Unaware Giantess uses shrunken ex boyfriend as a buttplug

Description: I come into the room on the phone with my friend. i'm telling her i am over the guy i was dating because he was too small and well, just not getting the job done. i told him to get his stuff out but there seems to be some stuff around. thankfully he isn't around anymore. (except he is and i didn't realize!) i begin to undress and scratch and itch that is actually my shrunken ex. i accidentally push him into my asshole. i get off the phone with my friend and begin to fantasize what it would be like if i had kept him around as my buttplug. i get off on this idea and begin to rub myself. i eventually get off with him in my asshole without even knowing it! (ass play, anal insert, masturbation, removing shoes, pov bug views, up close vagina view, satirization)
