I have trouble shaving my ass and my step uncle offers to help me and ends up touching my pussy.

My step uncle is a very helpful person, always willing to lend a hand. This time it was my turn. I've always had a really hard time shaving my ass because I have a big butt and there's always some hair left. So he offered to help me, but I think I was too tempting, and he ended up touching my juicy pussy and putting his fingers inside me.
