A spin-off of the popular "Library Series"! The new hunting ground is a museum shrouded in silence! A man gropes the breasts and crotches of a high school girl and the receptionist who works there in the shadows. The woman resists but feels pleasure and moans while worrying about her surroundings. When he tries to penetrate her, she reacts with a trembling body, and her crotch is soaked that she starts to overflow with whiter juices than semen.
