Female Possession - Worm Unbirth 2 underlay

Tentacles that know about clothes and how to remove clothing bothers me.  Scientifically, it makes little sense.  How do they see in the first place?  Unless they are a demon with magical intelligence,  I assume they usually aren't intelligent enough to understand the concept of clothes.  Sure, if they were smart enough, they could learn from experience, but what about before that?

So I invented a new kind of tentacle/worm with a needle.  There have been tentacles in hentai with needles before, but they only inject a chemical, usually in the neck or nipples.  Mine's serves many natural purposes and makes more sense for hunting human females for reproduction/possession/food.

1- The needle can pierce clothing.  It would create an opening and shove the rest of its mass into the woman with pressure.  Humans seem to have evolved naturally to wear clothes, so why not have something that evolved to affect clothes?  The needle is found throughout the animal kindgom in real life.  I was partly inspired by the fact that snails have a needle for mating:

The ~1 inch diameter shaft of the creature can squeeze through the hole.  Once it has completely entered her body, the hole would shrink back to pin-size in some fabrics, making it harder for people to notice that it entered her body.

2- If a woman has a hymen, it can pierce that too to reach the womb.  Again, this makes sense biologically.  The tentacle/worm's instinct to enter the vagina should be aided by some evolutionary tools if it acts mostly on instinct.

3- It can also pierce the uterus itself to reach the brain.

4- The needle could plug into the brain and release chemicals to influence the host, or connect its own nervous system to control the host's body directly.

Anyways, in this comic the worm injects its own internal organs into the host, leaving behind it's outer body.  The host's body is now literaly it's own body.  They share the same skin.  I try to put as much visual information as I can to lessen confusion.  The last panel with the shriveled-up skin draping over the feet was a last-minute idea as I reviewed the rough draft.  I review each rough draft dozens of times.
