Get Ready to Master Your Pleasure with MASTERJACK! 💪🍆

Hey pro-level gooners and hardcore strokers! If you crave something thick, heavy, and packed with pleasure, the MASTERJACK is here to elevate your JO game. This isn’t your average stroker—it’s a hefty, fleshy beast designed for those who love to go hard and deep. Get ready to experience the ultimate in solo satisfaction!

Key Features:

  • Dual-Function Pleasure: Two holes to explore—one with a tight, ribbed butt-pucker and the other with a ringed, gaping hole for a smoother ride.
  • Ergonomic Handle: Built-in handle with industrial diamond plate grips ensures a firm hold, no matter how wet and wild things get.
  • Extra-Soft Plus+SILICONE: Made from our softest silicone blend for a fleshy, warm feel with a suede-like finish.
  • Durable and Body-Safe: Non-toxic, phthalate-free, and designed for intense, prolonged use.

Unleash the Beast

Imagine this: you're deep into a marathon session, and you need something that can keep up with your relentless pace. MASTERJACK is your perfect partner. Its hefty build and fleshy feel make every stroke an intense experience, while the ergonomic handle ensures it stays in your grip no matter how greasy and sloppy things get.

With two distinct holes to choose from, you can customize your pleasure. The tight, ribbed butt-pucker offers intense stimulation, while the ringed, gaping hole provides a smoother, sloppier ride. Flip it over and switch up the sensation whenever you want—it's all about what feels best for you.

Lube Up and Go Hard

LUBE SAFE: Use with water-based or silicone-based lubricants for an ultra-slick experience.

Easy Care for Long-Lasting Fun

CARE: After your session, wash the MASTERJACK in warm, soapy water and let it air dry. Store it separately in a breathable cloth pouch or cotton sock to keep it in prime condition for your next goon-fest.

  • Length: 5.5 in / 14 cm
  • Width: 3 in / 8 cm

How to Use MASTERJACK

1. Getting Started:

  • Unpack and Inspect: Remove your MASTERJACK from its packaging and give it a quick inspection. Make sure it’s clean and ready for action.
  • Choose Your Lube: Apply a generous amount of water-based or silicone-based lube to both yourself and the stroker. This ensures a smooth and enjoyable experience.

2. Using MASTERJACK:

  • Select Your Hole: Decide which end you want to start with—the tight, ribbed butt-pucker for intense stimulation, or the ringed, gaping hole for a smoother, sloppier ride.
  • Insert and Enjoy: Slowly insert yourself into the chosen hole. Use the ergonomic handle to maintain a firm grip and control the stroker’s movement.
  • Adjust Your Grip: Squeeze the stroker and experiment with different angles and pressures to find what feels best. The ergonomic handle with diamond plate grips makes it easy to keep a solid hold, even when things get slippery.

3. Switching It Up:

  • Flip and Repeat: Want to change things up? Simply flip the stroker and slide into the other hole for a different sensation. The dual-function design lets you easily switch between the two textures for varied pleasure.

4. Two Guys, Double the Fun:

  • Share the Experience: MASTERJACK is designed to be enjoyed solo or with a partner. Two guys can use either end at the same time for an incredibly intimate and thrilling experience.
  • Get in Position: Align yourselves so that each of you has access to one end of the stroker. Lube up generously and insert into your respective ends.
  • Synchronize Your Movements: Communicate and find a rhythm that works for both of you. The shared sensation and mutual pleasure will take your connection to the next level.

5. Aftercare:

  • Clean Your Stroker: Once you’re done, wash your MASTERJACK thoroughly with warm, soapy water or your favorite sex toy cleaner. Ensure all lube and bodily fluids are removed.
  • Dry and Store: Pat dry with a clean towel and allow it to air dry completely. Store the stroker separately in a breathable cloth pouch or cotton sock to keep it in prime condition.

So, what are you waiting for? Grab your MASTERJACK and get ready to master your pleasure. It's time to go hard, go deep, and goon like never before! 💪🍆

Fun little ball!
Fun little ball! Glad I got the football version the regular ball would be a choking hazard for my Great Dane. The ball rolls and shakes on the floor which at first was scary, but now she loves it! She nudges it all over the floor to keep it moving, keeping her entertained for a bit.

Won't hold charge
Unfortunately the toy would not hold charge. I charged it for couple hours and it wouldn't turn on. I tired a different charger to be safe and still nothing. Was hoping to share this exciting toy with my pup, guess I'll keep looking for alternative.

Luxury Dog, Luxury Toy”
“ I previously tried another toy, but its outer layer peeled off easily and even caused issues .This ball, however, is different. Even though my little dog chews on it, the ball recovers easily and causes no damage. It even gives a gentle workout for my pup’s gums and teeth. Maybe because my dog is small, it seems to restore well and is a perfect fit! At first, I saw this advertised mostly for larger dogs. However, even though my pup is really small, they have no trouble playing with it and enjoy it just as much!

Dog loves it; but some poor construction
My small dog instantly loved this toy! I like the squeaker, bounciness, and options for different kinds of movement in the interactive play. It also recharges fast. However, I have two downsides: While my dog isn’t a big chewer, he got through this in a couple weeks. So we are on our second shell. That’s a nice option to be able to order just the shell. Second, both shells have the same issue: they won’t stay screwed shut. The second shell is worse at this than the first. Once unscrewed, the interactive/mechanism piece will fall out and chocks be a choking hazard. It also frustrates my dog and he just barks at it until I fix it. With the new shell I think I had to fix it 5 times in the first 10 minutes of play. Overall, it’s a fun toy and we’ll keep playing on!

Durable
Omg my dog loves this. The rubber is so durable my 2 yo aussie hasnt torn it up yet. I bought a cheap one from temu before and it took only 2 mins for my dog to tear it up it was complete waste of money. I love the football shape becahse it bounces unpredictably. I lile this to exhaust and exercise my aussie. This has become his favorite toy ever. It charges fast too. When im feeling lazy this is good way to exercise my dog and enrich him. I also teach him commands using this ball as his treat or reinforcement. Definitely worth every penny
