In honor of NNN here is a nut based model. I'll leave it to the reader to decide what NNN stands for. Play with the strength as needed, I generated mostly with 1.2 strength. Rear view probably won't work but might address that in V2.

Got the general idea from a chat on this site. Aids in the generation of nut sacs that are double stuffed.(4 testicles, 1 sac)

Trigger word: quadsac

If you are getting multiple cocks then you can try adding "multi_cock" to the negatives. I tagged most if not all the mutli-cock images so that should help.
