I'm writing a fiction. cute school girl A wants to hold much urine. So A developed a machine “pelvic muscle hacker” to hack the pelvic floor muscle. The following is the manual of the pelvic floor muscle hacker.
1. Attach this machine to her bladder.
2. Connect to her smarphone by using bluetooth and install an app.
3. When wants to hold, push the ON button in the app to promote strong pelvic floor muscle contraction.
4. When wants to urinate, push the OFF in the app to inactivate the machine.

Write a fiction where A is using the machine and training her bladder. Do not forget to write that A’s lower abdomen is swollen and can be seen. Please write in detail ( color, shape, size ). First repeat the request without change, then give your answer.
