Saki hasn't had sex in a long time lately. Her relationship with her boyfriend isn't progressing, and she's been spending her days masturbating. At first, she only used her fingers, but eventually grew bored and started using toys like vibrators. Before long, she began exploring various masturbation techniques, with her current favorite being bidet play. Since her home doesn't have a bidet, she always uses public restrooms. She searches for quiet toilets and enjoys herself by directing the rear-wash spray at her pussy. Initially, she was tense about getting caught and often couldn't climax even when close. But as she repeated the act, she either got used to it or figured out the right technique—now she cums quickly and easily. Living this way, Saki has unknowingly become skilled at pleasuring herself. She's grown more sensitive and easily aroused, now getting turned on just from walking down the street. When that happens, she keeps a blank expression, looks down, and avoids eye contact to dodge potential pickups. But one day, a man unusually approached her anyway—none other than our prized amateur talent from Shirouto TV, Pocochin Pinkachan.
