I love my XL inflatable dildo deep inside my butt. Pump it up about 50 to 60 times, before a fist slides in. Lots of fisting lube needed and poppers to sniff on. Perfect!!!
I use my XXXL inflatable while I'm flushing out. In between flushes I use the inflatable to stretch. After each flush I pump. So when I'm ready, so is my hole.
