First blow job

It was the first time I had given a guy a blow job.. I didn't know what to do..

I had been out with this guy on a date enjoying myself. It was later on when we started kissing each other it was getting really passionate between us..
He was touching my tits up inside my top I was actually enjoying it
As we were kissing each other he's constantly putting his hand down between my legs putting his hand down inside my leggings and inside my pants.. I kept putting his hand away as I was having my period and I told him that.. He didn't seem to be pleased about it.
We are still kissing each other he's putting my hand down between his legs he's holding my hand down there rubbing my hand against himself in his jeans..
I could feel it getting hard as my hand was pressed hard against it with his hand holding mine down on it
He's undoing the buttons on his jeans and he's stopped kissing me as he was pulling his jeans and boxers down just below his knees..
He's sitting there with his dick fully erected in front of me.
As he was pushing my head down towards it
I'm getting nearer and nearer then I'm putting my mouth down around on it
I hadn't done it before I never knew what to do as I was just sitting there bent over down with my mouth down around on his dick
I don't know what happened but he was pushing my head up and down on it rather fast
It was going down my throat as he was pushing my head down
I was just letting him do it then he was holding me down as he was coming inside my mouth.
It was disgusting it was awful the taste of it was horrible.. It was lumpy it wasn't nice he's finished coming hes still holding my head down on it
I'm trying not to gag.. It was disgusting as I'm swallowing it it made me feel sick as I was swallowing it
I've got my head away from his dick
It's all limp now
I'm standing up and I couldn't get away from him fast enough
I was out of his house basically running down the street
I never heard from him again
