Meet HULK, the monstrous flexTPR™ cocksheath built for players who crave size beyond size. This beastly sheath turns your shaft into a massive, heavy, vein-bulging slab of dick with 3–5x more girth and 5–7 extra inches of length, delivering a devastatingly thick, deep, and powerful experience for any hole that can handle it.
Made from OXBALLS’ signature super-stretchy, rubbery flexTPR™, HULK wraps around your shaft with a warm, fleshy feel that sucks you in and molds to your size. The built-in COCKSLING base locks everything in place—hard or soft—while the interior grabs your shaft with heavy ridges, thick nubs, and textured stroker channels that pump, tug, and work you with every thrust or JO stroke.
Use it as a stroker or as a hulking extension for partner play—either way, HULK hits hard. The suction effect increases as you squeeze the air out during insertion, creating an intense vacuum that pulls you deep into the sheath.
