At the hospital run by the beautiful doctor Yui Hatano, creepy patients constantly flock to seek her out. Exhausted by this daily routine, she one day awakens to a hidden, perverted side within herself. With men of all undesirable types—masochistic guys, extremely obese men, short creepy guys, otaku types—Dr. Hatano engages in sloppy tongue kissing, saliva exchange, and passionately licking each other's tongues while sucking on gums, driving them all to ecstasy. Through these encounters, she gradually rediscovers her true nature.
