Bio: Born of a cheetah father and a whale mother, Debbie Throne was always a big kid. Her body’s natural tendency to accumulate blubber, as well as her unusual height for a cheetah, made her stand out in the schoolyard. Some bullies tried to get at her, but her thick skin, literal and metaphorical, made them quickly lose interest. She excelled at school, finding few distractions in friendships, which is something she would come to regret later in life. She graduated Valedictorian of her class and quickly enrolled at Providence University, far from her native town in the bustling city of Overland. It was there she made her first lifelong friend, a tigress named Lana N’Guyen. It was also during university that both of them discovered their sexualities: for Debbie, it was that she was simply not interested in sex or in committed relationships. She helped Lana pass some of her classes through cramming study sessions during which the tigress would bring all sorts of snacks. Debbie discovered her feederism kink when she started to pile on more than just the freshman 15, going well past the sophomore 150 and well into the senior 300. Several of those pounds were added by her first vore, a lupine alpha bitch from a sorority. Earning the nickname ‘‘fat cat,’’ Debbie graduated with a degree in economics and started working for Triple S Sweets, climbing and eating her way up the ranks until she caught the position of Chief Business Officer at the young age of 27.
Debbie is able to stretch her mouth to ridiculous proportions. This is because her skin beneath her fur is more akin to a whale’s belly skin, made to stretch after swallowing gallons of water and tons of krill. Her belly and breasts are devoid of hair, exposing the tan skin beneath. Finally, her stomach, also extremely stretchy, does not actually feel full until she is at the brink of collapse.
