If you’re a regular Spectrum shopper, you probably already know about the Polka-Dot Jollet, a girthy dildo that conforms to the pubic bone during vaginal use. For those who like butt stuff, the Luna by LuzArte's shape is the rectal equivalent!
With 1.5” max diameter and 6 inches of insertable length, it’s not a small toy, but the taper and glossy surface make it relatively easy to insert. And its scalloped base is both adorable and useful for gripping. Just make sure to go slowly and listen to your body. When I used the plug, it rotated to the most comfortable orientation on its own.
Though the Luna is marketed as a butt plug, I think it’s way better as a playtime dildo — enjoyable for significant internal pressure, with small thrusts and little stretch at the sphincter. And while it’s a lot of fun to play with as is, I think its shape would suit a dual-density version in the future.
