My first bag enema was when I was ten, staying with my grandmother. I took about half of the bag, about a quart, which was the biggest enema I had until then.
My siblings and I received enemas from a douche/enema bag an adult rectal nozzle from the beginning. At first, we had no idea how much mom, grandma, or our aunts gave us. Starting around age five or six, mom started giving us enemas laying across our bed together using either a two-quart open or closed top douche/enema bag. Giving each of us a third of the bag. Then a year or so later, she switched from her two-quart bag to her three-quart pumpkin bag. Giving each of us a quart each. Changing again, when I was eight, back to her two-quart bags. Only this time, we each had to take the amount she filled the bag with by ourselves. When that happened, it was difficult to tell how much mom was giving us. Around the same time, our teenage aunts, who were responsible for giving us enemas at grandmas. Like mom, shared a three-quart pumpkin bag between us, switching back to a two-quart bag that we had to take by ourselves. On top of that, grandma told the girls to switch the adult recital nozzle they had been using, to a long-curved douche nozzle with a bulbous head. The first time the girls used it; it scared us a little. However, once it was finally inside, it really felt good, and we all liked it. Over the next couple of years, the volume slowly increased, until we were able to take a full two-quart enema.
I was ten years old, when I finally took a full two-quart enema. We were at our grandmothers, as was routine on Saturday evening, our two aunts gave us a soapy followed by a rinse enema before our shower. During my rinse enema, that evening, I finally emptied the bag for the first time. And I know the bag was full, because I watched my aunt fix it.
