"My little sister" is messy. People envy her, but at home she's really messy, cheeky, and not the least bit Ke'ai. She plays with her phone with her panties exposed, and rolls around without a bra, not minding that her breasts are out. Even though I'm her older brother, I'm a boy too. If her panties and breasts are jiggling in front of me, it's inevitable that I'll touch them. I'm just as bored as her, so I have no choice but to always do naughty things to play with my spoiled, lazy little sister. But she's happy too. At first she says no, but in the end she's coming in a sweet voice.
