OK... so im looking for this sound effect... Its off a few anime series involving a bit of ecchi... I ask on this thread cause im desperate and /r/ is a bunch of balls !!

It usually happens when the guy walks in on one of the female characters getting changed or about to get into the bath or a pantie/underwear shot and as it happens there is like a voice that goes "OOOHHHH YEAAAHHH!!!" while the shot pans over the ecchi scene... can /r/ please help me either find the anime with it in or give me a link to just the sound !!!


PLEASE !!!

OR
what Episode in Amaenaideyo! Katsu!! OR Kampfer does the OH YEAH sound effect play ???
