Tunnel Fuckplug #4 X-large Black

The Tunnel Fuckplug #4 X-large Black by Oxballs is a spherical, hollow-core anal toy designed for users seeking intense fullness and dual-stimulation capabilities. Crafted from pure platinum silicone, this plug features a unique internal chamber that allows for double penetration or other insertive play, making it a versatile choice for experienced enthusiasts looking to expand their sensory repertoire.

Constructed from Oxballs’ signature Pure Platinum Silicone, this device offers a soft, squishy tactile experience that prioritizes body safety with a phthalate-free, non-toxic formula. The material’s distinct flexibility allows the plug to conform to the body, while the thick, reinforced shape ensures durability. The exterior surface is textured to provide a "retreading" sensation, gently stimulating the anal opening as it is inserted and worn. This texturing, combined with the bulbous design, helps keep the plug snugly in place during use.

The defining feature of this product is its hollow core, which transforms the plug from a simple insertable into a multi-functional device. The inner chamber is lined with nubs and ridges that provide stimulation when penetrated by another toy or body part. This design facilitates double penetration, allowing for simultaneous internal and external stimulation. The tapered neck leading into the bulbous body aids in insertion, guiding the plug smoothly into place while the wide base ensures secure handling and prevents accidental loss.

Users should note that the softness of the pure platinum silicone can make initial insertion challenging for some. The material’s squishiness requires patience and the liberal application of water-based or hybrid oil lubricants to ensure comfort and safety. Once inserted, the plug’s design fills the space while spreading the area wide, offering a unique sensation of fullness. The internal ridges and nubs create a stimulating environment for any secondary insertion, enhancing the overall experience through varied textures.

Care for this device is straightforward, reflecting the high quality of the silicone material. It can be washed thoroughly with warm soapy water after each use and is even dishwasher safe for convenient cleaning. To maintain the integrity of the silicone and prevent dust accumulation, it is recommended to store the plug separately in a breathable cloth pouch or a clean cotton sock. This storage method protects the textured surfaces and keeps the toy ready for future use without degradation.

With dimensions that include a total length of 5.5 inches and a width ranging from 2.75 to 5 inches, this X-large size is intended for those accustomed to larger inserts. The smallest usable circumference is 6.75 inches, expanding to a largest usable circumference of 10 inches, with an inner hole circumference of 4.75 inches. Weighing 13.4 ounces, the substantial weight contributes to the feeling of fullness and security. Buyers should prioritize proper lubrication and a slow insertion process to accommodate the soft material and achieve optimal comfort.
