My son's girlfriend, with short hair, big breasts, and a youthful face, is so sexy that I can't resist. (Ii Ruka HBAD-740)

My son's girlfriend, Ruka, has been staying at our house a lot lately. Her cute face paired with her disproportionately large breasts and figure, coupled with her constantly lurking around the house, makes me unable to resist watching her. Every time she stays overnight, I can hear her and my son making love, and I have to desperately suppress the urge to peek... until one day, after they finished, I accidentally saw Ruka completely naked in the dressing room as she came to shower...
