her put it on without the slightest suspicion it’s all she’s going to.

I came quickly, not waiting for her, knowing that.
