Peter Parker, Arachna Queen (From the 3D Archives) (Patreon)

Here is a concept I've been working on for Spider-Man, where the spider-bite that originally gave him his powers later causes him to mutate further, transforming him more and more into a mother spider. 

His body becomes more and more arachnid and monstrous, growing spider-appendages, an arachnid exo-skeleton and bio armor, transforming his young male self into a curvaceous older woman with red skin and 8 eyes. 

The first picture is the most recent MILF version, and the bottom 3 pictures show the progression as Peter is aged dramatically into a GILF and transforms further into his final form.
