We were at a resort in Bali with some other friends.
One day he went out to buy food, so we ask him to buy back for us.
When he got back, he came over to my room to pass me the food. So
we just ate in my room. After eating felt lazy so sleep lor. It is
not the first time we share the same bed. I knew him since primary
school.
As we talk in bed he moved closer and closer then started to caress
me. I dunno wat came over me and I let him continue.
Soon our clothes are off and too late liao.
I do not now how to behave around him now. 
If he likes me, I am sad to hurt the GF.
If he doesn't like me, then I will be hurt.
