Fat Little Milk Cow Bess (Patreon)

Bess used to be a highly intelligent, dedicated graduate student with a bright future in front of her.... until she volunteered to be part of Professor Joan's secret experiment to help improve lactation. But Bess had no clue that there would be so many unusual side effects. Now Bess is changing, in more ways than expected, turning into a busty, ditzy dairy cow. But Bess doesn't mind. She doesn't have the brains to mind anymore! A weight gain/stuffing story that includes lactation, breast growth, bimbofication, and cowgirl transformation.
