I was visiting my mum and she was living in the house I grew up in. My brother was there but my mum wasn't, and Yu Lee was with me.
I'm not sure who invited her but after a little while a fat girl came to the house and someone commented that they "knew what was going to happen". A bit later my brother started making out with the fat girl, and then they announced that they were "going up stairs".
I don't understand why but they decided that they were going to go to my room, and my bed wasn't made because no one had been living in there so I followed them upstairs. First I told them to make the bed but then when it was clear that they weren't going to do this I went in after them, and while they were kissing quickly put a sheet on the bed.
At that point my alarm went off and woke me up.
