6 Best Butt Plug Stretchers: Buying Guide

A butt plug stretcher can look like a small step up on paper, but its shape matters just as much as the size. A narrow tip and a long taper spread the increase in width over more of the plug, while a shorter taper reaches full width sooner.

We reviewed 13 butt plug stretchers and chose six for this guide, from smaller starter options to larger sizes. We compared five things across all 13 models: diameter and size progression, tip shape and taper, material firmness, base stability, and ease of cleaning.

Each review explains where the plug fits in that size range and what sets its shape apart. That way, you can see which picks make sense as a starting point and which offer a modest step up from a size you already know.

2. Dragon Fantasy Hollow Butt Plug

Of the six Dragon variants, we chose the MK5218 for its uneven, claw-like tips and the raised scales along the front. Orange and cream streaks run through the dark silicone, and the broad, rounded base leaves a clear rim to grip.

The tips sit at different heights around the hollow opening, so the rim presents several distinct contact points. Farther down, the raised scales concentrate the texture along the front. That gives the MK5218 a directional feel on paper: the angle of the plug could affect where those ridges are most noticeable. The grooves between the scales and the gaps between the claws also take more attention during cleanup.

The MK5218 is a large hollow plug for someone who wants a more pronounced surface texture. At about 80 mm across its widest point, it’s close to the Clear Hollow XXL, which has a smooth, uniform shoulder. The Dragon makes the most sense for someone already comfortable with a similar width who wants to try a sculpted shape.

3. Silicone Massive Hollow Expanding Anal Toy

Two matte-black silicone wings curve outward from a narrow neck above a flared base. The wings have broad, smooth faces and rounded tips, with a deep opening between them that leaves room for each side to flex inward. That opening also gives you an extra surface to rinse and dry during cleanup.

The listed width is the distance between the two wingtips at rest. Going from Medium to Large adds 20 mm to both the wingtip span and the overall height, so it’s worth checking both measurements before sizing up.

The split top is the main reason to choose this model. The Dragon MK5218 gets its shape from several uneven claw tips and raised scales along the front. This model has two broad, smooth wings with room to flex, which makes it a better fit for readers who already know they’re comfortable with a wider plug and prefer a smooth surface with an open profile.

4. Anesidora Bars Stainless Steel Hollow Plug

The Bars has a polished stainless steel frame with a small ring at the top and a wider ring at the base. The rods angle outward to form the shoulder, then bend inward at the neck. The shoulder is made up of separate, rounded bars with open space between them. That’s the detail that sets its contact surface apart from a smooth-walled plug.

Moving from Small to Medium gives you a noticeably wider shoulder and a taller frame. Both dimensions are worth checking when you’re between sizes. The open sides give you a clear view of the interior during cleanup, including the spots where the rods meet the rings.

The Bars is the rigid, open-frame option in this lineup. Its Small measures 58 mm across the shoulder, close to the 61 mm Clear Hollow Large. At a similar width, the Bars has spaced steel rods and the Clear Hollow has a continuous silicone wall. The Bars makes the most sense for someone already comfortable with that width who prefers a rigid frame and wants to try a different contact surface.

5. Asslock – Locking Anal Plug

The Asslock has a rounded, polished stainless steel head, a crossbar at the rear, and a small external padlock. When the head is closed, the panels sit together to form a rounded profile. As they spread apart, the gaps between them become visible and the outer surface becomes segmented.

The listed width goes from 1.57 inches when closed to 2.36 inches when fully open. The steel panels have little give, so the closed width is the first measurement worth checking. The spaces between the panels and around the moving parts also take more attention during cleaning.

The Asslock’s defining feature is a steel head that changes width within a single unit. The Anesidora Bars offers three fixed sizes with an open steel frame, while the Asslock uses moving panels to change the head’s width and shape. It’s best suited to experienced buyers who already find the closed width comfortable and specifically want a mechanically adjustable design.

6. Blossom – Rotating & Expanding Prostate Plug

The Blossom has a black silicone head shaped like a flower bud, with four ribbed petals ending in rounded tips. The shaft curves into a wide base that sweeps upward at both ends. The petal tips sit apart around the head, giving it an uneven profile.

The head is listed as rotating through 360°. As it turns, the raised petals change position around the head, so the contact points can shift while the shaft stays in place. The flexible tips also have room to spread. You can adjust the settings with the on-device buttons or through the app.

The Blossom’s main draw is the movement of its petal-shaped head. The split-top silicone plug earlier in the guide has two smooth wings with room to flex. The Blossom adds powered rotation to a four-petal design. It makes the most sense for someone who already likes the shape of a curved prostate massager and wants contact that changes position during use.
