Shimazu Kaoru, a busty beauty whose L-cup bra is beginning to feel too tight, appears in a 120-minute nonstop sex project! Shimazu candidly reveals that she had a rehearsal with a man 20 years younger than her just the day before, grinning with embarrassment as she recalls the affair! So, the director, excited to see what she can do, brings in a young actor who is the same age as Shimazu's daughter. Shimazu, powerful and in top form, doesn't seem to care about the age difference between them, giving him a deep kiss and not stopping to grope his crotch! She caresses his testicles while happily giving him a blow job, then wraps her proud breasts around his erect penis for a titjob. As she's fingered, Shimazu cries out in excitement as she slides off the sofa, squirting in ecstasy! Unable to wait for penetration, she wraps her arms around the man's waist, pulls him closer, and as they unite, she instantly transforms into a woman, groaning in pleasure... With all her nerves focused on her pussy, Shimazu goes wild, throwing her huge breasts and convulsing her body until the cum inside her overflows. When she's taken by new men, a hellish pleasure awaits, where she's made to cum over and over again with toys! Her hair is disheveled from the excruciating ecstasy, and with her face on the verge of tears, Shimazu lets out a death cry and loses her sense of self-pity! While Shimazu desperately tries to refrain from caressing her, saying "It's okay now...", the sex-crazed male actors are fully erect and ready to go! "Thanks for today, I'm a mature woman..." Shimazu surrenders and starts to finish on her own, but the male actors calm her down and she enters into a four-way orgy! With semen all over her face, Shimazu's face is as shiny as if she's been smeared with beauty serum, bringing the 120 minutes to a close!
