Yamamoto Kosaki, 47 years old. Normally works as an office clerk at a real estate company and is a single mother with one child. She has had perfect attendance for 15 consecutive years without any tardiness or absences. Her serious work attitude is renowned, but it all stems from her sense of responsibility as a parent. She told herself she must stay strong until her son grows up. However, recently her son has started having a girlfriend and doing at-home dates. When she returned home exhausted, she heard the moans of some woman leaking from her son's room and 'felt like it was all so ridiculous,' deciding to quit her job as a result. This time, she unseals the footjob technique that was thoroughly trained by her ex-boyfriend who is into feet! Returning to her former self who made men cum endlessly, she accepts another man's dick for the first time in 20 years.
