Not for the faint-hearted, the 4" Medium Pig Hollow Butt Plug by Oxballs is here to stretch your limits and challenge everything you thought a butt plug could be. Designed with hardcore users in mind, this isn’t just a plug — it’s an invitation to go deeper, feel more, and unleash the full force of your kink.

This beast is sculpted from Oxballs’ exclusive FLEX-TPR — soft, smooth, and insanely stretchable. It’s built to morph with your body while delivering relentless pressure right where you crave it. The flanged neck and flattened base keep it locked in place, so you can move, push, and grind without worrying about pop-outs or slippage.

What sets this apart? The hollow core. You’re not just plugging — you’re opening up new possibilities. Pour in lube, shoot in water, slide in toys, or just stare into the abyss. It’s raw, filthy, and absolutely hypnotic.

• FLEX-TPR material – delivers a slick, flexible stretch you can feel
• Hollow tunnel design – doubles as a conduit for lube, toys, or penetration play
• Flattened flared base – built for comfort and long-term wear
• Expert-level intensity – not for beginners; serious stretch for serious players
• Visual depth play – the open core lets you see and explore deep inside

This isn’t your average plug — this is advanced territory. Hollow butt plugs are a whole different game, opening you up to sensations, access, and visuals most toys can’t touch. If you’re building a collection that truly explores male sex toys at the edge, a hardcore tunnel plug like this is a must-have.

4" Medium Pig Hollow Butt Plug is the one you bring out when it’s time to level up. Add it to your arsenal and push your play to the next level.

We’re not your average adult shop — Naughty Boy is built for men who crave more.
