Ejaculating Dildo

What is an Ejaculating Dildo?

A toy equipped with an internal reservoir or tube system that allows the user to release fluid on command, simulating ejaculation during play.

How Does the Mechanism Work?

An ejaculating dildo contains a cumtube -- a narrow channel running through the center of the toy from base to tip, terminating in a small opening at the head. At the base end, the tube connects to either a squeeze bulb or a syringe-style reservoir. The user fills the reservoir with their chosen fluid before play, then squeezes the bulb or depresses the plunger at the desired moment. The fluid travels up through the internal channel and exits through the tip, creating a realistic ejaculation effect. The entire system is sealed within the silicone body, so no external hardware is visible during use.

How Do You Choose the Right Fluid?

The fluid you use matters more than most people realize. Since the toy itself is made from platinum-cure silicone, you need a water-based fluid that will not degrade the material. Dedicated cum lube is the most popular choice -- it is thick, white, and opaque, creating the most convincing visual effect. Standard water-based lubricant also works perfectly well for those who prefer a clear, less viscous option. Never use silicone-based lubricant with a silicone toy, as it will chemically bond to the surface and permanently damage the finish.

After each use, thorough cleaning of the cumtube channel is essential. Most makers include a thin cleaning brush or recommend flushing warm water through the tube several times. Residual fluid left inside the channel can develop mold or bacteria over time, so drying the internal passage completely between sessions is just as important as cleaning the exterior surface.

How Do Fantasy Designs Use Ejaculation?

Ejaculating dildos are especially popular in the fantasy toy community because they add a powerful creature play dimension. A dragon dildo that actually releases fluid elevates roleplay from visual imagination to physical sensation. The same applies to tentacle and alien designs -- the ejaculation mechanic adds a layer of immersion that static toys simply cannot replicate. Some designs feature multiple exit points rather than a single opening, creating a spray pattern unique to the creature theme.

What Is the Difference: Cumtube vs. Pump?

The terms overlap but are not identical. A cumtube toy uses a simple squeeze-and-release mechanism with a flexible bulb. A pump dildo may use a more elaborate pressurized system capable of sustained flow rather than a single burst. Both fall under the ejaculating dildo umbrella, but the delivery experience differs. Cumtube designs tend to be simpler, more affordable, and easier to clean, while pump systems offer more control over flow rate and volume.

Whether you are adding a new dimension to solo play or enhancing partnered roleplay, an ejaculating dildo from LustMonster delivers an experience no static toy can match. The combination of fantasy sculpting and functional fluid delivery creates something truly interactive.
