Modelling & Sculpting Shinra Toy - Brainstorming

The Scarlet x Tifa project is a lesbian project so I've decided to create a dildo from the ground up. Specific to this project ,it has to be immersive ...but you guys already know that I try to fit it to the lore somehow :D

Idea and lore
So I've made some notes about the color pallets what the Shinra corpo uses and started with a simple model (1st picure). Up to that point, I only knew that it cover 2 features ,important for the next scene. It should include a feature connected with the lore/world and some fantasy high tech .

Everybody can manage to do 1-2 animation work
but whats unique about these two making out ?
Scarlet is a corpo elite. She has access to basically unlimited recources and is merciless.
Why she doesnt just ask prof. Hojo for some toys ,hence she is playfully evil minded ?
That's where this toy comes in action :D

Toy details
As a fan and the knowledge about the FFVII story ,this wasnt that hard.
I've planned in mako gems . They use it everywhere and Shinra is known to waste it for their own demands , especially energy .We mostly notice then from Clouds (Zacks) Sword as coloful round gems. Done :)

Shape
At first I thought I should ads them aside, but that looked more of a distraction on the side than helping ,resembling a strapon. Imo it looks odd on close ups . On the bottom was the final decision . If I would make them bigger ,I would risk other issues and distraction so I kept them between not to big and "oh nice balls " views :D

Skin
I took inspiration from evil prof. Hojos and his mutant creations. The skin is a mix of synthetic and rubber tissue . Its not exactly what I wanted to, be but close enough.Between the first picture and the last ones ,Ive worked on the shader to show more depth and generally made the object more veiny .

My two cents about the brainstorming :P

P.S: Something similar is planned with Rey and Bokatan
