The US is a free country. at least at the moment… and people can spend their money any way they choose. Some choose to go to Aspen or Cancun and party all night. Some go to fancy eateries and drink expensive wines. After such adventures, they have little except the memories of their experiences
Others find ways to relive their own experiences. Consider a middle aged adult who secretly wants to relive THAT day in their early teen life… You came home from school, perhaps in a bad mood, and were not feeling well At dinner you just picked at your food which was not your usual habit. Mom asked you a couple of questions which you answered curtly. After dinner, you were sent to do your homework.
A while later, after you'd done your homework, you wanted to watch TV, but mom said no. She told you to go to your room, get undresses from the waist down, and wait for her. A few minutes later she came in carrying what looked like a hot water bottle, but had a hose attached to it, and a bath towel. She told you to put the towel on the bed and lie flat on the towel on your tummy. You did as she said. after all, you had no reason not to. A moment later you felt her spread your bottom and she inserted something like a familiar rectal thermometer. Then you started to feel a comforting warmth The warmth continued to spread in your tummy and you felt good, not realizing you were getting sexually aroused.
After a few minutes, you suddenly felt like you needed to poo The feeling rapidly intensified and you begged to go. You were allowed to run to the toilet and were amazed at what then happened.
Later in life, you desired to relive that experience of your first bag enema, and a part of reliving it is getting filled with the same, now vintage, bag that was used on you as a kid. So you buy a vintage bag for about the price f dinner out and play The next day, that nice dinner would be poo, but you still have a fun toy tp play with.
