Alex always tried to be popular but it just didn't happen no matter how hard she tried. Now as for me, her older brother Joe, it just happened. I didn't even try and she was still mostly known as Joe's little sister at school. So when Alex started dating Frank she thought she was finally making progress. Frank was one of the most popular boys at school but had a reputation as a player who has never been with a girl long.
I knew how big a jerk Frank was to girls and tried to tell Alex but she refused to listen. So the day after Frank asked Alex out I warned him about mistreating my little sister. Frank also chose not to listen to so after two weeks of dating Alex and not getting her in bed Frank asked Beth out who he knew would sleep with him. The problem came when Beth excitedly told her best friend about Frank asking her out because her best friend was Alex and Alex hadn't told Beth she was dating Frank already.
So that afternoon I arrived home from school and found Alex crying in her room because of Frank cheating on her. I told her that I would take care of it not to worry that no one could hurt her without consequences. The next day at school I attacked Frank in the locker room. After whipping his ass told him that he had better stay away from me and my family or next time it would be worse. I got caught by our gym teacher and was suspended for 3 days for fighting at school. So I got grounded when I got home cause I refused to tell why I had attacked Frank.
When Alex got home that evening and found out how much trouble I had gotten in for her she thanked me and apologized for my getting grounded. She didn't understand why I was taking the punishment because we never really got along with one another. I explained that she was my little sister and that while we might disagree a lot no one was allowed to be mean to her. She started to cry and said to me.
"Thanks for looking out for me big brother, but I probably deserve to be cheated on. I mean, I couldn't make Frank happy because I wouldn't do anything with him. You know, like... Things guys like girls to do. I've never done any of that before and I was so scared to mess up."
I nodded, a little surprised that she was talking to me about sexual stuff, but I realized it must be tough for a girl if she hadn't had any experience. I was thinking about how scary it might be for her.
"Honestly, I was just going to ignore his cheating on me and sleep with him anyway just to get it over with. Maybe if I do what Frank wants me to then he wouldn't cheat on me and we can continue dating."
She took a step back from me when she saw how angry I had become from her words. Then once I had calmed down enough to speak without yelling at her I told her.
"If you think for one second about taking that piece of garbage Frank back I will kick both of your asses. I know that you can do a whole lot better than some jerk like Frank. You shouldn't have sex until she was ready and then only with someone who will actually care about you not just about getting between your legs.".
"You don't understand I'm not popular or pretty so how do I do better than Frank. No one else even knows who I am except for being your little sister." She told me with tear-filled eyes as she cried.
"Alex you don't know what you are talking about you are a beautiful and attractive young woman. In fact, if you weren't my sister I would have already made a move on you myself. I also know a lot of the guys at school think you are attractive."
With a look of disbelief after a brief laugh, she replies by saying to me.
"You are only telling me that to cheer me up."
"That isn't true I am telling you the truth whether you want to believe me or not."
"You have to say that; you're my brother. Doesn't mean that you actually think that about me."
"Since when have I ever done something just because I am your brother? How can I convince you that I meant what I have said?"
"Nothing that you can say or do will convince me that you meant any of those things!"
"If you are so certain that I can't prove that what I just said is true then let's make a deal; you give me one day to come up with a way to convince you that I meant everything that I said to you today. If I fail then I won't say anything about you dating Frank but if I do, then you can't go out with him again no matter what happens."
"Ok one day, but when you don't figure out a way then I also want you to admit that you were lying to me," she said with a sad little pout.
I spent the entire time from Alex leaving my room until the following day thinking about what it would take to convince her completely. It kept coming to the same thing no matter how I looked at it or thought it out. It had taken me the whole day to come to terms with the facts and make myself willing to follow through with the plan I had come up with. 'Cause let's be honest the only way I had available at the time meant I would have to personally have sex with my little sister Alex.
