Giantess's new pet [4k]

Omg i cant believe there is a tiny little man here in the house! he must be the one eating our food and not a mouse like we thought! what should we do with him and his icky little hardon? hmm after some humiliation i think we should go to the store and buy a little cage to keep him in. i have a great idea on how to profit off of him. we will make little obstacle courses for him to run through and we will post them online. everyone will love them. looks like you're our newest little pet now.
