This Rhino MK.II is a 2x5.5 inch 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 the Dock 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 four 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.
 
Works well with the Dock, and some prefer it as a handle to the other toys.
