Most of what is in that link is more or less what I’d say myself.

With a few exceptions.

Hands and feet. Nuns never have a problem hitting the mark with a little stick. lol Bastinado is quite fun. When I have a guy on his knees and his feet are turned up, they’re fair game far as I’m concerned. You don’t have to worry about your aim in this position because it’s already on the floor. The surface of the floor will prevent wraparound. Likewise if the person is on a bed. Just be careful of the tendon behind the heel.

I mostly do a moderate swipe or two now and then, realizing they have jobs and have to stand and walk. lol But if someone wants a more harsh treatment, I’d be perfectly willing to give it to them. I have numerous implements that would suit, including canes, coaxial cable, paddles and several kinds of flogger.

Kidneys…this is going to depend on the person and their own tolerance and the implements used. Coaxial, yes, I’m definitely going to be very careful where I strike. But a regular ol’ flogger on a big boy or big girl isn’t so much a problem. If they have layers of fat around the middle, that’s going to insulate the kidneys, and gives a wider range to flog on without as much worry. I can employ more follow through and really drag the flogger down their back in the swing.

How small is too small? How big is big enough? Talk to the person while flogging and ask. People I play with know I expect them to answer me honestly. If they don’t, I’ll never play with them again.

Breasts and more care. Eh. I’m just finishing up healing from a breast paddling I took two weeks ago. If the bottom understands what they’ll have to deal with after, and for how long they’ll be dealing with it, how much more care is rather up to them. EW will flog my tits just as hard as he does my back. The “care” he takes is to not misfire and whack me on the neck and face. lol And I take care as well, and use my arms to cover and take any errant swings. No one is perfect. Taking tails to the ear is a hazard if one wishes to be a whipping post. lol

She doesn’t cover canes, but I have a lot to say on those too. lol

Using a pillow. Absolutely. But I go a bit farther in telling a novice flogger wielder to have someone lie on a sheet on the floor. Trace their shape in marker. Note the elbows, the knees, the ankles, mark the soft tissue below the ribs. Then drape the sheet over the bed with a couple pillows under it to approximate a shape. Drape it over the comfy chair to see how everything changes. Drape it over the back of the sofa (one of our favorite places) with the pillows.

Hope this is helpful.
