CEI, short for Cum Eating Instruction, is a BDSM activity in which an individual, usually a submissive man, is told to consume his own semen. CEI usually takes place under the instruction of a female dominant during activities like jerk-off instruction (JOI), though, as with all fetishes, rigid rule structures don’t always hold.
FemDom: What is It, What Does it Mean?
Female dominance, also known as femdom, is the term for a BDSM relationship or scene in which a female is the dominant or top partner. This dominant female may go by any one of several names to her submissive, including Mistress, Domme, Madame, or Dominatrix. Femdoms often engage in BDSM activities with their subs, including rough play, bondage, JOI, forced orgasm, forced feminization, forced chastity, humiliation, pegging, and cum eating instruction.
CEI: How Does it Work?
Generally, cum eating instruction works in one of two ways: either the sub knows ahead of time that his Domme will require him to eat his own semen after he ejaculates, or she will inform him after he comes that she wants him to consume it. Some submissives prefer one version over the other, but it isn’t uncommon for subs to enjoy both types equally.
Being told he will need to eat his own ejaculate often presents a submissive with an intense set of erotic and conflicting desires. They may very much want release, but not to have to consume their own come. The thrill of orgasm is only heightened for them from the apprehension and humiliation from knowing what’s coming next.
Likewise, having a mistress that tells the submissive only after a session of jerk-off instruction that he is now required to consume his own ejaculate can pose its own thrill, as the submissive may never know whether or not it will be required. Many dominatrixes choose to vary how regularly they require their subs to consume their own semen, tease about it, and otherwise attempt to catch their charges off guard. Additionally, while the eating is usually done instantly, it may also be stretched out over time, with the sub being required to mix it into their food or drink and consumed over the course of the day.
As a concept, cum eating is a fetish that should be arranged and discussed between a mistress and sub before engaging in any scenes or beginning a relationship. As with any major BDSM activity or play, the person on the receiving end needs to decide if it is something they are willing to participate in long before anything physical actually occurs. CEI is not something that should be brought into the picture without previous instruction or discussion, especially because it has the potential to ruin the BDSM and sexual experience altogether for someone who has no interest in it. In other words, a mistress should only instruct a submissive to eat their own cum if that person has a genuine desire for that experience.
