how I was manipulated in Digha

This is shalini. I am an 18 year old girl who lives in Kolkata. I have recently been promoted to class XII of my school. I have got a fabulous figure of 36 24 26 and have got great breasts. They are quite large and perky. I have got a pretty round ass and a full figure. I have always been very beautiful and fair, probably inherited from my mother who was a bharatnatyam dancer. Hence I have got a toned body. My most impressive feature is my ass which gets really highlighted when I wear Jeans. Even Amerian size jeans are a perfect fit for me as they accommodate larger ass sizes.
When I go out even my Elder brothers friends pass lewd comments. Offcourse I have never complained as I am eager to flirt. I have never had any physical relationships with any boy or man but have fantasized. I tend to wear short skirts and tops as it is hot in Kolkata. In my house I never wear bra and sometimes even go pantyless. The boy who works at our house had once seen me without my Panty while I was cleaning the kitchen and bending over. My pussy hair was slightly exposed at that time but I recovered quickly. Now I was 16 at that time. Since that day the boy and his road side friends (he lives in a nearby slum) have sometimes followed me from school in the hope of a second flash. So I have put myself in some embarrassing situations.
This incident occurred while I had my school summer vacations. My Mom had gone to her native place in Gurgaon along with my brother and me and my father were staying alone. One day my father and his friends had come to our house to play cards and they had a bet. The bet was whoever loses would sponsor a trip to Digha which is a nearby beach, hardly a days travel. Unfortunately my father lost the play and his buddies, Ramesh, Shyam, Sundar, Bappa, Pintu and Anirban started to press the bet. My father was looking helpless as he could not possibly leave me any where and go out for 3-4 days. In order to ease his agony I said that I can also come along. Immediately my father took me aside and said that I might be uncomfortable with so many men and no girl or women in the group. I asked that maybe their wives whom I knew well could come too. But my father corrected me saying that this will be sponsored by him hence it would be wiser if the group is small. I thought about it and wondered that it might be even better as being the only child I would be pampered by my father and uncles as we had a very good rapport. I said that it would not be a worry.
So we decided to travel the same weekend. Now this was the first time I was going to a beach so I wanted to enjoy myself thoroughly. The trip was for 3 days and so I packed in a couple of jeans and some tops. I had heard that Digha was hot and humid so I put in my lightest of clothes. A couple of shirts and skirts. Since I had no new under garments I decided to try my mothers cupboard. There I found a couple of nighties which I thought would be OK for me. Since I used to sleep in my brothers old t shirts I never had any night wear. It was not a problem as everybody had a separate room. There was only one problem with the nightie. They were backless and the straps and neck were quite deep. When I tried those on the nightie was not even till my upper thigh. It was just covering my large butt and the cleavage was more hanging out than tucked in. Even if I bent a little forward my ass would be exposed .I thought to myself that I have to wear those only during the nights so I took those. Next I shaved of my hair as I did not want to give anybody a fright. I was all set.
On Friday when we boarded the train we were a happy bunch. We reached Digha on Friday afternoon and started to search around for a hotel. Eventually we found one with a couple of empty rooms. Now my father and his 6 friends started consulting among themselves and decided to take the rooms and share them at the same charge. Now my jaw dropped. I started protesting that It will be better ig I had a separate room. After a lot of bickering my father begged me to relent and said that me and him will stay in one room and the rest can share another. I was Ok with that so we just checked in.
We decided to freshen up I decided to make first use of our bathroom. I took out a skirt and top and went in As it was hot I did not take a bra and panty as we had decided to rest a bit. I freshened up and put on the clothes (I avoided coming out in a towel which I generally do) and as I came out I saw Ramesh, Shyam and Sundar sitting with my father and everybody wearing only their towels. As I came out my father explained that to freshen up quickly he had asked them to share this bathroom also. I just smiled and they smiled back. But I thought I saw them checking me out from head to tow. Their eyes were roaming around my exposed white and smooth thighs which had been been covered only by a mini skirt and my large boobs and nipples were poking out freely from the flimsy shirt. As I came in front of the mirror I saw that as my body was wet my nipples were also exposing my pinkish hue through the shirt which was clinging to the wet boobs.
