義父が大学から帰宅すると私を犯し、私の膣の中に入ってくる

I came home from college and my stepfather was waiting for me very hot, he took me to mom's room and started fucking me hard, he made me cum twice and I ejaculate a lot of milk inside my vagina, he doesn't care about anything anymore, look if he gets me pregnant, what do I tell my mom
