When your getting head and as you jizz you pinch the girls nips and the combination of the warm liquid in her throat and her scream make the Chewbacca noise
Brooo I gave Karen a Chewbacca scream so bad she took the kids and left me.
A royal screaming fart that : you only cut lose once, that builds to a crescendo by the second, that you release only after you’ve cased all perimeters , looked thru an infrared scope , verified that all the batteries in the fire detectors around you are still charged , thrown a Hail Mary pass & had a personal consult with your Ring Home Security System.
I was finally able to let lose on a Screaming Chewbacca Fart once I sprinted thru the entire concert hall & found the door to the sound proof recording booth.
