Standard MP4 Version- I sit on my comfy couch and expel many, many substantial Belches. I let loose over and over and some are absolutely colossal! Every one is as satisfying as the last. Trust me you will love this non stop, uncut belching clip, it is filled with lots of choice burps, and pretty much no downtime. Plus it doesn't hurt that I am wearing my favorite push up bra to enhance the viewing experience for all my burp loving fans who also enjoy a nice perky set of breasts.
