Beginning Slave Training:
First, increase the slave's "exposure." She must learn that this area of her body is not off-limits to her MASTER, at any time. This can be achieved in many ways, simply by touching and looking. Whatever method you choose should somehow involve the submissive's attention on what she is doing (exhibiting the most private area of her body) and why she is doing it (why she must make everything available to her MASTER'S whim). Instruct the slave to focus on both simultaneously.
Here are some suggestions for the beginner slave:
Have your slave assume the knee-closed examination position on a piece of furniture or the bed (this position is better than the knee-open exhibition position). In this position, your slave knows that you are behind her and watching her.
Keep the slave in this position for a while. If she seems too comfortable talking to you, remain silent, and vice versa if she's more comfortable with silence.
At a certain point during this position, you should order her to use her hands to spread her buttocks. Depending on the slave's state of mind, you can gently encourage her or harshly insist that you need a "better view."
Find other opportunities to increase the slave's "exposure," such as random inspections of only that body part; watching the slave bathe or observe her using the toilet; adding anal training to punishment or sexual acts (i.e., having her remain open while standing still in the corner of the room or while you are using her from behind); or including cleansing rituals in her duties.
The first act of "insertion" should be with a lubricated finger covered with a condom. Even if your slave is familiar with anal play, start this way.
An effective position for this approach is to place the slave over your knee as if you were going to spank her. This position is very intimate; the body contact and proximity serve to make the act more moving and profound.
Watch the slave's face (you may have to insist that she turn her head so you can see it) to see her reactions as you examine her. Is she in physical pain? Are there any emotional warning signs? Is the discomfort greater than she can handle, or is it exactly what you want her to feel?
If you enjoy humiliation, suggest an enema next time. (Don't do this, however, if this is the slave's first experience—don't "play" by applying these types of shameful actions in the initial stages of training.)
If your goal is to increase the slave's capacity for sexual service, hold your finger and have her squeeze and relax her muscles, or simply encourage her until you feel her relax as you move it in and out.
