Tsukino is the only woman in the department, yet she is so quiet and plain that she is barely noticed. One kind word from a senior coworker changes everything: love letters, handmade heart-shaped lunches, sex at the office, blowjobs followed by swallowing, and pregnancy-risk creampies. Beneath her reserved exterior is an obsessive sex drive, and she seems to grow more beautiful each time she takes him by force. He knows it should stop, but being licked all over and repeatedly used feels so good that he wants her to break his body and mind completely.
