You have volunteered  to participate in a clinical trial for a Penis growth serum.  Prior to administering the serum, Dr Goldenlace needs you with empty balls, so she jerks your tint 2 inch cock off whilst getting you excited a the prospect of ending up with a dong in between your legs.  You take the serum and shortly after you start to feel awful. Before you know it you have shrunk down to 4cm just shy of 2 inches! Unsure of what to do, Dr Goldenlace calls her boss and explains the situation and it is agreed that you will remain in her care for observations for 24hrs. She promises she will bring you back to normal size again with the help of a nother team's experimental body growth serum and takes you home in a cat carrier. once home she gets out of her clothes in front of you, and tells you her boyfriend will be coming around. She administers he growth serum, in the hope you will grow back to normal size. You are put back in your cage and her boyfriend comes over to fuck her. you see it all and it makes you hard. She notices and treats you to another orgasm, since we don't know if you will ever make it. After a while has passed and you remain tiny, she calls her boss and is pressured to dispose of you, since the clinic has a reputation to uphold. No one can find out about their fuck up.  she agrees to make you disappear.  You panic and she pins you down and tells you that she is going to swallow you and bring you back when a reversal serum can be made (lies!) she pops you into her huge gob and swallows you down in one gulp. she calls her boss, rubbing her full belly, telling him "it's done"
