I couldn't believe I did it for a dare

I was at my friend's house and we were playing truth or dare with her younger brother

I was round at my friend's house and we were drinking and playing truth or dare with her younger brother
I'm 21 my friend was 22 and her brother was only 17..
And we were drunk playing truth or dare which isn't a good idea..
It was the usual questions at first.. first time you lost your virginity.. where it was, who it was with,
The usual stuff playing the game along with stupid dares at first..
We had been playing it for a while now and we had drank more alcohol
When my friend dared me to give her brother a blow job..
I was shocked in what she had said at first I honestly wasn't expecting that
But I actually agreed to do it to her brother but she was wanting to watch I had to do it in front of her
Her brother was lying down on the floor his boxers jeans down below his knees and I'm kneeling down beside him leaning towards his cock putting my mouth down around on it
I'm actually moving my mouth up and down on his cock looking at her as she was sitting there watching me giving him a blow job
It felt so weird giving him a blow job as she's watching me
It wasn't long before he's coming inside my mouth I've got my mouth down around on his cock as he's coming
I'm letting him finish off inside my mouth before I pull my mouth away swallowing his come sitting up looking at her as she's sitting there smiling at me
Her brother was sitting back up leaving his boxers,jeans down below his knees,
I'm taking another drink getting rid of the taste of his come from my mouth
My friend looked at me saying I think he enjoyed that
I'm looking at him as he's smiling at me saying it felt great thanks
His cock was rock hard again it didn't take him long to get hard again.
That's when he dared his sister to lick me out on my fanny
She's agreed to it straight away asking me to get them off
She's basically telling me to take my jeans and pants down
I'm just looking at her saying no I don't want to buy they are telling me that it's a dare and they have to do it
Being drunk I actually took my pants jeans down lying there with my legs opened and she was lying down between my legs over my pants jeans and she had her tongue going up inside my fanny
She's licking around inside my fanny it actually felt so good
Then she's sucking on my clit I'm wriggling about on the floor it was so intense I had never experienced anything like that
I actually came as she was sucking lickings on my fanny
As I'm lying there her brother was wanking himself off over my face he's actually came all over my face I had his come running down all over my face
She's got a hankie and she was wiping it off my face as I'm still lying there on the floor
Telling her brother he shouldn't have done that
I'm saying it was ok it wasn't the first time a guy does that to me and it's certainly not going to be the last
