You volunteer your tiny body to science

You have volunteered to be placed in the bra of a model with macromastia for 2 years for research. To your misfortune, the beautiful big titted model has dropped out so you will have to be used for another study. You agree to go through with it because the money is good and you have been guaranteed a beautiful replacement. As soon as you have been shrunk down, you are owned by the research lab and will have to do as they say.  When you wake up from your shrinking ordeal the scientist is excited to tell you, she has found a replacement test subject. It will be her! She is excited to run research based upon how a tiny shrinky can survive in her sweaty sneakers for 2 years. you will have to hydrate from her sweat and eat the crumbs from her sockless soles.  as soon as she installs you into her sneaker you nervously wank, to soothe your predicament..... or are you just trying to make her shoes unbearable for her to wear by making them sticky with your cum.
