As Liquidsky noted, I did not want to do any enemas myself to prepare before my friend visited as I don't like doing enemas alone, and I wanted to save the anticipation of gettng enemas again for when she visited. When she visited we chatted and she understood my reluctance to start right up with the usual "therapy" , but as expected she said she did not want to finish her visit without me getting the "good" i.e. large enema she insists is needed for a proper cleansing.
Fortunately she noted I was particularly tight when she first applied Vaseline and slipped in a preliminary suppository. This lead her to do more anal massage than she was usually willing to do. I loved the attention as she helped me relax and loosen up. When it came time for the bag with the large nozzle, she was more playful than usual and slowly slipped it deep inside without issue. To my surprise, she did not start with a SSE, instead she used a mix of salt and soda which I found very comforting and much easier to hold. I took a bit more than a quart lying on my belly and was feeling some pressure, so she let me go right away. Then she asked me to assume the knee chest position and administered another, this time about two quarts. I was surprised she did not insist that I hold this, but when I returned from the toilet I could see why-- she had her regular 3 quart SSE ready to go.
Surprisingly this was quite easy to take, but difficult to hold, and this time she really insisted. Instead of holding my cheeks together as she had done before, she held her gloved finger in my bottom while I squirmed until finally I went to the toilet. I wondered if I was done, as she always had followed a SSE with a rinse. In fact this was still the case. She did note that my bottom might get a bit sore from more enemas than usual, so she was particularly liberal with the Vaseline inside and out, but then gave me a deep plain water rinse, again in knee chest position, working the nozzle to ensure it went in deep. Overall an excellent and thoroughly enjoyable cleansing. Of course I would have loved it she had taken matters in hand and worked my inevitable erection when in the knee chest position as a reward for taking her deep cleaning, but this still doesn't seem to be a "therapy" she is interested in providing.
