Through a used panties trading social network, I met a girl with an innocent smile and an incredibly cute vibe. When I headed to the hotel to inspect the panties she had worn and soiled as requested, she shyly giggled, "Ehh, this is so embarrassing~," every time I tried to examine each one—making her reaction utterly adorable. I thoroughly checked whether the stains were sufficient, sniffed for scent, inspected every detail, and was fully satisfied. Stains? Perfect. Smell? Excellent! I even got her freshly removed, still-warm panties she'd been wearing, leaving me completely thrilled. However, among the seven pairs, a few had only light soiling. So I asked her to re-soil them with fresh pussy juice, and she obediently agreed. From there, I escalated my demands under the excuse of further soiling the panties—masturbation, vibrator play, pissing—and she obediently followed every single order. This girl is definitely a total masochist. Finally, I made her straddle me in her stained panties and gave me a handjob through the fabric, climaxing directly onto the soiled panties. As an extra, I had her lick the cum off the panties, and she murmured, "It's sticky," so innocently. By this point, I couldn't resist asking her to take a masturbation selfie. She exposed her cute breasts, sweetly announcing, "I'm gonna jerk off now~," then began moaning as she twisted her hips with a toy, passionately rubbing her wet pussy. In the end, she used her own fingers to squish and squelch noisily, shuddering in orgasm while grinding her juices into the panties. After finishing, she softly said, "Thank you for watching,"—an overwhelmingly adorable sight!
