A rainbow kiss is one of the most talked-about — and taboo — acts in the world of hardcore kink and oral sex fetishes. Not for the faint of heart, it involves a sexual partner receiving oral sex during menstruation, followed by kissing after both partners have orally pleasured each other. The result? A messy, colorful, intensely intimate act that blends blood and semen — hence the “rainbow.”
What Happens During a Rainbow Kiss?
The classic rainbow kiss involves two partners:
- One person menstruating, receiving oral sex
- One person ejaculating during oral or other stimulation
After climax, the two kiss — sometimes with fluids exchanged. It’s raw, visceral, and absolutely not everyone’s cup of tea.
For some, it’s a deeply erotic act of closeness and surrender. For others, it’s about power exchange, body worship, or pushing personal boundaries.
Who Enjoys Rainbow Kisses — and Why?
People who enjoy blood play, kink, or taboo acts often find rainbow kisses thrilling. It blends intimacy and bodily fluids in a way that feels deeply primal. It’s also sometimes part of femdom, humiliation, or ritualistic roleplay. Some do it for the intensity; others, for the shock factor.
Is It Safe?
With any act involving bodily fluids, communication and safety come first. Menstrual blood and semen can both carry STIs. Always be tested, use dental dams or protection if needed, and only engage in rainbow kisses with full consent and mutual understanding.
