It took years. She thought the whole enema thing was kinda weird.
I stopped making a fuss about it and finally got her to submit.
We were having sex and I started to tie her hands to the bed posts. She really got into it. Then came the blind fold. I had a nice warm enema prepared without her knowledge. While masturbating her, I inserted the nozzle and gently let the water flow. She loved it.
Once full, I pounded her ass until she came all over the bed..
