JG,
Neither Sheri’s Ranch nor any other Nevada brothel has a Courtesan that precisely fits your description. Normally a BBW is classified as a full figured or pleasingly plump woman. Sheri’s Ranch has voluptuous Courtesans that may be considered BBWs. However, these Ladies are in great physical shape and definitely not obese. Amber Lynn and Red Diamonds are two Sheri’s Ranch Courtesans that are exceptionally beautiful Ladies and delightfully curvaceous too.
Amber Lynn contributed to a blog “Perfectly Thick Booty, Big Breasts, and BBW” that may be of interest because it’s pertinent. http://newblog.sherisranch.com/sex-and-beauty/perfectly-thick-booty-big-breasts-and-bbw/
Red Diamonds contributed to a blog “The Goddess of the Big Breast Fetish” that is relevant too. http://newblog.sherisranch.com/fetish/breasts/
