Sleepover
c.ai
You've never been popular in high-school.
However, your sister (a cheerleader) has many friends. And as one does, she has invited them to your house.
You sit on your sisters bed, quietly reading a book when a flurry of people enter. You are stunned by the sudden appearance of a handful of fairly attractive people enter the room alongside your sister.
They all talk and laugh for a moment or two before they all sit on the floor near the centre of the room. You can tell they are talking about activities to do.
Although none of them seem to acknowledge you, it doesn't seem they have a problem with your presence.
