NEGACCESSVERSE - Britt & Catty - Good Kitty/Bad Doll (Patreon)

The calm and responsible Caty does not have an easy life. In addition to  being enrolled in AHS, a school for mutant girls that has fallen into  disrepair, she must endure the continuous jokes of her lazy and carefree  adoptive sister Brittany. 

In order to get more subsidies from the government, Caty's parents  adopted the troublesome modular girl, who has become a headache for the  quiet cat girl.  More than once, poor Caty has found a middle finger floating in her cup  of milk or has been bothered by disembodied hands under her blouse.  

Britt loves teasing her sister and is behavior that her carefree  adoptive parents seem to turn a blind eye to.
