I feel like this strap-on could probably fit someone up to 48 inches, so it can fit some plus sizes as well as straight sizes. I was pleasantly surprised by how well it fits and the extra rings of different sizes it comes with, so you can switch out the dildo to a thicker or thinner dildo. The dildo is a soft silicone, but not jelly. It feels amazing to use this strap-on with your partner. I rubbed my clit against the strap on the interior as I fucked my Mistress. She absolutely loved the material. The soft silicone made it easier to take for people newer to anal.
