Rear Assets Trainer Kit - Multicolour Rainbow Heart Edition enhances anal exploration into a vibrant progression through three chrome-plated aluminum plugs with heart-shaped bases, building from beginner-friendly 4.5cm to experienced 7.6cm lengths while temperature-responsive metal construction adds thermal stimulation possibilities.

Key Features:

Three progressively sized butt plugs provide gradual anal training from beginner to advanced levels allowing comfortable exploration and expansion of anal play capabilities through systematic size progression.

Chrome plated aluminum construction delivers substantial weight and temperature play options while the vibrant rainbow colors create visually exciting stimulation during solo or partner anal penetration sessions.

Heart shaped flared bases ensure safe anal insertion and retrieval while providing comfortable external pressure against the anus during extended wear for hands free anal stimulation experiences.

Waterproof design enables shower and bath anal play while the smooth non porous surface facilitates easy cleaning and maintains hygiene between anal penetration and stimulation sessions.

Progressive sizing from 4.5cm to 7.6cm insertable length trains the anal sphincter for larger insertions while delivering increasing sensations of fullness and anal wall stimulation.

What it does

Each plug in this set targets different depths and stretch levels through careful sizing. Start with the small 4.5cm plug for gentle pressure against your anal opening and initial sphincter response. Progress to the medium 6.1cm to reach deeper nerve clusters and build intensity. Finally, the large 7.6cm plug delivers complete fullness, pressing against your prostate while its weight shifts with every movement you make.

Chrome-plated aluminum conducts temperature rapidly, so you can run each plug under warm water for a luxurious glide or chill it in the fridge for sharp contrast that heightens sensitivity. Glass Prostate Toys offer a different material option if you prefer non-metal construction. Smooth metal surfaces glide effortlessly when properly lubricated, and the flared heart-shaped bases sit flush against your body, keeping everything safe and adding romantic visual appeal to your progression sessions.

Size and first use

Start with the small plug—it's designed as a genuine beginner's introduction, not a trial that feels too intense. Clean thoroughly, apply generous lubrication to both yourself and the plug, then relax your anal muscles with external massage before slowly inserting the tapered tip. Wear it for 10–15 minutes initially to let your body adjust to the weight and sensation. Move to the medium size only when the small one feels completely comfortable. Cockringshop specialises in products for men and couples exploring anal play, and this graduated approach builds genuine confidence without pressure or pain.

How to use it

Begin with thorough cleaning and plenty of lubrication on both yourself and the smallest plug. Use external massage around your anus to relax the muscles, then slowly insert the tapered tip while breathing deeply. Continue until the heart-shaped base sits flush against your body. Your anal sphincter will relax as you breathe; never force insertion or rush the process.

For temperature play, run plugs under warm water or chill them in the refrigerator for 10 minutes before use. Always test temperature on your wrist first to avoid burns or cold shock. Clean the plug after each session with warm water and mild soap, dry it thoroughly, and store it in a cool, dry place. Larger sizes require more preparation time and additional lubrication before you begin.

Who it suits

This kit works brilliantly for anal play enthusiasts at any experience level, from complete beginners nervous about their first plug to advanced users wanting variety in their collection. Couples exploring anal play together will appreciate the visual appeal, the confidence-building progression, and the fact that one kit serves both partners' learning curves. Graduated sizing means you're not buying three separate plugs—you're buying a complete training system that grows with you.

Avoid this kit if you have hemorrhoids, anal fissures, or recent anal surgery. Firm metal construction requires careful preparation and isn't designed for rough or rapid play. If you have temperature sensitivity, use the plugs at body temperature only and skip the heating and chilling. Take your time with each size, and listen to your body.

Tested and quality-checked

Every new line we stock is inspected by hand before it goes live — we check the build, the finish, and the materials, and we confirm it is safe and fit for how it will be used. Nothing is used for its intended purpose; it is examined, checked, and re-boxed. What that means for you is simple: you receive a piece we have already vetted, not a guess off a supplier's pallet.

How it compares

Metal plugs like this one are rigid and non-yielding, offering firm, consistent pressure and excellent temperature play. Silicone plugs, by contrast, flex and conform to your body, which some users find more forgiving during insertion. Slide Easy Prostate Plugs offer another material approach if you prefer something different. Metal lasts indefinitely and requires minimal maintenance; silicone can eventually degrade and may absorb odours. Choose metal if you want durability, temperature sensation, and weight; choose silicone if you prefer flexibility and a softer feel.

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 trainer kit with Cock Ring Sets to add erection support and heightened sensation during anal play. A ring maintains firmness while you're wearing the plug, intensifies orgasm, and lets you focus fully on the sensations the plug delivers. Together, they create a more complete experience during partnered or solo sessions, letting you explore multiple forms of stimulation at once.
