alright. if ritsu gave soubi a piercing because he's a sick perverted old man where would he put it...
arguments for belly button piercing: it's cute, it's easy to do, it's good for decorative jewelry so ritsu can dress him up (which we know he likes to do...)
arguments against belly button piercing: i probably only want this so bad because i read kitakawa at an impressionable time in my life. this is not an actual con and there are no cons to this
arguments for single nipple piercing: fairly simple, very cute, it's sexual torture chic and he'd love that
arguments against single nipple piercing: ritsu strikes me as a man who likes symmetry and i don't believe he'd leave it to one
arguments for some kind of genital piercing: he's a gross perverted old man ofc he would like this. also it's cute and sexual torture chic to the max. and best of all it'd be a way to haunt soubi forever because he could never have sex without reminding himself of the claim ritsu has over him ^_^
arguments against some kind of genital piercing: difficult to do. uhhh basically that's it
