First time sex

I was not completely honest in my first post
1 I was in my early teens
2 it did happen in garage behind our house
3 I was wearing my older sisters things
But it was not an older neighbor that caught me , it was my mom's oldest brother my uncle Tony.
With in minutes of catching me dressed in sister's bra and panties Uncle Tony gave me two options. Option one he tells my parents. Option two I suck his cock and everything kept secret.
I chose the latter and within seconds he had his big thick uncut erection out of his slacks and was growling at me to get down and suck it.
My only experience was from the pictures I had seen in my limited collection of porn, but that was enough to give me basics of what I needed to do. I quickly went to my knees and took the big swollen head in my mouth and began sucking. Right from start I knew I liked it, the taste the texture even the musty smell of my uncles crotch was exciting me. By now uncle Tony grunting a string of obscenities above me. "suck it bitch, eat that cock you little slut ". Hearing him talking to me like that made me suck harder. Uncle Tony had both big hands on sides of my head and was now thrusting his big fucker deep into my mouth. I felt him swell and my mouth flooded with thick creamy cum.
He pulled out of my mouth and zipped up. "that was great mikey remember boy it's our secret "
And with a wink and promise to "see me again real soon " he was gone leaving me on my knees on the dirty garage floor his semen dripping from my chin.
