I kissed my brother's best friend....Now I feel guilty.

I have know my brothers best friend for 4 years now(he is 2 years older than me) and last night my brother had a few friends over for the night and some of them went into the guest room to sleep with my brother but my bros best friends John and my bros other friend Dave were sleeping in the living room...Well my brother was asleep and I came out into the living room cause I couldn't sleep(it was around 2 in the morning) and I was going to get a movie to watch and John and Dave were still awake talking and then we started talking and John said "do you want to watch the movie out here cause we are really bored too" and I agreed... So we were watching the movie and Dave fell asleep so it was just me and John... I was sitting on the ground and he was sitting on the couch he asked me if I wanted to sit on the couch with him... And I figured nothing bad would happen cause his like my second brother...

we were watching the movie when he randomly put his hand up my leg and I asked him what he was doing and he leaned over and kissed me...I was so shocked I didn't know what to do... I pulled away and he just asked me what was up? And before I could answer he kissed me again... And he wouldn't let me pull away so I wasn't really kissing back( I was kind hoping that he would just stop...He didn't) after a while I guess I just started to kiss back... There wasn't really anything that I could do about it cause every time I tried to pull away he would just start to kiss me again.

So now I feel really guilty about it cause I was always trying to save my first kiss for someone special... And I never really thought he would kiss me... So I don't really know what to do

Sorry the story is so long...But I don't know know what to do should I tell someone cause I don't want to be alone with him again...
