This one song on camp 5

I really need to know which song this was.. There was a group of german guys on the left backside of camp 5. They played a german song that was about a blowjob and the sound girls do when they give one. It basically just goes „krrr krr krrr“ most of the song. The rest are more or less spoken words by a teen boy.

It was so freaking hilarious if you understand german.
