The first part of a multi-part, ongoing, really-quite-long collaboration story with marcusquinn featuring ponies getting fatter than their wildest dreams, featuring such fantastical things as weight gain, romance, and character depth!
Credit where it's due, this chapter was predominantly written by marcusquinn over there. Give him the niceties.
