Atomic Inflatable Superior Plug by Nasstoys

An expandable silicone butt plug that lets you control stretch and fullness in real-time via a hand pump, starting narrow for easy entry and widening gradually to your preferred depth—ideal for first-timers and experienced players alike.

What it does

When you slide this plug inside, the tapered silicone tip glides past your sphincter with minimal resistance, then settles into your rectum with that satisfying fullness only anal penetration provides. Once positioned, the ribbed texture creates micro-sensations against your inner walls. Each pump of the hand bulb expands the plug further, creating a mounting pressure that makes your hole clench and your pelvic floor engage in real-time. Unlike static plugs locked into one size, this inflatable design lets you gradually stretch your ass until it grips exactly how you want—that pressure-filled sensation that builds with each squeeze.

As the plug expands, blood rushes to your prostate and the nerve endings around your sphincter fire constantly. Your arousal builds differently because each pump creates a new sensation of expansion inside you. Prostate Vibes offer a different approach through vibration, but this plug achieves deep prostate stimulation through controlled pressure and stretch instead. When you finally ejaculate with this sex toy buried inside, the fullness transforms your orgasm—your dick pulses harder because your entire pelvic floor stays locked in tension, and your cum shoots with that extra force that only comes from total anal stimulation.

Size and first use

This plug starts narrow, so entry is manageable even if you're new to anal play. Cockringshop specialise in products for men and couples at every experience level, and we recommend going slowly on your first session. Apply water-based lube generously to both the tip and your opening, then position yourself—on your back with knees bent or on all fours—whichever lets you relax your sphincter best. Guide the narrow tip to your asshole and slowly press inward while breathing out. Once the widest part slides past your sphincter and settles inside, you'll feel immediate fullness. Keep the pump within arm's reach. Start with 3–4 pumps, pause for 30 seconds to let your body adjust, then add more air if you want deeper stretch.

How to use it

Start by applying water-based lube generously to both the tapered tip and your ass opening—this smooth insertion sets up everything that follows. Position yourself on your back with knees bent or on all fours depending on what angle lets you relax your sphincter best, then guide the plug's narrow tip to your asshole and slowly press inward while breathing out. Once the widest part of the plug slides past your sphincter and settles inside, you'll feel immediate fullness.

Keep the pump within arm's reach because you're not done—this is where the real sensation begins. Squeeze the pump bulb slowly, adding air in controlled bursts while paying attention to how your ass responds with each expansion. Your prostate will start responding once the plug reaches medium inflation, creating that electric sensation behind your dick that makes pre-cum leak out. After use, deflate using the one-way valve and clean the plug with warm water and a toy cleaner before storing in a cool, dry place.

Feature breakdown

Who it suits

This plug is perfect if you're new to anal play and nervous about size—you control the stretch from start to finish. Experienced players who crave that maximum stuffed sensation will love the ability to pump up to deep fullness. Anyone who wants real-time sensation building rather than a static fixed size will find the inflation mechanism genuinely different from standard plugs. Your prostate will thank you, and the sensation of pressure mounting with each pump is unique to inflatable designs.

Skip this if you prefer a rigid, non-expandable plug or if you want something that requires no setup or adjustment. It's not the right choice if you need hands-free wear for extended periods—the pump needs to stay within reach to adjust sensation. And if you dislike the idea of controlling your own expansion, a fixed-size plug will suit you better.

How it compares

Standard butt plugs come in one fixed size and stay that way—you're locked into whatever stretch you chose when you bought it. This inflatable plug lets you start small and expand as you warm up, adapting to your mood and comfort level in the moment. Slide Easy Prostate Plugs offer a different design focused on prostate contact through shape and positioning rather than inflation. Choosing between them depends on whether you want to control your own expansion in real-time or prefer a fixed shape engineered for prostate pressure.

What you can use it with

Pair this plug with Cock Ring Sets to maintain your erection while the plug stretches your ass—the ring keeps blood in your shaft while the expanding fullness builds prostate sensation, intensifying both sensations simultaneously. Together they create a complete pelvic-floor experience: the ring maintains hardness and sensation in your dick while the inflating plug creates mounting pressure and nerve firing in your rectum and prostate.
