forced partners
Two or more partners are forced or coerced into performing intimate acts with one another. These acts are often sexual or fetishistic, but don't have to be. For example, forced kissing, touching, or even a forced relationship could be considered forced partners.
None of the partners engaged in the act are in control of the situation. Either a third party is in control, or the situation arose from pure circumstance. The third party need not be present in the image, nor the circumstance explained, so long as it's clear that the subjects of the tag have been forcibly partnered with each other.
Use cases include but are not limited to a mistress/master forcing slaves to have sex for viewing pleasure; coaching a straight boyfriend in taking/sucking dick; holding down or restraining a character to be fucked by an eager dom; and using mind control to make a character be intimate with someone other than the mind controller.
