SISTER'S BIRTHDAY PRESENT...

I never think about crossdressing in my life but unfortunately it was forced to me. It started with a game and reach higher from my thought. I am Santosh and I have one bigger sister only in my family. she was 22 years old and I was 18. My mom and dad was no more so she take care of me.
So we are getting the story, it was summer vacation and me and my sister are free. My sister birthday have to come and  My sister and her friends arrange a short party at our home for the whole day. I was not interested in the girls party but because it was at my home so I was included in it no matter I want it or not. My sister said me to help her but I argue her that I was not interested in her girls party and what would I do in her party. She smiled and said if I was a girl then she sure that I would be have a lot of fun. I did not know how to react on these words. My argue was over with shyness on my face. She said that she did not know that her Bro shy a lot. She added that she was sure I was looking more beautiful than her brother instead of sister. I told her to close this discussion now. But seeing my shyness she continue teased me. She told me that I was looking cute and pretty in skirt or saree. I could not hold this but she throw a blunder and said that she wanted me as her sister on her birthday as present.
Between this argument the door bell rang and her eight friends came into the house. I told my sister to stop this teasing right now. She smiled and said that she deserve a sister on her birthday. I beg her to stop this but she said that it was on my luck. Then she announced to her friends having some snacks. I move to garden in backyard of the house and doing some basketball practice. After half an hour all girls came into the garden and asked me about my sister birthday present.I told them that she told them about that. Then they said that she told them to help her for her birthday present. I scolded them that it did not right and it would not be happen. They said that if my sister allow them then they made me her sister by force because they were eight and I was alone. But she want to give you a chance. I was surrounded by girls and I did not have any choice So I listen them.
They said that I was looking good in basket ball so the deal is that we girls and you played a match 15 minute duration. If I win then I did not dressed as a girl but if they won then I had to dress as a girl. I told them that I was agree on that but one verses eight was not fare.  They discussed it with my sister. Then they said that they allow me one vs four girls. I feel some relax but my sister said that she agreed on this but if I loose then I would have to be her sister for a week. I told that this was not fare again this bet is for today only. But she said that she had a solution  that I had to play another basketball game after dressing up as a girl. And then I played with only two girls and if I won then she dressed me in saree for today and if I loose then it would be a fun for a week. Also I do the all works she told me. So I have only a choice to say yes because I knew that I easily beat two girls.
So the first duration of 15 minutes started and one vs four had no match and they were good in basket ball. But I was also good but at last I loose only from one basket. And all girls were very happy and I was kicking the ground with frustration. 

Now the girls took me inside and told me to undress they gave me a bra and panty to wear. I was stuck in ackward situation. I requested not do do this. This is very itchy. But my sister told me that I earn this so I had to do it. Seeing no choice I slowly grabbed that bra and panty and changed panty. I feel shivering in my body during wore panty. I tried to wear bra but failed. My sister smiled and said I was her best present ever and helped me to wear bra. Then she gave me a pink top and white skirt to wear. The top having full sleeve and it reach only the below of my chest and the skirt was too short just above from my knees. After wearing them they said that they gave me shoes to wear now but after this they wanted that I wore high heels. The shoes also had one inch heel and I felt strange after worn them. I told them to play again because I was in hurry. But my sister said to be calm because it is predecided on bet that she dressed me in saree today. I was in anger from inside but what could I do. Then she said that she only dressed me half. I asked her what was her mean. Then she said that playing as a girl means everything. Then she took two tennis ball and fill the bra cups with them.I complain it but she said that I had to be like a girl in the next game. Then she added a wig over my head and put a little make up on my face as

cream,powder,lipstick etc. She did my nail painting too. After that she did my earrings and some bangles in my both hands also. I saw my reflection in the mirror and I had no sign of boy in the mirror. She tease me again that I look more beatiful after wearing saree. So I am ready to play but feeling stucky in that situation...
