I truly believe social media has become a wonderful part of daily life. Using it as a tool to fulfill my fetishes fills me with endless gratitude. My most frequent search history includes teenage girls, uniforms, short hair, underwear—especially stained panties. Recently, I discovered someone selling indoor shoes on social media. Browsing through accounts, I eventually found posts that perfectly matched my kinks. I was both surprised and aroused to see so many women—from schoolgirls to married women—selling their used panties. For women wanting extra pocket money and guys like me with slightly perverted tastes, it's a perfect win-win situation. I immediately posted: "Buying used, worn panties. Please DM me." I desperately wanted this girl's panties. I even checked her pricing. A bra-and-panty set was 20,000 yen, panties alone 15,000 yen, just the bra 12,000 yen, and socks 8,000 yen. Additional options included: worn for 2–3 days (+5,500 yen), worn for 6–9 days (+2,000 yen per day), one masturbation session (+6,000 yen), and no wiping after masturbation (+8,000 yen). She noted prices were negotiable and extra private options were available. I quickly matched with "Rui-chan," a youthful girl in uniform with long limbs and a cute short haircut. She proactively suggested the price would increase if she handed over freshly removed panties—clearly a high-quality find. I agreed immediately and arranged a meeting. I couldn't wait to see her take them off, to sniff the warm, freshly worn panties. In a secluded spot, she removed her panties and handed them to me. Ahh, my mind spun out of control… dopamine flooded my brain. I couldn't resist sniffing—ahh, my head spun again… dopamine surged, and I could feel my cock perk up with excitement. After negotiating for extra color, we nervously walked to a hotel with me going commando. My dick was rock hard, constantly wondering if her pussy was peeking out from under her skirt. For an additional private option, she let me closely inspect her bare pussy, and ultimately, we successfully had sex. I put on my favorite panties, slipped under her skirt, and gave her cunnilingus—reaching the peak of my life. I sniffed inside her leather shoes, of course sniffing her socks too. Ahh, fantastic—my brain juice and cumshot exploded in huge amounts. I could get addicted—even if it meant getting caught. I know it's wrong… but I can't stop these feelings. I'll continue my research without pause.
