First Medical Instrument you Bought?

A stethoscope. I already owned a great looking medical weighing scale before I started playing

Pretty sure it was a box of catheter from the local medical supply shop, and a speculum later.

My first medical instruments that purchased were a glass rectal thermometer, an 8 oz red bulb and a two-quart open mouth enema. I was 20 and I was so nervous. When I went to the counter the older woman who waited on me asked it I needed anything and then suggested I might want to get vaseline and some soap which I said yes mam and she said this will save you another trip to store. I am sure I blushing beat red. This was at a Rexall Drug store in Bayonne NJ. I wondered it she figured out these were going to be used me. Later that day, I was meeting an older woman later that day who was going to use the equipment and also spank me. She was a surrogate mom to this boy for several years.

@SoMDBadBoi At least she did not have you buy a wooden hairbrush as well!

My first was stethoscope, a Littman lightweight with black tubing (before they changed the style of the diaphragm). It had seen a lot of use through the years.

A metal-glass 5cc syringe and some needles at late 80's

At the time I didn't know the word 'medfet' or consider myself taking a plunge. I just wanted to play doctor with my bff. We got a thermometer.

An enema bag, if that counts. Most of the fun medical items require a play partner and I’ve yet to be in that situation.

I bought a plastic Anno scope.
