Dr. Sugimoto's Lecherous Treatment (杉本女医の淫乱痴療 Sugimoto Joi No Inran Chiryō, eng. Female Doctor Sugimoto's Lecherous Treatment) is the tenth UMEMARO 3D mini-movie collection and eleventh release overall, released on December 24 (Christmas Eve), 2010. Featuring Shoko Sugimoto in her second headlining role, it is the first UMEMARO 3D release to not introduce a single new character, coming two years after Twin Succubus's record-setting five new characters.



"You woke up to find yourself lying on the bed of the nurse room. Then you saw a sexy feminine doctor; she was looking you down with her beautiful eyes. She started examining you to give you a "special" treatment you hoped for..."


Shoko is treating a patient (whose identity is deliberately hidden for the majority of the game) brought to her by Miyuki Kageyama, complaining of a headache. She treats him through the tried-and-true manner of sex, beginning with a blowjob, moving on to a titjob, and eventually full-blown sex in a variety of positions. When the patient climaxes, Shoko lies back on the bed, satisfied. However, the patient stands up as a sigil appears on his chest, and his penis splits vertically into two. He grabs Shoko and begins to rape her, penetrating her vaginally and anally at the same time, until he climaxes several more times, incapacitating her. Upon concluding his work, the camera pans up to reveal that the patient is Shinnosuke, reinforcing this by showing archive footage from Twin Succubus. Shinnosuke then turns to dust, crumbling into a pile on the floor. Outside of the room, Mimi leaves, her work apparently done.

The game ends with a trailer for Game of Lascivity OMEGA 2, which would not come out for two and a half years.


Though featuring less direct interactivity than previous installments, Dr. Sugimoto's Lecherous Treatment uses the same system that powered Lewd Consultation Room and Twin Succubus. This release served as a stopgap between Game of Lascivity OMEGA and Game of Lascivity OMEGA 2, serving to explain Shoko's absence from the second game. As it featured Shoko as the sole headliner in the game, Dr. Sugimoto's Lecherous Treatment was incredibly well-received, though much of the fanbase was wary of UMEMARO's continual introduction of fantasy elements to his works.

Dr. Sugimoto's Lecherous Treatment was given a Western subtitled release shortly after its Japanese release. Over six years after its initial release, without any advance notice, the Japanese unsubtitled version of Dr. Sugimoto's Lecherous Treatment was released on the English DLsite page.


  • Dr. Sugimoto's Lecherous Treatment is the first - and only - mini-movie collection to feature a previous UMEMARO girl as the headline character in Shoko Sugimoto, who previously appeared in Lewd Consultation Room.
    • As a result, this game, OMEGA 2, and The Chiropractor are the only UMEMARO 3D releases to not introduce a single new character, if Tagishi's appearance in OMEGA 2 is discounted.
  • For the first time since Mai and The Crazy Female Teacher, Dr. Sugimoto's Lecherous Treatment arrived in the same year as another release, that being the Project Work OMEGA, which was released eight months earlier. This would later occur once more with Work in Progress and The Chiropractor, both of which were released in 2014.
  • Dr. Sugimoto's Lecherous Treatment is the first UMEMARO 3D release since Sasa to not be longer in terms of animated scenes than the release preceding it.
