There is violence in this story and some of it is sexual. The story has incest elements, non-consent, and a happy ending. I'm putting the story in non-consent.
*
My sister is three years younger than me. All through school she was quiet. Lots of people didn't know she was my sister, even though she went just about everywhere I went. I played baseball and she became the official scorekeeper. I went to football games, basketball games and she went too. But as soon as we arrived she turned invisible. I made it a point to check on her often and I'd find her off by herself, reading a book or keeping score.
As happened I graduated and she had three more years of high school. I attended a local college and she started keeping score there, too. She also started maturing physically. Puberty arrived late and slowly. Since in our family everyone shared chores I saw her bras in the laundry and saw her go from a 34A as a freshman to a 36C as a senior. She also grew taller. As a senior she was five-seven. She dressed to be invisible.
She graduated without having a single date in high school. Mom and Dad seemed oblivious to her lack of social life. When I tried to set her up with a couple of my college buddies, she went out with them, once each. She reported, "No sparks" when I asked her about the dates. I understood. I dated in high school and college but after a couple dates my report was, "No sparks" too.
I graduated and got a job about an hour away from home. Sandy kept going to school and kept getting good grades. She kept keeping score for baseball and basketball. I came back for important games and after the games we would go out for dinner together.
When Sandy was a senior a young man on the baseball team saw us at dinner after a game and the next time she went to practice he asked her about me. He asked, "How long have you and that older guy been an item?"
Sandy asked, "What older guy?"
"The one I saw you with after the game on Friday. You had dinner at Outback."
Sandy thought about how to answer and then said, "We've been an item since I was fourteen. We can't tell my parents yet, so I'd appreciate it if you kept quiet. Ok?"
"If anyone asks I'll say he's a relative."
"Yeah! That's good. Thanks."
When she told me about it I wondered why she had handled it the way she did. Then I concluded she didn't want to be hit on and I was a good way to avoid the unwanted attention. I let it go.
When graduation day came for Sandy Mom and Dad got dressed up and we went together. Sandy was as excited as I'd seen her since I hit two homers in one game. She looked good in cap and gown but even better when the robe came off. She dressed conservatively but I noticed she had matured and become beautiful in my eyes.
The next day she was back in sweatshirt and jeans.
A week later her life and mine changed again. Mom and Dad had driven to Costco to stock up for a family camping trip and on their way home a semi broadsided their car. The car was totaled and Mom died before they got her to the hospital. Dad was gone before we got to the hospital.
In the two weeks after Mom and Dad passed I came home a lot. Sandy had a job in town and wanted to stay in the family home. It was paid for and Mom and Dad's insurance set her up well enough that she could live in the house forever if she wanted to.
A month after the funeral I called her to invite her camping with my friends and me. She agreed instantly. We packed up and went camping. On our way she asked what I had told my friends about her. I said I had said I might be bringing someone, nothing else. She asked that I not say she was my sister. I asked why.
"They'll treat me differently and I want to just be one of the group, not someone's sister. Ok?" I agreed. My friends welcomed her and within minutes she had become part of the group. She showed she knew how to camp. Dad taught both of us how to camp cook, build a fire, pitch a tent and anything else to do with camping. Sandy helped get the tents up and the fire for dinner made and doing well. She impressed two of the men when they watched her build a fire and use only one match.
I smiled. She sat by me as we all ate dinner. Sally Brown asked, "Sandy, how did you meet Ben?"
I wondered how she'd handle the question. She smiled and said, "I kept score for the baseball team. Ben played first base. Near the end of the season we started going out after every game and having dinner."
I said, "It's unusual to find a woman who likes baseball enough to keep score and do it well."
Sally's husband, James asked, "What did Ben bat that season?"
Sandy said, "Three eighteen. Six homers, six triples, eighty-two RBI's and three stolen bases."
Sally's husband said, "Keep her. She's good!"
Sally asked, "What's a triple?"
Sandy explained and drew a baseball diamond in the dirt to show Sally what she was talking about. It led to a long discussion about sports. By late that evening Sandy was in. The men all liked her and the women liked her too.
We crawled into the tent that used to be used by Mom and Dad on our family campouts. We had one small flashlight on. Sandy said, "Thanks for not blowing my cover. I think I did Ok. They seem to like me."
"There are at least three men who envy me. They wish their women loved sports as much as you do."
"Remind me sometime to tell you a story about that." She unlaced her boots and took them off. She got her socks off and hung them from a string Dad had sewn in the tent so socks would dry over night. I hung mine next to hers. She peeled out of her hiking shorts and slipped into her sleeping bag. I saw a glimpse of light blue panties.
