Master Series Nipple Amplifier Pyramid Pumps

Master Series Nipple Amplifier Pyramid Pumps with 8 O-Rings in Canada

The Master Series Nipple Amplifier Pyramid Pumps combine vacuum pumping with graduated retaining rings for users who want temporary nipple enlargement and a more pronounced, erect appearance after pumping. The set contains two different pump sizes and eight O-rings, with four graduated ring sizes represented across the set so you can select a closer fit. The Large pump has a 0.53-inch inner opening, while the Small pump measures 0.35 inches internally. After pumping, a selected flexible ring can be transferred to the base of the nipple to help maintain the effect temporarily. Available in Canada from Discreet Life.

Two Different Pump Sizes

The set includes both a Large pump with a 0.53-inch inner opening and a Small pump with a 0.35-inch inner opening. Having two chamber sizes gives the user more flexibility when choosing a closer fit.

Eight Graduated O-Rings Included

Eight flexible rings are supplied in four graduated inner diameters ranging from approximately 0.33 to 0.54 inches. Select an appropriate ring before pumping so it can be transferred toward the nipple base after the desired temporary fullness is achieved.

Vacuum Pumping + Retaining Ring System

Unlike ordinary nipple suction cups that are simply removed after pumping, this system is designed around a two-stage approach: create vacuum with the pump, then use a selected ring to help temporarily maintain the enlarged appearance.

2.63-Inch Pump Length

Both pumps measure approximately 2.63 inches long, providing a compact chamber focused directly around the nipple rather than surrounding a broad area of the chest.

Compare Master Series Nipple Suction & Pumping Toys

Nipple Amplifier is different from the standard suction cups because it includes graduated retaining rings for use after pumping. Compare it with these alternatives if you prefer a simple silicone plunger, mechanically adjustable vacuum or suction combined with powered vibration.

A compatible lubricant can help create a better pump seal when needed, while toy cleaner makes routine care easier for the reusable pumps and rings. Keeping the set clean and selecting the correct ring size are especially important with a multi-piece pumping system.

How to Use

• Select a retaining ring that fits comfortably without excessive tightness.
• Place the selected ring over the open end of the appropriate pump before pumping.
• Centre the pump over the nipple and create suction gradually.
• Stop increasing vacuum when a comfortable level of fullness is reached.
• Slide the ring carefully toward the base of the nipple as directed by the product design.
• Monitor colour, warmth and normal sensation while a ring is in place.
• Remove the ring immediately if the nipple becomes numb, cold, very dark or unusually painful.
• Clean the pumps and all rings thoroughly after use.

Important fit note: The retaining rings restrict tissue expansion after pumping, so choose the least restrictive size that achieves the desired effect and monitor circulation closely.
