A consensual BDSM sexual play whereby a person consents to be forced to orgasm despite their attempts to delay or not to orgasm. The person who is to be brought to involuntary orgasm would typically be put in physical restraints to increase the feeling of helplessness, and deprive them of the ability to control the onset and intensity of orgasm.
