Spider upgrade

After looking through a few of the chips she found one that peaked her interest. “Alright I would like to try out the spider chip”. Samus asked. Seconds later, a panel on a nearby wall opened up, dropping a small chip from a tube.

Inspecting the chip she sees a silhouette of a spider on it, Moving her hair back she placed the chip in the slot on the back of her neck, she wonders what it will do once she installs it.

Will it give her the powers of a spider to climb up walls and swing around like a certain friendly neighbor spider person? She doesn’t have to wait long as she felt a warm tingling sensation spreads to her lower half.

It felt odd as she felt weak in her legs and tightening in the back of her suit, she turns around and gasped as she sees her ass filling out growing rapidly.

“What’s going on?! Why is my ass growing?!” Samus yelled out as she cupped both of her once small but firm ass that was now rapidly growing bigger and bigger.

Soon enough her legs gave out on her as she hit the floor hard, her ass cheeks making a loud squishing sound as it smacked against the metal flooring.

she looks back at her now enormous dump truck sized ass cheeks as she couldn’t move from her spot. Soon she sees her legs withering away into nothing as they retreat into her zero suit which starts to turn colors from its usual blue color to now a shiny black, with a red diamond shaped forming on her back, as well as taking material away from her arms exposing them as well as a diamond shape window to her chest.

The transformation isn’t over yet however as she feels more growing around her ass as something begins to poking out of the sides of her asscheeks.

It wasn't long before she sees a 8 slim limbs coming out coated in the same shiny black material as her suit is, as well as feeling her asshole puffing up before it could be seen between her enormous asscheeks behind her.

She was now a massive spider woman.

Samus had just gone from human to half-human half-spider monster girl. She tries to stand up on her new legs, which takes a moment to get used to before she manages to make her way to a close by mirror to examine herself the best she could.
