Atomic Inflatable Advanced Plug by Nasstoys

An expandable silicone butt plug that inflates to your desired fullness using a handheld pump, giving you complete control over stretch and pressure during anal play. Built for people ready to move beyond fixed-size plugs and experience customisable, building sensations.

What it does

This plug fills your backside with a satisfying stretch that builds as you control the pump. Unlike rigid butt plugs that reach one fixed size, the expandable silicone chamber inflates gradually, pushing against your anal walls with increasing pressure. You decide exactly how full and packed you feel at any moment. Every squeeze of the pump creates distinct pulses of sensation as the triple-beaded shaft pushes outward against your walls.

Orgasms arrive differently with inflation play because the ongoing pressure builds rather than plateaus. Your erection hardens as the expanding silicone pushes against your prostate, while your sphincter clenches around the ridged texture, amplifying sensitivity with each involuntary squeeze. Anal Lubricant makes insertion smoother and lets you focus entirely on the sensations of controlled inflation. Climaxes tend to arrive harder and last longer once they hit because the psychological arousal of deliberate fullness compounds the physical pleasure.

Specifications

• Insertion depth: 4 inches with 1.45-inch width at maximum expansion
• Material: Medical-grade silicone body with phthalate-free rubber pump and ABS valve
• Pump: Handheld squeeze pump, 3 inches long, connected by 23-inch cord

• Water resistance: Fully splashproof and submersible for shower or bath play

Size and first use

Starting size is manageable—the tapered tip is designed for smooth entry, and you control how much it expands once inserted. Begin with the pump disconnected, getting comfortable with the plug itself before adding any inflation. Go slowly with your first few pump strokes, letting your sphincter and rectal tissue gradually accommodate the expanding silicone. Most people find the sweet spot around 3–5 pumps, where pressure builds against sensitive nerve endings without becoming uncomfortable. Cockringshop specialise in products for men and couples, so if you're exploring solo or with a partner, take your time finding what feels right for your body.

How to use it

Coat the tapered tip generously with water-based lubricant—the smooth silicone glides easily, but extra slip helps you past your sphincter without strain. Get into a comfortable position (kneeling or on your back with legs up work well), relax your breathing, and press the tapered point against your hole until your sphincter accepts it. Gently push the plug deeper and hold it there, letting your body adjust before you touch the pump. Once you're settled and the wide anchor base sits flush against your backside, start squeezing the pump with slow, deliberate strokes.

Rapid pumping doesn't work as well as steady, controlled pressure—your tissue needs time to gradually accommodate the expanding silicone. Stop when the sensation feels almost too much, then hold it there and let arousal build. After use, deflate fully using the easy valve, then rinse the plug and pump under warm water with mild soap. Store it somewhere cool and dry, away from direct sunlight.

Feature breakdown

Who it suits

This plug works best for people with intermediate anal experience who've worn fixed butt plugs before and want to move beyond single-size play. If you enjoy building sensation gradually and having control over your own fullness, the inflation mechanism will appeal to you. Solo players and couples both appreciate the customisable stretch and the psychological kick of deliberate inflation. Prostate owners will find the expanding pressure particularly rewarding as it builds direct contact with sensitive internal nerves.

Skip this one if you're completely new to anal play—start with a smaller, non-inflatable plug first to build your comfort level. If you prefer rigid, fixed-size plugs or you find inflation play uncomfortable, a traditional butt plug will suit you better. People with very sensitive anal tissue should also begin with something smaller and gentler before moving to an expandable design.

How it compares

Fixed-size butt plugs reach one set diameter and stay there—they offer consistent, reliable pressure but no variation. Inflatable plugs like this one let you start smaller and gradually expand, building sensation as your body opens and your arousal grows. Slide Easy Prostate Plugs offer targeted internal contact without the inflation mechanism. Choose inflation if you want control over intensity throughout play; choose fixed-size if you prefer simplicity; choose prostate-specific if you want direct nerve targeting without expansion.

What you can use it with

Pair this plug with Cock Ring Sets to intensify erection and prolong arousal during inflation play. A ring maintains hardness while the expanding plug pushes against your prostate, creating a feedback loop of sensation that compounds pleasure. The combination of ring support and internal pressure often produces longer, more intense orgasms than either alone.
