How i became a sissy/my first blowjob

I'm a 17 year old sissy now but i started crossdressing 4 years ago when i was 13 :).This is the story. One day my parents went to our lake house for the weekend with my s****r but i was feeling sick so they left me with my grandparents. They were taking care of me for a day or two and i got better so they left and i was home alone.I had 5 more days until my parents were back.One day i was feeling very bored so i opened my s****rs closet and looked at her stuff. I noticed thongs,i never knew she wore them (she was 17 back then). I wondered how they would feel so i put them on. I never felt sexier in my life,it felt like i was born to wear them .I started looking at other stuff and i saw lots of bra's,so i put one of them on.From that moment i knew that i was going to be a crossdresser for the rest of my life. I've put some of her shorts on and her t-shirt and i looked like a real whore. I went to the bathroom and put some of her makeup on. I looked realy hot (i already had long hair and i regulary shaved). I then wanted to watch some porn.I offcourse turned on shemale porn and then i realized that i didnt want to be the man fucking the girl but i wanted to be the girl.I wanted coock now! I didnt know how to get one so i had an crazy idea,i called my best friend over to play some ''games''. When he got to my place he was very surprised,first he didn't reconise me,but when i explained everything to him i saw that his dick was hard.He just looked at me and said :''Suck it''.When i heared those words i was a little frightened at the begining but when he unzipped his pants and pulled his 18cm cock out ,my mouth started to water.He put his cock inches from my face and told me again''Suck it''! I slowly started to jerk him off,and i heared him moaning. And then, for the first time, i put a coock in my mouth. I could taste the precum and i loved it.I was first licking the tip and i cupped his balls.Then i started sucking his balls too,after that i tried to deepthroat him but i choaked at the half.
