A sex machine, also known as a fucking machine, is a mechanical device used to simulate human sexual intercourse.〔Leung, Isaac (2009). The Cultural Production of Sex Machines and the Contemporary Technosexual Practices. In Grenzfurthner, J. et al., eds. ''Do androids sleep with electric sheep? Critical perspectives on sexuality and pornography in science and social fiction.'' RE/SEARCH, ISBN 978-1-889307-23-7〕 It is a more sophisticated version of the vibrator. Devices can be penetrative or extractive. A typical penetrative machine works by the transfer of rotational or reciprocating force from a motor to a directional motion on a shaft, which is tipped by a dildo.〔Farrell, Lauralee (2007). Dream Machine. In ''The Best American Erotica 2007'', p. 2077. ff., Susie Bright, ed. Simon and Schuster, ISBN 978-0-7432-8962-7〕 A hand-held modified reciprocating saw device is sometimes called a fucksaw〔Clark-Flory, Tracy (March 3, 2011). (The "live sex show" professor speaks. ) Salon.com〕 and a hand-held modified drill motor rotating device is sometimes called a drilldo.〔Arnott, Stephen (2010). ''Sex: A User's Guide.'' Random House Digital, Inc., ISBN 978-0-440-33437-8〕 An extractive device works like a milking machine and can be attached to the penis, breast, or other body part.〔Browne, Ray Broadus (1982). ''Objects of special devotion: fetishism in popular culture'', p. 49 Popular Press, ISBN 978-0-87972-191-6〕 ==History and use== The vibrator was originally invented for the treatment of hysteria in Victorian women through medical orgasm induced by clitoral massage. These early mechanical devices were much larger and more powerful than the modern vibrators and were first used by physicians and became popular in bath houses in Europe and the US towards the beginning of the 20th century. More compact, electrically powered versions later briefly appeared as health aids in department store catalogs. Modern automated erotic stimulation devices differ from vibrators because they penetrate as well as throb. These devices are sometimes used as part of auto-erotic or partnered bondage play. Teledildonics combine use of various sex machines and a web interface, used remotely by a partner.〔Blue, Violet (2006). ''The Adventurous Couple's Guide to Sex Toys.'' Cleis Press, ISBN 978-1-57344-254-1, chapter 6: Teledildonics toys: online sex for two〕 Today the sex machines on the market include vacuum pumps, instruments that deliver calibrated electrical shocks to the nipples and genitals, and life size inflatable male and female dolls with penetrable and vibrating orifices. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sex-machine」の詳細全文を読む スポンサード リンク
