You are totally not pregnant. [Ftm4ftm]

You cannot possibly be pregnant.

And yet here you are, tummy distended, filled with pressure and movement and discomfort and ... arousal?

Tell me what's growing inside you. Eggs? Larvae? Tentacles? Fungus? A demon's child? Alien spawn?

And why were you so sure you couldn't be knocked up?

20+ and reasonably literate, please. All genders welcome.
