Starless 3 - Busty anime maid gets billiard balls shoved up her asshole

Yukito applies for a live-in servant job at a mansion, and at the interview he is pleasantly surprised that the salary is really high.

They both pass, but are they really prepared to handle the responsibilities expected of them in this mansion?
