I'm still working on my mission to stretch out Zero's asshol.. (OnlyFans)

I'm still working on my mission to stretch out Zero's asshole. I hate being restricted in toy size and it's so much more satisfying to know he's full to the limit, to the point of discomfort! 

However, I'm becoming frustrated with Zero's progress! He needs to relax more and just accept what I tell him to take! Time for more punishments to motivate him!
