What story is this?

Trying to remember a story I read a while back:

It was about a boy who became a cheerleader and had a slumber party with them, where it was revealed that the football teams performance was based on the cheerleaders performing services for them before games. It was then revealed that the star quarterback was gay, and it would be up to the boy to help "get him ready" for the game.

Other tidbits:
-the boy had a twin sister, who would be given a spot on the cheerleading squad if the boy performed his task
-he shaved all his body hair, did his hair and makeup before going to the slumber party
-the mom in the story was a serious cheerleader herself, and took the opportunity very seriously when she heard that both her son and daughter could become cheerleaders.

If anyone has any idea what this story was called (if you could find anything in what I just wrote :P ), please post it here. With the search bar not working anymore its become a lot more difficult to find the stories I want to re-read
