Posture is a great starting point for head strong, naughty pets. Especially bratty ones. It is also something he can teach long distance, of course it would require that you get a webcam.
Some common posture positions are:
1. Attention (standing/kneeling) - Back straight with your thighs, chin up, eyes forward, arms folded behind back, legs slightly parted.
2. Presenting your breasts (standing/kneeling) - arms folded under your breasts, upper arms pressing them together while your lower lift them. Back straight with thighs, chin up, eyes forward, legs slightly parted.
3. Presenting your ass (aka ass up face down) - Knees together kneeling, then bend over until your shoulders are resting on the ground, arms folded behind your back.
4. Presenting your ass flat - Legs slightly parted while kneeling, bend over forwards, arching your back as you do, until your thighs are just over vertical, arms should be spread to either side, perpendicular to your body. Your asshole should be "flat" to the ground (parallel in english?)
If I were him I would teach you 1 and 2 as part of a mental training exercise.
Example:
Some very energetic submissives, especially those who claim to be naughty (hint hint
) are also brats, and most brats suffer the same problem, lack of focus. When given a physical task they usually perform well, but when given somewhat deep questions, they are usually unable to focus their mind enough. Now, the art of asking questions is not something that you can just snap of fingers learn. It is something that is gained via experience, and starts to become more effective as top gets to know bottom, but it is important to D/S relationships.
Posture helps this first critical hurdle by forcing discipline while you are forced to think about your bratty-ness. I like to go a step further when using posture as a platform for questions by adding a pain element, usually via clothespins or clamps. The pain dulls all the "background noise" in the bottoms head, helping them focus on the top. I have found that it is most effective when the bottom applies the pins to themselves.
You warm up by getting the bottom into posture and start asking simple, general questions. At this point, expectation is that posture will be 100% perfect at all times. As you go, either finding a natural question point that fits it, or at a whim, start having the bottom apply the clothespins to their torso, make sure that the pile they are taking pins from is far bigger than they will need (ie. there are more clothespins than she/he will use). When pins are being applied posture can obviously relax, once they have been applied, posture should be resumed and maintained.
Once enough clothespins are in place, the questions get much harder and a reward system is put in place. Good, thought out, clear answers to difficult questions are rewarded by gently removing pins (choice of most painful, least painful or a specific one is up to the top obv.). Bad answers are punished by pulling pins off.
Have fun!
