NEO-606 - My sister's 3-day-old panties, the scent of first love in her discharge?!

I don't care for freshly washed panties. The real deal is the scent stained with her sweat, urine, and sticky discharge, right? I made Miho, who gets wet easier than anyone, wear the same pair for 3 days straight. I've captured the stains that get progressively deeper from day 1 to day 3 in extreme close-up. Enjoy the 'stain spiral' as she gets even wetter after being caught with white discharge.
