A fat leather belt would be my choice. My Mistress dressed all in leather wearing this large belt and gives me 5 dies to roll twice. First for the number of strikes from behind and second from the front. She proceeds to put my legs in a spreader bar and my hands and neck locked in a stock device. Lastly she attaches a leash to my balls and cock and places the end in my mouth to expose my privates for an easy target. Her instructions are for me to not drop the leash or she adds 3 more strikes for each drop. If I cannot complete the punishment from back and front, she will lock my cock and balls in a Chasity cage of her choosing for a length of time of her choice to punish me for not taking the beating correctly.
