"Oh, so you used your powers to eat him?" Her mother giggled, "well Kat, you're now an adult witch, I can't treat you as my baby anymore, so have fun using your powers" she winked to Kat.
"Yes Kat, now you have to take the responsibility of your magic and use it as you fit" her father added, "and... We always wanted two daughters, but we weren't lucky with Dan, so you kinda did us a favor haha" he laughed with Kat and her mom.
"Okay darling, now your dad and I are going to go to a restaurant together, just take care of the house while we're in the restaurant" her mother said.
"Sure" Kat nodded calmly as she expected a punishment from her parents but reacted way better than she expected, now the house was all hers while her parents were absent.
Some hours passed while Kat was relaxing in her bed watching TV and tested her spells, then she felt something in her ass wanted to go to the bathroom, "well, your time is over Dan" she giggled while rubbed her stomach, she wanted to see the useless mass her brother turned into, so she went to the backyard instead of the toilet. Now in the backyard and after gathering some toilet paper from the bathroom Kat removing her pants and panties exposing her ass and vagina ready to expel her brother.
Kat got into position and began to push a little from her butt while feeling how the rests of her brother started to come out, as the rests came out she began to push harder until all was outside from her asshole so she cleaned her parts and stood up looking the pile of shit with some bones and skull that was her brother. "Aaaah Dan~ I really feel better know.
Just look at you, thinking you could get rid of me and see how you ended" Kat laughed, "I'm going to leave you there if my parents are curious of what I did with you, so goodbye pile of poop!" She entered the house holding her pants and panties, leaving Dan as a useless and forgettable intestinal waste in the backyard while Kat took a shower and think what to do next.
