SSND-Double Expansion 12"

For users who desire a medium-length instrument combined with two strategically placed expanded areas of stimulation and stretching. Designed to offer an exceptionally comfortable yet intensely satisfying experience, this dual-wave sound provides unparalleled flexibility and pressure dynamics, making it a spectacular choice for training or extended wear.

Alternating Dual-Expansion Mechanics: The architectural layout of the Double Expansion sound is sculpted to deliver alternating waves of internal pressure and muscular relief along its entire 11.5-inch insertable length.

• Guided Tracking Tip: Features a smooth, rounded 9mm elongated tapered tip that steps into the urethral canal smoothly, gently, and gradually.

• Primary Expansion Zone: Smoothly scales upward from the tip to a substantial 14mm maximum diameter across the first segment to create a powerful initial stretch.

• Muscular Relief Valley: Abruptly tapers back down behind the first crest to a slender 8.4mm section, allowing the surrounding tissue a localized zone to contract and relax.

• Secondary Expansion Zone: Repeats the elongated taper back up to a final 13.7mm peak diameter, ensuring deep, consistent dual-point stimulation.

• Retention Flange: Drops down to an 8.5mm retention valley directly in front of the flared 14.2mm base to lock the sound securely in place during hands-free wear.

Anatomical Design & Shared Dimensions:

• Total Length: Measures a stable 12.25” (310mm) from end to end.

• Insertable Length: Provides a generous 11.5” of fully usable, insertable depth.

• Dual-Wave Profile: Features two distinct wide-body expansion nodes (14mm and 13.7mm) separated by an ultra-flexible narrow tracking valley.

👑 Bob's Choice Recommendations

• Experience Level: Advanced (Previous Experience Required). Because this model scales up to a maximum diameter of 14mm, it is classified as a more advanced-level training sound that requires previous stretching experience.

• The Prime Durometer Recommendation: Bob highly recommends ordering this model in our extra-soft #00-50 (soft) material composition. Selecting this ultra-pliable density creates an incredibly unique sensation; the sound remains beautifully compressible during insertion and gently stretch the urethra outward while inserted.

• Bob's Lubrication Tips: Bear in mind that our very soft, pliable #00-50 silicone takes a little more high-quality lubrication and slightly more effort to get introduced. Take your time and apply lubricant generously to both the sound and the canal

Color Options: #18 and #30 are available in pure translucent. #00-20, #00-50, and #10 base colors are translucent white and can be mixed with any standard color.
