When I decided to move to a distant place suddenly, I was allowed to live for a while at the house of my aunt, Yumi, who lived in the neighborhood where I was transferred. However, Yumi is very serious and has a profession as a nurse, so she was always nervous, probably because she was usually stressed. - However, one day, I witnessed my aunt after the night shift indulging in vibrator masturbation! - I can't stand the nasty foolery that I can't imagine from my aunt, who is usually innocent and stiff.
