A 19-year-old Signboard Girl At A Home-delivery Bento Shop Is Turned Into A Sex-processing Masturbation Doll By A Group Of Hard-working Construction Workers Using Sleep Locks.

Kanna (19) works as the face of her family's bento shop. Her brother, one year older, works at a factory. There are frequent orders from her brother's workplace, and she knows his coworkers by sight. One day, she was invited to a drinking party that her brother would also attend, and feeling completely at ease, she agreed. But it was a trap to assault her. Her drink was laced with sleeping pills, and after she fell asleep, she was passed around by the men.
