I love that there is tentacles fooling around with her, but what if there was also other kinds of creatures being able to have fun with her.
Creatures like:
Worm or larvae (can be a mini slug like worm that is basically a cut off peice of a tentacle for reference), they would be able to crawl inside her and become unbirthed, causeing her to store eggs or more of those worms when inside.
Womb hugger (Face hugger, but can attach to the front and back too)
These fellas would attach themself to her and lay/ implant eggs like in xenomorph, but not in a gruesome way.
Spiders or other kinds of bugs could also be a interesting idea.
Basically i think we need more monster encounters too for breeding purpose.
