CW: Conjoinment, PTF(?), Micro, Body Horror, Loss of Autonomy

Imagine waking up, realizing that the world is way bigger than before, you tried to walk, but you cant... you looked behind, you saw an anthro insect of unspecified species with the same size as you are, you looked below, you saw your torso merged with the abdomen.

Yep, you're conjoined to a female anthropomorphic insect's abdomen, reducing you to a passenger.

I got that idea from those "rеаr taur" art in which a person is conjoined to the back of a creature, facing away from that creature's head.
