[Reducing Mosaic]SDJS-190 Third year at the company, Assistant Director Tamayo Morikawa of the Production Department. A document of our first overnight experience together from after work until the first train.

Two years have passed since I joined the company, and Morikawa-chan has become like a senior. This time, we will find a virgin in the company and challenge the brush down. Morikawa-chan's technique, whose SEX is growing little by little, makes her junior faint in agony! ? From the end of work to the morning, gentle instruction! Please see how you do your best as a senior even though you are nervous about your first experience!
