Sorry it took so long with this story. I do not write when my mind is on other things. I had graduation from college and starting a new job to worry about. Thank you for all the comments, I tried to implement some of the changes you requested into this story.
This is the second chapter of a series, please read the first chapter before reading this if you want the full story.
Jason found it hard to concentrate in the weeks following his first sexual encounter with his sister, he could not think about anything else besides what he had promised his sister in the kitchen. He had promised that she did not need to tell anyone else of their love, but now that his head was on straight, and his beautiful sister was not naked in his arms, he began to think clearly about some things. That promise seemed like such a good idea at the time, but he had relegated him and his sister to living in secret, living a lie for the rest of their lives. He did love his sister, but with that came a sense that he was ruining her life, being selfish.
His mind wandered over the next weeks trying to wrap his head around the idea of what he had done. He checked into changing schools to the University of Michigan, they said that it was a little late, but because of his excellent grades and SAT scores that they might be able to do something. He received word about a week after he called them that switching would be no problem should he choose to do so. That was what really started him thinking about the future, and the past.
When Jason and Andrea were just starting ninth grade, and Jason had just gotten out of his first serious relationship, he noticed that Andrea was there to help him through it (although in a different way than this time). Around that same time, Jason noticed that his sister was truly beautiful, but this he chocked up to teen hormones and overactive imagination. Back then, every girl with two legs and breasts was beautiful to him. Nothing happened that school year, but Jason and Andrea became much closer over that year and following summer. The next school year, however, he found Tracy. Tracy was pretty, if not beautiful, and had a super lean marathon runner's body, small tits, and a great smile. Jason fell head over heels in love with her. His parents liked Tracy, although Andrea remained reserved, but not hostile. About their Junior year, Jason had distanced from his sister noticeably, and drew even tighter to Tracy. Tracy held every moment of every day. This is about the time that Jason started to "help" Tracy with her homework. At first, it was only the classes that they were in together, she would say something about not understanding, and Jason would try to explain, but he found that it was easier to just do it himself. This continued all the way until the end of their senior year when Jason got into Stanford, and Tracy got rejected. Tracy did not learn a thing since sophomore year, so her SAT scores were lacking majorly, while Jason got one of the highest scores in the state for that year. Jason tried to console her, but she didn't want the truth staring at her in the face all the time, so she broke it off with him.
That trip down memory lane got Jason thinking about him and his sister going to different schools in the fall. Sure, he could switch schools, but that would essentially guarantee the life of secrecy and lies. He could stay where he was, attend Stanford in the fall, and his sister would fall for some guy at college. His sister could live in the open, and they could chock this up to teenage hormones and depression over a breakup. He walked around the house in a stupor most of the time while thinking. Everyone noticed his mood, his parents thought that it was because of his breakup, but his sister knew the truth.
------------------------------------------------------------------------------------------------------------------------------------------
Andrea noticed her brother walking around like a zombie most days, at first she thought it was about his breakup, but after trying to take his mind off it with a blowjob in the hall way, he just stepped around her and kept on his way. She was getting worried about him, she was worried that he was regretting the promises that he made in the kitchen, she was worried that he was having second thoughts about their life together. Andrea tried to stay upbeat for her brother to show that she didn't have the same concerns. She knew that a face to face conversation was the only way that this was going to get resolved, but Jason would blow that off too.
------------------------------------------------------------------------------------------------------------------------------------------
"Jason, we need to talk." Andrea stated seriously
"I know." Jason said simply
"Well, when do you want to talk?"
"Soon, I need some more time first."
"Okay, but don't take too long."
That was the longest conversation they've had a few times over the few weeks since the kitchen.
more weeks went by before Andrea assaulted her brother in the dining room after breakfast.
"Okay, that is long enough! No more thinking, no more sulking! I'm at my wits end here!!!" Andrea yelled.
"I'm sorry, there's just a lot to process right now."
"Like what! Talk to me Jason! What are you thinking about?"
"I'm just trying to make everyone happy with the least amount of heartache and damage."
"What do you mean 'Make everyone happy'? You said that the only people that mattered were us! You promised that no one else had to know!" Andrea was on the verge of tears by this point.
"I know I did, but I was captivated by a naked angel in my arms." He actually managed a weak smile at this point.
"So, you only said those things because you wanted to fuck me? Is that all I am to you Jason? A fuck toy!!"
"Damn it!! NO! of course not, I love you, that is precisely the reason that I can't give you what you want and not hurt you in the process!"
"What do you mean! You being with me is all I want, how does that hurt me?"
"If I were to keep my promise that I made you, we could not tell anyone else, we would have to live in secret, live a life full of lies! What would we tell Mom and Dad? What would you tell all of your college friends?"
Andrea could see his logic, but she did not want to, she loved her brother, she wanted her brother more than anything.
"So what, did you just want to forget that what we did ever happened? Did you want me to deny the fact that I have loved you ever since we turned 15? I'm sorry Jason, but I cannot!"
That line caused Jason another flashback to ninth grade. Andrea was around Jason a lot that year, she would be there at all his failings at sports, she was there to cheer him on or cheer him up about everything he did or failed at (mostly anything physical). Although Jason didn't notice at the time, Jason and Andrea would walk in on each other in the bathroom or changing in their rooms more that year than in the previous fifteen put together. Andrea was always in his head, but not in a sexual way. She was the voice in his head to keep going, to never stop. She was his own personal cheerleader, until he met Tracy. He snapped back to the present.
"I know you think that now, but once you get to college, you will be bombarded by guys, and it will be better for you than I would be."
