When i was younger i was experimenting alot with my anal. I stuffed it with all kind of objects i could find. I tried to explore how big things i could get in. I tried bottles, pencils, and all kind of roundshaped objects. I also tried to get my whole fist in but i never succeded completely. My ass got really sore sometimes and i tried to stop doing it because i didnt want to get hurt. The biggest thing i got in my ass was a big shavingfoam bottle. Not much smaller than a sodacan. I also tried cucumbers, carrots, a knife (!), brushes.
The feeling when a big objects gets in is amazing.
Finally i quit trying the more sharpedged objects. And today i only use a dildo and a buttplug.
