This Rhino MK.II is a 2x4 inch (wood joke) girthy dildo with the usual Funkit suction cup mount. While on its own it is not adviseable for anal play, if you attach it to an upcoming mount or another toy it should do you just fine. With a narrow front that quickly widens out to a 2 inch crown, followed by another three equally large ridges on the upper side for extra pressure on all the good spots, the Rhino is wide enough to push all your buttons.
