A fucking machine is a mechanical sex toy that simulates penetrative sex. Simple in concept, fucking machines are motorized devices that feature an extended arm to which the user can attach a dildo, vibrator, or butt plug. The motor powers the arm in a repetitive motion much like intercourse. Different types and models offer different features, such as speed, vibration, intensity and power of pumping motion. Some fucking machines will also allow the attachment of penis sleeves for simulated stroking.
Fucking machines can be used for a variety of types of penetration including vaginal, anal, and oral. Because many different people can enjoy penetrative sex, fucking machines are not exclusive for use by folks of any specific gender or sexuality. Depending on the quality of the product, sex machines can be positioned in unique ways to offer different angles of penetration in a variety of sex positions. Basic versions may only propel in one horizontal or vertical angle while other advanced models feature adjustable thrusters that are more versatile.
Fucking machines offer the opportunity for consistent, repeated thrusting—a challenging act to achieve in solo sex. Users can position the fucking machine and themselves into an optimal position to specifically stimulate the G-spot or prostate. Many models offer remote controls so that users can find their best position and then stay there without having to make adjustments to the machine. This can also increase the potential of hands-free masturbation orgasm.
Primarily presented as a masturbation tool, fucking machines can also be used in partnered sex. For those who have a desire for double penetration but do not want to introduce a third person into a relationship, fucking machines can be the replacement. Fucking machines are also popular in the BDSM community. Combined with bondage, they are used in forced orgasm and humiliation scenes.
Fucking machines are also called sex machines.
