Natsumi FMG (Patreon)

Female muscle growth of Police Officer Natsumi Tsujimoto  from Anime You're Under Arrest 

this was suppose to be animation at first but it had very little process progress during few years, a released 5 step sequence is much better than 15 frame of animation that never done 

taking a second look at the result here, i think it still could be animated, a very wanky one, i may still give it a a try
