Be adventurous with your bastinado. Strike the whole sole. Some places harder than others to ensure safety

The balls of the feet are the most common target for the bastinado. Very painful.

Striking the insteps is important during bastinado. It is extremely painful and a real challenge for the victim to endure.

The heels are also a great target and very painful
 

Simple Bastinado Routine

Your bastinado victim arrives at your house. You determine if a safe word is to be used and progress into the session. He stands in the centre of the room and allows you to strip him naked. His hands are tied tightly behind his back and you push him down to the ground. You sit down in a comfy chair and your victim drops to his knees and removes your shoes and socks by using only his mouth. When you are barefoot he spends the next 20 minutes kissing and licking your bare feet. He begs for you to punish him and respectfully asks for the bastinado. Your victim is laid on the floor and his soles tied to a spreader bar at waist height. You ensure that he cannot move his soles away from your attention. Using a leather belt you deliver 30 strokes across both the soles of his bare feet. The belt should impact all areas of the bottom of his feet including the balls of his feet, the insteps and his heels. The strokes are given moderately hard.

After a short rest you again deliver 30 strokes to the soles of both the bare feet using a lightweight cane. Each stroke is given decisively with a short pause between strokes. The cane is carefully aimed to ensure that the entire sole receives a fair share of the action. Maybe 10 strokes to the balls of the feet, 10 strokes to the hells and 10 across the instep.

A 5-minute rest is allowed.

Once again using the same cane each sole is given 20 strokes. This time the cane is lashed down very hard across the soles. The victim counts aloud each of the strokes. He should count aloud as follows: “1 Sir, thank you Sir”, etc until all 40 strokes have been delivered. A miscount by the victim or a pause in counting will restart the 40 strokes.
The feet are now tied together ankle bones touching, the soles waiting side by side for the final whipping.

Both soles are now struck at the same time. You deliver a final 20 strokes across the soles using a much heavier cane. If the victim agrees the final 5 strokes could be given with electric cables. The session ends with the victim being untied and reunited with his clothing. Maybe at this point you change places and bare your own soles for him to deal with in a similar fashion.
