The Sentinel – Anal Depth Training Dildo

The Sentinel is a heavily textured anal depth training dildo built for users who genuinely enjoy strong surface detail. Designed for structured anal progression, it combines extended insertable length with pronounced texture to create a deep, intense training experience.

Available in three sizes, The Sentinel supports gradual depth development while delivering consistent tactile stimulation along the entire shaft. The tapered tip allows controlled entry, while the expanding, textured body increases stretch and sensation as depth builds. The wide flared base ensures safe external positioning during use.

This is a serious depth trainer for those who crave length, pressure, and texture working together.

MATERIALS, SAFETY & CARE

Materials

  • Made from 100% high-grade platinum-cured silicone
  • Coloured using body-safe, non-toxic pigments
  • Free from phthalates, latex, BPA and plasticisers
  • Non-porous, hypoallergenic and designed for long-term use

Platinum-cured silicone is considered the gold standard for body-safe sex toys due to its durability, flexibility and resistance to bacteria.

Body Safety

  • Fully non-porous — will not harbour bacteria when cleaned properly
  • Safe for external and internal use
  • Compatible with water-based lubricants only

⚠ Do not use with silicone-based lubricants, as they may damage the surface.

Allergies & Sensitivities

  • Suitable for most people with sensitive skin
  • If you have known sensitivities, we recommend performing a patch test before extended use

Cleaning & Care

  • Wash before and after each use with:
    • Warm water and mild, unscented soap, or
    • A dedicated toy cleaner
  • Allow to air-dry completely before storing
  • For deeper cleaning, toys without electronics may be boiled for 3–5 minutes (if size and design allow)

Storage

  • Store in a clean, dry place away from direct sunlight
  • Keep separate from other silicone toys to prevent surface interaction
  • Use a fabric pouch or original packaging where possible
LORE

The Sentinel is not born. It is engineered in the black between stars, a biomechanical tentacled creature forged in silence, shaped by chaos. Inspired by forms that blur flesh and machine, it drifts through deep space not hunting for sustenance, but for domination. It does not crave survival. It craves control.

When The Sentinel finds a worthy subject, it does not hesitate. Its textured tendrils probe with cold precision, searching not for weakness, but for resilience. Each ridge, each biomechanical contour tests endurance. It decides quickly. You are either discarded… or claimed.

Those it keeps do not escape. The Sentinel enslaves through presence alone, binding body and will into its orbit. To be chosen is to belong. To belong is to be used.

FAQ

Product-Specific FAQs

Is The Sentinel safe for anal use?
Yes. It has a wide flared base designed specifically for safe anal play.

Is this suitable for beginners?
This design is best suited to users with some anal experience, especially those seeking depth training and strong texture.

Can I thrust with it?
It is designed for controlled depth progression rather than fast thrusting. Slow insertion is recommended.

How do I progress between sizes?
Move up only when your current size feels fully comfortable at maximum depth without strain.

What lubricant should I use?
Water-based lubricant only.

Is it body-safe?
Yes. It is made from platinum-cured silicone and is fully non-porous.

Why are there small variations between pieces?
Each toy is handmade from body-safe silicone, making every piece unique. Small variations are a natural part of the process and never affect safety or use. Any item that doesn’t meet our strict quality standards is remade before leaving our workshop. Handmade means character—not compromise.
