My first time getting fucked wasn't my idea.
I was sucking and Jacking off cocks several days a week after school before my parents got home and the 18yo boy next door noticed this.
I was 13 and one day after school when I arrived home the boy next door, who was 18yo, was in his front yard and called me over.
He asked how I was doing and small talk like that and then he told me he had something to show me inside his house.
I sort of had the hots for this guy so I was happy he was talking to me and was interested in what he had to show me.
I never thought anything sexual was about to happen.
He took me inside and I asked him what it was he wanted me to see.
He took his cock out and said, this.
It was big and thick. All the cocks I've seen and sucked to this point were boys cocks, much smaller.
He told me to hold it.
I was a bit stunned and didn't say anything or do anything, so he grabbed my hand and put it on his cock
I didn't say anything but wrapped my hand around it as I was told and he moved my hand to make me pull his cock. he let go of my hand but I kept going still a bit stunned.
He took his jeans off and made me pull his cock more.
It was good big and hard.
He pushed lighltly on my shoulder and I went down on my knees.
He then said suck it.
I just stared at it and he said, open your mouth.
So I did and he slipped his cock into my mouth.
I could feel his big knob at the back of my throat.
He held my head and pushed his cock in as far as it would go.
I have a great gag reflex now, but not then so I choked and gagged a bit.
I just remember feeling his knob hitting the back of my throat over and over again.
Then he picked me up, grabbed my hand and took me into his bedroom.
I was still in my uniform which was a blouse and a short skirt.
He pulled my panties off and put me on the bed.
He pulled my skirt up, picked up my legs and spread them wide and started rubbing his knob on my clit and cunt crack.
Then when my cunt started to get wet, he pushed his cock in.
At first it fucken hurt.
He started pumping me.
Getting faster and deeper
After a few minutes, my little tight cunt was getting pounded.
It felt good and hurt at the same time.
He kept pumping and pumping until eventually he emptied his balls inside me and it went everywhere.
He told me, he knew I was sucking the boys off after school and if I ever told anyone what he just did, he'd tell my father.
For two years he threatened that if I didn't fuck him or blow his cock whenever he asked me, he'd tell my father. So for two years until I was 15, if he called me over to his place, I'd go in, get on my knees and suck his cock and if he said bedroom, I'd take my panties off, lay on his bed and pull my skirt up and he'd climb on me, lift my legs up and fuck me until he blew his cum into me and then I'd go home.
At 15 I realised that HE was the one that would be in big trouble if I told anyone what he was doing and never fucked him again.
Although it wasn't the best start to my love of fucking, it did get me started. 
I'd be lying if I didn't admit that I often enjoyed his fucking, but of course I also started fucking some of the boys I was only sucking off up to that point.
