21-year-old Rinka Sakurazaka is a music university student with a pure demeanor hiding a wild side. Her luscious lips and sparkling eyes are utterly captivating. Dating her boyfriend for two months, this is their first overnight stay—except he’s also her boss at work. Shyly admitting, "I hope we do it tonight… (blushing)," she’s led into a special studio divided by one-way mirror. The shop is running a 5,000 yen cashback campaign for promotions, making pickups even more fun. Specializing in trumpet, she dreams of joining an orchestra someday. Under the influence of alcohol, she becomes lively and incredibly attractive. When shown the vibrator, she recoils cutely—"Wait, this is a dick, right?"—yet opens her legs on her own, revealing genuine, uninhibited lust. Soaked from fingering, she grins with anticipation as she straddles the machine. Crying, "It feels weird… it doesn’t hurt… No, no, nooo!" she still thrusts her gorgeous ass back, pure erotic perfection. Next, a 100,000 yen offer unleashes a giant bare cock—she instantly gobbles it down, delivering a tornado blowjob. Is she better at this than trumpet? Her pristine ladylike body jiggles beautifully in doggy style. Her kisses and nipples are ultra-sensitive! Arching like a shrimp on the bridge, she’s pounded from behind, filled deep with creampie. Burning hotter, she rides aggressively, grinding her hips with intense power. Vulgarly screaming, "I'm cumming! I'm cumming!" It's no surprise her face gets drenched in thick, spurting loads. Afterwards, she cheerfully says, "What’s next? I’m heading back to my boyfriend’s now." Apparently, this was the best sex she’s ever had. Sorry, boyfriend—she came first!
