While casually checking out girls in Ueno, I was starting to lose hope after not finding anyone particularly attractive—until I unexpectedly met her. A cute girl wearing a spring-like gray jacket and a patterned skirt instantly caught my eye, and I approached her right away. She boldly responded, "Right now, I'm looking for amateur bikini models!" Using shopping expense support as an excuse, I managed to invite her to a hotel. As it turned out, she was an absolute veteran. With over triple-digit sexual partners and experience in the sex industry, she even shared stories of participating in 8-man couple-only orgies. Realizing someone like her could handle a little craziness, I nervously removed her underwear, had her get on all fours on the bed, and cautiously observed her reactions. She remained completely calm, even when sliding off her panties. She laughed and seemed to enjoy telling me to show her my dick. A born-out pervert, she instantly got turned on just seeing my cock, getting herself into full readiness. My dick swelled up more and more in response, becoming rock hard. Finally, she cheerfully shouted, "Here I come~!" and dove right in.
