You're on a roll @Loveitkinky!
Currently, I have my SNCMAX3 inserted and I have about half of my black 4-liter bag emptied into me. I think I may stop, drain, refill the bag and see if I can take the whole thing.
AN UPDATE:
The battery on my phone was nearly dead, so I didn't update at the time after a series of productive enemas. I did stop and drain out the first enema. After a productive emptying, I refilled the bag and relubricated the nozzle. It took just over 1.9 liters to refill the bag. And the nozzle slipped back in easily.
The next filling went a little faster and deeper. The bore on my SNCMAX3 is larger than my other nozzles and so it can fill me very fast. I kept it dialed back a bit so allow the enema to move further up my descending colon and to hold it for a bit. The bag was much more empty than the first and after shutting down the flow, I rocked back and forth on the nozzle to enjoy the expansive filling of the nozzle in my rectum.
I eventually pulled the nozzle to allow the second enema to drain out. The feeling of the warm liquid draining out of my descending colon and the softened "contents" was exactly what I was wanting. I added warm water back to the bag to refill it. It took 2.7 liters to bring it back to the top. I decided to switch nozzles to my DBLBL-XL nozzle. It is also a deep and large nozzle that seals the top and bottom of my rectum with 2.5 inch diameter retention balls. This time I let the flow be at its maximum and the warm enema quickly filled the cleared spaces within me. As my descending colon filled, I slowed the flow to enjoy the fullness and to feel the liquid flowing across my abdomen in my transverse colon. The bag got pretty flat but not completely. I held it to a marvelous orgasm and then allowed it to drain out of me. I went to sleep almost immediately after draining the enema out of me and cleaning up.
A SECOND UPDATE:
After being thoroughly cleaned by the series of three enemas. I proceeded to brew 4 liters of coffee and place it in my black enema bag to cool. Although I let it cool for over an hour, it was still pretty warm and warmer than I would want to take it at full flow. I let about 1.5 liters of very warm coffee trickle in over a 10 minute period and held it for 13 minutes before releasing it. This helped allow the coffee in the bag to cool further. I reinserted the nozzle after lubing it again, and allowed the remainder of the bag to flow into me over the next seven minutes. It was still warm, but cooler than the initial coffee I instilled. Targeting a 30-minute total time for the second session from beginning of filling until release, I held that volume for 23 minutes before letting it go. More enemas in a 12 hour period than I;ve experienced recently.
