i was playing the devils bagpipes
Blowing a guy while he has a dump rearing out of his rectum...You push the breaching dump back in with your thumb, or for experienced piper's, a toe. Then the male will produce a low bellowing sound. This is the devil's bagpipe.
"Yo, dude, did you get a B.J. from that chick?"
"Nah, man...even better...she was blowin' my rod and then I felt a turtle head pokin out and she pushed it in with her thumb...I made this weird whale-ish kind of sound...I had heard legends of the devil's bagpipe, but never experienced it. It was so awesome!"
