As if she stepped out of a scene from youthful memories, the transparently pure schoolgirl Yumi Nijimura takes on a harsh challenge of being fucked nonstop for 120 minutes. Will her true nature, unimaginable from her innocent appearance, be exposed? Initially confused, Yumi says, "I've never had sex for two hours..." But determined to set a new personal record, she declares, "I want to make my partner say 'I can't take it anymore,'" and with a shout, she turns on the timer and immediately starts a passionate kiss with the male actor who dives in.
As foreplay begins, her slender body reveals unexpected E-cup breasts being groped, and moans of "Ahh, feels good..." escape her. When fingered through her panties, her shaved pussy peeks out, showing her arousal. Yumi displays an M-side, obediently following demands. When she cums from reverse cowgirl, she seems to like the sensation, saying "This is crazy! So good!" as she grinds her hips herself, reaching multiple orgasms. When the dick slips out, she reinserts it herself, and hearing her partner groan "Ahh..." as she grinds, she thrusts even harder.
Moving to the bed, the fucking continues. Her convulsing pussy is rubbed with fingering, and Yumi moans and squirts while writhing. When thrust into by the thick dick, she lets out loud cries. Even after cumming, she's fucked relentlessly, twitching all over as she orgasms repeatedly. After getting cum on her nipples and sucking the dick clean with a blowjob, she's exhausted from too many orgasms and whines at the 38-minute mark, "My body might not hold up..."
Then a second partner joins, and it becomes a threesome! With fingering and nipple torture, Yumi arches her back and stiffens, then nipple vibrators, a dildo, and a magic wand are added, making her writhe even more. Holding a dick in each hand, Yumi repeats "Feels good" and gets fucked from behind while giving a blowjob, writhing wildly. Thrust deep and hard, she cums many times, gets a creampie in her shaved pussy, and from too many orgasms and hard thrusting, she becomes so high-tension that she even pees. In the intense threesome fucking, she moans loudly, sobs while writhing in orgasm, and fights back by sucking dicks even as the thrusting never stops. Driven to the brink of consciousness, fucked relentlessly, she finishes with a facial from three dicks at the 120-minute mark. Basking in the afterglow of her first experience, Yumi still seemed like she hadn't had enough sex.
