Brutus Ergo Bum XXL 15.4cm Silicone Tunnel Plug, Waves Of Fullness

Bold Curves, A Hollow Centre And Plenty To Look Forward To

The Brutus Ergo Bum XXL 15.4cm Silicone Tunnel Plug is for those who already know they enjoy generous anal toys and fancy a little more shape in the experience. Two rounded sections create a wavy profile, building from a 5cm upper diameter to a substantial 7.1cm at its widest point.

Its smooth silicone surface keeps the feel sleek, while the hollow tunnel adds another dimension to this bold design. Beneath those curves, a broad, upturned base gives you a reassuringly substantial place to hold.

Make some time, get comfortable and enjoy discovering what each contour brings. Whether you're enjoying your own company or sharing an unhurried evening with a trusted partner, this Brutus is all about savouring the fullness at your pace.

“Big curves, smooth silicone and a little invitation to take your time.”

Brutus Ergo Bum XXL Silicone Tunnel Plug Key Features:

✅ Hollow Tunnel Design: An open centre makes Ergo Bum a distinctive alternative to a solid butt plug.

✅ Two Rounded Sections: The wavy exterior pairs fuller curves with narrower waists, giving you changes in width to explore along the shape.

✅ Smooth Silicone Surface: A silky-smooth finish lets the contours take centre stage without added bumps or fine textures.

✅ Broad Curved Base: Wide, upturned ends provide a useful grip for handling and controlled removal, while the base remains outside the body.

✅ 15.4cm Overall Length: A generously proportioned design with a 2.8cm tunnel opening.

Product Details

Ergo Bum brings together the full feel of a large anal plug and the distinctive appeal of a hollow centre. The rounded tip flows into the first bulb, narrows through a waist, then builds to a fuller lower section before meeting the neck and broad base. It's a sculpted shape that gives experienced plug lovers something different to get acquainted with.

The changes in diameter are the main attraction. Rather than one continuous cone, you have separate rounded curves to enjoy as you ease the toy into place at a pace that feels right. That 7.1cm maximum diameter makes this a substantial piece, so compare it with the dimensions of toys you already enjoy when deciding whether it's your kind of fullness.

The hollow design has a 2.8cm opening, and the exterior remains smooth and untextured. In classic black silicone, it has a simple, purposeful look: the interest comes from the shape itself.

At the base, the two wide ends curve upwards to give your fingers something to hold. They're handy when a little change of angle helps you get comfortable, and for taking your time with removal. One piece, a distinctive silhouette and a very clear invitation to make pleasure the evening's main event.

Experience Level

For experienced anal users who are already comfortable with large toys and know their preferred fit. Ergo Bum XXL suits a considered next addition to an established collection, with time to warm up and enjoy the experience without rushing.

Best For

Those who love a substantial plug and want more shape to savour. If rounded bulbs and a fuller lower curve appeal more than a straight shaft or simple cone, Ergo Bum gives you a lovely reason to clear the diary for a slow evening in.

It's also a distinctive pick for experienced tunnel-toy fans. Bring it into a relaxed solo session, or make it part of a shared evening where you can talk, tease and take each change of contour at your own pace. No finish line to chase—just the pleasure of finding what feels good.

Not Ideal For

If you're new to anal toys, still enjoying smaller diameters or prefer a slim plug you barely notice, a gentler size will be a better match. If you love the feel of a completely solid plug or want built-in vibration, those styles offer a different experience. This one's charm is its generous, wavy shape and hollow centre.

Care & Use

Give yourself time to warm up with a familiar, comfortable toy first. Apply plenty of water-based lube to the plug and your body, then move slowly and let comfort guide you. Keep the broad base outside the body and stop if anything feels uncomfortable.

Wash before and after use with warm water and mild soap or toy cleaner. Clean and rinse the hollow centre as well as the outside, then allow everything to dry fully before storing.

Tip: Set your lube within easy reach before you settle in. A fresh top-up when you need it, a comfortable position and an unhurried pace give you more room to enjoy those curves.
