From age 6-10 I avidly played doctor with a childhood friend of the family every chance we got, and it was often. Our mothers would sit in the kitchen for hours chatting over tea while the kid's had their 'play date' in the basement toy room.
She was the instigator of our playing doctor, but I went along ever so willingly. We would set up our makeshift exam room in the laundry closet, behind the furnace. The role play setting was medical, but it was a thinly veiled excuse for us to explore each other's most intimate places. She always had great ideas on using found items in creative ways. we both enjoyed having our anuses inspected, probed, and items inserted. She liked the same done to her vagina. She was always delighted with my erection, so after the first 'exam' I wasn't embarrassed.
I recall her giving some specific instructions on how I should 'examine' her vulva. Sometimes she would throw her head back and quietly voice her pleasure, encouraging me to continue my exploration.
Her brothers and the neighbor girl joined in from time to time, but most often it was just the two of us. Sometimes one or more of the others would maintain a 'lookout' to send up a warning signal at the sign of approaching adults. Many times we would forgo a lookout setting a daring tone of excitement over potential discovery.
Sleepovers were great. We could play in the bedroom in the wee hours of the morning. Her older brother thought up great fantasy scenarios about our being space traveling aliens. Our genitals would always be integral to the missions somehow or other. We would need to rub them on each other's navels as a means for revival or energy transfer. We would grasp each other's privates to be able to 'teleport' to the same place together.
As we got older and our circles of friends grew our play dates became less frequent. At some point we would see each other at only more formal gatherings of family and friends. At some point during that transition she was my first kiss. We would see each other from time to time throughout our high school days. I dreamed about trying to rekindle some of that same childhood fun we used to have, but by then it always seemed her attention was elsewhere.
