You want serious dual penetration but worry that most toys won't deliver the depth and girth you need. The Smooth Double Header 18 Dong is an 18-inch medical-grade silicone double ender built for advanced users who demand intense, full-body stimulation and complete control.
Smooth Double Header 18 Dong is a heavyweight dual-headed penetration toy from Doc Johnson. Built from premium medical-grade silicone, it measures a full 18 inches with two distinct heads—one 6 inches, one 7 inches—each offering different texture and girth. The flexible yet firm shaft enables deep insertion and aggressive play. Its non-porous construction stays hygienic and resists bacterial growth, making it a reliable choice for intensive BDSM scenes.
This dong stands apart because both heads deliver different sensory experiences in a single toy. The varied girths and textures create unique internal stimulation across multiple zones. See the full BDSM Australia range of Double Ended Dildos to compare other dual-headed options.
Apply generous water-based lubricant to both heads and the intended insertion area. Position the toy carefully, then slowly introduce one head at a time. Control depth and speed based on comfort and arousal. Adjust angle and movement to target specific internal areas. Communication with partners is essential—check in frequently and establish clear signals for stopping.
For double penetration, use both heads simultaneously once you're comfortable with single insertion. Vary rhythm and depth to build intensity. Explore different positions that allow you to control penetration depth. Combine this toy with Lubes and Essentials to ensure smooth, safe play. Always clean thoroughly with warm water and mild soap before and after each session.
Wash the toy with warm water and mild antibacterial soap immediately after use. Rinse thoroughly and air dry completely before storage. Store in the provided protective bag away from direct sunlight and extreme heat. Keep away from silicone-degrading products. Water-based lubricants only—never use oil or silicone-based lubes, which damage the material.
Understanding your body's response to intense penetration helps you play safely and confidently. Read the Chastity Guide for broader insights into control and sensation play. Research double-ended toys and dual penetration techniques to get the most from your experience.
This dong's 18-inch length and dual heads make it a formidable tool for breaking resistance. Slow, deliberate insertion teaches my submissives the value of patience and surrender. Watching them struggle against restraints as each head enters creates the perfect foundation for deeper obedience work.
The varied textures deliver unpredictable sensation—my submissives never know which head will move next or how deep I'll push. Control becomes absolute when they realize they cannot anticipate my movements. Psychological impact matches physical intensity; the toy becomes a symbol of my authority.
Temperature play adds another layer. Warming or cooling the silicone shifts their focus between pleasure and discomfort, keeping them mentally present. My submissives learn that this toy exists solely for my pleasure and their instruction. Aftercare following intense scenes with this dong reinforces trust and deepens the power exchange.
