My New Microphile Girlfriend

When Rosie entered Greg's house, he was a six foot tall man. Shortly after, he is eye-level with her exposed navel, and that's just the beginning of their night together.

The man is open-minded enough to indulge his new girlfriend's weird fetish, but he has no idea how tiny she really wants to make him. But when she sprinkles the shrinking powder all over her curvaceous body and invites him to consume it, it will be hard to resist. Even when he's only going to become smaller.

How many sizes and situations will he have to experience before Rosie is truly satisfied?
