What you're getting

Master Series Trillium Steel Locking Anal Plug by BDStyle is a precision-engineered steel butt plug designed for bondage control and intense anal play. The bulb starts at 4 centimetres wide when inserted, then unfurls into five distinct petals that expand to 5.8 centimetres at the press of a button on the base. Steel construction means the plug feels smooth during insertion, conducts temperature for extra sensation and maintains its shape through extended wear. Unlike standard butt plugs, this one transforms from comfortable to intensely full in seconds.

The padlock mechanism is where control happens. Once locked, removal becomes impossible without the keyholder's permission, creating a powerful dynamic in power exchange relationships. A removable rubber ring lets you choose between classic plug sensation and full expansion capability. Steel resists staining and odour absorption, making cleaning straightforward and long-term storage worry-free.

What stands out

  • Expandable petals: The five-petal system transforms from comfortable to intensely full at the press of a button, creating sensations unique to this design.
  • Complete locking control: The padlock mechanism ensures the wearer cannot remove the plug without the keyholder's explicit permission.
  • Temperature play: Steel conducts temperature, starting cool and warming to body heat, adding another dimension to sensation during wear.
  • Removable ring system: Switch between traditional plug sensation and full expansion capability without changing the entire device.
  • Durable construction: Steel resists discolouration, odour and degradation, meaning this plug maintains its condition through years of use and cleaning.

Specifications

  • Material: High-quality steel, body-safe and non-porous.
  • Total length: 14 centimetres; insertable length 10.9 centimetres.
  • Unexpanded width: 4 centimetres; expanded width 5.8 centimetres across the widest petal.
  • Base diameter: made to sit comfortably against the body with space for the padlock loop.
  • Weight: Steel construction makes this a substantial, weighted toy.
  • Closure: Padlock mechanism with keyed lock; padlock included.
  • Removable component: Rubber retention ring can be removed to enable petal expansion.
  • Box contents: Plug, padlock, keys, rubber ring and care instructions.

Preparation, use and clean-up

Before insertion, apply generous amounts of anal lubricant to both the plug and your opening. Start with the rubber ring in place to maintain the traditional 4-centimetre width during insertion. Relax and allow the smooth steel to slide in slowly; do not rush. Once fully inserted, you can either leave the ring in place for classic sensation or remove it to prepare for expansion.

When you want to activate the petals, remove the rubber ring and press the outer steel disc at the base. The petals will unfurl inside, creating intense fullness and pressure. Once locked with the padlock, the device cannot be removed until the keyholder uses the key. To remove, opens up the padlock, allow the petals to retract by pressing the base button again, then ease the plug out slowly. Rinse thoroughly with warm water and soap, paying particular attention to the petal mechanism and Anal Dilators can help prepare the opening for easier insertion before using this product.

Is this the one for you?

This plug suits experienced players seeking control and intense sensation through bondage.

Great if you…
  • Practise power exchange and want your partner to have complete control over your release.
  • Crave intense fullness sensations beyond what standard plugs provide.
  • Enjoy the psychological intensity of being locked in place and unable to remove the device.
  • Want a steel toy that responds to temperature and maintains its condition through extended wear.
Maybe not if you…
  • Are new to anal play; the expanded width may feel too intense without proper warm-up and experience.
  • Prefer soft, flexible materials; steel is rigid and does not compress during wear.
  • Need a toy that removes quickly; the locking mechanism makes spontaneous removal impossible.
Always use generous amounts of lubricant before insertion, warm up gradually with smaller toys first, and never attempt to remove this plug without first unlocking it and allowing the petals to retract fully. Safety first. Use only toys with a flared base or retrieval cord — anything without one can be drawn inside and require medical removal. Go slowly, use plenty of lubricant, and seek medical advice for bleeding or lasting pain. This information is general in nature only and is not medical or professional advice; it does not account for your individual circumstances. Stop use and seek medical advice if you experience pain, numbness, swelling, discolouration, bleeding or persistent irritation.

Care and storage

Wash the plug thoroughly under warm running water with mild soap, ensuring you clean every petal groove and the base mechanism. Dry completely with a soft cloth before storing, since any trapped moisture can encourage rust. Store in a cool, dry place away from other magnets or ferrous metals. Keep the padlock and keys in a safe place. The steel will naturally develop a patina over time; this is normal and does not affect function or safety.

What to expect

by Risetob

The smooth steel slides in comfortably during initial insertion, especially if you have used anal toys before. Once fully seated, the weight of the steel becomes noticeable; this sensation of fullness is intentional. Most first-time users find the initial 4-centimetre width manageable, then experience surprise at how different the expanded sensation feels when the petals unfurl.

The moment those petals expand creates an intensity that catches many users off-guard—it is a deliberate jump in fullness and pressure. This is by design and why warm-up matters. Relaxation is essential; rushing or tensing against the expansion will create discomfort. The psychological shift when you hear the padlock click is profound for many players; the knowledge that removal is now impossible creates a headspace distinct from standard toy use.

Cleaning requires attention to the petal mechanism but is straightforward with warm water and soap. Steel resists staining and odour absorption, so upkeep is minimal. Most users report the device holds its condition excellently through regular use and proper care.
