I will try to make this a short story. Melissa, Missy, was born 2 days after me. So we always celebrated our birthdays together. Her mom was my mom's younger sister. They were always close so when Missy's parents died, my mom took it hard.
Missy's parents had left a will. And in it they asked my mom and dad to take care of their daughter. It helped ease the pain of loss for my mom. She loved taking care of Missy. So that is how Missy came to live with us.
The accident and Missy comming to live with us happened when we were 2. So we grew up as brother and sister, not cousins. As the years went by, things began to change between us. She became shy and I became protective. Every time someone hurt her I would find them and beat them black and blue. She would get mad at me for this saying that no one dared to date her for fear of me.
When we turned 18 our parents gave us the usual birthday party. One day after my birthday and one day before her's. I was watching out for her as usual when I saw her leaving the party with a jerk named Tommy. I knew what he wanted because I had over heard the locker room talk. I was not about to let that ass-hole touch her.
I had no sooner gotten to where he had taken her when I saw her struggling with him. I heard him say,"Come on Missy. I know you want it."
"Get off me. I did not come with you for this."
"Aw, Missy. Yes you did. If you didn't why did you come?"
It was then I grabbed him from behind, hit him a few times and threw him out the front door. I turned around and saw Missy crying. "I am sorry Missy. I did not want him to hurt you."
"It's not that, look."
I looked and saw that her new dress had been torn. I felt sorry for her and helped her to her bedroom. Then as she fell asleep, I went down stairs and told my parents that Missy had gotten sick and was in bed asleep. They stopped the party and sent everyone home.
After everyone had gone, mom asked me if she and dad should change their plans for the weekend. I told her no and that I would look after Missy. "That is just like you. Her guardian to the last." Mom smiled at me and told me not to stay up to late as I had to take care of Missy in the morning.
The next morning I had to reassure mom and dad that I would look after Missy. "Are you sure you can handle her being sick and all?"
"Yes, mom, I will take care of her. If she gets worse, I will call you and you can come running back."
"Don't patronize me, Mark."
"Mom, I will take care of her just like I always have."
"Yes, you alwasy did watch out for her didn't you."
"Don't worry, mom. I will call if anything happens."
"I know, dear. I know."
They left for the airport and I went up to Missy's room. Missy was still asleep, or so I thought. I softly knocked on her door. "Missy? You awake?"
"Yes I am. You can come in Mark."
"Mom and dad just left and I am checking on you to see if you are ok."
It was then I noticed what she was wearing. It was an old tee-shirt of mine. It was so thin that I could see right through it. Her nipples were hard and poking through the material. I saw that they were dark brown in color. I looked lower and saw she had no panties on. I averted my eyes and tried to hide the hard-on I was getting. "Hey, Missy. What do you say to us going to the mall and replacing your dress?"
"I would like that, but, I would like to get more than a dress."
"I'll tell you what. I will get you anything you want, seeing as how I didn't get you a birthday present. What do you say?"
"Great! I'll get dressed and then we can go. Ok?"
"Ok." I left her room and my desire for her. Or I tried to at least.
On the way to the mall, Missy asked me to make her 18th birthday perfect. I asked her how I could do that. "By doing me a favor."
"Yeah, what?"
"Going into the changing rooms with me."
"What?"
"I hate trying on clothes and then comming out to see what somebody thinks. What if somebody laughs at how I look? What if they point their fingers and say things like "Oh my god, you are so ugly. Why did you try that on? You know it makes you look uglier than you already do." I just can't take it."
"Come on, Missy. You don't look ugly. You never have. How could anyone think that?"
"I don't know, Mark. I just don't like having to come out of the changing rooms. Ask mom she'll tell you."
"All right but I don't have to watch you change." What was I getting myself into?
We went to a department store first. There she tried on a few dresses untill she found one she liked and I liked too. Then we went to the bathing suit department. "I need a new one. My old one doesn't fit any more." I thought ok because she always wore a one piece. Little did I know that she had a change in mind.
"Now, Missy, I know I said I would go with you into the changing rooms but that was before I knew you wanted a new bathing suit."
