I came to see the doctor for an examination. The doctor auscultates my heart with a stethoscope and tells me that my heartbeat is very slow and weak and hard to hear. He has a special device to make my heart beat louder and faster. This is a sex machine. The doctor inserts a dildo into my pussy and turns on the fucking machine. The doctor says that now my heartbeat can be heard much better. He also needs to listen to the heartbeat during my orgasm. The doctor gives me a second stethoscope and I also hear my heartbeat. The doctor takes the vibrator and puts it on my clitoris. I cum with a big squirt. The doctor and I both listen to my heartbeat.
