You drank the potion Aria gave you, a strange feeling welling up inside you as both your upper body as well as your spider's body began to shiver.
You feel that your spider's body was starting to grow in size, while your torso was barely changing at all. Your 8 strong spider legs were stronger and more toned. Your spider abdomen was also growing and has a slight change on it. From your spinneret, a tentacle sprouted out, lengthen, had a mouth with the teeth are arranged along the length of the tentacle and located inside it. On the abdomen, a hole appeared with tentacles inside, like the tentacles had merged you with the spider.
Things only get weirder as your vagina grew longer when you felt a surge of pleasure risen over you. Right after that, you had an orgasm when semen gushed out from your vagina, followed by a few more tentacles squirting out from inside your vagina. There are 8 of them in all, their length is longer than your clitoris, their width is almost your arm. The slimy discharge from your vagina lubricates them while they wriggle in front of you. The orgasm made your nipples ooze a little milk, your breasts tighten with excitement.
"What happened to you? You look scarier" Aria feels scared that the potion she gives you is causing scary changes to her, but the transformations above all make you feel very good and great. Your entire body feels energized, with energy that can satisfy your desires at any time.
You groaned for a moment before the change was complete, you regained consciousness as you examined your spider's body once more. Your spider's body has grown considerably, with powerful legs supporting this entire body. You looked at the spider's belly, with a swinging proboscis in the back, looking for prey to absorb. You then looked towards the opening hole behind you, which was exactly the same thing that joined you to this spider's body. Then you looked down, as new tentacles were sprouting from the inside of your vagina. They were flexible, and powerful when you try to move them with your thoughts. When you tried to lift a nearby rock, you groaned when it hit the stone, but after a while, they swelled, exposing the muscles inside, making the stone feel lighter than before. You are surprised to find that your desires only make them stronger and stronger. You gazed at your remarkable body while Aria was standing in the corner, terrified of everything that was happening.
You then turned to look at Aria, who was witnessing the whole thing that was happening. With the new functions you had, and the strange thoughts were rising in you, you had an idea.
