Her Heart

*Flash Back Cont.*

You put on the stethoscope and placed then end on Lucy's chest. There was silence for a minute..."I don't hear anything..."

Lucy tilted her head to one side. "Maybe it's my shirt?"

"Maybe...can you lift it up?" You ask.

She nodded, and did so.

Now, Lucy had some fur instead of skin which covered her back, breasts, and pussy. You knew this because when Lucy often took a bath with you. Just like any sibling would. So you weren't surprised.

Once Lucy had lifted up her shirt, you put the end of the Stethoscope on her chest again. You then hear her heart, which was beating fast since she had been working out. "Wow..." You say. "I can hear it so clearly..."

"How does it sound?" Lucy asked.

"Loud...but pretty."

She blushed, and you move it to another spot on her chest. After a few minutes of that, you move on to her lungs.

The sound was like wind blowing through the screen door.

"Your lungs sound nice too." You tell Lucy.

"Great."

You start to take off the stethoscope when you remember something. "The doctors also use this to listen to the patient's stomach."

"Why?"

"To see if there's air."

Lucy blinked, but allowed you to listen anyway. You hear little bubbling, and some growling...seemed your sister was getting hungry...
