I like the idea of a mad scientist/doctor using his stethoscope to examine a restrained female patient. The doctor unbuttons the patient's shirt, and places the cold stethoscope on her chest. She struggles throughout the examination. Example:
The mad scientist known as "Dr. Doom" entered his laboratory, followed by two of his guards. one was carrying the limp form of Miss. Fantastic. "put her on the examination table", said Doom. Fantastic slowly awakened and noticed that she was being brought to the table, which she could see was adorned with three sturdy-looking leather straps hanging from the sides, obviously meant to constrain the movement of the table's occupant.
Fantastic began to struggle, but it was of no use. the sedative had sapped all of her strength. the guard carrying her held her tightly.
"hold on for a minute", said doom. "i want to get a good look at my specimen." guard number one placed fantastic gingerly on her feet. at doom's orders, the guards had removed most of fantastic's clothing, so that she was wearing short shorts and a very tight tanktop. the cool air of the laboratory caused goose bumps to appear on her body, and her nipples stood at attention, clearly visible through her tank top.
"good, good, now please secure the patient to the table", said doom as he donned surgical gloves and placed a stethoscope around his neck. the guards wrestled fantastic to the table, and secured her arms, legs, and neck with the table's straps.
a bright light over the table was turned on, fully illuminating the struggling form of the beautiful captive.
"before we begin the procedure", doom said, "I need to examine you." he placed the earpieces of the stethoscope in his ears, took the metal end, and advanced towards fantastic, who continued to struggle against the straps.
"this might be a little cold", he said as he slipped the metallic disc under her tanktop, and placed it on her chest. he looked into her eyes as the thunderous sound of her quickening heartbeat flooded his ears. "hmmm", he said as he removed the stethoscope and reached for a pair of surgical scissors, which he then proceeded to use to cut away the heroine's tanktop. he continued to use the stethoscope on her naked chest.
