Its a mpreg???? How? Theyre not abo aren’t they

MC got a special constitution. This isn't the first time I've read one of these, they're semi common in the Mpreg community. MC is just special somehow. Some claim hermaphrodite, some say new technology allows for male pregnancies, or fantasy magic. Some make up their own thing or reason. Some have MC eat a fruit, or have MC give birth to an egg.
