Saw a picture on ballbusting hentai SR

Okay so I saw this picture on the ballbusting hentai subreddit and where it's a girl walking but you can see like an x-ray into her shoes, she has 2 sets of balls crammed into her shoes and I think it would be an awesome idea for a story.
A story set in the future where guys can remove their balls (and penis if wanted) without being castrated... Like a portal, so while they are removed from the body they can do everyday things (like they would have to put their penis in a toilet or something and they can pee whenever).
I think it would be a sexy idea because a guy could give his balls to a girl to do with as she wants, or make his balls the collateral for being able to enter locations.
