Highly educated big-titted college girl appears in this electric vibrator challenge—she can win 1 million yen if she doesn't orgasm! Will her insatiable academic drive translate into endurance? A refined young lady raised in an upscale neighborhood, Asaka is a fourth-year student in the Faculty of Contemporary Liberal Arts at a women's university, already with a job offer from a major securities firm. Her future husband is likely to be an elite as well—she seems out of reach. But statistics say the more refined the lady, the naughtier she gets, making us desperate to ravage her completely. She readily agreed, believing she was signing up as a massage device tester. Even after learning the real rules—no orgasming with the vibrator or she gets 1 million yen—she confidently says, "I think I can endure it." Handcuffs suit her perfectly as we torment this elegant woman. Despite her bold attitude, even weak vibrations make her pant "haa, haa." Her sensitivity is incredible—her inner thighs twitch in distress. When we attack her G-cup breasts with a pole vibrator, she moans despite trying to hold back, her pale pink nipples exposed. On all fours, she receives intense vibrations, seemingly enduring—yet her hips writhe. Once we remove her soaked panties, she can't hold back and squirts uncontrollably. Her disheveled, gasping form is incredibly erotic. She's dripping more than ever, completely entranced by the vibrator. Unsatisfied with just the vibrator, we plunge our thick, hard cock into her slippery pussy. In missionary position, deep grinds send waves of pleasure through her. Her eyes roll back as she writhes, making our cock even harder—multiple creampie loads follow. We stand and restrain her, adding follow-up vibrator shocks that make her legs tremble. As she collapses, we force deep throat—her gagging throat vibrated mercilessly, revealing her ultimate masochistic pleasure. Doggy style leaves her lower body shaking violently. "Ssssimply hitting deep inside~" she screams in orgasmic frenzy—a true masochistic slut born from the Erotic Liberal Arts Department. Rear cowgirl, power fucking, missionary—endless cock drilling. We make her cum repeatedly, then blast her face with massive amounts of cum, her delighted expression priceless. Behind her refined appearance lies an insatiable sexual appetite—she's no longer a lady, but a cum-drenched slut. While shocking her with more vibrator, we ask how she feels: "Moo w," she giggles, "I couldn't endure cumming, it's so frustrating." She laughs, admitting she kept going because it felt so good.
