The next summer I was 18 and had just finished high school when it was time for my annual skin exam. My acne had cleared up, but the doctor had recommended coming in once a year. My mom had made an appointment adjacent to mine, so she drove us both to the doctor's office.
We arrived close to our appointment time. Before there was time to fill out the intake forms, an assistant called us both back. I think she'd assumed that I was younger, because she seemed a bit confused, but led us both to an exam room. She took the intake form from me and said she could fill it out. The assistant verified the my information was still the same, if I was taking any mediation, and if I had any particular concerns.
She made some small talk and asked me about summer and college plans. The she said she thought it was so nice that I still let my mom come back with me and mentioned that her son was in the stage where he's embarrassed about being seen anywhere with her.
When she'd finished the paperwork she something like, "It looks like you've done this before, so I'm assuming you know the drill. Everything off, including your underwear, and the doctor will be in to see you soon." She left, closing the door behind her.
My mom had finished her form and set it on the counter. She apologized saying she didn't realize that they'd take us back together, and offered to wait outside. I told her she could stay.
I began undressing until I was down to my underwear. For a moment, I considered leaving them on. But, the excitement of the situation took over and I took off by briefs. I was standing in front of my mom, naked as the day I was born. "You've grown a bit since I last saw you," she said to break the ice and we both laughed.
I sat down on the exam table and the doctor arrived. She proceeded to do the skin exam while my mom watched. When she was done, the doctor suggested doing a regular self exam and advised getting some help for the tricky to see bits. She said that since I was comfortable getting undressed in front of my mom, that my mom might be able to give me a hand. I was surprised at the suggestion that I get naked in front of my mom on a more regular basis, but neither of the women reacted at all out of the ordinary.
The doctor said I could get dressed and wait outside while my mom got her skin exam. She left us alone in the room. I put my clothes back on. Meanwhile, my mom started to undress. I'd got all my clothes back on, and was taking my time getting my shoes tied. She'd stopped at her underwear. It was obvious I was stalling and she joked, "Are you trying to see me naked?" I felt my face flush and quickly finished tying my shoes.
As I stood up she said, "I guess it's only fair. I did get to see you." She took off her bra and then her panties and stood before me naked. I was stunned. My mom said she'd meet me outside. I broke my stare and went out into the lobby leaving her alone. She came out to meet me after her exam.
The doctor had given her some paperwork on self exams. When we got home, my mom said that it was a good idea to have someone help me check my skin periodically and said we could do it together. I was planning to commute to college from home, so it would be possible.
