Rear Assets Trainer Kit by NS Novelties

Anal training requires patience, safety, and the right progression. Shine Bright with Rear Assets Trainer Kit - Multicolour Rainbow Gem Edition delivers three graduated aluminum plugs designed for comfortable, controlled exploration at your own pace.

What it is

Shine Bright with Rear Assets Trainer Kit - Multicolour Rainbow Gem Edition is a three-piece anal training system built from aircraft-grade aluminum. Each plug is precisely sized to allow gradual progression, with the smallest at 6.9 cm and the largest at 9.5 cm. The smooth aluminum surface is body-safe, temperature-responsive, and easy to clean. Flared bases on all three pieces prevent accidental slipping, making safety a built-in feature rather than an afterthought.

What sets this kit apart is its combination of functional design and visual appeal. The rainbow gem accents transform a training tool into something genuinely beautiful to look at and hold. The aluminum's ability to retain temperature creates additional sensory possibilities—warming or cooling the plugs before use adds another layer to your exploration.

How to use a butt plug

Start with the smallest plug and apply generous water-based lubricant to both the plug and your anus. Relax your muscles and gently insert the plug, moving slowly and pausing if you feel tension. Once comfortable, you can leave it in place or gently move it in and out. Duration depends on your comfort level—begin with short periods and gradually extend your time as you build confidence.

Progress to the medium plug only after you're fully comfortable with the small one. Repeat the process with extra lubricant and patience. The large plug represents the final step in your training progression. For variety, try temperature play by running the aluminum under warm or cool water before use. Explore the Butt Tails collection if you want to add visual appeal once you've mastered training with plugs.

Care and storage

Wash each plug thoroughly with warm water and mild soap immediately after use. Dry completely with a soft cloth before storing. Keep the kit in its discrete packaging to protect the aluminum and gems from dust and damage. Avoid harsh chemicals, abrasive scrubbers, or extreme temperature changes that could harm the surface. Store in a cool, dry place away from direct sunlight.

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 →

This kit excels for controlled progression with submissives new to anal training. The graduated sizes let me manage their expansion precisely, watching their reactions deepen as they move through each stage. Rainbow gems create a visual anchor for their submission—a sparkling reminder of the boundaries they're expanding under my direction. Aluminum's temperature responsiveness becomes a psychological tool; warming and cooling between plugs keeps them uncertain and heightens their sensory awareness.

My most effective sessions combine this kit with sensory deprivation. Blindfolding a submissive while introducing each plug forces them to rely entirely on physical sensation and my guidance. The smooth metal gives me complete control over pace and depth. I monitor their breathing and muscle tension carefully, adjusting my approach based on real-time feedback. Patience yields the best results—rushing defeats the purpose of training.

Different submissives require different strategies. Some respond to gentle, methodical progression; others need firmer direction and faster advancement. This kit's three-size structure gives me flexibility to customize each training session. The flared bases eliminate anxiety about safety, letting both of us focus entirely on the psychological and physical elements of the scene. Consistency matters more than intensity when building genuine anal capacity and control.
