Rubber balls

been trying to stretch for bigger toys and was suggested to use inflatable toys. One of them was to use those dollar store balls as sort of like a plug. Was curious if anyone tried it before and some tips on what to do for this kind of thing.

The dense foam rubber football shaped ones are good, too. Use plenty of lube though to make it easier to get it inside you. Let the the widest part stay at your opening until it's too uncomfortable and push it out. Soon enough it will no longer be uncomfortable and just feel good.

When i looked into those most of them have the air entry hole around the mid section. How would it fill that while its inside?
