002HODV-21855 My NEET sister who's squatting in my shitty apartment is shaking her huge tits around without a care, and I can't take it anymore. ★Nanami

My sister suddenly said she wanted to move to Tokyo and rolled into my apartment. She's a complete indoor type of hikikomori with social anxiety. Her breasts are the only thing that have grown nicely, bouncing around carelessly. She always lounges around in a sloppy and erotic way, so I can't help but notice... I was caught using my little sister as material for masturbation, and then she actually tried to seduce me! My libido exploded!! "If you don't teach me about sex, I might get pregnant by some weird guy."
