Kinks combined, cuckolding and ballbusting?

Hello everyone, so happy to have stumbled upon this wonderful collection of stories, my only issue has been trying to filter through for what I am looking for.

I'd really love to see more ballbusting stories where the owner of the battered balls is cuckolded or forced to watch his partner or other significant person being fucked. The emotional masochism of seeing other balls having fun whilst theirs are being hurt is what does it for me.

Does anyone have links to such stories here or can explain to me how to search for them? Or if anyone is feeling creative if happily supply some notes and inspiration for such a story.

Thank you for your time and I am looking forward to reading through more of these!
