Trying to Insert My Fat 9,9cm Wide, Hard Plug -gape and Prolapse!

I've tried many times to get this huge, 9.9 cm thick, and very hard plug into my ass - until now, as of March 2025, without success! I think I'm on the right track and will have this thick thing completely disappearing into my ass in the next few months. Motto 2025: 10 cm in my ass
