Apply water-based lubricant generously inside the sleeve and on yourself. Insert your penis into the sleeve, either with or without the black case depending on your preference. The textured interior—featuring beads, spirals, and spikes—will deliver dynamic sensations with every stroke. Experiment with grip pressure and speed to customize your experience.
Pro tip: Use the transparent sleeve without the case for maximum visual stimulation, or keep it in the case for a firmer, more controlled grip.
