Shiho is a bioscience researcher. She graduated from graduate school and has been working as a researcher ever since. She loves and enjoys research, and it's wonderful to be in an environment where she can enjoy her work. She hasn't had a boyfriend in a year, but she does have a lot of sex. Shiho describes it as "a sex friend." When I asked her about her masturbation habits, she revealed that she uses toys, suggesting she's quite skilled at masturbation. She even masturbates with a vibrator, as you'd expect from a researcher, demonstrating a strong intellectual curiosity about sexual desire. Since female researchers are rare, it's interesting to wonder what motivated her to apply for adult videos. She explains that she "recently discovered the AV profession..." It's no exaggeration to say that curiosity is what drives her. She probably never expected that such intellectual curiosity would lead her to become even more obsessed with sex. Enjoy her ecstatic fascination with the big-cocked actor's penis, even receiving his cum on her face and giving him a clean-up blow job.
