Bottom Line Rubber Butt Plug Black Model 4 fills your ass completely with 60mm of thick girth that stretches you wide. The 180mm height gives you deep penetration that hits your prostate just right, while the soft rubber flexes with your body as you clench down on it.
When you slide this thick plug into your ass, the soft rubber compresses slightly during insertion then expands to fill you completely. That 60mm diameter creates serious stretch that makes your hole work to accommodate it, sending waves of fullness through your entire pelvis. The rubber material gives just enough to be comfortable but stays firm enough that you feel every millimeter of girth.
Your prostate gets constant pressure from the curved head as you move around with this plug buried deep. Each step, each shift in position creates new sensations as the plug moves inside you. When you're ready to cum, that fullness amplifies every contraction - your ass clenches around the thick shaft while your prostate pulses against the curved tip, creating orgasms that feel like they're coming from deep in your core.
Use plenty of quality lube and start by pressing the tapered tip against your asshole. Push steadily while relaxing your muscles - the soft rubber will compress slightly as it enters, then expand to fill you. Take your time working up to the full 60mm width. Once the widest part slides past your sphincter, your ass will pull the rest in naturally.
Rock your hips to move the plug against your prostate, or press the suction cup to a wall and back onto it. The thick shaft creates incredible friction as you slide up and down, while the curved head targets your prostate with each thrust. Keep stroking your cock while riding it to build toward explosive hands-free orgasms.
This plug works best for experienced anal players who can handle serious girth. That 60mm diameter isn't for beginners - you need to be comfortable with thick toys and have worked your way up to this size. If you love feeling completely filled and stretched, this delivers that sensation perfectly. Couples can use it for preparation before fisting or large strap-on play, while solo users will appreciate the hands-free riding options.

This sits in the advanced category of our anal collection due to its substantial 60mm girth. While many customers start with smaller plugs, this model serves those who've graduated to serious stretching. The rubber material makes it more affordable than premium silicone options while still delivering body-safe materials and reliable performance for experienced users.
The curved design and substantial length make this excellent for prostate stimulation, though it works differently than dedicated P-spot massagers. Where specialized prostate toys focus on targeted massage, this plug provides constant pressure and fullness that surrounds your prostate. Perfect for those who prefer overwhelming sensation over precise stimulation.

What caught me off guard was how much the rubber material compressed during insertion - I expected it to be firmer. Getting it in took patience and lots of lube, but once past the widest point, my ass basically inhaled the rest. The fullness hit immediately, creating this deep ache that spread through my pelvis. Moving around with it in was intense - every step sent little shockwaves through my prostate. About ten minutes in, I pressed it against the shower wall and started riding it properly. The suction cup held perfectly while I worked myself up and down the shaft. My breathing got heavy as that thick head dragged past my prostate on each stroke. The whole session lasted maybe twenty minutes before I came harder than I had in weeks, my ass clenching rhythmically around that thick rubber shaft. The cleanup was straightforward - just soap and water since it's fully waterproof.
