The story of me becoming a slut

It all started when I was 15 years old I just started to grow into a lady and I was extremely inexperienced in sex. I was only 15 and already had 34 c’s which was shocking for me because I had been a gymnast my entire life and any gymnast I knew had really small boobs, but my big boobs was the reason I had to quit because they became to big to work with. My mom is white but my dad is Hawaiian which gives me and my brother and pretty dark tan all year round. Being developed so fast and so young I would get hit on anywhere I went. But I always ignored the idiots who would try the dumbest lines I have ever heard of. My first sexual experience was with my uncle nick. Well he wasn’t my actual uncle he was my grandma’s younger brother. So he at that time about 45. Even though he was over all the time to help my mom and grandma watch me and brother while they worked, I never found him attractive. He was tall, lanky, hairy, very redneck looking and had a big gut. Now when I was 15 I just started high school and all my friends started smoking shortly after they did I did also. I never knew where to get the cigarettes from because I didn’t know many older people who were willing to buy me any. I also couldn’t steal them from any adults I knew because they were all very stingy and always knew when one was gone. Well one day I was going through my moms drawers to steal me a cigarette and my uncle caught me. He asked “What do you think your doing?”
“Please, please don’t tell my mom she’ll kill me if she found out.” I begged.
“Well honey, I won’t tell your mom but she has been noticing her cigarettes running out a lot sooner .So why don’t you just put that back.” He replied.
“Okay, sorry again, and thank you for not telling on me. It’s just all my friends smoke and I feel left out.” I said in a pouting voice.
“Alright well I’ll buy you cigarettes I come down here but don’t tell your mom where you get them and try not to get caught, okay?”
“OOO thank you, thank you, you’re the best uncle ever.” I replied and gave him a big hug. A few months passed by and Uncle Nick brought me cigarettes every time he came to visit or help out. Then one weekend he offered me to come spend the weekend at his house. I said yes because he had been so cool the last few months. Well after we got back to his house it was late and we had eaten on the way there. So when we got to his house I was super tired. So I took my bags inside and got set up for bed, Uncle Nick helped me set everything up. He helped me unpack my things into the empty drawers in the guest bed. While we were unpacking my bag he lift out a pair of my work out shorts that I wear to bed in the summer, they were really short, shorts that barely covered the bottom of my ass and now that I had grown I little more they show my bottom ass cleavage. When he grabbed them he said “WOWO look at these can you even fit in these?”
“Yeah I can, there old though so there a lot shorter than there supposed to be” I replied.
“Well you are just going to have to try these on for me sometime” he said. I didn’t reply, I often didn’t reply to comments like that because what do you say to that? He had just started saying these weird and awkward comments for about a month now, but I never knew if he was just joking or was serious. After I had finished unpacking I got dressed into my pajamas but not those shorts because of the awkward comment earlier. When I walked into the living room where he was watching TV I had noticed that I didn’t put on a very appropriate shirt it was a whit tank top that gave me major cleavage. But I didn’t know what to do because I had already sat down on the couch.
