For me it is hard to say which is the best part. When I insert the SPD3.0 nozzle from Silicone Nozzles in me, I feel great. Then the water starts to flow. That is wonderful. Then I get the release and getting cleaned out. All of which is great and feels so good.
Then I go for another filling. Now that is even better than the first filling. In goes that huge nozzle, hotter water, I get more water in me and the feeling of getting filled up, the nozzle helping to fill me up is one of great satisfaction.
Then the nozzle come out, water and the emptying of me is wonderful. Usually the water is not clear then, so I get another filling of water. Again in goes that huge nozzle and the feeling is one of great joy, water goes on and rushes in. I have an inline pump which if the water is not flowing well, I can pump myself up with more water. Then I check the flow meter, by then the water is flowing in and filling me up. That is wonderful. I get a nice hard on then and the water runs higher and higher. I wait till the last possible second and then go to the toilet and release. The nozzle comes out, water and by then the water is just about clear.
I refill my enema buckets each time I fill up. This time I make sure the water is very warm, almost hot and then the last filling begins. The nozzle goes in, then I release the clamp, the water starts to flow, I pump the bulb some to get a good flow going, make sure the water is flowing strong, wait a bit for my erection to come up and then as the water flows I start to masturbate. As the water gets higher and higher, I get hard and then release. I cum and then move to the toilet to expel. Out comes the nozzle, then water, almost always clear and I am clean and satisfied.
I sometimes take a nap after a long enema session, I usually try to stay awake in case there is some water that moves back down after the last expelling.
Then I drain my enema buckets, if they were not already drained in me, make sure the toilet is cleaned up and I pick up all the towels. I find I am refreshed, feel great and satisfied that another enema is in the books as a huge success.
So the nozzle, the filling are the best part, you have to release the water out of you to continue and that always feels good. So to me the whole enema experience is an event of joy and the best part is I can do it again in another day or two. Ah yes, enemas are great.
