Yesterday afternoon. I provided more details in my blog. It consisted of three enemas. I started my smartwatch at the beginning to track my heart rate. I don't list it as an "Enema" because it ends up sending the data to several apps and websites including Strava. I went back and deleted the workout from several sites/apps, but stored the data for later review. I can see quite clearly from the HR data when the contractions show up.
The first enema was a 3.0-liter soapy/glycerin enema delivered from my black silicone 4.0-liter bag and held by my clear silicone DBC nozzle. I held it about 20 minutes before I really had to let it go.
The second enema was a 4.5 liter isotonic baking soda enema delivered from my red rubber 4.0-liter bag and held by my Silicone Nozzles Model-B nozzle. The rinse stopped the major contractions but you can see the up and down off my heart rate from my monitor.
The third enema was a 5.5 liter isotonic saline enema delivered from my 5.0-liter natural amber latex bag and held by my natural latex DBC nozzle. I had to take it in two parts due to the liquid holdup from enema number 2. After completely draining the bag, I carefully deflated and removed the DBC nozzle and slipped in my inflatable Vixen butt plug and inflated it to hold the final enema in for about 30 minutes. Near clear discharge from the final enema. Over the two hours my average heart rate was about 115 bpm with a peak of 135 bpm. Qualified as an "easy aerobic" workout.
I was cleaned out enough that later in the evening I inserted all 5 balls of the 2.6-inch diameter "anal beads" toy (for the first time) that I purchased last year. Slept plugged the remainder of the night.
