This situation is very essential for most of the enema-enthusiasts I believe.
I am 68 years old and get hard at once, only thinking about the word enema. The feelings are very strong.
I think is is stronger than even the thought of having sex with a nice lady. Some days, even at my age, I can't stop thinking about enemas and I just have to do it, even in the middle of the day. Nothing can stop me. I am hard at once and it is hard in the beginning and long into my first 2 first liters.
Then it falls down a bit until I have taken all 5 liters. The enema in itself is so good and I focus on this. I can be really wild during the play, doing it again and again with different nozzles, different tubes, irrigators, and bulbs. I have many of them and it builds me up to a higher and higher level.
When I decide to have an orgasm, everything is over and I became "normal" again. In the evening I can start up the same thing again but only if my wife is out of the house. I do not like to show myself in such a situation.
I am 68 , 😘 and crazy in this game. I can still get off two times a day, because of the enema thinking inside me. I love Enemas.
