Recently, my sexual desires have become uncontrollable. While browsing the internet, I found an SNS account that perfectly matched my fetish. Seeing various women—from female students to married women—selling used panties made me realize this was a win-win situation: women wanting extra cash and someone with my slightly deviant tastes. I immediately created an account and posted: "Buying used panties. Please DM me." After thoroughly analyzing the panty market, I listed my desired purchase prices: bra and panty set ¥4000, panties only ¥3000, bra only ¥2000, socks ¥1000. For additional options: worn 2–3 days ¥1500, worn 6–9 days negotiable, masturbated once ¥1000, wiped after masturbation ¥2000. I noted that prices could be adjusted through negotiation and that extra private options were available upon request. The first match was Ami-chan, who looked great in a uniform. She was a high-quality contact who even asked in advance if the price would increase if she handed over freshly removed panties. Of course, I agreed, and we arranged to meet. She was a beautiful girl exactly my type—slender with long, delicate limbs, giving off a trendy young girl vibe. In a secluded spot, she actually took off her panties and handed them to me. I couldn't resist sniffing them—there was a faint scent of sweat and young girl, utterly irresistible. She negotiated to add extra features, and we nervously walked to a hotel with her going commando. On the stairs, it was barely visible but enough to keep me fully erect. With additional private options, I got an up-close view of her bare pussy, and ultimately ended up climaxing. It was an amazing experience. My brain juice and cum gushed out endlessly. I definitely want to keep doing this.
