Giving a blow job

I had just started seeing this guy and I actually got caught with his parents giving him a blow job

I had just started seeing this guy we had been seeing each other about twice a week now but we still haven't done anything apart from kiss each other and cuddle up with each other..
It wasn't for the lack of trying on his part he's constantly touching my boob's or trying to get his hands inside my knickers but I didn't want him to as I was on my period at the moment..
I've told him about having my period and he was asking me if I didn't mind if I could give him a blow job just now
I had never done it before I didn't know what to do I felt embarrassed about not knowing what to do
But I was going round to his house and I'm building myself up to give him a blow job this night I was feeling really nervous embarrassed about doing it
I don't know why I was so nervous about giving him a blow job but I was
Anyway I was round at his house and since his parents were away out for a wedding reception they told him that they wouldn't be back until early hours in the morning
We were in the living room kissing it was getting very passionate between us as we were kissing each other his hands going all over my body
I had to keep reminding him that I was having my period as he was constantly putting his hand down into my knickers
I could tell that he was getting annoyed with me probably frustrated with me in not getting his end away
He's lying there on the sofa I'm lying there with my head down on his stomach as I was touching him up with my hands on his dick
I think he was enjoying it with all the moaning he was making
That's when I put my mouth down around on his dick sucking licking kissing on it licking on it down to his balls
Licking sucking on his balls
Then I was wanking him off into my mouth he's got his hands on my head holding my head down as I was just wanking him off into my mouth as I was sucking and licking around on the tip of his dick I was putting my tongue down inside the hole on his dick
He's moaning so loud then this stuff was coming into my mouth it was googey warm and tastes absolutely disgusting
I didn't like it he's coming as he's holding my head as he's humping my mouth
That's when the door opens and it's his parents I'm lying there with my mouth down around on his dick mouth full of cum as his parents are standing there looking at us both
He's just holding my head down as my mouth was down around on it
Mouth full of cum and his parents just standing there looking at us
I could actually feel him still coming into my mouth I thought he was never going to finish
His parents went out closed the door as he's still holding my head down humping my mouth he eventually finished I'm basically running to the toilet trying not to swallow his cum it was disgusting
I got to the toilet spat it out
I could hear him and his parents shouting at each other lucky my shoes jacket bag were next to the door as I went out of the house and got into my car and drove back home
I never heard from him again to be honest I was so glad as I couldn't look at his parents when they had seen me with a mouth full of dick
My first time giving a blow job and I actually got caught doing it
