GG-128 Aoyama Nana, the overly serious busty housekeeper

Nana is a hardworking and obedient housekeeper to her master, but because of her overly serious personality, she even accepts her master's sexual requests as part of her job. When he asks her to "wash his back," she is forced to wash his body, and when he asks her to "check the condition of his lower body," she is shown his bare penis and even has sex with him to see if it works, and she faithfully carries out her master's orders!
