Movie name? (wasn't porn).

Hello everyone. Does anybody know this movie which a group of (i think) schoolboys gang rape a schoolgirl and then force brother of the boys who was upstairs hearing(or was trying to hear) music to have sex with her. and it seems the house belonged to family of those brothers.
Thanks.
P.S:it was in the xnxx.com videos a long time ago but i can't find it anymore and i couldn't find it's name either.
even the video could be useful.
