If you’re chasing the ultimate gape and want to take it all the way, the 5.5" Woof Hollow Butt Plug from Oxballs is how you answer the call. Squishy, stretchable, and seriously deep — this plug was built for filthy tunnel play that doesn’t hold back.

Crafted from Oxballs’ softest rubbery-flex material, this monster is built for comfort and extreme access. The tapered scoop design opens you up smoothly before settling into a thick midsection that pops your hole wide. Once it's in, the soft flanged base flattens perfectly when you sit or grind — no awkward edges, just raw stretch and pressure.

And the hollow core? It’s a gateway. Pour in the lube. Push in toys. Slide in fingers or even a vibe. Stream water. Look inside. It’s designed for guys who want their plugs to do more than just plug — it’s an access port for all your deepest kinks.
