I (68M) bent over my girlfriend (14F) and took the jug of petrol and stuck the nozzle into her ass and started letting the petrol pour in, she told me to stop but I thought she just wanted more petrol.

Yesterday she started acting really weird and she said her stomach and head hurt, I thought she needed more petrol so i bent her over again and poured more petrol into her ass. I put in a buttplug so none of it would come out and sat with her for a few hours to make sure the petrol really sat inside. Today she was in even worse condition but I thought she needed more petrol, however she said she didnt want anymore and she sounded serious.

Should I keep pouring more petrol inside her or should I just stop?

AITA for not stopping and pouring more petrol inside her?
