both of them being stronger than rinne (or at least hiiro i feel) and easily being able to overpower him.. he’d feel so small. they force him to suck dick even though he is only 21. a little baby. they marvel at how cute he looks with tears streaming down his face. his hair is so fun to tug. he takes dick so well why wouldn’t they wanna rape him. he’s made for it. afterwards they would cuddle him and tell him they love him because they know he can’t possibly hate them ^__^
