LongSlim. 12 Inch Dildo Twister Textured Anal Suitable PVC Suction Cup Base

Longslim 12 & 1/4″ Slim Depth Training Dildo 

Over 10 inches of serious insertable depth in a strategically slim 1 & 5/8-inch diameter. Built for committed depth training without overwhelming girth.

If you want exceptional reach without battling extreme width, Longslim delivers. With 10 & 1/2 inches insertable and a manageable 1 & 5/8-inch diameter, this is a genuine deep training tool for experienced users. It’s also available as a full strap-on set for those wanting a complete strap-on set or pegging kit UK setup. Longslim is part of our harness compatible dildos, suction cup dildos, anal dildos, gay dildos and very big dildos collections.

Product Overview

Longslim is engineered for one purpose: maximum achievable depth. At 12 & 1/4 inches total length and 10 & 1/2 inches insertable, it comfortably exceeds standard “long” toys, most of which stop at 7–8 inches usable length.

The difference here is the balance. This is not an extreme girthy strap-on or oversized 2+ inch diameter monster. Instead, the 1 & 5/8-inch diameter (4 & 3/4-inch circumference) allows deeper penetration without width becoming the limiting factor. If you’ve ever wanted to focus purely on depth progression, this is the tool.

The twisted undulations along the shaft add continuous texture during insertion and withdrawal, delivering tactile stimulation while also helping gauge depth visually and physically. The powerful suction cup base allows for hands-free use and full compatibility with most harness systems, making it suitable for solo training or use within a strap-on set.

Product Specifications

Size & Girth Positioning

In terms of girth, 1 & 5/8 inches sits just above average. This is not a beginner toy, but it is far more manageable than a girthy strap-on or 2-inch+ diameter dildo. The slim build makes it ideal for those already comfortable with standard toys and ready to push depth rather than width.

Intensity level: Advanced depth, moderate girth.

Harness & Strap-On Compatibility

The suction cup base fits securely into compatible harness systems, making Longslim suitable for strap-on use. Because of its slim diameter and balanced 450g weight, it performs well in a strap-on set without becoming unstable or overly heavy for the wearer.

If you’re building a pegging kit UK setup, this provides serious depth potential while remaining practical for controlled thrusting. For those wanting everything in one purchase, a complete strap-on set option is available.

Ideal For

• Experienced users ready for 9–10+ inch depth progression
• Anal depth training enthusiasts
• Users who find girth limiting but want more length
• Those building a serious pegging kit UK
• Depth-focused strap-on set users

How to Use

Depth progression is key. If 10+ inches is new territory, start with the depth you’re already comfortable with and increase gradually over multiple sessions.

Use generous water-based lubricant along the full shaft. Because this is a depth-focused design, full-length lubrication is essential.

For suction cup use, mount on a clean, smooth surface. Hands-free positioning allows better angle control and makes it easier to control pace and insertion depth.

For harness use, ensure correct O-ring sizing and maintain clear communication if used with a partner. With 10 & 1/2 inches insertable, control and patience matter.

Care & Cleaning

Wash thoroughly after each use with warm water and antibacterial soap or a dedicated toy cleaner. Pay attention to the twisted texture where residue may collect.

After anal use, ensure deep cleaning before reuse. Allow to dry completely before storage. Store separately from other toys.
