A couple of times a year, I see my aunt and uncle. One day, my uncle invited me to go to an onsen. Apparently, my aunt had asked him to invite me. While bathing together in a private family bath, my usually prim and proper aunt transformed into a beast, stealing glances from my uncle to fondle my dick and lewdly seduce me... Please enjoy the steamy eroticism of a middle-aged woman in her prime, frustrated with unmet desires.
