Cum eating
Cum eating is the erotic act of consuming semen — one's own or a partner's — swallowing it or savoring it in the mouth as the charged finish to a sexual act. Once treated as strict taboo, it's now a common and accepted part of many people's play, though a man eating his own semen (often on a dominant's command) still carries an extra transgressive charge. It appears across all pairings and orientations. The appeal blends intimacy, submission, and the thrill of crossing a personal boundary. It overlaps with cum play, felching, and cum fetish.
For many the draw is intimacy and acceptance — taking in a partner's most personal fluid can feel like a complete, unreserved act. In a D/s frame it's potent submission, especially self-eating on command, and for some the pure taboo of it is the turn-on.
A partner takes semen into the mouth and swallows or plays with it — after oral sex, from the body, or scooped up — sometimes shared mouth-to-mouth (snowballing) or eaten on a dominant's instruction. It's often the deliberate climax of a scene.
Semen can transmit STIs, so swallowing is safest with tested, trusting partners or avoided with barriers otherwise. It's harmless to swallow in itself (rare allergies aside). Keep it consensual — no one should be pressured into it.
