Masturbation of another person
Masturbation of another person is the act of manually stimulating the erogenous zones, especially the genitals, of that person so as to cause them to experience sexual arousal and/or orgasm. It can be done either with or against their will (or pretended will), and also mutually.
If the masturbation is done by hand, it is called a handjob or fingering. It can also be done with the help of sex toys such as dildos, vibrators, artificial vaginas, and can also be combined with manual anal stimulation (prostate massage), with anal toys or with pegging.
When masturbation is done using one's feet, it is called a footjob (in Japanese, ashikoki). If it is done with the mouth, it is generally not called masturbation but oral sex or blowjob (in the case of fellatio), although the activity and result can be similar.
Masturbation of another person is sometimes called a form of non-penetrative sex, although this is not necessarily the case as penetration of the vagina and/or anus with the fingers or with a sex toy can be involved. Masturbation of the anus is known as anal masturbation.
When the masturbation is mutual, it is called fingering or heavy petting. When body parts other than the hand, feet or mouth are used (such as genital-to-genital rubbing without penetration), it is called frottage.
Nonconsensual (forced) masturbationEdit
When the masturbation is nonconsensual, or when nonconsensuality is "played" in BDSM, or in fiction, it is called forced orgasm. The subject is often restrained for this, with at least their hands restrained so they can not intervene. Often their feet are also restrained with spread legs to provide better access to the genital area. There is a wide variety of possible positions: standing, lying, kneeling, on all fours, etc.
If the subject is male, bringing them to forced orgasm is also called milking. In the case of females, the phrase "made to squirt" is often used, and for both sexes, the phrase "made to cum" is popular. The term 'forced masturbation' is generally avoided because it can also be (mis)understood to mean "forced to masturbate oneself" (which is another form of play found in BDSM).
In a kind of play known as tie and tease, the partner is bound and then teased repeatedly to the point of orgasm but denying, or stopping short of allowing them to orgasm, a method also known as orgasm control.
Besides the sexual pleasures involved in giving and experiencing an orgasm, people into BDSM find the idea erotic that the passive partner is brought to arousal, and further brought to orgasm without their control. As soon as they are restrained and in the hands of a skilled partner who has set their mind on this kind of play, they have no control over whether, when, or by what means they will be "made to come".
Sometimes, mainly in BDSM drawings and videos, instead of manual stimulation, sex machines (for females) or milking machines (for males) are used.
Forced orgasm and spankingEdit
In BDSM play, art, stories and videos, masturbation and spanking of a person is sometimes combined. Examples of spanking artists who drew such combinations are Franco, Julie Delcourt and Kami Tora. Franco also drew complex fictional "combined spanking and milking machines".
