This is a "female commander in military uniform captured by the enemy" requested by skeb.
Hmm, she was a woman in the request. However, when I finished it, I was obsessed with the thought, "Wouldn't she be very pervert if she were a shemale?" This is what I found myself doing.
I gave the female version to the client.
The sad masochistic nature of the shemale, whose penis is wrapped in a chastity belt with spines, and who gets an erection even though she would not have to feel pain if she did not get an erection, and who cries out in pain and suffers as her penis grows bigger and bigger...!
