She's out of control! (Patreon)

Firecapt guessed correctly. This sequence by The Muscle Girl Fan was inspired in part by the David Cronenberg The Fly Starring Geena Davis and Jeff Goldblume.

What I like about TMGF is how beefy and thicc he can make his gals, but yet they're still so damn curvy in the right places. He can make em massive and feminine. Love it!
