Lucy and Isaac have been working on a growth serum - with a very interesting side effect. Anything that takes it, gets horny. The lab team makes the decision that one of their own should be the first to human test subject - and they nominate Lucy. Already considered a nymphomaniac, Lucy worries that her sex drive may go into overdrive. While she and Isaac fool around as she continues to grow larger and larger, they decide the best option may be for him to get just as large . . .
