Investigating the lingerie preferences of stylish girls on the street! What kind of underwear do they usually wear? We ask about fashion points, three sizes, erogenous zones, and whether they like toys. The girls are initially confused but eventually agree to participate in adult toy development monitoring for pay. They can't help but feel it, and their suppressed voices start to leak out. "Where does it feel good?" "Come when you're about to cum!" They insert a cock right away, feeling the sensation of a foreign object, but the girls can't hold back their excitement and keep feeling it...
