The final touch is to lock him in a proper full chastity belt so he can't do anything abut the endless torment which follows! . . . . . . And best of all . . . . . Do it to me!!!
Good video but it would be even better if the panties were larger and could be filled with nettles all over his erection so that he only feels the stings there and isn't distracted by having his legs stung. Better still if he's in split crotch panties under loose ones stuffed with nettles so that it's only his cock which gets stung.
