The Master Series Nova is a vibrating prostate massager and a cock and ball ring in one silicone piece. A stretchy ring wraps around the shaft and balls, while a curved plug angles inward to press on the prostate, and the two pull against each other with every move. It's made for experienced anal players who already enjoy prostate play and cock rings and want to wear both at once, solo or during sex.

Two toys joined in one piece

The ring and the plug are moulded together in a single piece of silicone, joined to each other. The ring goes around the shaft and testicles at the same time, and the curved plug sits behind it, inside the body. Because the two are linked, every movement of your hips, every thrust and every tightening of the pelvic muscles tugs on one end and shifts the other. That's what makes the Nova different from wearing a separate plug and ring: the parts work against each other, so you feel pressure inside and a pull outside together. The plug is angled to reach in toward the prostate, with a rounded bulb at the end.

Getting the fit right

The ring measures 1.5 inches (3.8 cm) across and stretches. That's a snug size, since it has to fit around everything at once, so it suits people who already know they like a firm cock and ball ring. Put the ring on first while you're soft. Lube it lightly, slip one testicle through, then the other, then fold the shaft through last. Next, lube the plug well and guide it in slowly, letting the join between plug and ring sit flat along the perineum. If the ring feels too tight, or the plug pulls uncomfortably, this toy may not suit your build, and a separate prostate plug will be easier.

How this vibrating prostate massager feels

The Nova runs on one AAA battery, which isn't included, so pick one up before your first session. The vibration sits in the plug, which means you feel it deep inside rather than on the surface. Try it switched off first to get used to the fit, then turn the vibration on once you're settled. Many people find prostate sensation builds slowly; give it time instead of reaching for more intensity straight away. Take the battery out when you put it away for a while, so it can't leak into the housing.

Lube, cleaning and care

Use water-based lube only, as Master Series specifies. Silicone lube can break down the surface of silicone toys. For cleaning, warm soapy water or a toy cleaner is enough after most sessions. The maker also says the silicone can be sanitized in boiling water, wiped with a bleach solution or run through the top rack of a dishwasher on low heat. Remove the battery and check what the motor housing can take before you try any of those. Dry it fully and store it away from other silicone toys.

Helpful Information

Frequently Asked Questions

Helpful answers about Master Series Nova Vibrating Prostate Massager & Silicone C&B Ring.

What does a cock ring do on a prostate toy like the Master Series Nova?

On the Master Series Nova the ring does two jobs. It holds the plug in position, and it adds a snug squeeze around the shaft and testicles. Because ring and plug are joined, movement makes the ring tug and the plug shift, so the sensations feed into each other.

Is the Master Series Nova good for a first prostate massager?

Usually not. Master Series aims the Nova at adventurous anal players, and the fixed link between ring and plug leaves little room to adjust. If you're new to prostate play, start with a standalone plug or massager, then try the Nova once you know what angle and pressure you like.

How long can I wear the Master Series Nova?

Keep the ring on for 20 to 30 minutes at most, and take it off straight away if your skin feels cold, numb or painful or changes colour. The plug can be uncomfortable for long periods too. Remove the plug first, then roll the ring off gently.

Can I use the Master Series Nova during sex?

Yes. The Nova is made to be worn during penetrative or oral sex as well as solo. The plug stays inside while the ring sits at the base, so it works in most positions. Check in with yourself often, since arousal can make the ring feel tighter as you go.

What battery does the Master Series Nova need?

The Master Series Nova takes one AAA battery, not included. Use a fresh alkaline or rechargeable AAA, make sure the battery cover is closed fully before use, and take the battery out before deep cleaning so no moisture reaches the contacts.

Can I use silicone lube with the Master Series Nova?

No. Master Series says the Nova is compatible with water-based lube only, because silicone lube can damage silicone toys over time. Choose a thicker water-based gel for the plug and a thin layer on the ring, and reapply if the glide fades.

Will the Master Series Nova ring fit me?

The Nova's ring is 1.5 inches across and stretchy, which is on the snug side for a ring that goes around shaft and balls together. If standard 1.5-inch cock rings already feel tight on you, this one will too. Our cock ring sizes guide explains how to measure.

Can I boil the Master Series Nova?

Master Series says the Nova's silicone can be boiled, wiped with a bleach solution or washed on a low-heat top rack. Because it has a battery-powered motor, take the battery out and keep the compartment dry. For everyday cleaning, warm soapy water is enough.
