She shows her sister's boyfriend through a chain locked door and cuckold her! My sister and I are good at studying, smart, and can always compare themselves to me. He's extremely proud of his handsome, rich boyfriend. What's more, she wears a cat in front of her boyfriend and has a completely different attitude. In order to somehow clear up her grudge against her, she lets her go out for a while and locks her up, seduces her boyfriend and shows her sex with her through a chain lock!

I am always able to compare myself to my clever and easy-to-study older sister. What's more, my sister has a handsome, rich boyfriend, and she's super bragging about it. In front of him, he sees his sister wearing a cat and acting completely differently, and his daily grudge explodes! In order to vent his frustration up until now, he lets his sister go out a little, locking her up and locking her out, then seducing her boyfriend and taking her to have sex with her, but that alone isn't enough, so she shows off her sex with her to her through a chain lock!
