Brittany and I were twins, though I was twenty minutes older than her, and we teased each other by calling me ‘big brother’ and her ‘little sister’. I don’t know if it was because we’d shared space inside Mom for just under nine months or not, but we were always close. We had shared interests and loved outdoor activities. Both of us were active in school sports, even on the same teams for winter and spring, though different events. Soccer, downhill skiing and throwing shot put/discus were her sports. I did cross-country running, Nordic skiing and ran sprints/hurdles.
Mom had been a nurse when the parents married, but with Dad having a decent position as a production engineer, she went back to school. She studied to be a doctor when it was almost unheard of for women to be physicians. Dad supported her throughout, even helping to take care of us after we were born. Even with Dad’s job, money was tight and we lived in a cramped two-bedroom apartment, Brit and I sharing a bed during those years.
She finally finished her residency when we were five and we soon upgraded to a more spacious three-bedroom place. Though my sister and I now had our own rooms, we still frequently ended up in the same bed ... it had become our normal. Three years after that, Mom was recruited by a hospital in the northern part of the state. Dad was able to find a production engineer job up there, so didn’t have to change careers. So when Brit and I were eight, we made the big move. The change from a large metro area to a town of eleven thousand was a bit rough, but we managed.
At first we rented, but after a year of weekly searching, Dad lucked into a foreclosed farm. So we went from renting a small three-bedroom house to a four-bedroom farmhouse in good shape on four acres of land that included a one-acre pond. The only bad part was it was a ways out from the main town and neighbors were few. So Brit and I continued to be each other’s best friend and did everything together. All four of us were close, hugs and chaste kisses were common in our household, though Dad and I settled for just hugs. Ya, we were ‘touchy-feely’ in ways, but we hadn’t even seen each other fully naked since the parents told us, ‘No more skinny dipping in the pond’ when we were twelve.
Being so close, there wasn’t much we didn’t know about each other. We even told each other about The Talk we’d each gotten, her from Mom and me from Dad when we turned fourteen. It basically amounted to ‘Be safe and don’t do anything you’ll regret later’ for both of us. And they were ... supportive in their own way, knowing that Brit and I weren’t the types to pass on ‘opportunities’. Dad had given me a box of condoms and Brit got put on The Pill.
We didn’t share every detail with each other; but I knew when she had her first kiss, her first petting session, and when she lost her virginity. She also knew all my milestones.
Since we’d grown up so close and felt entirely comfortable with each other, what happened was probably inevitable. When both our social lives fell apart after high school graduation, we just seemed to gravitate towards each other. This is the story of our coming together, and it begins in June of 1978.
