Fun Factory Sonic Vitamin brings double penetration fantasies to life with its 40cm flexible design and dual-ended construction. Two different sizes - 3.5cm and 4.5cm diameter - let you choose your intensity while the curved shape targets your G-spot from multiple angles during solo or partner play.
Both ends slide in smoothly thanks to the tapered tips, while the flexible silicone bends to follow your body's natural curves. The smaller 3.5cm end works perfectly for anal play while the thicker 4.5cm end fills your pussy completely. When you're using both ends simultaneously, the constant pressure against your internal walls creates that full, stretched sensation that builds toward explosive orgasms.
Your clit gets indirect stimulation from the base rocking against it as you move the toy, while your G-spot and anal walls experience constant contact. The deep pressure triggers those rolling, full-body orgasms that leave your legs shaking. Many users report squirting for the first time with this level of internal pressure and stimulation.
Start with plenty of water-based lube on both ends and begin with the smaller 3.5cm tip. Insert slowly while your muscles adjust to the girth, then work toward the thicker end if you want more fullness. For double penetration, position the thicker end vaginally first, then guide the smaller end into your ass while maintaining the angle that hits your G-spot.
Rock your hips to create internal massage rather than thrusting in and out - the length gives you leverage to create rolling pressure against both your G-spot and anal walls. When you feel your muscles starting to tighten and pulse around the silicone, maintain that rhythm until the waves hit. The fullness intensifies every contraction during climax.
This works best for people comfortable with larger toys and double penetration. The 4.5cm thick end requires some experience with girthier dildos, while successful double penetration needs patience and proper warm-up. Couples exploring pegging or shared penetration will find the length perfect for creative positioning. Not recommended for anal beginners - start with smaller dedicated anal toys first before attempting the thicker end anally.

This represents the advanced end of our Sex Toys collection with its substantial size and dual-penetration design. The 40cm length and varying girths place it in the premium category for experienced users seeking intense fullness. Choose this over standard dildos when you want simultaneous stimulation or partner sharing capabilities.
While browsing Vibrators, this dildo offers a non-vibrating alternative that creates sensation through size, shape, and manual movement instead of motors. Many users combine this with bullet vibrators for external clit stimulation while experiencing the internal fullness and G-spot pressure that only manual dildos provide.
The medical-grade silicone felt substantial but not intimidating when I first handled the Sonic Vitamin. Starting with the 3.5cm end, insertion was smooth with adequate lube, and the tapered design made the transition comfortable. The real revelation came when I attempted double penetration - the 40cm length gave me complete control over angles and pressure. The thicker 4.5cm end hit my G-spot consistently while the smaller end created that full sensation anally. My partner was impressed watching me handle both ends simultaneously, and the visual added to our excitement. The flexibility meant I could rock and twist without the toy slipping or losing position. When my orgasm built, the fullness made every internal contraction more intense - those deep, rolling waves that seem to last forever. Cleanup required thorough attention to both ends, but the silicone rinsed clean easily.
Order your Fun Factory Sonic Vitamin from the cockringshop for serious double penetration experiences. The dual-diameter design and medical-grade construction deliver the intense fullness and G-spot pressure that smaller toys simply can't match.
