I ended up taking care of my niece, a female student, at home for a while. She used to say things like 'I'm going to marry you, big brother◇' and was really cute, but she's become quite the brat after not seeing her for a while and won't even talk to me. Right now, she's not eating the meal I prepared and is lying on the sofa playing mobile games. ... Hey hey, your panties are showing. She's either careless or doesn't see me as a man, but if she's going to show off her cute ass like that, I'll have to educate her!
