Yes, your ass can take a longer, thicker dildo. Since you have mastered the art of deep dicking your ass, move up to bigger ones. I start with my well-lubed favorite dildo to prepare for my bigger ones. I ride for about ten minutes before switching. Applying more lube is essential to make the thicker, longer ones slide in all the way. The internal stretch is mind blowing! I have cum hands free from this. My collection of dildoes and plugs are all over 2" in girth and at least 15" long. My thickest is 3.75" in girth and 14" long. I save it for last. Sometimes, I insert it full length and wear underwear to keep it inserted. I'm able to walk aroundike that, using both hands to masturbate. I have even fallen asleep with my ass stretching monster inside me after cumming half a dozen times. I always wake up with a rock hatd boner!
