"My little sister" is sloppy. She gets envied by others, but at home she's really shameless and has no cuteness about her. She plays with her smartphone while wearing nothing but panties, or lounges around without a bra letting her breasts hang out. Even though I'm her brother, I'm still a guy. If panties and breasts are waving in front of me, it's only natural to touch them. Since I have nothing better to do either, I reluctantly keep doing lewd things with my spoiled and lazy little sister just for her sake. My sister enjoys it too. She says 'no no' at first, but in the end she always moans 'yes yes'.
