Dong Extension by Sono

SONO No. 19 Dong Extension is a TPE penis sleeve with integrated butt plug designed for dual stimulation and length enhancement. Measuring 341mm total length with a 35mm extension and 81mm plug, it features a secure ball strap and curved prostate-targeting design. The soft TPE construction is waterproof and phthalate-free, suited for partners seeking combined penetrative and anal play without complex positioning.

About SONO No. 19 Dong Extension

The SONO No. 19 works through a dual-chamber design: the sleeve extends the penis by 35mm while the attached butt plug delivers simultaneous anal stimulation through its curved tip. The secure ball strap holds both components firmly in place during movement, preventing slippage or shifting. The slightly curved plug tip naturally contacts the prostate, creating layered sensation that builds through both entry points simultaneously.

Soft TPE construction delivers the realistic texture that rigid materials cannot replicate, while remaining durable enough for repeated use. The waterproof design supports easy cleaning and shower play, and the phthalate-free material ensures body safety during extended wear.

How to Use SONO No. 19 Dong Extension

Basic Use

1. Apply water-based lubricant generously to the sleeve interior and the wearer's penis. PharmQuests lubricant is recommended for optimal comfort and glide.
2. Slide the sleeve over the penis, ensuring the ball strap sits comfortably at the base without restricting circulation.
3. Position the attached butt plug at the receiving partner's anal opening. Use additional lubricant on the curved plug tip for smooth insertion.
4. Insert the plug slowly, allowing the receiving partner's body to adjust to the curved tip before proceeding deeper.
5. Once both components are positioned, begin thrusting at a pace that allows the receiving partner to feel the dual stimulation building gradually.
6. Adjust depth and rhythm based on comfort feedback, as the 90mm spacing allows independent movement of each component.

Extended Use

Pairing SONO No. 19 with a clitoral vibrator creates layered sensation that many partners find more intense than either stimulation alone. The curved plug naturally targets the prostate while the sleeve provides internal contact, allowing synchronized pleasure that coordinates both partners' arousal. For those exploring anal play for the first time, the integrated design removes the complexity of managing separate products.

Care Instructions

After use, rinse the entire product thoroughly with warm water and mild soap, paying special attention to the textured plug base where lubricant accumulates. Pat dry with a soft cloth and allow it to air-dry completely before storage. Store in a cool, dry location away from direct sunlight, as TPE can degrade under prolonged UV exposure. The waterproof design supports shower cleaning but keep the ball strap connection dry between uses.

Materials and Safety

SONO No. 19 is manufactured from soft TPE, a non-porous material that resists bacterial growth and supports thorough cleaning. The phthalate-free construction ensures body safety during extended wear, and the waterproof design allows temperature play and shower use without degradation. Soft TPE delivers realistic texture while remaining durable enough for repeated use over years rather than months.

Who Is SONO No. 19 Dong Extension For?

Suits couples seeking combined penetrative and anal stimulation without managing separate products or complex positioning. Those exploring anal play for the first time benefit from the integrated design and curved prostate-targeting shape. Partners interested in extended length combined with simultaneous internal contact appreciate the 35mm extension paired with the plug's independent stimulation, allowing both partners to experience layered sensation during shared play.

Why SONO No. 19 Dong Extension Matters

For couples who find anal play feels isolated from penetrative sensation—where one partner focuses on the plug while the other experiences sleeve contact—the integrated design creates unified pleasure where both forms of stimulation happen simultaneously. The curved plug tip naturally contacts the prostate while the extended sleeve provides internal gliding, allowing arousal to build through layered sensation rather than competing sensations. For partners accustomed to choosing between penetration and anal play, discovering that both can happen together through a single product shifts what shared exploration feels possible. The ball strap security means neither component shifts during motion, allowing focus on sensation rather than repositioning. For those hesitant about dual play because managing separate products felt awkward, the integrated design removes that barrier entirely.

Independent Tester Review

Our independent testers evaluated the ball strap security, sleeve glide consistency, plug insertion comfort, and dual-stimulation coordination. The strap remained firmly positioned through varied thrusting depths and rhythm changes, and the curved plug tip delivered consistent prostate contact without shifting sideways. Tester feedback confirmed the 90mm spacing allows independent movement of each component while maintaining coordinated stimulation.

The soft TPE sleeve provided realistic internal texture without excessive drag, and the waterproof design supported easy cleaning and temperature play. Testers noted the curved plug tip eases initial insertion more effectively than straight designs, and the textured base creates noticeable prostate sensation. Individual results may vary based on anatomy, sensitivity, and usage.
