A 40-something married woman named Takashiro Keiko, who has two middle school-aged children and no history of infidelity. However, she has been sexless for about 5 years... It must be unbearable for her to feel such longing. This time, for the first time, she lets a man other than her husband touch her body, engaging in sex and challenging her first ever deepthroat. Perhaps because she sometimes watches adult videos without any other stimulation when she masturbates while nobody is home, she quite enjoyed the filming process. Her body is burning up, the first deepthroat sex of this clear-skinned, elegant lady! Just how does the taste of sperm compare?!
