Mommy

You have packed your bags, ready to escape into the sunset with your beautiful Girlfriend. That is until your step-Mom finds your belongings all packed away. How dare you leave Mommy for that slut of a Girlfriend, leaving your poor step-Mother all alone. The Woman who has nurtured you for all these years.
Then all of a sudden "ZAP" – Mommy hits you with her new app which shrinks Men… and continues to shrink them when they get aroused.
