First Time Sucking

When I was 16 I was curious about men and what it would be like to have a cock in my mouth
I began going on chat rooms and talking to guy's about it
Eventually found a guy local to me that was 47 we spoke for a few minutes about what we would want to do and he asked if I'd like to come over and give it a go
Which I said yes to and got on the bus and met him at the bus stop and followed him home
We went straight to the bed room where he dropped his pants and pushed my head down till I was eye level with his already hard cock about 7"
He said open up then and pushed it straight to the back of my throat making me gag but I liked it I sucked him for a while be for he put me on the bed doggy style and lubed me up and pushed it in
I hurt for a good 5 mins
But I got comfortable with it and I felt amazing before he filled me with his cum and set me on my way still leaking
