Star Force 4 Dual Steel Prostate Stimulator Sphere + Bulb 26 cm

On one side, a perfect sphere to embrace the sphincter; on the other, a smooth bulb for deep penetration. The marked S-handle gives you exact control over the angle, and 1.4 kg of steel descends without you having to force it.

Incidentally, the sphere holds the sphincter in place

A truly rounded ball at one end—not just a mere bulge, but a full sphere separated from the handle by a thinner neck. You feel the sphincter stretch as it passes, then close behind it, and the sphere remains lodged beyond. This is exactly the sensation we're looking for in stationary metal butt-plug play, without having a real plug.

On the other side, the bulb for depth

The other end is a wider, elongated ovoid bulb—the angle for deep penetration, more classic but amplified by the weight. You use the curved S-handle as a grip to aim: the tip reaches the prostate more directly than with straight models. The handle is narrow for a good grip, and the weight remains centered near the end you insert.

With the S-shape, you reach the prostate

The pronounced curvature of the Star Force 4 is more distinct than on other models in the range. Advantage: you don't have to twist your wrist to reach the prostate; the handle directly gives you the right angle. Disadvantage: it takes a bit of practice to hold the object without it tipping over. Once you find the grip, it offers a comfort that straight models do not.

Submerge it chilled for maximum stimulation

The modest diameter (3.5 cm) makes it accessible to intermediate users—not a format for those who like large objects, but rather for those seeking precision and thermal sensation. 5 minutes in the fridge, and the sphere becomes particularly intense as it passes the sphincter. This is probably the format that best exploits the thermal play in the range.
