You obviously are completely scared after seeing this and unsteadily wobble around the cave in a frantic panic as you try to sort your thoughts while thinking of a way to seperate yourself from the spider. However, in the back of your mind, you know it isn't possible. But pure desperation is dominating your thoughts at the moment, so you try and ignore this understanding.
Your body is so alien to you now that you are scared of your own reflection and shadow. For 2 days you do little else but wander the cave and cry inside the spider queen's chamber which you currently are using as a temporary home. You do not know what you are going to do from now on, and even contemplated whether you would even be able to return to human society as an arachnee, or if you will be turned away at the gate and stripped of your knighthood and even possibly your humanity and labeled now as a monster.
Your third day in the cave is a lot better for you. You finally manage to get a good night's sleep in, though in actuality, you slept durring the afternoon and not the night, but being deep inside a cave and all, you had no idea. However, you are able to calm down quite a bit. So you take this time to really get a feel for your new body, and find out what your new self can do, given that this is the body you will likely be having for the foreseeable future.
The first thing you do is check outside, and you do not even realize it is the dead of night, as your vision is now equipped with an incredible night vision ability. It looks to be around mid day and you believe it to be, with the moon being mistaken innitially for the sun, that is until you notice all the stars. You put it all together and realize it has to be night, and that instead, you can just see really well in the dark. Makes sense since the cave you are staying in has never seemed to have an illumination issue, even though there were no light sources to speak of.
You look at your reflection in a nearby pond. Your skin is a bit paler from being in a cave for 2 and a half days straight, and your lower half obviously is a massive yellow spider. Where your hips connect to it, a ring of white, hairs has encircled you. It kind of looks like you ade wearing a poofy, furry scarf around the sides and back of your waist.
But as for the front, all that is there is your washboard abs leading down to a moist slit that is seamed part way into the yellow body of the spider. It is only now that you realize you have been not covering your pussy this entire time, and yet you also feel no need to do so anymore. Your pussy slit also is longer than before and you imagine it can open up wider too.
You look more at your upper half first, noting how your D cup breasts have swelled significantly and now each are about the size of your head. Your nipples also are a bit thicker and longer, but not to an unreasonable amount that makes them look unnatural. Your hair also has grown longer too.
The only other significant differences to your human half are your eyes, which have turned to a glowing deep red color, with an additional 6 more of them having grown on your head. Your fingers are all capped with a hard chitin tip that all end in a point. Finally, your upper canine teeth have lengthened and slightly curved backward, becoming a pair of spider fangs.
Your lower half, of course is the spider. A massive yellow monster that now is part of your body. Your 8 legs are strong and powerful and all of it, save for the joints, is protected by a hard layer of chitin. The back side is able to spin out webs quite rapidly too. However you then suddenly shoot out a pair of webs from your nipples as well. The web from your breasts lands in the pond and just floats for a bit before sinking when you throw a few rocks at them.
You head back to what now is your cave, and simply ignore the hundreds of smaller spiders who all live inside with you as you no longer are enemies. Once back inside your chamber, you set yourself down and move on to trying out the first thing you had found out was unexpected about your new body on day one, but never got to investigate it further, your newly upgraded clitoris.
At first glance, it is just a normal clit. But there is qctually a hidden catch. It is just the very tip of a long tentacle, which is kept hidden deep inside your body. You cifcle a pointy fingertip around it, causing it to snake out of your pussy for several feet and raise up to just about boob height. As if it is expecting something from you, it wags side to side excitedly. It is very sensitive, and the slightly cooler air tonight is stimulating, sending shivers up and down your body.
You push out more of the tentacle and move it closer to your mouth before you begin lightly kissing it's tip. You wince a bit at the burst of pleasure, but push through it as you push your boobs around the tentacle shaft. As you continue to make out with your own clitoris, you are stroking the tentacle with your boobs. You havent masturbated in days, and are feeling quite horny due to having a "sex withdrawal". You wish Sarina were here. She at least would accept this new you wholeheartedly.
As if on queue, you begin to imagine her voice. Just her saying your name. However you quickly realize that it isn't just in your head, and that it is actually her voice coming closer to the cave. You quickly reel in your clit and run to the cave enterance where hundreds of spiders are all preparing to defend you. But you ignore them and simply run past them to get outside the cave opening. You didn't even put clothing on due to your excitement and pent up lust clouding your thoughts.
