I've had the time and privacy to do enemas near-daily lately, so my last session was a few hours ago earlier this morning. I filled my gallon bag up to the brim and took a series of six enemas, starting with 3 qts and working my way up to 3.5 by the end. I've found recently that while I usually take larger volumes standing up or kneeling, I've been able to easily take nearly a gallon laying on my back, relaxing and feeling the warm water flowing in through the white douche nozzle with the bag hung high. By my last bag, there was only a little left at the bottom of the bag by the time I decided to stop. I might have pushed myself a bit further and drained it but the pressure was starting to get uncomfortable.
While I usually don't spend any time retaining enemas this big, today I wanted to try something to help with retention. I have a black inflatable buttplug toy that I've really enjoyed during anal play, so while holding about 3.5 qts of water, I gently eased it into my rectum and held it there by the base. I gave the bumb one squeeze, then another, then three more until my ass felt very full. I've given it up to 12 pumps while playing with it before, which expanded it to the size of a grapefruit, but five squeezes is more like the size of an orange - and my colon was already very full of water. Once I relaxed, I found that the plug simply stayed in place, and I could comfortably hold what's for me a very high volume. I was able to relax my belly and admire my very pronounced distension in the mirror. Even though I still felt very full inside, I comfortably walked around the house with the bulb dangling between my legs, cradling my pregnant-looking belly in my hands. After about 20 minutes of doing various cleaning up around the house, with my big water belly sloshing around, the pressure inside was starting to get a bit uncomfortable. I deflated and removed the plug while sitting on the toilet, and finally released it all.
By now my returns were running almost clear, so I decided to spend a bit of time playing in the shower with my 10" silicone shower nozzle attachment. I turned it to a gentle warm flow and slowly worked the entire length inside, until the last few inches were in my sigmoid colon. While standing and holding the nozzle in place, I relaxed while leaning against the wall and felt the flow of water filling me deeper and deeper. When I felt I couldn't take anymore, I released all the clear water around the nozzle while holding it in place. I repeated the process several times, fully filling my colon with water before pushing it out in rapid and large gushes. I was able to get very full working my way up to progressively more water, and I was able to feel even the upper part of my belly starting to stretch out, which usually means I've completely filled and the water is starting to push at the limits of my capacity. Once the pressure forced me to quit, I slipped the length of the nozzle out and sat on the toilet to release. It was an explosive expulsion for sure, as several quarts quickly found their way back out, and the feeling of the release of all that pressure was incredible. I'm spent!
