would like to see options, not only the deadly habitation of the mouse in the asses ...)
for example, with a big dragon, it would be possible to make a variant of how she went out with a mouse in her anus, and when she came to the locker room she found her huge cock in the locker room ....
realizing that there is something else in the ass, she would try to release the mouse in the restroom,
as a result of the release of the anus from a foreign object, she would find a small mouse, and would decide to let go or return the anus, / for example, the mouse is active then let it go, / if it is lying around without strength ... then shove it back but on the other side and go to yourself home)
