When Brie receives a large, attachable "finger" that enhances sensation, the first thing she does is stick it on her clit. It works as planned and she proceeds to use it and abuse it, losing track of time in the process. Her best friend and co-worker, Erica, visits to investigate why Brie missed work, and Brie shares her new toy with her, allowing Erica to experience penetration as the giver for the first time.

The time finally comes to return the "finger," but Brie ends up trading it for a little red pill that creates a sizeable growth between her legs. This thing is the real deal, and Brie knows exactly who she wants to try it with.

When Erica begins having trouble keeping her food down, Brie starts to suspect something's up. While she first fears her lover's gotten herself knocked up by someone else, she soon realizes the most likely culprit is actually... herself.

Their use of the magical pill will determine the direction of not only their relationship, but their lives.
