The BDStyle Locking Chastity Control Anal Plug transforms ordinary backdoor play into inescapable control scenarios with expandable steel that locks at your chosen diameter. Starting at 4.1cm closed and expanding to 7cm, this stainless steel and aluminum construction brings genuine chastity play devices functionality to anal training. The manual expansion mechanism with locking pin means once it's set, removal requires the key—creating psychological intensity alongside physical stretch. At 10.2cm insertable length, it provides substantial presence before you even begin expanding. The removable rubber cuff protects skin from pinching while the metal components handle temperature play that softer materials simply cannot deliver.
This plug suits advanced anal enthusiasts and power exchange couples ready for genuine control elements in their play. The expandable feature appeals to those serious about progressive stretch training who want measurable results. Dominant partners seeking enforced compliance will appreciate the locking mechanism's psychological impact. Solo users exploring self-discipline through chastity devices find this creates accountability that standard plugs lack. Given the 4.1cm starting diameter, you need prior experience—this isn't a beginner's first plug by any measure.
The combination of expansion, locking mechanism, and medical-grade metals creates functionality beyond standard plugs. Here's what sets it apart:
Begin with extensive warm-up using progressively larger toys before attempting insertion at the closed 4.1cm diameter. Insert fully at minimum size, then expand gradually—one or two clicks at a time—allowing your body to adjust between increments. Use the locking mechanism only after confirming comfortable positioning and manageable stretch. For chastity scenarios, the keyholder controls removal timing, creating enforced wear periods. Temperature play works best before insertion rather than during—run under water to heat or cool the metal, then insert while the temperature contrast remains intense.
Disassemble the rubber cuff and wash all components separately with antibacterial toy cleaner after each session. The metal parts tolerate boiling for sterilization, though the rubber cuff requires gentler cleaning. Dry thoroughly before reassembling to prevent water spots or corrosion in the locking mechanism. Lubricate the expansion mechanism occasionally with a drop of water-based lubricant to maintain smooth operation. Store in the provided case or wrapped separately to protect the polished finish from scratches. Inspect the locking pin regularly for wear or damage that might compromise security.
Other shoppers also liked items from the anal lube section, particularly thicker formulas that stay effective during extended metal toy wear.
Stainless steel and aluminum construction provides medical-grade safety with substantial heft that announces its presence. These metals are completely non-porous, hypoallergenic, and compatible with all lubricant types. The expansion mechanism shows precision engineering with smooth ratcheting that locks securely without slippage. The rubber cuff uses body-safe material that remains flexible across temperature ranges. Weight distribution feels balanced despite the heavy materials, preventing uncomfortable tilting during wear. The locking mechanism uses durable components that withstand repeated securing without degradation.
Insertable length of 10.2cm (4 inches) provides adequate depth without excessive reach for most users. Starting diameter of 4.1cm already demands experience—those comfortable at 3.5cm will find this manageable, but smaller users need intermediate sizing first. Maximum expansion to 7cm represents extreme territory that requires extensive training and patience. The flared base prevents over-insertion regardless of expansion state. Plan on taking weeks or months to reach maximum diameter safely rather than forcing progression. Each expansion click adds approximately 3-4mm of girth.
Metal's unyielding nature creates constant pressure awareness that flexible materials cannot match. The substantial weight provides gravitational reminders during movement or position changes. Initial insertion at 4.1cm feels firm and full before any expansion begins. Each expansion click brings acute stretching sensation followed by your body's gradual accommodation. The locking mechanism adds psychological intensity—knowing removal requires permission changes the entire experience. Temperature play creates sharp initial contrast that fades as the metal warms. Extended wear at expanded sizes demands mental endurance alongside physical tolerance.
This plug pairs intensely with cock cages for comprehensive genital and anal control during extended chastity sessions. Combine it with bondage restraints to prevent the wearer from attempting unauthorized removal. For those building complete control scenarios, adding this to existing chastity devices creates layered denial that affects both front and back simultaneously. The expandable nature works beautifully alongside training protocols where the dominant gradually increases diameter requirements over weeks or months.

I've tested dozens of anal toys, but this one demanded respect from the first moment I held its weight. The 4.1cm starting diameter required serious warm-up—I used two progressively larger plugs over fifteen minutes before attempting insertion. Once in, the expansion mechanism worked smoothly but intensely. I managed three clicks beyond initial insertion before needing to pause and breathe through the stretch. The psychological element surprised me: knowing I couldn't remove it without the key added genuine submission that standard plugs never achieve. I wore it for forty-five minutes at moderate expansion, and the metal's weight created constant awareness that ranged from pleasantly full to intensely present depending on movement. Standing and walking emphasized the heft; sitting required careful positioning. Temperature play before insertion exceeded expectations—cold water for two minutes created startling contrast that lasted through insertion. The rubber cuff proved essential; without it, I'd worry about pinching during expansion. The locking mechanism held absolutely secure with zero slippage. My limit was approximately 5.5cm expansion; the full 7cm will take months of dedicated training. For advanced players ready for genuine chastity enforcement and measured stretch progression, this delivers uncompromising quality. Just respect its capabilities and progress slowly.
Standard anal plugs lack both expansion capability and locking security. Inflatable plugs expand but offer no locking mechanism and use softer materials that compress under body pressure. This combines mechanical expansion precision with metal's rigid firmness and actual security features. The incremental control beats inflation's vague sizing. For serious chastity enforcement or structured training programs, this provides accountability and measurement that no alternative matches. The temperature play bonus separates it from plastic or silicone expanders completely.
