SUPERSIZER II Cock Pump by Nasstoys

Nasstoys SUPERSIZE II is a penis pump featuring an 8-inch cylinder with powerful suction and stem-u-nubs for targeted stimulation. The ABS plastic construction with silicone nubs delivers controlled vacuum intensity through an EZ release valve. Designed for men seeking enhanced sensation and size exploration, it suits those wanting customizable suction strength during solo or partnered play.

About SUPERSIZE II

The SUPERSIZE II creates a strong vacuum that stimulates blood flow and enhances sensation through progressive suction intensity. The stem-u-nubs inside the cylinder provide textured contact against sensitive tissue, adding dimensional stimulation beyond basic pumping action. The EZ release valve lets you modulate vacuum pressure precisely, building intensity gradually or maintaining consistent suction based on your preference.

ABS plastic construction provides durability that withstands repeated use without warping or degrading. The soft silicone nubs remain flexible through extended sessions, maintaining their stimulating texture without hardening over time. For those seeking reliable penis pump performance with internal texture, our anal play lubes collection offers compatible options for comfortable, friction-free use.

Key Features

• 8-Inch Cylinder: Generous internal space accommodates varying sizes and allows room for expansion during use.
• Stem-u-Nubs Design: Textured silicone ridges provide targeted internal stimulation beyond standard smooth chambers.
• EZ Release Valve: Precise control mechanism lets you adjust suction intensity without breaking the seal.
• Body-Safe Materials: ABS plastic cylinder paired with soft silicone nubs ensures safe, durable construction.
• Ergonomic Grip: Contoured design provides secure, stable handling during extended pumping sessions.

How to Use SUPERSIZE II

Basic Use

1. Apply generous water-based lubricant to your penis and the inside cylinder surface to reduce friction and create an effective seal.
2. Slowly insert your penis into the pump opening, ensuring comfortable positioning and a secure fit against the cylinder walls.
3. Activate the suction mechanism by beginning gentle pumping motions, allowing your body to acclimate to the sensation gradually.
4. Use the EZ release valve to adjust vacuum intensity upward, finding the pressure level that feels stimulating without discomfort.
5. Experiment with different pumping speeds and rhythms, discovering what combination of motion and suction intensity works best for your body.
6. After reaching desired results, slowly release pressure using the EZ release valve before carefully removing the pump.

Extended Use

Combining the SUPERSIZE II with manual stroking creates layered stimulation that many find more intense than pumping alone. Pairing the pump with a masturbator sleeve during sessions can intensify sensation through dual contact points. For those interested in extended sessions, taking breaks between pumping cycles prevents fatigue while maintaining arousal buildup over longer timeframes. Our body-safe anal lubricants collection includes premium options designed for sustained friction-free use.

Care Instructions

After each use, thoroughly clean the cylinder and nubs with fragrance-free toy cleaner and warm water, ensuring all lubricant residue is removed. Dry all components completely before storing in the included pouch to prevent moisture accumulation. Store in a cool, dry location away from direct sunlight, which can degrade silicone over time. Avoid petroleum-based lubricants, which damage silicone components; water-based formulas protect both materials and maintain seal integrity.

Materials and Safety

The SUPERSIZE II combines body-safe ABS plastic with medical-grade silicone nubs, creating a non-toxic construction suitable for sensitive tissue contact. The water-resistant design allows thorough cleaning without damaging internal components. ABS plastic resists warping through repeated use and temperature changes, while silicone maintains flexibility indefinitely. Avoid petroleum products that degrade silicone; water-based lubricants preserve material integrity and ensure long-term performance without compromising safety.

Who Is SUPERSIZE II For?

Suits men seeking enhanced sensation through textured internal stimulation and controlled suction intensity. Ideal for those curious about penis pump benefits without committing to basic designs lacking internal features. Appeals to experienced users wanting customizable vacuum control rather than fixed-pressure alternatives. Works well for partnered play where visual enhancement combines with sensation exploration. Suits those prioritizing material durability and realistic internal texture over novelty designs.

Why SUPERSIZE II Matters

For men accustomed to smooth-walled pumps that deliver generic suction without internal variation, the stem-u-nubs transform the sensation from simple pressure into textured stimulation that responds to different angles and rhythms. The EZ release valve removes the frustration of fixed-intensity pumps where you're locked into one pressure level—instead, you modulate intensity in real-time, building sensation gradually or intensifying suddenly based on what feels effective in the moment. For those skeptical that penis pumps deliver meaningful sensation beyond novelty, discovering how textured internal contact combined with controlled vacuum creates sustained arousal shifts what seems possible from this product category. The substantial 8-inch chamber provides room for full expansion without cramping, letting your body respond naturally rather than feeling confined. This combination of internal detail, pressure control, and generous sizing means the SUPERSIZE II works for men who previously felt limited by basic pump designs.

Independent Tester Review

Our independent testers evaluated suction consistency, nub texture durability, valve responsiveness, and seal integrity across multiple sessions. The EZ release valve maintained precise pressure control throughout testing, and the silicone nubs showed no degradation after extended use with water-based lubricants.

Testers reported that the textured interior created noticeably different sensation compared to standard smooth cylinders, with the stem-u-nubs providing consistent contact variation as positioning changed. The 8-inch chamber accommodated various sizes comfortably without excessive internal space. Individual results may vary based on anatomy, sensitivity, and usage patterns.

Understanding how vacuum pressure affects blood flow and sensation helps you use the SUPERSIZE II more effectively, adjusting intensity based on your body's response rather than guessing optimal settings. Progressive suction—starting gentle and building gradually—creates more sustainable arousal than immediately maximizing pressure.
