I come home to find my vial of shrinking potion is empty that I was going to use on my evil boss. My roommates car is there so I know that he is home... oh great he drank the potion. I look frantically for him everywhere, finding him under my dirty panties. There's nothing that will reverse this and he will be tiny forever. For his punishment I'm going to tease him with my body knowing he has secretly wanted to fuck me all along. After I think he's been teased enough I put him into my panties where he will stay forever.
