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. Only her breasts are well-developed, bouncing around carelessly. She always lounges around in a sloppy, erotic way, making it hard not to notice... I was caught using her as material for masturbation, and to my surprise, she counter-seduced me, causing my sex drive to explode!! "If you don't teach me about sex, big brother, I might get caught by some weird guy and end up pregnant."
