The morals of the readers will be tested. It is certainly something which wrong, as your conscience should tell you. Anyways, majority says no, and I do hope that you do not stick with the minority.

Unless the male characters are seahorses and pipefishes of the fish family Syngnathidae, mpreg isn't possible and it would be hard for me to believe the story. I know that it is fiction, but readers need to empathize with the characters. I can't do that if I don't think that mpreg is possible.

Well, unless you are writing a fantasy or a paranormal fic... wherein they are half fishes or something... ehe

It's just... wrong.

i voted no... but i actually dont mind. It depends how the story goes. ^_^
