It is so big it only went up my ass after I had stretched my bunghole for a while with the biggest plug I have ! I had a friend push it in me & twist it while I gasped & moaned & prayed to god! After 3-4 twisting insertions I was already cumming. I dismounted this anaconda during orgasm & saw my asshole gaped wide enough for a tennis ball todrop inside my asshole without touching the fleshy walls of my rectum! Not for everyday punishment of your asshole but great for getting you ready for anal dp or a coca-cola bottle!
