A few minutes ago, Cheryl mentioned that we sometimes play with a letter-opener. That's the one, there at the left. Beside it is my favorite knife. Toy #3 from the office. I guess you can see that they're just about the same size. Lotta difference between them, though, a lot...
Anyway, here's how we play with the letter-opener: I have her in some good position, say lying flat on her back with her arms up over her head, I'm holding both her wrists with one hand and I've got the letter-opener in the other. I'm on top of her, and I look down into those blue eyes and I hit her, maybe say between the ribs, maybe in the belly, with the point of that letter-opener.

Now, of course, I don't hit too hard. Not hard enough to break the skin or anything like that, but hard enough, hard enough to leave a little bruise sometimes. Way I do it, once I feel the hit I let my hand slide down over the blade so it ends up laying flat against her. Get the picture?
