Part One. Lower Extremities
Shaving must be done in a bathtub.Showers waste water and may inconvenience your Mistress. Remember, there is much cleaning to do afterwards.
Use only high quality women's razors, as men's razors just won't do. DO NOT use anything that resembles an electric device. (We will speak of epilation further in this course of study)This is doing a disservice to your Mistress, as she requires a smooth skinned sissy. Not a stubbly one.
A soaking is required for a minimum of 10 minutes to soften the hair and skin, thereby allowing a smooth shave, and allowing your skin to remain intact.Since you have 10 minutes available, this is an appropriate time for your Mistress's pedicure.
Work soap into a foamy lather, and apply liberally over the area of attention. Do be sure to not apply in areas not planned for immediate shaving. DO NOT allow your razor to touch your skin that is not properly prepared.
Hold razor gently between index finger and opposing thumb.
Start at your toes, moving up to the tops of the feet taking extreme care over the anterior tibia and ankle. Be sure to clear
ALL hair from legs, feet and thighs.
If this is your "first" time, shave in the direction of hair growth first, and then in the opposing direction after relather.
The backs of your thighs require the technique stated above (see #7). We recommend multiple directions after relathering.
Do take care behind your knees, as the Mistress has no time for caring for your wounds.
Do not forget your behind. This is always call for much correspondence with Our Staff. It is imperative that this rule be followed. There is nothing worse than a sissy with a hairy ass.
