Oxballs Invader Cocksheath

The Oxballs Invader Cocksheath is an open-ended penis extender designed for men seeking enhanced girth and intensified stimulation during partnered or solo play. By combining the secure fit of a traditional cocksheath with the sensory freedom of an open tip, this device allows for direct contact at the glans while providing substantial stretching and texture along the shaft for both the wearer and their partner.

Constructed from OxBalls' proprietary Plus+Silicone blend, this device offers a unique tactile experience that balances the softness of silicone with the stretch and durability of thermoplastic rubber. The material features a lush, dull finish that feels velvety to the touch, ensuring a comfortable fit without excessive friction. This specific polymer blend is water-resistant and easy to clean, making it a practical choice for various intimacy settings. The design prioritizes security, utilizing a patented sling base that anchors the device to the scrotum without the need for external straps, harnesses, or adhesives. This engineering allows the sheath to remain securely in place even during vigorous activity, eliminating the common frustration of devices slipping or shifting during use.

The defining characteristic of the Invader is its open-ended construction. Unlike closed sheaths that encase the entire penis, this design leaves the head of the penis exposed. This allows for direct skin-to-skin contact with a partner, preserving natural sensitivity and sensation at the most sensitive part of the anatomy. Simultaneously, the device adds significant girth to the shaft, creating a "humpy" profile that increases the fullness felt by the receiving partner. The shape is engineered to be thickest in the middle of the shaft and taper slightly toward the tip, ensuring that the added volume is distributed to maximize stimulation without compromising comfort.

Stimulation is further amplified by the device's intricate texturing. The exterior features deep, wavy ripples that run along the length of the shaft, providing continuous visual and tactile appeal. Inside, the tube is lined with bumpy, textured surfaces designed to massage the wearer's skin. This dual-texture approach ensures that both the person wearing the device and their partner receive high-level sensory feedback. The internal bumps stimulate the wearer's nerve endings, while the external ripples provide additional friction and pleasure for the partner. This makes the Invader particularly effective for those looking to intensify intercourse or oral sex without the use of lubricants alone.

Sizing is critical for optimal performance with this device. The usable shaft circumference ranges from 5.5 to 6.25 inches, accommodating a wide variety of penile sizes. The main hole circumference is approximately 3.93 inches, and the ball hole circumference matches this measurement, ensuring a snug fit around the testicles. The inner shaft depth is 5 inches, with a total device length of 6.5 inches. It is important to ensure that the shaft fits comfortably within the usable circumference range to maintain the secure seal of the sling base. If the shaft is too large, it may compromise the fit; if too small, the device may not stay securely anchored. The device weighs approximately 5.44 ounces, providing a substantial feel without being overly heavy.

Care and maintenance are straightforward. The Plus+Silicone material is non-porous and resistant to water, allowing for easy cleaning with warm water and mild soap or a dedicated toy cleaner. It is recommended to use water-based lubricants with this device, as oil-based products can degrade the TPR/silicone blend over time. Regular inspection for signs of wear, particularly around the sling base and the textured interior, ensures longevity and safety. Store the device in a cool, dry place away from direct sunlight to preserve the material's integrity and color.

This product is ideal for couples exploring power dynamics, sensation play, or simply looking to add variety to their sexual routine. It is also suitable for solo users who enjoy the feeling of enhanced girth and the psychological thrill of wearing a sheath. The open design makes it less restrictive than full encasement devices, allowing for natural temperature regulation and easier cleanup. Whether used for extended periods of play or quick sessions, the Oxballs Invader Cocksheath delivers a consistent, high-quality experience rooted in durable materials and thoughtful design.
