looking for an episode

[Ramuzik]

about a year and a half ago, I was on Youtube looking at gender transformation videos when I came a cross an anime where a chubby guy came up to a elderly lady who was selling objects. he didn't like how he looked and the lady understood, she sold him a blank inflatable doll with no features at all. she said blow it up to represent your size and shape it to your will. He came home and looked at the doll, blowing the doll up like she said and then squeezed it, when he squeezed it the the air in the doll moved making the middle skinny and so did the dude but the air also moved to his chest like the doll and gave him breasts. he messed around with the doll until he looked like a skinny well tuned, well rounded lady! though he looked like a woman his voice never changed. then he went to a transgender club i think and that's all i remember of it. does anyone else know what i'm talking about? can someone help me find that episode or even better, the Name of that anime?
