Master Series Colossus XXL offers premium medical-grade silicone construction with hypoallergenic properties, featuring waterproof versatility for shower sessions and internal stimulation capabilities. The body-safe coating ensures comfort during extended wear.

Key Features:

Premium body safe silicone construction delivers comfortable anal penetration and stimulation while the tapered design allows gradual insertion for experienced users seeking intense filling sensations during solo or partner play.

Extra large dimensions provide maximum anal stretching and fullness that stimulates nerve endings throughout the rectum and can trigger powerful orgasms through sustained internal pressure and movement.

Flared suction cup base prevents unwanted migration during wear while enabling hands free mounting on smooth surfaces for solo penetration and allows secure retrieval after extended anal play sessions.

Non porous hypoallergenic silicone resists bacteria buildup and conforms to body temperature for comfortable extended wear while the smooth surface reduces friction and enhances pleasurable gliding during insertion.

Versatile design works for power play scenarios including domination and submission while the impressive size creates visual excitement and psychological arousal for both partners during intimate encounters.

What it does

Medical-grade silicone warms to your body temperature and adapts as you relax, creating smooth, consistent contact inside. Warmth enhances sensation, while the non-porous material prevents bacterial growth and stays cleaner than porous materials throughout longer sessions. You can use it for deep internal anal massage or flip your approach and press it against external pressure points for a different type of stimulation.

Waterproof engineering opens up shower play—warm water adds another sensory layer while you explore. Start small and build intensity as your body adjusts, or position it hands-free using the suction cup base against tile, glass, or other smooth surfaces. Novice Prostate Toy Sets offer a good stepping stone if you're still building confidence with anal play.

Specifications

  • Material: Medical-grade silicone with hypoallergenic coating
  • Size: XXL dimensions
  • Waterproof rating: IPX7 (fully waterproof for shower and bath)
  • Base: Suction cup for hands-free positioning
  • Cleaning: Soap and water

Size and first use

XXL means this plug is substantial—it's designed for people who've used smaller plugs and are ready for more filling sensation. Start by applying plenty of lubricant to both the plug and the area you're stimulating. Go slow on your first session, letting your body relax and adjust before pushing deeper. Work up to longer wear times over several sessions rather than jumping straight to extended use. Cockringshop specialise in products for men and couples, so if this size feels too large to start, you might explore smaller options first and build up gradually.

How to use it

Begin with generous lubrication on the plug and your target area. The waterproof design lets you start in the shower with warm water running, which relaxes tissues and warms the silicone at the same time. Angle the plug slowly and press steadily, pausing if you feel tension. Once inserted, you can switch between staying still and gently rocking it to explore different sensations and depths.

Position the suction cup against a smooth, flat surface like a tile wall or glass shower screen to go hands-free and experiment with different angles. Wear it for 10–15 minutes initially, then gradually extend time as comfort increases. After use, rinse thoroughly with soap and warm water, dry fully, and store in a clean, dry place away from direct sunlight.

Feature breakdown

Feature Specification Benefit Experience
Medical-grade silicone Body-safe, non-porous material Eliminates health concerns; stays cleaner Worry-free extended sessions without irritation
Hypoallergenic coating Prevents allergic reactions Safe for sensitive skin Comfortable wear without redness or itching
Waterproof design IPX7 rated, fully submersible Shower and bath play possible Warm water enhances sensation and relaxation

Who it suits

This plug is built for experienced anal users who've graduated from smaller sizes and want something substantial. If you have sensitive skin or previous reactions to sex toys, the medical-grade silicone and hypoallergenic coating make this a safer choice. Couples planning shower play will love the waterproof design and hands-free positioning options. Solo players who like switching between internal and external pressure play find the shape and size perfect for extended exploration.

Skip this if you're brand new to butt plugs—start with a smaller size first. If you prefer firmer, non-flexible materials, silicone's give-and-flex may not suit your needs. Those who dislike waterproof-only designs will be fine here, but if you want vibration or multi-speed options, this is a non-vibrating plug and won't deliver that.

Tested and quality-checked

Every new line we stock is hands-on tested before it ever goes live — we power it up, run it through its functions, and check it for safety and for how it actually performs. Overseas orders get a second function-test right before they ship, so a dead motor never reaches your door. Nothing is used for its intended purpose; it is checked, inspected, and re-boxed. What that means for you is simple: the unit you open is one we already know works. See how we test every product →

How it compares

Silicone plugs like this one flex and warm to your body, creating a softer, more adaptive feel than rigid materials like glass or stainless steel. Slide Easy Prostate Plugs offer a comparable body-safe approach with their own design focus. If you want firmness without any give, steel or glass will feel very different—rigid and unyielding. This plug's XXL size, waterproof rating, and suction cup base make it distinct within the silicone range; choose based on whether you prioritize flexibility, shower use, and hands-free play.

Please read — safety first. Put the ring on before you are fully erect and use plenty of water-based lubricant so it slides on without pinching. Keep wear time short — no more than 20 minutes while you are getting used to it, and never fall asleep wearing one. Take it off straight away if you feel numbness, coldness, a change in colour, or any pain, as these mean blood flow has been cut off too far. Never share between partners without cleaning the item first or using a fresh condom. This information is general in nature only and is not medical or professional advice, and does not take your personal circumstances into account. Stop use and speak with a qualified medical professional if you have a relevant health condition, take medication for erectile function or blood pressure, or notice pain, numbness, or discolouration that does not settle.

What you can use it with

Pair this plug with Cock Ring Sets during partnered or solo sessions. A cock ring maintains erection hardness and blood flow while the plug provides deep internal sensation, creating layered stimulation that builds arousal differently. The combination works especially well during partnered sex or extended masturbation, since the ring supports staying hard while the plug intensifies sensation throughout the session.
