Shade the Echidna/Mating Press (Patreon)

So this started off as just the first image in the set.

Taking an abandoned commission pose and changing the sonic girl from Mina to the much underused Shade the Echidna, Then i doubled the canvas size for a the full body shot.

Left with a full shot I was calling it done, then got struck with the idea... get her in a mating press. More steps were added as it went along.
