The New Toy by Nairny (Archive Link)
A bit of a special belly-inflation story by Nairny on DeviantArt about Nancy and her plans for the party she hosts at her house. She recently bought a new toy, but while using it, she gets interrupted by her completely drunk friend and dragged to the rest of the part. The problem is, just, that the magical toy has quite a bit of cum its going to pump into Nancy.
