NDRA-043 Stepmom's HD Underwear

"Step-mother's panties HD. No matter the era, technological advancements always start with eroticism." I'm a NEET living with my father's remarried wife and recently have been obsessed with a certain malicious act in my daily routine. It involves "stealthily taking my chaste step-mother's panties from the washing machine and intently staring at the stains and texture of the crotch area, comparing it to her everyday appearance." This is a professional-level perverted act.
