Atomic Inflatable Intermediate Anal Plug By Nasstoys

Progressing beyond beginner anal play means wanting more control and customization—but fixed-size plugs limit your options. The Nasstoys Atomic Inflatable Intermediate Anal Plug solves this with a manual pump that lets you expand to exactly your comfort level.

What it is

The Nasstoys Atomic Inflatable Intermediate Anal Plug is an expandable butt plug designed specifically for those moving into intermediate anal play. Its body-safe silicone construction with phthalates-free formulation prioritizes safety during extended wear. The integrated squeeze pump gives you real-time control over how much the plug expands inside you, starting deflated and gradually inflating to your preferred fullness. Ribbed texturing on the entry stimulates during insertion and removal, while the flexible silicone body adapts to your movement and anatomy. An easy deflate valve ensures quick, comfortable removal when you're ready.

What sets this plug apart is the balance between control and sensation. You're not locked into a fixed size—you decide how full you want to feel, and you can adjust mid-session. The 23-inch pump cord stays in your hand or your partner's, making inflation an active part of the experience rather than a one-time setup.

How to use a butt plug

Apply generous water-based lubricant to the ribbed entry and your anal opening. Insert the deflated plug slowly, allowing your sphincter to adjust to the shape. Once fully inserted, squeeze the pump gradually to inflate. Start with minimal pressure and pause between squeezes to assess sensation and comfort. You control fullness entirely through how much you pump. When finished, press the easy deflate valve to release air completely, then remove slowly. Clean immediately with toy cleaner or mild soap and warm water.

For partnered anal play, your partner can control the pump while you focus on sensation and communication. Begin with light inflation during foreplay, then adjust as arousal builds. Many people combine this plug with simultaneous vaginal or penile stimulation for intensified sensations. Experiment with different inflation levels to discover what works best for your body.

Care and storage

Wash the silicone plug immediately after use with toy cleaner or mild antibacterial soap under warm running water. Dry thoroughly with a soft cloth before storage. Wipe the pump and cord with a damp cloth only—they don't require internal cleaning. Store in a cool, dry location away from direct sunlight and heat sources. Use only water-based lubricants to prevent silicone degradation. Never use silicone-based or oil-based lubes.

Mistress Athena's training notes

By Mistress Athena — professional dominant and kink educator, sole instructor behind BDSM Australia's library of training videos. Read her full bio →

The Nasstoys Atomic Inflatable Intermediate Anal Plug is essential in my dominance practice because it gives me precise control over a submissive's anal experience. I start them with minimal inflation and watch their breathing shift as I pump deeper, observing exactly when they reach their limit. The psychological power of controlling their fullness through my hand movements makes them completely dependent on my decisions. I've developed techniques where I inflate gradually while fucking their pussy or mouth, creating overwhelming sensations that break down their resistance beautifully.

What I love most is the feedback the ribbed texture provides. I monitor their physical responses through constant stimulation during insertion, wearing, and removal. The easy deflate valve becomes a tool of control—my submissives know I decide when they get relief, creating intense anticipation throughout scenes. I use this plug during extended submission sessions, sometimes leaving it partially inflated for hours while my subs perform tasks, keeping them acutely aware of their anal penetration and my authority.

Advanced techniques with this plug produce extraordinary results in my training protocols. I combine it with cock rings on male submissives, inflating their ass while the ring restricts their cock, creating unbearable pressure that makes them completely malleable. I use it during extended bondage where I inflate periodically throughout restraint, keeping them in constant anticipatory anxiety. The gradual inflation process triggers deeper submission responses than instant penetration—the slow expansion seems to bypass mental resistance and access primal obedience.

I've trained submissives to request inflation as part of their service protocol, making them verbally acknowledge their desire for anal fullness, which deepens their psychological submission significantly. The 23-inch pump cord allows me to maintain control throughout scenes, keeping it in my hand so they remain constantly aware of my dominance. I use this plug in group scenes with multiple submissives, inflating each to different levels based on their experience and my assessment of their limits.
