YSN-664 — I'm being kept as a pet by my new sister-in-law who's not very smart but has a strong sex drive. (Haruno Ando)

Haruno, the lazy and promiscuous sister-in-law, doesn't work and shows no interest whatsoever in anything other than sex. Although she usually has no motivation to do anything, her sexual desire is abnormally developed, and she can empty her brother's testicles with her oral sex techniques and tight vaginal grip.
