Product details

Core Definition

Rhythm of the Progenitor is an open-ended extension sleeve with a ridged outer shell: 19.0 cm long over an 11.3 cm inner cavity, adding about 7.7 cm in front of the wearer. Platinum-cured silicone at Shore 00-0, at a maximum outer diameter of 5.1 cm.

How It Works

Stretch fit. The cavity is a single open tube at Shore 00-0, one of the softest grades in production silicone, so it stretches to the wearer rather than sizing to him. The bulbous ring at the base seats behind the scrotum and keeps the sleeve from walking forward as the stroke reverses.

Extension geometry. An 11.3 cm cavity inside a 19.0 cm body leaves 7.7 cm of solid silicone ahead of the wearer's tip. Maximum circumference is 15.7 cm at the middle of the shaft, and the ridged section runs the full extension, so the added length is not a smooth filler cap.

Sequential ridge contact. The shell is cut into raised blocks stacked in transverse rows, with deep channels between rows. Each row crosses the entrance as its own event, so movement reads as a repeating sequence of steps rather than one continuous slide, and the rate of that sequence tracks stroke speed directly.

Who It's For

The 11.3 cm cavity is the limiting dimension and it is the shallowest of the three sleeves in this group, so longer wearers should size up to a deeper cavity. It suits couples who want the added girth to come with a strong, regular friction pattern. Not for anyone who wants a smooth or skin-like surface.

Care & Safety

Molded from 100% platinum-cured silicone: non-porous, phthalate-free and heat-stable. Wash with warm water and mild soap, or a dedicated toy cleaner, before and after every use; boil for two to three minutes for full sanitization. Use water-based lubricant only, as silicone lubricant attacks the surface. Dry completely, then store flat and away from other silicone items. Stop use if you feel pain, use a barrier when sharing, and keep away from anyone under 18.
