You gotta start somewhere and there is no better place to start than the NS Novelties Renegade Sliders Trainer Kit. Training that bung hole is going to be delightful with the three differing size plugs of this kit.
They slide in smooth and the effortless penetration will feel velvety soft because of the satin finish but you can get them really slick with any kind of lube. Use the fitted suction cup base for some hands-free solo fun.
