How To Use This Toy
The Juggernaut of the North: Yevich moves like a mountain come to life. Clad in shimmering chainmail and draped in a battle-worn bear hide, every step he takes radiates raw, unstoppable power. In his massive palm, he grips a heavy battle-axe etched with ancient runes—a legacy of conquest passed down through generations. He doesn't seek the shadows; he shatters the front lines.
The Runed Conquest: This sleeve is the embodiment of Yevich’s battlefield dominance. Its surface is etched with mystical rune textures and a massive, swelling knot designed to breach every defense. When you slide into this "bio-armor," you aren't just adding size; you are wielding a weapon of mass satisfaction. The relentless pressure of the Yevich knot ensures that every thrust is a legendary strike that forces total surrender.

Expert Tactics
Given Yevich’s massive 5.8 cm (2.28 in) max diameter, start slow. Use the heavy head to "knock" at the entrance, letting the rune textures create a buildup of anticipation before a full, room-filling thrust.
Use a high-density water-based lubricant. This allows the rune-etched grooves to "catch" and release against internal walls, creating a rhythmic, pulsing vibration during movement.
