A really disappointing night

It was great until we got back to his bedroom and it was really disappointing in what happened,, basically it was over before it had started

I was in this bar and I really fancied this guy I had a couple of drinks so I had the courage to actually go over and talk to him,
Which actually made a change,,
As I genuinely never went over to talk to guys I was scared of getting rejected I suppose,
But having a couple of drinks already and Dutch courage is was over there talking to him,
He didn't stand a chance if I didn't say it myself,
I had him up dancing,, we had been dancing together for a while,, after this song came on that I didn't like I was taking his hand and I was taking him back to my table where my friend was,
We were talking together having a laugh together, dancing, drinking and eventually snogging the face of each other,
We were kissing each other more than anything else now,, it was getting rather passionate raunchy,, I stopped as I felt everyone was watching us,, but nobody was
Nobody could care less about what we were doing together,
If I was being honest with myself I was getting really turned on rather horny in kissing him, that's why I actually stopped kissing him,
It did feel good,
We were still talking when he asked me if I was wanting to go back to his house after here,, I agreed to it,
We were walking around to get a taxi constantly stopping to kiss each other,
Eventually we got a taxi back to his,, well his parents house,
We went upstairs to his room,, but what he didn't tell me was that he shared his room with his brother that was lying there on his bed at the other side of the room,, sleeping just now,
I felt rather uncomfortable with his brother being in the same room as us as we were going to be shagging each other,
I didn't want him seeing him doing it,
I didn't want him seeing me in that way being naked well semi half naked,
He talked me into it, I had taken my shoes off and taken my jeans pants off over my feet I was lying on his bed basically with my legs opened waiting for him,
He's got himself on top of me and he's putting it up inside me,, I'm lying there holding him as I can actually feel his dick getting deeper up inside me,
Then he let's out a big moan and he's just lying there on top of me holding me tight,
I'm lying there wondering what is happening then I felt this warm stuff inside me I gathered he had just came inside me as we are lying there
He's got himself off me and was saying I think you better go now,
I'm sitting up putting my pant jeans back on my shoes I get up from his bed getting my bag from the floor and he's taking me back downstairs and letting me out of the front door,
He's saying thanks for a great time as he was closing the front door behind me leaving me standing there on the path in front of his house,
I got my phone and phoned a taxi waiting for a couple of minutes before it arrived I was back home in the toilet basically washing myself between my legs and down around on my legs, before going into bed thinking what just happened with him
I still couldn't understand why he basically did what he did and then told me to leave,
He could have waited for a couple of minutes until he was hard again and we could have tried again,
