The Master Series Oculus Stainless Steel Anal Explorer is an adjustable anal expander made for medical play and slow, controlled stretching. Six rounded steel rods open outward from a central ring, each set by its own wingnut, so you can widen the opening a fraction at a time and hold it there. It's built for experienced players who already know their limits and want precise control over the stretch.
At the centre is a solid steel ring with a 4.1-inch inner opening. Six smooth rods hang from it, each ending in a small rounded ball. Each rod sits on its own threaded screw with a wingnut, so you can move them outward one at a time rather than all at once. Closed, the ball ends sit together at about 1 inch across; fully opened, they reach 4.1 inches. The insertable section is 2.9 inches long. Only the polished rods and balls touch the body. The spiral threads and wingnuts stay outside, resting against the buttocks.
This is an anal expander for people already comfortable with anal play who want to explore gaping, stretching or clinical-style scenes. It is not a first anal toy. If you haven't yet worked up through plugs of increasing size, start there and come back to the Oculus later. Partners should talk through limits, a safe word and how the scene will stop before anything goes in. The person wearing it is in charge of the pace, even when the other person is turning the wingnuts.
Prepare with plenty of thick lube on the rods and ball ends, and keep it off the wingnuts so your fingers can still grip them. Bring all six rods together before insertion. Ease the closed tips in slowly while the receiving partner breathes out. Once the ring is resting against the body, open the rods a little at a time, working around the circle so the stretch stays even, and pause between turns. Add lube as the opening widens. Watch and listen closely: discomfort, a sharp feeling or a request to stop means you close the rods back down at once. Going past someone's limit risks tearing.
The open ring is wide enough to fit a fist through, which some couples use as a guided warm-up for fisting. Trim and file nails, check hands for cuts, glove up if you like and use far more lube than you think you need.
The Oculus is nickel-free stainless steel, strong and non-porous, and it works with every type of lube, including silicone and oil. That makes it simple to sanitize. Wash it in warm water with mild soap, or boil it in water, then spray it with isopropyl alcohol and wipe it clean. Pay attention to the threads and wingnuts, where lube likes to hide, and dry everything fully before storage to keep the moving parts turning smoothly.
