I saw this movie in 2007 as I recall.

It is about this young teenage girl having oral sex with multiple boys in the school.

In one scene, there is this boy who blindfold her and take in to a cave or something where there are couple of  other boys and she ended up giving everyone oral sex to everyone.

Rest of the school get to know about this as her name was written with a penis on a window of a school building.

Towards the end of the movie, there was a scene where this girl giving oral sex to a boy in a garden and she wipe out her mouth like she swallowed it after he came in her mouth.
