Vac-U-Lock Platinum The Dream No. 14 by Doc Johnson

A curved 7-inch platinum silicone dildo locked into a neoprene Supreme Harness via Doc Johnson's Vac-U-Lock system, designed for couples seeking secure, comfortable strap-on penetration with direct G-spot contact and zero slippage.

What it does

During penetration, the curved silicone shaft targets the G-spot directly with its pronounced head while gliding smoothly against sensitive internal walls. Body-safe platinum silicone feels firm yet flexible—rigid enough to deliver consistent pressure without uncomfortable stiffness. Arousal builds as the curved tip presses upward with each thrust, and the wearer feels every movement through the base connection while their partner enjoys sustained pressure against their most responsive areas.

Confidence grows when the Vac-U-Lock mechanism creates an airtight seal that locks the dildo firmly in place, eliminating slippage worries during vigorous thrusting. Weight distributes evenly across your hips and lower back through the Supreme Harness, so you can focus entirely on rhythm and depth without discomfort. Orgasms become more powerful when you can thrust without distraction or harness straps cutting into skin. Browse Strap On Me for other harness and attachment options.

Fit and sizing

Measure your waist and hip circumference at their widest points to confirm the adjustable neoprene harness suits your frame—it fits up to 69 inches comfortably. Different body types benefit from the cushioned design; those with back sensitivity particularly appreciate the support strap that prevents strain during extended wear. Beginners often prefer this system because the secure Vac-U-Lock attachment removes guesswork about sex toy stability, while experienced users love switching between different dildos mid-session using the included O-rings. At Cockringshop, we specialise in products for men and couples, so sizing advice is always available if you're between measurements.

How to use it

Adjust the neoprene harness straps snugly around your hips and waist before inserting the dildo into the Vac-U-Lock opening until you hear the click. Position the curved tip to point upward toward your partner's belly button for optimal G-spot contact. Start with shallow thrusts to let your partner adjust to the size and angle, then control depth and speed by gripping their hips or thighs while maintaining steady rhythm.

Angle slightly upward during penetration rather than straight in and out—the curve works best this way. Watch for signs of building arousal like increased wetness and muscle tension around the shaft as you vary your thrusting pattern. After use, clean the platinum silicone thoroughly with warm water and mild soap, then dry completely before storage. Vac-U-powder (included) makes removal from the harness quick and easy.

Feature breakdown

Who it suits

Couples wanting reliable strap-on sex without complicated setup or adjustment breaks will appreciate the straightforward Vac-U-Lock system and Supreme Harness comfort. Beginners benefit from the secure attachment that eliminates guesswork, while experienced users love the interchangeable design that lets them switch between different dildos mid-session. Those with back sensitivity will value the cushioned support strap that prevents lower back strain during longer sessions. The adjustable neoprene accommodates different body types comfortably.

Skip this product if you prefer rigid, non-flexible penetration or if your waist exceeds 69 inches—the harness won't fit securely. Those seeking vibration or motorised stimulation should look elsewhere, as this is a manual strap-on system without batteries or moving parts.

How it compares

Curved strap-on dildos like this one offer flexible, body-safe silicone that warms to skin temperature and flex slightly during use, targeting the G-spot through their shape rather than vibration. Compare this to Pornhub Sextoys, which include motorised and vibrating options that add external sensation and variable intensity but require batteries and more cleaning. The choice depends on whether you prefer curve-based targeting and sustained pressure (this product) or variable vibration patterns and motorised stimulation (vibrating alternatives). Both attach securely; the difference is flexibility and sensation type.

What you can use it with

Pair this strap-on with items from Couples Intimacy Kits to expand sensation during partnered play—complementary products work together during use to build arousal and intensify orgasm for both partners. Adding compatible sex toys creates layered stimulation that prolongs sessions and deepens connection, while the secure harness keeps everything in place during longer, more adventurous play.
