yeah i loveeeeee nanahiosagi and kunichigisagi. it actually changed my life and is to this date my favourite. i also like aikukaisagi but that is more of an isagi sando and less of a poly ship. i dont consider ships where its just two characters fucking one a poly ship. a poly ship to me is one where they all like each other. So if by poly ships you mean sandos i have tons: eg aikis, honnis (again), aingis, sernis, kinsis, ngrois and pretty much anything where you have isagi taking it up the ass twice. but for specifically poly ships i just have those two i mentioned earlier and maybe nagibachisagi. but if you have any you really love and wanna share with me im all ears
